Top 7 Mistakes Newbies Make Going Solar - Avoid These For Effective Power Harvesting From The Sun

[@LDSreliance]

FAQ: Q: Refrigerators do not run 24x7, moron! A: Yes, I know that. But they CAN run at any point around the clock and that is the point. Because they run on and off all day they will obviously require power during times when the solar panel system is not producing energy and will thus require battery power storage. And batteries are not included with most beginner solar kits that people start with, such as the Harbor Freight 100W kit. Q: Refrigerators don't use 600W, moron! A: Not continuously, no. But they can use much higher than that for a split second when the compressor motor kicks on. So a small fridge that only requires 100W when it is running may require 600-1000W to start up and that load may be inductive, which further complicates the requirements on the inverter. Q: Why can't I just look at a power bill for my energy consumption needs? A: Because most power bills do not give enough information to accurately design a solar panel system that can completely offset your energy demand and give you energy independence so you are not beholden to the power company or if you want to go off grid. Q: I don't care about going off grid or energy independence. I only want a net zero power bill! So my power bill is enough. A: That will work perfectly fine... if you account for the net metering purchase and selling rates AND those rates never change. And that isn't going to happen. Public utilities have proven for many years now that they are less and less willing to pay much for excess solar power in cogeneration relationships and they are in complete, unilateral control over that net metering relationship and can change your rates at any time. But in order to properly do the math, which will be complicated, to achieve a $0 net bill for the year you HAVE to know your energy consumption rates at different times of day. And that information is not available on most power bills. Thus, you will need a device that can data log your real world usage for a period of time so you can accurately forecast.

[@kperkins1982]

An hvac system that has parts rated at 30 amps might pull 70 amps for a time during startup. Refrigerator is gonna be the same on a somewhat smaller scale. Giant startup demand to get compressor going, large amount of energy while compressor is running, and then once compressor is off small amount for running fans, lighting etc. It could theoretically run off a 100 watt system if it fed into a battery and every part of that chain was a capable of pushing the absolute max startup compressor amps which while running might be 600 watts but during startup could peak higher for a second. TLDR: Your entire video, meaning yea it's possible but you gotta think it through and plan every step of the way. So while my initial reaction is the same as what you are replying to (um but actually.......) upon thinking about it the point of what you say after rings true, which is that you have to understand all the variables and have planned for them. So I guess what I'm saying is anybody commenting attempting to correct should quit thinking about the compressor vs non compressor wattage and focus on the general message of you should understand your appliances workings while designing a system to make it work how you want

[@LDSreliance]

Thank you! That is exactly the message I am trying to get across, however imperfectly I may have communicated it.

[@HamrickCE]

@@LDSreliance Actually yes, some fridges can use 600w. I have a cheap roper fridge that came with the house and once a day it runs a heater that pulls 400w to melt any ice that built up over the day. I first noticed this a couple years ago when I had a back-up 12v system and we had a power outage most of the day. It had a 210w evergreen panel with a 33Ah battery and I could generate enough power to keep the fridge going (as well as the internet) until that afternoon when that heater turned on.

[@ralphebrandt]

@@kperkins1982 For a refrigerator ONLY I would spec out a 2KW alternator to cover starting loads and 400-500 AH battery with 800 w solar panels. Kenny, you are right on.

[@ralphebrandt]

@@HamrickCE I would probably set up a switch that turns off the heater until it builds up some ice and turn off the ice maker.... These will cause the compressor to run more...

[@enerzise3161]

What we did was start with two batteries and a battery charger and small generator. To learn a little and have something to use for power outages during storms. A year later, we now have an 8 battery bank, 2 generators, 4 inverters, lights, fans, a .98 amp fridge, 1.1 amp freezer and our light bill went from $500 to $600 a month to $70 to $80 a month. We just ordered ten 100 watt panels from Home depot for $109 each. We have two harbor freight 45 watt kits we used for a year. We do not regret buying them. We used coupons and got them for $119 each for learning with. We wanted to DIY this over time and it is going very good. There are great advances in energy efficient technology, and by cutting back here and there, we made great strides so now our energy bill savings is paying for our new panels and laptops.

[@LDSreliance]

Very nice! That is a great success story and definitely the right way to go. I always recommend people start with a small, affordabe solar system (a DIY 10 watt kit would be about $75 if you ordered the components yourself) and play around with it and learn from it before you scale up.

[@rpinpr61]

i live in PR. after hurricane maria in sept. we all lost grid power and water for over 4 months. some here are still out in march!. i got rid of my conventional fridge that burned way too many volts when it cycled daily and got a simple GE $200 top load freezer, added a cheap digital thermostat and set it to chill between 32-37. my smaller solar set up now easily gets me through the night. this style of fridge is dangerous for small kids as they could fall in. but for grownups its super efficient! cold air stays down at the bottom so you don't lose chill like traditional fridges when opened. simply switching to led bulbs, tossing the microwave altogether and being wary of consumption has gotten me through the crazy hard times here in the tropics. if i have major power tool needs i'll bust out the 2000 honda generator...1 gal = 8-10 hrs runtime.

[@Oldcrow77]

Yes but if you do a work sheet where you list your appliances and time used, you get a better idea of your daily usage. Then you have to figure out how much electricity you need to generate to replenish your battery bank daily. Some days you do laundry, dishwasher, vacuum. Some days you don’t. You might watch 3 hrs of TV a night during work week but sports all weekend.

[@Oldcrow77]

Except if you aren’t on the grid you don’t have an electric bill to look at.

[@jessstuart7495]

8. Don't install solar panels over an old roof that will need reshingled within 10 years. 9. Don't install panels in locations where they will be partially shaded by vents, chimneys, or anything else. 10. Allow sufficient air-space underneath the panels to provide good airflow for backside cooling. Don't mount solar panels 1 inch off your roof. 11. Run you clothes washer, clothes dryer, washing-machine, oven, air conditioner, during peak generation hours. 12. The cost of panels keeps dropping, so don't buy premium 25 year panels. But don't buy the ultra-cheap panels either.

[@LDSreliance]

Good thoughts. I agree with all of those.

[@Colaaah]

@Booboobear2388 black soaks heat, white reflects heat...

[@danreid1483]

@Booboobear2388 I would guess that painting the back of any panels would invalidate the warranty. With how low the price of solar is now, it's not worth it. You won't lose that much production because of heat on the underside, especially in Wyoming. It's overkill. You could add 1 more panel which would more than make up for any loss due to heat.

Great video LD, but everyone forgets one of the largest power draining devices. You most likely will not guess it. It is your TV Converter. It uses so much power and it is left on 24/7. Turn it off when you are not watching TV. You will see the savings right away.

[@spencerwilton5831]

Ivor Fernandes a proven myth. They use less than a lightbulb.

[@redsquirrelftw]

Another thing to account for is that the wattage rating is really the wattage you're going to get out of the panel if all the planets align. You should expect about half in average. It's also good to try to oversize the array as best as you are willing to spend because that way even when it's overcast you will still produce some energy. Also you should get a MPPT charge controller and not PWM.

[@LDSreliance]

Those are generally good recommendations. However, for small systems it can be more cost effective to purchase another panel than to upgrade to MPPT. So if you gain 50W of efficiency on a small system for a $90 upgrade in controller is that worth it? What does it cost you to get that extra 50W of production another way? That is the question you should ask yourself.

[@johnf6262]

That's right 1/2

[@davidjames666]

I installed 12 250 watt panels with the 12 grid tied microinverters from Enphase. All this + wires, rails, conduit, cut off switch, etc cost me $5,500. I did it myself 3 years ago. I still have a few years to break even, but in my head, I write it off a long time ago. My electric bill is under $20 a month. I have all LED lights, and energy star appliances etc.

[@LDSreliance]

Nice! That is exactly what I try to tell people. You can do it yourself and you can save a lot of money in the long run. Great job.

[@tzenophile]

@Tony .w LEDs not good for health, LOL. I'd like to see the proper research paper on that one, not paid for by the incandescent or fluorescent industries lol. Anyway, thanks, I will tell this to the people who always complain that I don't have lights on my bike when it's dark.

[@frankbeeckman7575]

​@@tzenophile LEDs that are paired with a transformer give of EMF radiation, a risk factor for cancer. A simple google search will give you a massive amount of research. EMF radiation dramatically decreases with increasing distance. A cheap EMF meter can measure your exposure and determine what distance is safe. I bought a meter because I was in disbelief when I read about this. LEDs also give us an excess of blue light, which affects our melatonin levels, which regulates our sleep cycle. That is not an issue in the morning where we want blue light to wake us up, but using blue light at night will increases our risk of cancer because sleep is essential to rebuild cell damage. In other words, sleep fights cancer. It is therefore prudent to look at the light spectrum of LEDS before you buy them, if you want to use them at night. That is also why our phones and PC's have a night mode with a warm reddish tint, like the color of a setting sun, instead of the bluish light that is abundant in lighting of offices and factories, and daylight where alertness is essential as this creates more profitable employees. This industry is slowly recognizing the danger of blue light and is moving towards "Human Centric Lighting." Not necessarily because they care about our health, but because a healthy employee is more profitable! Conclusion: LEDS can be safe, if you know how to use them. Cell phones are another ballgame. ALL cell phones come with a warning that we should NOT keep the phone against our skull. Why? Because the microwave energy can cause acoustic neuromas and gliomas (malignant tumors) in our brain. Military research from the US & Russia have been warning us since the invention of microwaves (used in radar, 3G, 4G, 5G, microwave ovens, smart meters, etc) for about 70 years! Most research that is sponsored by the telecom industry, claims that "not-ionizing radiation safe is, except for some potential heating." The motive? 5G MUST be applied in the entire world for MASSIVE economic profit! The reality? Gliomas have become the #1 cause of cancer (53%) among children and it is increasing among those who use a cell phone for more than 10 years. "More research is needed", according to the telecom, ignoring the fact that most gliomas occur on the side of the skull where one holds a cell phone! 5G will MASSIVELY increase the microwaves that enters our brain. Conclusion: Financial conflict of interest between scientists and their sponsors and between media and their advertisers, is casting doubt on real dangers. Greta Thunberg started her Fridays for the Future movement, asking the world leaders to just listen to the scientists, but we don't for LOL, because it isn't easy when we have conflicting interests.

[@tzenophile]

@@frankbeeckman7575 Seriously, you sound confused. Give me just one scientific reference for your claims. Or a reference to a scientific paper you wrote yourself, peer-reviewed or not. I already asked for this in my previous post, and you, sadly, are not coming off as someone who knows the science. Or ballpark sane, for that matter. And please don't involve Greta Thunberg. She has science down, you don't.

[@pr0spect4139]

Also something to consider when adding up your service calculation. When adding your heating system or cooling system, only add one or the other. Whichever is the biggest. You will only be using one of those systems at a time so you only need to take the biggest one into account.

[@mydiversions]

Not many of us are aware of the "dirty electricity" that gets generated by the DC to AC inverters that are used to make the solar power usable by our appliances. There are health problems associated with having these high frequency transients radiating from the wiring of the entire house. The house wiring becomes like a radio transmitter antenna.

[@nickdannunzio7683]

Great vid... 1 comment... you can force control your fridge (or any other appliance) and have them "on line" when you want (or need) with very little loss in performance... become the boss of your energy loss... and maximize your inductive load vs resistive load draw on your system...

Yep, no one knows it all. And none of the people with negative comments have been able to come up with anything that was wrong, just a misunderstanding of a fridge running 24/7. I should have said it is plugged in all the time and CAN run at any time, thus requiring battery storage which does not come in any retail kit.

[@jimhofoss9982]

True you need to size your array for your power consumption....but you are being very discouraging....it does work very well with a considerable investment. My farm is off grid. I installed 54 200 watt panels on the south side of my A- frame house. six 80 amp mppt charge controllers for 20 deep cycle 12 volt batteries in parallel. They run two 3000 watt stacked xantrex inverters, for both 110 and 220 volt output. This setup runs day and night, trouble- free, silently, for 10 months out of a year. I have a 8 kw generator for December and January. I need to run the generator for an hour or two daily to charge the batteries during these months. Just not enough charge from the panels during these short days. However, the entire farm is wired, two shops, numerous outbuildings, and two houses. Mid February now, and more than enough power to go around, won't need the generator till next December. Having alot of solar panels will provide enough power generation, even on cloudy days. 25000 invested- but worth every penny. When power off the pole is unavailable this is a great solution. Even my house in town is grid-tied to reduce bills......oh and I live north of sixty in B.C., Canada, so yes it works up north, too, just sweep the snow off your solar panels to keep them working as efficiently as possible. Cheers!

[@LDSreliance]

I'm not trying to be discouraging. I am obviuously a big solar supporter and enthusiast. I just want people to have realistic expectations and understand that it takes a big investment to do big things. Not everyone has 25000 bucks laying around to go completely off grid, although I applaud your system and I am jealous. Someday I will go completely off grid but right now I slog it out in suburbia.

[@leepinnguin9682]

Once the system is on your roof, what would you do if you needed new shingles in say 5 years for some unknown reason? And, if you have a very large lawn, why not put them on the ground on posts if you have the location and no trees or buildings to restrict the panels from sunlight? Thank you for such an informative video.

[@crpth1]

"Put them on the ground on posts". Disadvantages as I see it. One is the obligation to build an additional structure, to support the panels. After all, considering all things equal the roof would already be there! Cable lengths, bury, etc. Can also be an additional issue once more depending on the particular condition. On my rocky ground... On the roof, production and consumption are probably much closer to each other! My personal vision of the issue is simply area lost to the panels. Something that won't happen on the roof. On the other hand when maintenance time (cleaning, etc) comes by. An installation on the ground makes life way easier... ;-)

[@johnf6262]

I put mine on TV tower beside house.

[@spockmcoyissmart961]

Great, practical advice. Thanks for posting! I was approached by a Solar co while in the Orange box store. I asked what is the best I could hope to reduce my electric bill for the area in which I live. He said max 10%. Now, I am in the construction electrical trade so I am not totally ignorant about solar. While working on a home a month ago, I saw the neighbors roof was covered in solar cells, so I chatted with the neighbor about it. When I asked how much his electric bill has been reduced, he said at this point, nothing.....the Solar co installed the cells right away. The POWER COMPANY has not done their part yet, 7 months after installation......I guess the power company is not interested/hurry in losing money to grid tie systems.

[@LDSreliance]

Great comment. Utility companies are in an interesting position with this. I need to do a video on some of this. But basically, they are motivated to decrease peak demand (demand response) because it saves them money on expensive power plants. They would rather have a more level demand curve for power, which is not the real world. Then again they want to make money and have control over their grid system. So they are pretty conflicted with solar and wind.

[@gosolxsolar]

LDSreliance if the power company hasn't done their thing after 7 months, it usually means the installer didn't do something right and the power company is waiting till the error gets fixed.

[@notreddit1701]

Stephen Anderson not necessarily. The local inspectors for the county or city will fail the job however the utilities can take up to nine months just to come out for the first time. If it passes the local inspection there's no reason that it would ever fail the utility inspection. I work for that solar company in the big orange box store and deal with this every day

[@gosolxsolar]

Will Gawlik I guess it all depends on which utility it is. 7 months would be unthinkable in the Seattle area. Here it is very possible to pass electrical inspection just to have the utility show up with the meters and say, "hey, that meter socket is too high, or that's a CT can and needs a variance, or you need a knife switch on the disconnect."

[@spockmcoyissmart961]

I would like to add, in my area, a contractor must contact the power company and describe the work in order to get a 'work order number'. Then the work is performed. Then the inspection by a 3rd party, UL inspection agency.. The inspector is given the work order from the contractor. Upon passing, the inspector gives the work order number back to the power company to confirm the job has gone full circle and is good to go.

[@MikinessAnalog]

I would also add if your biggest fear is power outages, NEVER go "Grid-Tie" because if the grid goes down, so do you. I went off grid to be isolated from outages (not necessarily to be "green"). Either get solar for battery back-up or go off grid entirely. (Off grid = approximately 5-9 years of electric bills up front. That is the cost)

[@josepeixoto3384]

i wonder what that means, *5-9 years of electric bills up front* ; how is that?!

[@MikinessAnalog]

@@josepeixoto3384 the average cost of being completely electrically isolated from outages. - What ever your electric prices are in your current location (home, city, nation).

[@rp9674]

I partially agree, I think if you have a battery backup you can still use it during a power outage. An off-grid system is probably much cheaper and easier to DIY, especially if you could put it on a patio awning or a gazebo instead of roof of the house.

[@samdp8497]

You're partially correct. I have a Sol Ark 12k grid tied inverter with 30kWh battery back up that runs my house during off solar hours. The Sol Ark can utilize the grid if needed, sell excess power to the grid and even sell excess battery storage to the grid. I wired my solar power into a separate panel box and moved circuits to that box - utility, lighting, refrigeration, HVAC and well pump. I still have the grid available if I need it. I'm waiting to get through this winter to see how the system 'actually' performs through the winter.

[@conmcgrath7174]

I am impressed, let me just say that first. When I saw the title, I was all ready to tear whatever you said 'to pieces' but no, there is nothing you said that any rational person might disagree with. Ok, you didn't address battery banks or germanium diodes but it wasn't entirely the remit and I do appreciate that? You might get the impression that I am indeed an 'expert' and yes, I've spent over 30 years installing 'back-up' systems for buoys, beacons and light-houses. Everything from diesel generators to wind gen's and of course, Solar Panels. For those that know, you have to change the math for installations in the water? I might explain that or just leave you to think about it? The reason I don't explain is because I respect you and would hope and expect that you might figure it out all by yourself? I absolutely love your question and answer 'section', getting the impression you were getting PO'd with stupid replies. Hopefully you won't see mine as such, I certainly don't wish it to be.

[@LDSreliance]

Thanks! There are many irrational people out there that love to argue over silly points and this video attracted quite a few of them as you can see by the comments and the FAQ.

[@MrStefGamble]

Good video LDSr. All makes sense. Something like dodgy deals I know nothing about so I shall not comment on, but I would like to add a few points from my experience. Item 1. It does not matter really if the panel is producing a tiny positive current outside prime sun hours as long as it IS a plus current. Even a trick will run a single LED light. 2. The best power consumption measurement system is a controller or monitor that shows current (pun intended) usage in amps, overall battery voltage and general reserves. My RV has a B12 Battery Monitor that does this job which shows when power draw is exceeding power production, so I can turn off devices as the sun declines. 3. Pre set-up device choices are critical. All lights must be replaced with LEDs which come in 'day light' and softer 'warm light', so you can have separate work and relaxation Ares. They come on immediately and run comparatively safely very cool so safe to touch, last like forever so what's NOT to like about them. 12 V DC TVs and computers etc are commonplace and every time you convert a voltage you lose about half of it's power via the transformation (transformer) process, so choose devices that use the same voltage as your production system with GOOD HD multi core cable. A good PURE sign wave invertor will take care of unavoidable 120V or 240V AC needs. 4. Expectations. I find that judicious (word of the month) use of the right appliance at the right time will get the best out of any solar power system. For instance use cooling devices like fans and cool boxes when the sun is at its hottest and pouring out more energy than your batteries can store. A cool box is insulated and will will keep its contents chilled, or coolier, if you like. Heat in its natural absorbed form on bricks etc CAN be stored via many systems for gradual release over night. That is just a cool box principle in reverse. 5. Installation Placement. I have installed a secondary independent system in my RV where the panel is NOT fixed but attached to the system by 5 Metre HAD lead and plug whereby I can move it around my bus three times on an average day. Set it up at night for next day's rising sun, move pre noon, move afternoon, and repeat set up again at night. I get every erg on offer and the exercise is good for me. Obviously the above may not apply in a non RV set up. 6. Dodgy deals. Something you have taught me about. Thanks. Peace. .

[@LDSreliance]

Good points. I agree with most of that. It is nice to hear from another RV dweller using solar. There are a few of you subscribed here and I enjoy hearing about your adventures. If I wasn't married and had kids I would probably be doing the same.

I use the 45 watt with 2 deep cycle marine batteries to power my computer, modem, satellite dish, printer, a couple of LED lights & charge my cell phone. Its been a year now with absolutely no issues. I will add to it this year adding both panels & batteries to get my TV, more lights &/ or with any luck my fridge on solar. Don't forget the huge inverter needed for refrigeration.

[@LDSreliance]

Have realistic expectations is the key part of what you said. I always encourage people to start out small and scale up later. But don't buy a kit and expect to run your air conditioner or fridge with it.

[@PatricksDIY]

Finally I came across a video where the person knows what he is talking about, been getting so annoyed with the people saying " Solar panels suck, the 200 watt Harbor freight panels I bought wont power my 300 Computer" lol Great job!

[@Geistie1337]

a fridge isn't consuming 24hours a day the maximum electricity.... the pump is turning on only when needed. lets say 2 hours a day its working "full mode" depending on isulation and usage ... blabla

[@TheAllMightyGodofCod]

I agree. And newer inverter type refrigerators keep the compressor running all the time but use far less electricity and never fun at full power. Plus, as i said in my comment, 600W for a refrigerator is insane!

[@darkshadowsx5949]

I dont think anything household product consumes full power 24/7. unless you leave a light or bathroom fan on and forget about it. its a good idea to buy watt-meter to grasp the real time usage of a single device and not trust the manufacturers numbers.

[@a64738]

My frigde and huge freezer used 70w on average during summer combined (only thing in the house using power and that was what the power meter said)... But they say a frigde uses about 1500w when starting and that has to be considered when using a generator or inverter.

[@starfishgurl1984]

Thanks for this awesome video! I’m preparing to build my own tiny house and buy the land to park it on and I want to use solar for my power but know nothing about it really so I want to make sure I get it right. I live in New England and the piece of land I’m looking to buy is located in an area prone to weather related power outages in the winter do to the power company being so big that it often takes time for them to get to that area so it would be nice to never have to worry about that by having solar to rely on instead!

[@LDSreliance]

That is a great use for solar. Just keep in mind it has some limitations and do your homework and you will be fine!

[@tonybrock5288]

If you actually have a 600W fridge you need to bin it now. It also does not run continuously 24/7. It may be 12/7 on average at the most. Most fridges will be less than 100W and if not you need to change your fridge now!

You missed the point completely.

[@johndias6614]

Thanks for the good video. Good information. I started with an engineered solar well system from RPS solar pumps. 400 watts and 48v battery bank. There's a learning curve and this has shown me what to do and not do. The smoke from the California fires (September 2020) has reduced the rate of charge. I had to use an automotive battery charger to give the batteries a boost.

Wow, that is nuts. It seems like California has these fires every year. Do they affect solar every year?

[@KG5RK]

One concern I would like to raise about Solar installations is the roofing materials that the panels are mounted on. (assuming a roof installation). I was looking at all the framing infrastructure used in a typical multi-panel installation, and was quite uncomfortable. I realized that at some point AFTER the solar plant was in operation, the shingle roof would EVENTUALLY need to be replaced. That makes for some SERIOUS extra work & expenses!. I think it makes more sense to install a wind turbine(or 3) rather than buying solar panels. I suppose it really comes down to return on investment, and where you live. For me, WIND & SOLAR are great choices here in Texas, especially WIND... What do most people do in these situations?

[@LDSreliance]

You are correct. Solar leasing companies don't really tell you all that will be involved if and when you have to replace your roof. It is in the contract but not usually discussed. Solar leases are usually for at least 20 years and that is about the lifespan of a roof, too. And in Texas/Oklahoma you are bound to have hail damage or high wind damage at some point in 20 years, too. Most agreements I have seen will charge between $500-1000 to have a team come out and uninstall the solar panels and then reinstall them after the roof is replaced.

[@LDSreliance]

IMO, the best way to power a home is a hybrid setup with either micro hydro or wind and then combined with solar panels. And I would rather mount the solar panels on a back yard rack system than on the roof for multiple reasons.. if you have the room of course.

[@KG5RK]

LDSreliance: Thank you very much, I do like the hybrid idea best of all. The Sun doesn't shine all the time, but the wind blows MOST of the time...

[@gosolxsolar]

John Mulhall ground mount systems are much more expensive than roof mount unless you do a dual axis tracking. Roofs under solar last far longer than roofs not covered by solar since uv rays don't touch them.

[@akadog6319]

I have a small system for emergencies. To run a freezer long enough to keep it frozen. To monitor news, operate a radio, small TV, or a light where I will be sitting. I can run a water pump for a short period of time and manually maintain a tank level.

[@r.b.l.5841]

I suggest anyone interested in a system, start with their utility bill, it will tell you your typical monthly consumption for each season. Next get a decent amp meter and a P3 Kil-O-Watt meter. The amp meter can tell you not only the amperage (power) something like a furnace fan motor is using, but also (and often more importantly) the peak In-Rush Current of starting that motor from a dead stop stand-still. My furnace fan as an example uses 5 Amps 120 volt (600 watts) running steady, BUT starting from a dead stop, it has for a few seconds an inrush amperage of 12 Amps. This is imporantant to know and understand. The P3 Kil-O-Watt meter plugs into a standard wall outlet, then you plug into it an appliance - say your 40 inch side by side fridge. Let it run a day or so. Then check the meter, it will tell you how many watts were used during those hours it ran. My fridge uses about 600 watts running, uses 1300 watts per 24 hours on average, and by checking with the Amp-meter I also know to start the fridge compressor the in -rush is 6.4 amps but only for about two or three seconds. Make a spreadsheet of all the loads, what they need to start, run, operate for 24 hours. Highlight the ones that are critical, that you need 'no matter what' like a furnace fan or fridge. As LDS says, look at what can be reduced in power - LED lights, smaller or more efficient appliances, etc then start planning what it will take to run things, collect that power and store it (if you store it).

[@homomorphic]

Actually, while south facing makes sense from a purely electrical production POV the compensation for production under different metering schemes can alter this. For example, I have NEM 1.0 in California and it provides TOU compensation for both consumption and production. Since the peak cost period is during the late afternoon, I have west facing panels which while they generate less power during the day, their effective production (i.e. their financial production) is doubled for the time at which they are optimally aligned with the sun (in the late afternoon). Thus, they produce nearly the same financial production as my south facing panels.

[@FalkinerTim]

Yes, that is a good point. If you have a north/south ridge on the roof, putting solar panels facing east and west can give you a slightly lower total but a better spread through the day.

[@bagmszsolarenerji4029]

If you have battery system you can store more production from south and use it afternoon however that's interesting approach

Home Refrigerators and Freezers have a 50% duty cycle with the door closed (and the Ice maker in standby=bin full), not 24Hours. I Measured (graphed). What varies is the cycles duration. ~15min for the freezer I tested and ~6 min for the refer. Sill heaters draw a small bit. Defrost recovery about 3x normal run.

[@LDSreliance]

Yes, that is correct. And that cycle occurs 24 hours per day. Thus the point is that the device will run LONG after the sun goes down and will require a battery because the solar panel kit that you bought from Harbor Freight will be useless for 2/3 of the day.

[@caroledavis9362]

We live in N AZ, and have a 8.5Kwh hybrid sysyem. This is 30 panels (split between the East facing and West facing sides of the roof) with 24 second hand batteries and one inverter (33 Amps). We run everything in the house on solar, EXCEPT the large Amp items (dryer, A/C - heat, stove)... We are on a program with APS where we bank the excess watts, then, as we are on the standard pricing bracket, we get to use those banked watts at any time (if you are on one of the off peak programs, the power co only let's you use the banked watts at the same time as when they were produced - so if max production is at 11am - you would only be able to draw those watts at 11am - by remaining in standard we can draw those watts at night). We run the house A/C for around 1-2 hours in the late afternoon (it was 103 recently and the house was 80 - we cooled it to 75 then turned the A/C off), then use the portable A/C only for night time. This seems to work very well - our last two electric bills were $20 and a few cents. Our highest bill previously was $325. (Average was 175 - 225) Should the power company go away for whatever reason, we have the portable A/C, a plug in turkey oven and a two ring plug in electric 'stove top' and a clothes line outside as substitutes for the large Amp items. So far we have used a max of 30% of our battery storage in one 24 hour period - but managed to recharge before the evening again - despite cloud and forest fire smoke obscuring the sun. The batteries require periodic equalizing to maintain the string output. Otherwise it is pretty much maintenance free.

Good vid. I would suggest that installers use a rail system that only attaches under the eave (uses horseshoe shape to go from top to under eave) thus eliminating nail or screw holes in the roof which inevitably result in future leaks and expensive repair and require uninstalling panels to get to the roof leaks.

[@serg3y]

4:14 I disagree. I would say splitting the panels East and West can be as good and even better in some cases! If you have an east west roof I would put panels on both sides, more on the sunset if possible, if you use more power in evening. And I would put a total of 40-50% more panels then the inverter maximum capacity. This is fine for an inverters so long as you don't reach MaxV. In practice with an east-west arrangement you will still only rarely reach the inverter maximum capacity. What it give you is a lot more power generation spread evenly over the duration of the day, and more opportunity to use it rather then sell it. Also it only costs a fraction more because you keep the same inverter and only paying for more panels and a bit more for installation. Alternatively a SouthEast and SouthWest split is also very good (northern hemisphere), its halfway a south facing roof (maximum production per panel but generation maximum at midday) and east west roof (described above). So if you think your roof is not optimal because it is not south facing (northern hemisphere) then think again. You also forgot to mention that even for a south facing system it is still a very good idea to use 20-30% more panels then the inverter maximum capacity, because the system will only rarely get to its maximum and this is a good way to optimize the system. Also having a higher pitch roof then the latitude can be good if you are doing the east west split( because the sun is lower) or if you want to optimize for winter generation rather then summer, because that is when you spend more on heating.

[@JJ-zg1hh]

Sergey K I'm glad you posted that comment because I have an East West roof and I was worried that solar panels would be incompatible with my house. Everyone seems to say that the roof must be south facing but when I look at how the light falls on my roof if I put panels on both sides it looks like I will generate more power than on a south facing roof alone. I think this 'south only' argument is putting a lot of people off solar when it's not entirely true.

[@serg3y]

@Jan van Coppenhagen true if you want max wh per metre of panel. But if no one is home middle of day then you sell it for peanuts. Panels are cheap these days compared to cost of install and inverter. So max wh per metre of panel should not be driving system design.

Refrigerator running 24 hours? There's something wrong with it then.

You have 7 sun ours, 1/3 of the day, and your refrigerator doesn't even run a tenth of a day.

A refrigerator doesn't care whether your heater is running or not. It does approximately the same amount of work summer or winter because you're keeping the indoor temperature of your house approximately the same summer or winter.

[@mosichat]

Great video! I’m starting on my journey to becoming certified.

[@holdon4992]

Ah, good advice. I bought some portable solar panels and a power station to experiment. Everything I see in this video is spot on. I’m learning a lot from the small system I bought. First is placement and angle of solar panels to maximize input, which involves a lot a panel movements as the day and sun moves, so must the panels. For a home system where the panels will be static, it takes a lot to understand the sun hours concept. Also, the difference between a sunny day to a cloudy one is huge I have found. I have yet to achieve maximum output from the panels I thought would be achievable so, lessons learned. I have ordered a single solar panel from a different manufacturer and different solar type (fixed vs flexible) to continue my experience. So, after charging the power station, testing becomes the focus. Then you need to consider Watts available AND watt hours. Watts tells you what you can use (fridge, tv, coffee maker) while watt hours tells you how long you can run these things. In one test, for example, my very old but apparently very energy efficient refrigerator runs in 20 minute cycles where it uses about 200w. Since it is not continuous, on a 1000W power station, it only used 10% of the charge in an hour. Theoretically, I could run it for 10 hours but I would probably expect maybe 8 hours before the power station ran out of juice. Right now I am testing all the various appliances in my home and it’s getting easier to determine what to expect with a little math and knowing the voltage and amps a device requires to see if the power station can handle it and for how long. My vacuum takes about 800W so I expect my test power station could possibly run it for an hour. Not that I need that amount of time to vacuum but it a good test measurement. The power station I have has a short lived overwattage up to 2000W which is unusual for portable power stations. What happens is the power station will run for a minute or two at a higher wattage (above 1000W) before it shuts down. The simple test was an electric heater. It requires about 1209W continuously so the power station shut down after a couple of minutes. Curiously, my coffee maker went to about 1150W for almost 2 minutes but then dropped to about 700W and the power station did not shut down. So, I can make a cup of coffee. I need to test a few more times to see if this is a reliable source of power for this appliance. So, learning about expectations and needs is important! If you a relatively small amount of money, that is, a small percentage of the cost of a full home solar power system, I would recommend experimenting like this as well. You’ll learn a lot quickly and be able to determine the best course for a home solar system, what type, how much power your household really requires, etc. I’m not there yet myself but it’s giving me a very good idea of how this whole solar power system will work and determine the costs and value. In the meantime, I have emergency power now for whenever power goes out, at least for a short time. And, depending on the weather and length of power outage, recharging to run again.

[@LDSreliance]

Great advice. Thanks for sharing your experiences. I try to drill all of these concepts in so that people have realistic expectations and don't sour on solar.

Solar cost per KWh will never be close to coal, oil, gas, hydro, or nuclear. But,,, if you like to fiddle with tech or be different, simply send all your power into the grid and take the reduced electric bill. Don't fiddle with batteries. If you need uninterrupted power, just buy a generator for outages. Over 20 years, batteries will cost a lot more than the panels and inverter.

[@grinddelosmontes9444]

[@jamesmarchitto7040]

My advise to all is to do your research, educate yourself as much as you can about how solar works. ( PANELS on a north or east facing roof will NOT benefit you. ) When you get a representative that comes to do an evaluation of your home you can tell if they know what they are talking about. Also read the fine print of any contract before you sign it TAKE your time and READ it !!! Do not sign unless you are comfortable and you KNOW it is going to benefit you for the next 20-30 years. Sizing a system to 110% of your consumption is a good rule of thumb. Some states will only allow a system to offset 95% of your use. Also the Federal Solar TAX CREDIT is not a refund, it is only applicable IF you have a tax liability, meaning you OWE the IRS money. IF not this is something that you can not factor into the reduced cost of a solar system. I have been a solar advocate since 1974 and am happy to advise people looking into going GREEN !!!

Not true about the east side / west side. at lower angles than 30 degrees these two sides are only marginally less productive than south facing low angles. East is also better than west because of the lower morning temperatures in summer

[@deedemarest443]

I was told by a solar guy that west is actually now being considered better than south. Shade does lower temps to some degree but in the desert all directions are hot and absorbed by the panels. As I understand it, solar does not need the sun beating directly on the panels, it needs peak day light exposure from the sun (when the suns energy rays is closest to earth and is of course based on your positioning).

[@zzzerlv]

[@LDSreliance]

Try unplugging your refrigerator when it is "off" and see what happens. It is still consuming power, even if the compressor is not running. And either way, the point was that the device CAN run at any time 24x7.

I'm going to start with a simple project - 10 Watt Solar Panel into a Charge Controller hooked to a battery, and then into a fan to 12V fan to keep air circulating in my shed. I had no idea where to start, until I watched this series. Now I have a plan and simple project to get started. THANK YOU!!!

3:36 If your refrigerator is RUNNING 24 hours per day, it's definitely time for a new fridge!

[@LDSreliance]

Do you unplug it when you go to bed? It runs off and on around the clock. That is the point. If you buy a solar panel system to try to run your fridge you will need a much larger battery storage component than if it was for your landscape lights or entertainment center because those loads are not used around the clock.

The real task is figuring out how to produce solar panels with higher efficiency. The sun puts out astronomical amounts of energy, we just need to figure out a more efficient way to harvest it. Even with modern solar panels, they will last long enough to get your money back in the long run so it's worth it. Most people don't have the money it takes to put together a system that covers ALL your energy needs, which is where the shady solar panel salesmen come in. Don't get into any contract, most of them are something like 20 years... are they out of their minds? It is possible to start with a fraction of the "end system" you want. Buy the components you'll need in the end and continue to add panels as you save and can purchase more. The truth is that the "powers that be" don't want you using solar or anything renewable. They want you broke and tied down by all your bills and burdens of life. I don't know if borrowing money through a personal loan to build a system would be wise either. The system WILL pay for itself over time for the initial cost, but with interest, fees, etc. it's probably not efficient mathematically/financially.

[@ddd228]

My system will be a TEN year pay back . I'm in 2 K,so far. 5 12 V. batteries and (5) 150 watt panels,MPPT controller and a 1,500 W. inverter. imgur.com/CdlI4c3

[@PlanktoniusRex]

I disagree. Space is cheap and new technology is expensive...just buy more standard panels. If you need more power, buy more panels. If your HOA wont allow it then move.

[@danielpeterson6987]

My soler faces in one place and my batterys are changed by 10 AM. and in the winter it is changed by 11:30 AM. And in cloudy day's it takes to change by about 3:30 AM. in the winter and the same in the summer.

[@emperorinsaino]

Good points, thanks. I didn't mind that my array wasn't enough to power consumption, the idea was more to implement a basic system that almost anyone could afford, and see what its capabilities are. This way people can look at my stats online, and know what to expect for the money I paid.

[@LDSreliance]

That is a very valid way to do it. So you are getting good returns?

[@Myhomeentertainmentsystem]

I am one of the very few people who got all my 5600 watts of panels and inverters for free after the 30% tax deduction, becausei owed a lot of back taxes, 3 dollars a watt for installition ,panels a hair less than 4000$ inverters 2500$ , I installed myself .30% of16800$ is what I owed.my panels were free because of what I owed,this was a accident, learn from it!

[@ramonacatterton3753]

Can you explain a bit more on how your panels were free?

[@dharmasawyer7775]

they're not free. the discount is no more than 30% plus whatever your state tax gives back

[@deedemarest443]

If you lied on your taxes on the full cost of the system to included installation, you might.

[@JonathanWelle]

Right. What this person did was take the retail cost of a purchased system with someone else being paid for the work and applied it to his own labor.

I think it is best, NOT TO INSTALL SOLAR PANELS ON THE ROOFTOP. IF, you have land, use a ground installation.

[@LDSreliance]

Sure, if you have the land I will agree with you. I don't think most people do in suburban America.

[@Noniksleft]

what are the main reasons?

[@cliffordtmitchem-crewswfls7673]

Ground mounting is significantly more costly and rooftop solar utilizes unused space.

[@LDSreliance]

I agree. I think roof mounting for most people who don't have an acre of land is the best option and cheapest.

[@CRsolar]

I agree but if you have a rooftop - that isn't a unwalkable pitch and a good quality roof - the money you save helps justify the cost to even install a solar project or not. most people cant seem to afford the cheapest simple install. or they just don't realize they pay non stop for electricity.

[@kalhoon]

one thing alot of guys do when they sell you a deal on solar panels but don't tell you , you need batteries to go with that. a bare system i run in the shed to charge tools runs one battery. but needs 4 (1000 cca napa cheapest @$100 each) or more to run anything overnight. like a mini fridge

[@tomcurran1538]

Good points. About temps: portable solar generators usually don't work below 32F or over 105F. On the point of unreasonable expectations, I've seen people move to northern Vermont from PA, NY, CT, etc., and somehow think they can run a household on solar...even the heat! Guess what, it is cloudy up there and it gets dark after 4 pm in the winter. The problem down here in NC is cooling and dehumidification. This can be done with solar using a split unit, good insulation, and realistic expectations.

[@LDSreliance]

Very true. Thanks for watching!

[@q-_-p.d-_-b]

If solar panels are designed to run cool... whats going to happen to solar shingles?

[@LDSreliance]

Too new to really know. From what I read earlier types required special plywood accomodations for cooling but it sounds like they might have fixed that.

[@Jake0Miller]

The same thing that happens to solar panels... when it's really hot, they're a little bit less efficient.

[@davidbeppler3032]

Solar shingles have passive cooling. Think of the reduced electric bill to cool a house that does not have a super hot roof in the middle of the day. ;)

[@vidadvocate9522]

[@svedjenaeva]

Some good things to think about. But a panel does not "need" to be facing South, nor have a certain angle. By doing a calculation (there are free programs and web sites) you can see how good it works. I have engineered pv systems facing more or less West, with 10 degree tilt that generates 850 kWh/kWp/year

[@MrTubeman123456]

Very helpful I worked for yrs in electrical but never with solar I would have a tendency to think that more would be better now I'm going with used panels and the right type of equipment not necessarily the best stuff I'll just have to see what happens but video is very helpful thanks.

[@notyoung]

Excellent place for newbies and wannabees to start! If someone wants to power an appliance with solar power, they need to first spend $20 on a Kill-A-Watt or equivalent and learn how much power that appliance uses in a week. Our Samsung fridge/freezer averaged 59 watts/hour over a 15 day run, but the actual power varied from 4.1 watts (one small circulating fan running) to 560 watts (both defrosters on - it has separate evaporators for the fridge and freezer compartments). They also need to check the historical weather data for their location to know not only the daily useful sun hours but also the mix of sunny versus cloudy, rainy or snowy days. At the moment, I have a laptop (average power over 24 hours is 13 watts/hour) monitoring my small solar installation. This week's patchy sun and clouds mean that I need 500 watts of solar panels connected to keep up with 24 hours of laptop use (312 watt hours) although the insolation charts say something like 4.5 hours/day of useful sun, which in the best case could be interpreted as saying that one 100 watt panel could handle the load. Those useful sun hours numbers are averages but long term solar design should be for the worst case with maximum load and minimum sun. My system has a 12 volt, 540AH battery bank (six 90AH AGM's, used but test as new for $35 each), two 250 watt panels (also from Craig's List @ $150 each), four 100 watt panels, two 30 amp MPPT controllers (EPEver Tracer 3210a, sureelectronics, ebay). two 2000 watt pure sine wave inverters (ReliablePower, ebay). I'm still tweaking the system and the amount of solar power online varies from week to week. 900 watts can recharge 12 hours usage in one sunny day in winter or summer - patchy sun like this week would require several days for a recharge. My initial goal was a "Wait until daylight" solar generator that would provide essential power (fridge, lights, phone, internet) during a commercial outage at least long enough to avoid setting up a gasoline generator in the dark or during a thunderstorm. Depending on whether the central heat is needed, the "solar generator" can provide power for between 10 and 26 hours - definitely enough hours to "Wait until daylight".

[@LDSreliance]

Yes, I have said the same many times on my videos. Get a Kill A Watt or other power meter to find the real world consumption first. Don't just look at your monthly power bill. And make power conserving upgrades before going solar. You will save a ton on your solar installation by simply changing all your bulbs to LED. But other upgrades can be just as huge.

[@ddd228]

KILL A WATT devices are GREAT! I have 5.

[@warren52nz]

Good advice. Many people don't seem to realise how long it takes to get your money back on a solar system when grid power is cheap. If you're using batteries instead of grid tie those batteries need to be replaced from time to time and the cost of a bank of batteries buys a lot of grid power!

[@LDSreliance]

Yes that is true. Good comment.

[@warren52nz]

@@LDSreliance I guess the downside of a grid tie system (without batteries) is that your system feeds energy into the grid when demand is low so the power company still has to be able to handle peak demand when the Sun goes down. So they can't downsize which I suppose is the ultimate goal. If you have batteries to power your home overnight then they get charged during the day when demand is low and you unload the grid in the evenings when grid demand is high. I don't know... I think really good, cheap storage is the end game here.

[@LDSreliance]

Peak demand never happens when the sun goes down. Peak demand is on the hottest day of the year in the summer. That is the day they have to plan their generation around. Whatever they can do to decrease that one day each year they will spend almost any amount of money to do it because it will be cheaper than building more power generation plants.

[@warren52nz]

@@LDSreliance Yes that makes sense. I didn't look it up but thought I'd read elsewhere that evenings were higher demand because that's when everyone is cooking. But yeah in a warm climate (only) air conditioning in the afternoon would be the highest demand. It doesn't get stinking hot everywhere in the world. Here in New Zealand a hot summer day is 27°.

Matthew 26 KJV: The Plot to Kill Jesus And it came to pass, when Jesus had finished all these sayings, he said unto his disciples, 2Ye know that after two days is the feast of the passover, and the Son of man is betrayed to be crucified. 3Then assembled together the chief priests, and the scribes, and the elders of the people, unto the palace of the high priest, who was called Caiaphas, 4And consulted that they might take Jesus by subtilty, and kill him. 5But they said, Not on the feast day, lest there be an uproar among the people. Jesus Anointed at Bethany: 6Now when Jesus was in Bethany, in the house of Simon the leper, 7There came unto him a woman having an alabaster box of very precious ointment, and poured it on his head, as he sat at meat. 8But when his disciples saw it, they had indignation, saying, To what purpose is this waste? 9For this ointment might have been sold for much, and given to the poor. 10When Jesus understood it, he said unto them, Why trouble ye the woman? for she hath wrought a good work upon me. 11For ye have the poor always with you; but me ye have not always. 12For in that she hath poured this ointment on my body, she did it for my burial. 13Verily I say unto you, Wheresoever this gospel shall be preached in the whole world, there shall also this, that this woman hath done, be told for a memorial of her.

[@meamenopatemoshelawillem4874]

I read all this looking for solar power

[@KrK-EST]

@LDSreliance I do not know what you do with your fridge but here/mine it is rated 300W and it realisticly takes 350w, and it only works 5 to 20 minutes in a hour (depends is it summer or winter and how often you open the door). But yes deep fridges are one of the most consuming for solar systems. For a fridge like mine you need 3x 400watt panels for 24h powersuply (overkill but if there's no sun for a week it will still have power). I always have backups, so if you have solar do get atleast a small wind geny too. The higer and bigger the more power you will get. 1 windmill can go up to 10kilowatt, aka small powerplant scale. So a lot of flexibility on what you need and what you can get, but windmills are more expencive if you do not just get the micro(the simplest) one and get the pole yourself. The cheapest atm is still going solar. Hope the wind catches up soon.

[@JD-rp1fx]

I used the supplied mounting clips to attach a Renogy 100w panel to the roof. I notice now that leaves and pine needles collect under the panel. Next panel I would set up a rail to hold the panels at least 2 inches off the roof shingles.

[@LDSreliance]

Renogy mostly sells to people using them for temporary off grid usage. So they only include the hardware most people are going to use for temporary usage, like for boondocking in an RV. I'd recommend using Z brackets and, like you said, mounting the panels at least a few inches off the roof. The leaves and stuff are a secondary concern. Airflow underneath the panel to keep it as cool as possible is the much more critical concern.
