One of the panel arrays is pointed West so it continues producing until 5 or 6 pm.

Its very comfortable not having to worry about the power company or grid failures that seem to be getting worse.

Look at it this way, if a solar system installed at your house has a 8-year simple payback, and a new water heater has a 2-year payback, which one is a better investment? With no other information, you have no way of knowing. How about adding a third alternative: Does it makes sense to add a PV system and a new water heater?

Short question: can you share your build specs? How many panels of what wattage each? What controller do you use, what is your setup for energy storage? What model batteries and their Kilowat/ Amp hour capacity? Any other details to share? My situation: I live in Miami, Florida, USA. I think we have comparable sun levels to Australia. I've been on the fence for a while deciding whether to take the expensive plunge into a full conversion. One issue is the buyback- our electric provider (FPL) doesn't buy back excess power (yet) so we either have to store excess power in batteries or lose it. Factoring that loss of potential income, the break even point on a solar system ranges from 12-18 years (range is due to varied cost of our battery choices and how energy capacity storage we want.)

[@pholliez]

Hi Sam! Thank you for sharing. I’m in NSW, did you have to get any special approvals for a non-solar company to do the install? We’ve been told by a few different sources that this isn’t possible and/or our home insurance will be invalidated.

I found that by delaying the charging of my DC coupled battery until noon in summer, my output increased by 12%. I also found that my 41 panels rated at 13.25 kW could actually produce 15 kW of power. This 15 kW limit was made up of 5 kW going straight from the panel's DC output to my DC coupled battery battery and 10 kW flowing through my 10 kW inverter to my EV, house and the grid.

Another great advantage in hot climates is they shade the roof and make cooling the house more efficient just by their presence

This is actually why I want it. My roof gets direct sunlight and heats my attic to unbearable levels 😥

[@bwwilson1765]

@David Golden Never thought about that aspect. Interesting thought.

[@djdickey]

This largely depends on how much space you have between the panel and your roof. Tesla tiles sit directly on the roof. There are even water cooled panels to make the panels more efficient in hot climates. These double as water heaters for pools and assistance to your regular water heater.

[@geroldmanders9742]

Panels will provide a bit of shade, that much is true. But in hot climates those panels heat up. And not by a little bit either. This excessive heat reduces the lifespan of the panel pretty drastically and to add insult to injury, the efficiency of turning sunlight into electricity drops a lot as well. Planks would have a similar effect regarding shade, but are way less expensive than solar panels. Shade helps in areas with high temperatures, but what you really want is mass. As in 1 meter thick walls etc. The sun will heat such walls during the day but the inside of these walls remains cool. And when the temperature drops at night, these walls radiate the heat back out, so you will feel comfortably warm. Of course, the sun will "charge" these massive walls again during the day and you will be comfortably cool during the day. Costs more during construction, but afterwards you won't need any airconditioning at all. The energy savings over the lifespan from such a house easily cover the extra construction costs.

[@davidgolden6068]

@@geroldmanders9742 meter thick walls??? Man, that sounds preventatively expensive, even considering a lot of energy savings. I've never in my life heard of a house being built even similarly to that.

Here in Australia we have two factors in favour of solar, the first is we get a lot of sun (perhaps the only advantage of being on the driest inhabited continent) and secondly we have much cheaper solar systems. I recently added a 6.6kw system to the already existing 5kw system and added two Tesla Powerwalls. The system powers my house, charges my Tesla and exports about 150% of power I use even though the system is throttled by my energy supplier to 5kw of export. It takes a couple of really low production days for us to draw from the grid - happens about once a month on average…

[@stiaininbeglan3844]

Which is exactly why people in wetter (but still sunny) climates need to consider options other than just solar. I've seen so many videos or comments in which people say things like, "But solar doesn't make enough power!" And solar is the only thing they're trying or wanting to use. But wind and hydro also generate electricity easily and aren't hard to install. And these people don't have to go with only one or the other, but often pretend that they do. When I install my grid, it will utilize all three, as all three are a thing where I live and plan to live. It might take a while, but there is zero reason to be a purist when there're other options available.

[@carllennen3520]

@@stiaininbeglan3844 It isnt about being a "purist, its about practicality and feasibility. Hydro power is not only rare for anyone to have access to moving water, but the components are seriously expensive, if you arent jerry rigging something yourself out of an old washing machine. Wind is also cost prohibitive. You cant generate any real usable power through wind, unless you have an enormous blade head, with an enormous generator coupled to that enormous blade head. You either have no clue what you are talking about, or are so rich, the costs wouldnt affect you. Most people do not have river frontage on their land, or the capital to buy land with river frontage. And even if you did, the river would have to move fast enough and consistantly enough to generate power, and even then, you are fighting with the Government to allow you to build a water wheel to generate that power. People arent poopooing wind and hydro. Its just not feasable for the vast majority of people.

Not necessarily. Batteries are far more expensive than solar panels in terms of life cycle cost when used continuously. They are only good for so many charge/discharge cycles. Do the math on the cost of each KWH of charge/discharge vs what you are saving on your power bill. You may actually be spending more. You will likely be replacing your batteries every couple of years this way and need several thousand dollars worth depending on your energy consumption.

But it became very handy when ib 2012 we were hit with Sandy hurricane and our neighborhood was left with no electricity for a full 2 days. I remember when I was getting home when it was already dark and turning on my lights in living room I did hear how people taking a walk outside (what else to do when there is no electricity in your house) were whispering "how does he have electricity at home?" :) that was the best moment.

I retired a couple of years ago so I can make use of the electricity generated as its produced - mowing the lawn, charging batteries, etc, etc. If your system is below a certain level it is metered for what is produced but they just estimate the amount that you use of that production, so I try and use all of my production. As for rain, its great - cleans my panels for me :)

Remember with batteries there is degradation with every discharge, where it makes sense when you are talking about peak price, it likely doesn't make sense when you talk about the much lower sale price. The power company pay far less per kWh then then you pay them in many cases Batteries are wonderful, but they do not last like solar panels.

Again a great video I live in a more cloudy, wet climate (Ireland), for me a battery is essential for all of the reasons that you mention plus: When sun is interrupted by clouds, solar production goes down so the battery can take over and supply thus minimizing need for grid At times of low usage or load from within the house - that battery can charge thus minimizing excess solar from escaping to grid In winter time, Batteries can be charged at night with night rate electricity and used during peak periods As you say - South facing panes are most efficient - but without batteries - much of the solar will escape to grid

I like the idea of solar carport or gazebo for ease of access or ground mount if you are in the county with the space.

If the termites do not get to them on the roof a wooden under a metall sheeting (with some space for aearation of course) should also hold up in semi-arid areas. of course that was German engineering so unthinkable ! to use plastics forthe frame ;) There is a consumer protection agency that does tests, who would have ripped apart a company that manufactures like that, or a solateur (plumber) who is cluless enough to work with such materials.

Hello there. Forgive me but... Is a 3 KW battery enough? I've been doing some calculations and digging... Most household electronics consume little but a fridge, a washing clothes machine and computers can reach around 1-2 KW/h of consumption.

If the grid goes down a transfer switch isolates the SolarEdge panels and LG battery from the grid and feeds my house through the battery. Thus far, I haven't had any issues with the system and my wife loves the fact that we haven't been charged for electricity for months. The hardest part of getting the install was convincing my wife to get the install. Note, however; I researched the perspective installers before committing to a reputable local company.

[@navyretired230]

I thought I would share some lessons learned from doing my own solar install. Date of install end of Dec 2021. 1. If you pay a company to do your solar install, I seriously doubt it would ever pay for itself over 20-25-30 years. I also doubt your electric bill will be zero in the summer months as most solar companies flat out lie. Being inform, you can have them put their expectations on legal papers for your future safety. 2. If you do your own solar one can expect a 4-7 year return on investment. You will have to get educated on permits with your local city and power company. If I can do it anyone can. 3. Power Company Billing was my biggest surprise from this entire venture. Rocky Mountain is NOT solar friendly to the average home owner. The excess power sent to the grid for storage comes at a great cost. I discovered after a few months of billing that We pay RMP .077 cents per KWH. When you generate excess solar power, the excess goes to the RMP grid but RMP only credits you .04 cents per KWH. So, in others words grid storage is not free or cheap. RMP skims nearly 50% off the top. WHAT DOES ALL THIS MEAN: 1. When you have your solar designed and drawings engineered you have to figure in 1/3-1/2 larger system to make up for the RMP skim ratio. I was lucky and added 30% more panels then necessary because I wanted an electric water heater. So far my last 3 utility bills have been $13 the minimum fee RPM charges and that includes free hot water. Jan-Mar our bill was $45-$60 due to winter clouds with a typical electric bill of $100-ish in the winter and $375 in Summer RMP resets the homeowner grid storage to Zero March to March. Of course, RMP keeps the excess storage when the clock is reset. We lost $15 storage credit. Yep RMP keeps your excess after Mar billing is closed out and you start your grid battery storage at zero. This feature does not encourage being "green", It flat out encourages running ones AC to 68 degrees in July and August and push less out to the grid. So during the day your system pushed out excess power to the gird at .04 cents and at night you buy your power back at .077 cents. Yah get the KY jelly ready. 2) Another big disappointment is RMP in Utah takes ALL the homeowner carbon credit rebates. Most states let the solar owner sell the Carbon Credit which can add up to $100-$300 per month passive income. If Utah is serious about encouraging Solar for Homeowners the laws need to be changed. Only serious pressure on our elected officials will we make strides in Solar. Conclusion: Overall I am happy with my solar only because we did all the labor ourselves. We expect near zero ($13) per month electric bills from here on out. Beware that many States like Florida have increased the $13 minimum to $30 now.... so that must be our near-term future for residential solar. This year the homeowner will still be eligible for a 26% IRS rebate and up to $1200 Utah rebate. The crazy part of the Utah Credit: You have to pay $30-$35 ish bucks to set up a Utah Rebate account in order to claim your solar rebate. Another shocker! The 26% Federal IRS rebate for DIY is only for cost of materials. Your Labor is not deductible. One can however hire out parts of the job like mounting the rails and running electrical inside the attic. You will need receipts for the rebates. Pros: We find that it is more cost effective if we run our home ac at 68-70 degrees during the day and raise it up to 73-75 at night. The heavy use during the day results in less RPM skimming off grid storage but just enough to run the ac at night and draw from our grid storage. Not very "Green" in my mind but it is what it is. Con's: One has to be aware to not have too much excess "Banked" on the grid when March comes a knocking. You lose all excess. So in others words crank up the electric heaters, electric blankets, leave all the lights on and dry ones hair more often. Excess storage is not a tax deductible loss but should be! So in other words you have to manage your usage. Does not require much time but it is another thing to do. About 10-15 minutes a month. Bottom Line: Would I do it again? Absolutely YES. I would not hire it out but if one uses their own elbow grease and fill in with some contracted work it is well worth it. Yesterday was 92 degrees and my total draw from the grid was zero. I actually pushed 40kwh to the grid. What is 40kwh? enough to run 40 100w light bulbs for 1 hour or 4 ton HVAC system for 6-8hrs

Anyway, in our first year we had essentially service fee bills ($5-$15) from the months of March through September, and that is before our state payment. We produced 14.2 mWh for the year (and weren't hooked into the grid until late Jan 2021). Even with 3-4 months of low solar capture (the winter) it's been worth doing and I think will pay for itself in about 3-4 more years. We run a small farm so we use basically 2x the amount a regular home would. We'd wanted to for years. So glad we did finally.

I realize that this video is a year old but I love it! I noticed you mentioned LG but they are now also out of the solar panel in regards to being a manufacturer. But they may honor their warranty. I loved LG phones but their not into cell phones anymore. Their appliances and television technology are still going strong! Again, you have given me an excellent starting point as the technology is changing so rapidly. Oh, I'm 69 but I sandblasted and painted railroad bridges over the Missouri River with no safety equipment (not recommending that!), etc. So I've always pushed myself and I'm fortunate enough to be an excellent shape. But not everyone is, through no fault of their own. Oh...you can also piggyback lithium batteries. But you have Telsa which is excellent if installed by Telsa (current waiting time is 9 months). You spent $10,000 10 years ago. Just a good whole house generator can cost that much!!! Haven't touch on rebates, tax incentives, excess electricity purchased by your electricity provider (varies by state), and the list goes on and on as they keep changing every thing!! Love your ending comments about battery storage. My only negative is that I was going to subscribe but you charge $1.99. I've never seen that before.

[@mikemx55]

Just to clarify, one of the reasons of no power in a powerout, is the same reason to not plug a generator in a house without disconnecting the main breaker. Because the inverter can't disconnect the main breaker, that would mean that your power would be feeding the whole grid, and there might be someone out there on the lines fixing it up on a pole, on a live wire, which should have no power and might get electrocuted. There are special generator inlets that automatically disconnect the main breaker for that reason.

[@sharperminds4315]

Correct, but most microinverter setups such as Enphase, have a Gateway module with a transfer switch (such as Enphase Envoy) which can help disconnect the main panel from the grid. Enphase has a new microinverter line, the IQ8 series which can stay active during a power outage once the transfer switch shuts off the grid tie.

My Break Even years:: In Houston, TX I pay 10 cents per Unit of Grid Power. My annual electricity bill is U$ 1100 (Winter months $ 400 and the rest in Summer). My Solar Co quotes U$ 28,000 for 6.5 KW panels with 50% storage capacity Battery, inverters etc all installed with 10 yr warranty. I don't know how much would be the Grid Power cost in the future. I assume it will be in line with the National Average increase. For me to recoup it will take >20 years! I may not live in the House that long. Most of the solar vendors will not be around when I need them. So, I am very discouraged to go solar... For any cost conscious home owner, Solar is not a favored route.. But, if you love "cleaner energy" and new technology, go for it.. In Houston, 22% of the Grid Power has "renewable energy" already juiced in. Most Solar Companies advertise very misleadingly with "Make Money by Going Solar!" slogans. No one tells that it will take >20 years to recoup the Total Cost. The cost goes up if you finance the cost at 2-2.5% interest rate for the money you borrow from the Co or your Bank. Solar Co are not honest in Advertising their Product & Services. Sad... :+((((((

While solar is getting cheaper all the time, your first position should be LED lights and then your next position should be extra insulation. Then you should consider getting window units if your HOA allows them because they lowered my electrical consumption by 45% while keeping the house cooler in the rooms I was using and extending the life of my central air conditioning unit. Next would be the best air conditioner or heat pump recommended for your areas mixture of heat and humidity. Then finally you want to look at some kind of storage plus solar. These are really to be viewed as more for natural disasters than for day-to-day use. You don't need a ton of power to start with. You just want to be able to keep your freezer and your refrigerator going plus a fan and a couple lights. Then finally if you're quite well-off you can start looking at a bigger system. Which will probably dropped another 20% while you were doing all the other stuff. And everything else you did is going to mean you need less solar power.

[@gerberjason6947]

Great video! Just a couple points. 1. I bought my system in 2012 July for my home in Japan. Maybe it's different here, but my inverter has a socket - the guys who installed it told me that if the grid ever goes down, the panels do not stop making power, and I can plug into the socket and power what is needed, e.g. the fridge. Might want to look into that for your next inverter. 2. I have time based pricing, so I have always wanted a battery. However, powerwall, for example, costs about $10k. Based upon my calculations, and considering a life of say 10-15 years, there is no way I could recover my intitial costs. Note, I pay about 14 yen per kwh at night and 28 to 38 yen in the daytime. My solar panels are about 3kw.

[@ehombane]

1 it depends on how thew system is designed. And the stop while blackout is for the systems that feed in the grid the surplus. It is possible that the panels feeds only the house and waste the surplus if there is no battery, and hence, no need to stop producing for the house if the surplus does not goes into the grid anyway. But this will be an weird system. Also, the system can feed the grid, but have a gateway that will switch the house to feed on the solar system and the eventual battery, but shut off the grid, and in this way the grid will not be not affected by the local production when there is a blackout. It seems that he does not know about this piece of equipment. 2 Damn that time pricing sucks for batteries. You store expensive energy to use it at half a price. But you did not mentioned how much you get paid for your surplus injected in the grid. Also how many blackouts are there. Depending on these the battery may be worthy. Pushing the things to absurd, and imagining, random 10 minutes blackout absolutely every night, than a battery will be worthy. Sure, not an powerwall, but a cheaper one, to cover those 10 minutes and some more. I bought an UPS for my computer even blackouts are extremely rare. Let say twice a year. Few years back had one or two every winter, but in last 5 years had none. So I paid 50 bucks for the UPS, for peace of mind, not for recovering the cost. Why for things like solar and batteries and electric cars we need to compute the return of the cost, but we never look at recovering the cost when we buy everything else, from clothes, to all the gizmos we use in the house? Maybe because these things are quite expensive. But a car, or a computer, now even a phone are expensive too. Never heard anybody to look at recovering money for a phone that will last anyway only a couple of years, not a couple of decades. And I am curious about how much it cost your system, and after how many years you recovered the investment. He said, 8 years, for a 10k spent on a 1kw system. He mentioned that now could get a 4 times bigger system for the same money, and energy price doubled. So, ROI close to 2 years. But your system is as old as his, and more, maybe not so favorable located as his.

Thermal energy is where most of the energy gets spent in a house, especially during the peak hours. It seems like it would be a good idea to include some kind of thermal storage and release it during peak hours. Not as flexible as a battery, but it could be pretty low tech. In a house with radiant heat floors, slightly overheating them during peak solar hours and letting that energy bleed down during the afternoon and evening would be viable. There are also heat pumps (Multiaqua is one brand I've found) for production of both heated and chilled liquid, which can stored in tanks and then later be used for domestic hot water and for cooling the building. The latter kind of system isn't cheap, but neither are battery systems.

[@illslim2100]

I do not know if anyone else will answer and I will try and be specific as your first question will vary by your state and local city government. I live in Belleville Illinois. Illinois has made it so the added value to your home does not count against you on your property tax. They did it in such a way that if I sell my home with 22 panels on it, the buyer will be looking at my property tax history thinking they will owe $2600 a year. But in fact, the property tax will go up for the buyer of my home. But, from witnessing my neighbor sell their home and knowing what they paid in property taxes to what the new owner pays. I feel safe to say $400 more a year to have to only pay $11 a month for electricity ever, which is a great deal. The fire hazard, I forget the rate of solar panel fires I was able to find when I researched a few years ago. But it was so small, you are more likely to get burglarized. Far as insurance gouging you, yes some places do try and make more money off you for owning solar panels. I would suggest leaving them and finding a better insurance company. Also, I suggest getting a metal roof with a true 50-year non-prorated warranty on it. This not only protects against fire, but hail and wind damage so well that our insurance company lowered our homeowner's insurance and did not charge us anything more for 22 solar panels on our roof. Getting a 50-year roof is key as if you do a typical cheap shingle roof you will need to replace it in 15-ish years. You will have to pay to have the panels removed and then reinstalled after the new roof is on. That is costly. I paid twice as much for a 50-year metal roof as a cheap shingled roof, but I would have to get my roof done every 15 years, and the cost of roofing your house will go up, but let's say it doesn't. I paid 20k for metal for 50 years or I could have paid 40k for 45 years of cheap shingle roofs.

Your second question. Yes there are options for smaller-scale solar panel systems to power only some things if you want. It might cost more to have your home's electrical system diced up to split the incoming power to only the circuits you want solar-powered. I do not know PG&E net metering policies, but I doubt they are more corrupt than any other electricity provider. It really is up to the state government on how much they can screw you. Ameren here in Illinois does net metering and I love it. I give them the extra power I create all day and get back free power at night or whenever my panels do not create enough power for my home. Basically, for $11 a month, Ameren paid me 11k to get solar panels and is my giant battery. The battery we were looking at for our usage was 15k installed. It would take 113 years at $11 a month to get to 15k. Then add in we would have lost the 11k Ameren paid to us to go solar. Everyone's state is different. Just next door in Missouri they get crap from Ameren./Illinois to go solar.

[@illslim2100]

Now let me get into my cash numbers. My 22-panel system was 41k to install and I received 11k from Illinois/Ameren and 13k from the Fed, making the system total out-of-pocket cost 17k. It took 18 months to get my money from Illinois, they also are holding $600 hostage to make sure I stay on the grid, big deal. It took me two years of taxes to get all of the Fed tax credit as I do not make that much to cover 13k in non-social sec taxes and only actual federal taxes. If I only used the money I would have owed Ameren to have paid off my loan it would have taken 7 years to pay it off. I paid a little extra to it and paid it off in a little over 2 years. If I had stuck with a 7 year pay back my estimated savings at the time of installation was 80k over 30 years. But, I paid it off early and Ameren raised our area's rates 45% in Jan 2023. My new estimated saving is around 115k in 30 years. Add in we now have an EV and will not be paying for gasoline our savings is even higher, around 220k in 30 years. My panels are warrantied to be producing 92% at the end of the 30 years. We will be dead and our home will still only pay the connection to grid fee, solar panels will still add value, and the roof will be in decent shape. When people are paying over $1000 a month for electricity bills, we will be paying only whatever the connection fee will be at that time.

I am always happy to answer questions about my metal roof and solar experience and what I found when researching before buying a few years ago.

[@pavel9652]

Get mid to high range portable power station such as Bluetti AC200MAX with 2kWh battery on-board and install in the garden up to 1.2 kW of solar and you should be able to use it quite well. You can power some devices at home, use for trips, as a charging station or in the workshop. See what output and input ports it has. The cost would be around 2.5k, including circa 1k spent on panels. For trips you might want to have a portable panels, though.

[@junkerzn7312]

Yah. I've had my panels for 15 years... still a small system though, with 2 x 9 (18) old 160W sharp panels. Only produces roughly 2000W at peak now. Two high voltage strings going into a string inverter. I'm struggling with deciding whether it makes sense to add new panels to the existing roof, or to get the roof replaced first. Only reason why I haven't upgraded the system yet. I did have to replace the string inverter once. The first one failed after around 15 years. As expected. Replacement was trivial though, no need to go up on the roof and that has pretty much sold me on using string inverters. I don't have shading issues in my particular case. I really love the system, and I don't even have any smart monitoring or pretty graphs to look at! Just the LCD display on the inverter which doesn't really record a whole lot past a month or so. Instead I pop outside and look at the power company's smart meter every once in a while. -- But now I'm adding more electricity use. I recently had to replace my 30+ year old gas water heater and decided to go with a Sanco SANCO2 heat-pump water heater. Expensive, but I really love the system. And my AWD ID.4 order is now locked so hopefully I will have a new EV to replace my 21-year-old Audi A6 in a few months. Because of that, I am really starting to seriously look into ways to upgrade my solar system. -Matt

[@byronlazo]

I'd say get a new roof first and have full peace of mind. I did the same even though they said my old roof would hold up.

[@LiLBitsDK]

if you are even considering to replace the roof then the answer is "no, you should not install solar without replacing it". replace roof then slap solar on it... having to replace roof AFTER solar is installed is a major pita...

[@greatpix]

Something for everyone paying for electricity to consider. The water level of Lake Mead is something like 120' below what it was 10 years ago. The lake powers Hoover Dam which is a large source of electricity for the Western states, In the past 5 years water level has dropped so low as to come within a few feet of forcing a shut down of Hoover Dam's generators and only been prevented by water rationing in the affected states. Solar panels will be in high demand when Hoover Dam's generators shut down. Not IF they shut down, WHEN.

[@Engineer9736]

Because the entire world runs off Hoover Dam? 😂

[@magatism]

Us will have a nuclear powerplant adjacent to the dam by then.

[@greatpix]

@@Engineer9736 I did say "western states" but I would bet some of that ends up being transferred to other states in time of need, except Texas as they're "independent" of the rest of the country, as they learned to their detriment during the past 12 months.

[@greatpix]

@@magatism Those are great, and at night everyone can see their way around because they'll be glowing in the dark from the radiation. (just kidding) There ARE health concerns living under the bigger power lines. A good trick is to stand near one with some neon bulbs in your hands and watch them light up all on their own.

[@magatism]

@@greatpix Or you could go off grid and enjoy some real fireflies, get out of the rat race, enjoy nature and the clear blue skies...

[@ashforkdan]

35 cents a watt for used pannels. They put out the same as when they were new. Build your own system. When I went off grid it cost 5 dollars per watt. Just do it and disconnect from the grid.

[@forestMog]

Would it make sense to install new panels, then later expand system with used panels?

[@ashforkdan]

@@forestMog I run 40 -240 watt pannels and they put out the same as if they were new and at 30 bucks a piece you can't go wrong. I'm putting 50 pannels on my shop and running 240 for welding and tools.

I appreciate that!

[@dawnwokson8202]

Very well presented video,Although I'm completely offgrid in my Airstream I enjoy watching informative videos on solar. For me solar is a lifesaver. And it saves me from having to use gas and propane on a daily basis,so now with those prices going up I plan on saving even more and if,when the power grid goes down I'll be fine

[@eunickissimo]

14:50 yes man. By the way, here in Brazil, 90% at South hemisphere we use to place the solar panels at the North side for the exactly reason to maximize the generation through the year. Specifically here in southern region of Brazil, below the Capricorn tropic where the sun never "switch sides".

[@Jackson-T23]

Going solar really is a regional decision. I have family that lives in San Diego, and if we lived there I would go solar (lots of sunshine, high electricity and gasoline costs, low energy demand, and good rebate incentives). In the area my relatives live, they hardly ever use AC or heat at all! We live in North Texas and the situation is almost complete opposite. Gasoline is cheaper. Electricity is also much cheaper (we pay $0.12 kwh) but usage is very high because we have 13 tons total AC running in the summer. Even with a giant solar array we still would have a sizeable bill. I don't think our roof is big enough for mount a 12kw system, nor is our wallet. In the winter we have gas furnaces so solar panels won't help, nor do the months of long cold cloudy days. The other problem we have is dangerous weather. We get tornadoes regularly here, as well as storms that drop softball sized hail.

[@Kishacollectionsbymanisha]

but you have soil so you can grow plants/trees in your area which would cool down the whole are in a long run.

[@chada472]

I have been doing solar since 2007. I have added on and upgraded over the years. There are areas that could save lots of money such as my case. I went from a $3600 a year utility cost down to less than $300 a year!

[@ricellisfrost620]

Great video, thanks. You haven't mentioned using 12v DC devices. 90% of all household devices comes in 12v versions - fridge, TV, all lights, charging etc. This will reduce your demand significantly, bypassing your inverter... the gains are enormous.

[@BradKwfc]

The problem there is the power consumption is the same, so with a lower voltage your current demand is higher which requires bigger wires & more robust control circuits. High currents also mean you have higher IsquaredR losses.

[@whateverthisis3929]

In Australia and you wouldn't believe how good solar is here, we have 7kw installed and it's brilliant

[@Enonymouse_]

Solar is successful enough there i've heard it has destabilized the price of power, so persons expecting to make money by feeding back into the grid are losing money.

[@whateverthisis3929]

@@Enonymouse_ that's exactly the problem our state is facing now, it's the result of the government not planning ahead with large scale storage projects to match the huge uptake in solar. Every other house has solar here, but our state has one big 50MW lithium battery, it's fantastic, but nowhere near enough to balance the renewables out.
