$300 DIY Grid Tie Solar Panel Setup Update

It has been a year since I fist made a video on my grid tie DIY solar system that costs only $300. Since then, I've used the system and monitored the amount of energy it products. I am now upgrading it slightly by using the remaining capacity in the grid-tie inverter going from 200W to 400W of panels.

I noticed when I started looking into solar panel technology I started to realize every watt of use matters! A 60 watt incandescent bulb would consume a high percentage of power (and generate heat that has to be dealt with). LED bulbs would allow me to use 4 to 6 LED bulbs throughout the house versus just 1 incandescent bulb, and the cost of LED bulbs has continued to drop to very reasonable levels. Then one starts to consider devices with inverter technology (air conditions, refrigerators) that avoid surges during startup and sip power instead of guzzle it. Cool stuff!

[@AskIveSolar]

That's why I hear people say to go with energy efficient stuff first before you get into solar.

[@crpth1]

Yep! That makes sense. After all net gain (profit) is a result of what one gain vs what one spend. Reduce your spending and you're already on the right direction! :-)

[@billycomedy]

Love your comprehensive analysis and clarity! Also, you're pretty good on camera ;)

[@slofkosky7641]

Very well spoken and I really enjoy how you broke it down for us viewers. I'm just a few months into my own journey with solar and learning quite a bit too that seems to mirror your own path. My fear currently is feeding back to the grid if I create more energy than I am using from the grid and back-feeding to the utility company. Just ordered an inexpensive grid-tie inverter with limiter during Cyber Monday to try and keep that from happening. It's a 1K watt system with sensors for $232 after tax and free shipping. Anyways thank you for the video!

[@grugnotice7746]

I had no idea this was so easy to set up. I've been on the fence about putting in a solar system for ages. Think I will pull the trigger this year.

[@BeatTheBush]

Well... a temporary system for testing only though. You'd have to mount it properly so the wind doesn't blow them away.

[@robertlane6675]

I have pretty much the same setup and I added relays, a charge controller and battery. I have a 12 volt wallwart keeping the relay n/o terminals closed. If the power goes out the relays direct the current to the charge controller. This way if the power is out it automatically starts to charge a battery and disconnects the grid tie inverter. It adds a few bucks but allows you to use solar during grid down events. I enjoy your videos man.

Hey man, thx for the tutorial. I am looking at a similar low cost entry into solar with maybe expanding down the track after gaining first hand knowledge, I think same as your outlook :) I'm an expat over in Thailand so all the components are a bit cheaper and the hours of sunlight are quite a bit more..........but it's hot, so equipment fails quicker.......so I'm looking at maybe using only half or less of the available wattage plus maybe adding some (solar powered) cooling fans. It's exciting to even think about doing it so will be even more so actually starting :) I thank people like you for helping me get going :)

[@blazeinthesky130]

That’s awesome thanks

[@johnwyman6331]

Thank you for making this video. I think your math is a little misleading though due to the smoke in the atmosphere right now. Once that gets cleared you should get much better output and ROI. Not long ago the utilities put smart meters on all our homes. If you have a smart meter on your home and you backfeed the grid through the smart meter they will actually charge you for every Watt hour you put out onto the grid! This is why that same inverter company has come out with a gridtie inverter with limiter or GTIL. It has a sensor that allows it to only produce the amount that you are using in your own home and not backfeed that smart meter. You can charge batteries with your setup. You can connect the positive and negative charge controller input wires in parallel between your panels and your grid-tie inverter.

[@Good-Enuff-Garage]

luv your brutal honesty ! one thing I would share with you is that your 400 watts of solar panels will generate closer to 50% of power so 200 watts so no where near the 500 watt "limit" of that little inverter, so you can safely add two more panels for a total of 600 watts, hewk you can double them to 800 watts and still be fine

[@BeatTheBush]

With them roughly flat, I get about 62 watts from a 100 Watt panel on a sunny day. There’s also needing to size for corner cases as well as leaving some headroom to maximize reliability. The inverter is pretty cheap so I wouldn’t want to push them to 95% limit. Current I have 4 100W panels and I think that’s the most I’ll do.

[@Good-Enuff-Garage]

@@BeatTheBush cool try using an Emporia smart plug in front of your Killawatt meter and you will get nice wifi software and a graph output over time of how much power they pull, I am doing just that

[@kpboix99]

I am ready to live off the grid too 😀

[@BushImports]

I've been thinking about it but probably not a grid tie setup. The holdup for me on doing solar is being able to build batteries with as high or higher energy density as/than lithium. Lithium batteries are way too high for me to want to spend the money even in the case of a power outage , usually the outages here don't last long enough to make it worthwhile to do that.

[@somanyfnbananas2774]

If the grid tie inverter ever fails it is normally a relatively easy repair if you are familiar with soldering and a little troubleshooting

[@tubejim101]

Great video.

[@BeatTheBush]

Glad you enjoyed it

[@wayne19922006]

Hello great 1-year old video. I'm building the same setup (for educational purposes only of course). A point I would like to make is that the size of the inverter is what limits the output watts not the number of panels. The number of panels can exceed the max rating of the inverter if you want to make sure the inverter is running at the max. Another example of what I am talking about is that you can connect a 12 volt 100 amp battery (1200 watts) to your 500 watt inverter and you will only get 500 watts out.

[@BeatTheBush]

Interesting. I guess I would never buy more panels than the inverter since it'll be a bit of a waste. Also, I think it's best to leave lots of headroom for these cheap inverters.

[@wayne19922006]

@@BeatTheBush Hi, if you are not getting the wattage you were shooting for maybe because of the season, angle of the sun or some other reason it is acceptable to add panels to make up for inefficiency. I hope you have a great day. I am anxious to watch more of your videos.

[@tchamp72]

I love this. Everything else I've seen is much more complicated. In my area, electricity is only 8 cents ($0.08) per KWh, so it just doesn't make any sense for me to do any kind of solar. Did the math on this, and it would be 12 year ROI minimum, which might be more than the life of the equipment. Maybe I can do it for wind instead. There's plenty of that here.

[@AskIveSolar]

That's kinda my scenario as well but I already have panels so I still want to try this. I just have 2 100 watt panels. I just wanna cover cell phones, wfh and tv watching./internet.

[@macrumpton]

If you did this with used panels you would have a faster roi. I have seen 260w refurbished panels for $100 on Offerup, and even if their output is only 200w (worst case) you are doing far better than with new 100w panels.

[@Stephenphillips29UK]

Pay back in the UK would be around 6 months here as our electric rates are expensive!

[@simpletongeek]

I think some kind of battery charging system is necessary to balance the output. Even if it's something as simple as mega capacitor. I can use it to charge Jackery portable battery, and later attach my portable rice cooker for dinner. Of course, charging laptop for late night computing is an option, too. In fact, 0.5 kwH average during the day should be enough for my daily consumption. Substitute cooler for fridge, and that's about it.

I am going to try this with 2x100watt panels and a grid tie inverter, maybe one like yours, or the micro inverter that hooks under a panel with 2 connectors. i am not going to notify the utility because i am going to run it on the circuit that my swamp cooler is on, so i will turn my swamp cooler on, then plug in this system to the same outlet, my swamp cooler pulls 220watts on low, so this should put out less than my swamp cooler and just help lower the usage with no back feeding at all. so the utility should see no reverse voltage or my meter go backwards

[@nichethought6106]

i am trying this to learn more about solar. I got 1000 watt 24Volt grid tie inverter. We have not worked to conserve power yet. i know we will burn all the power and not be sending any to the grid. Also know that at .06 per Kwhr it will never payback to call it an investment. About the same ost at abbout $300. I am just funding my solar education for later in life. I will be able to help my wife and i learn before we retire and move south where solar should be able to get a return.

Most utilities now the smart meters will alert the utility that you are using a grid tie inverter they will send you a letter telling you to remove it. Monopolies don't like competition.

I think there are inverters that have a way to shut off the back feeding they use current clamp goes around each wire feeding from the meter to your panel each 120V leg and it only turns on the inverter when it detects power flowing in from the grid when you turn something on.

MPPT inverter. After I watched your video, I set up my DIY 400W system near my patio. Question: Howcome people said to set up my Solar Panel System grid-tied and connected directly to my MPPT inverter is not recommended as this will not only harm my inverter by putting high loads of power directly into my inverter, but it also has a low-efficiency due to its conversion (DC - AC - DC). It will be better off to put a charge controller and a battery bank to help me in the long run by protecting my system. However it will increase my initial cost, and more things need to replace in the future. I don't get it!! Are they trying to spend more than I need?

[@BeatTheBush]

Disclaimer here that when you set up your own DIY system, you still have to follow code and you're doing it at your own risk. With that said, if you go from solar to inverter back to using electricity somewhere, you lose efficiency at about 20%+. It's more efficient to just produce DC and take the DC back out.

[@HyPex808-2]

With a grid tie system didn’t you have to have the utility come out and check the wiring? After the inspection they give your the green light to proceed and a turn on date no?

[@rootcanal7188]

Thanks for the video. Without meaning any rudeness, please consider this feedback: if you don't have batteries to store the electricity generated by the solar panels, you will obviously be in the dark if the grid goes down. From what I have been reading lately, there is at least a fair chance of that happening. As for your 500 watt inverter, that isn't much. I just got a Ecoflow Delta portable power station. It is basically a 1100 watt-hour lithium battery, plus a 1700 watt inverter, and the protection circuitry, in one box. I have four solar panels to charge it up if the grid is down. I can power the refrigertaor and a chest freezer (and maybe a few more things), and charge it through solar panels while the inverter is running appliances, Again, no offense, just some honest feedback.

[@BrainstormerQ]

Of course one can install batteries, and while you're at it, might as well fill the whole roof with solar panels. the whole point is to do it as cost effective as possible with fast ROI. having batteries would defeat the whole purpose of what he's trying to achieve. I'm sure he doesn't mind being in the dark for a short time vs having to pay all that equipment off in 20 years.

[@dirtsailoroff-road5580]

so can I really just plug the grid tie inverter into a regular outlet in my house???? is that what I'm understanding?

[@BeatTheBush]

You have to have the contacts in place with your utility to do so.

[@dirtsailoroff-road5580]

@@BeatTheBush yes, I know I have to contact them first, but the actual physical part, is it really just that easy?

[@winyoutube]

one doubt : why did you add those new panels in parallel to the converter and not all in series ?

[@Laser2120]

He said his inverter was 24v id imagine he didn't want to blow it up

[@BeatTheBush]

@@Laser2120 You have two in series to make 24V. If you put them all in series, it would be 48V. So that's why you have two sets of 24V in parallel.

[@zachofalltrades6116]

did you have to contact the electric company and change your meter.

[@BeatTheBush]

Yes, you may have to sign up for net metering from your utility.

[@robbyschulman8077]

Could a system like this be used to just charge an EV car instead of going to grid. Would that make the car energy free?

[@sallerc]

Yep, with 400W (peak) it would take a looong time to charge it though (you wont get many miles/day).

[@johnwyman6331]

Might be about right size for a solar charged electric bicycle though.

What exactly is a Grid Tie system? How's it differ from other solar systems?

[@BeatTheBush]

grid tie means no battery. feeds energy into the grid.

[@kitsurubami]

Why do you need the ac breaker before plugging into your house?

[@BeatTheBush]

It is for breaking the circuit for anything plugged into the same circuit as the grid-tie. You need that there or else the solar will just keep power it during a short.

[@cryptohuntertoken1014]

What about the floods what you do then

[@BeatTheBush]

Stand on the panels and surf! Make sure your buy property with high enough elevation?

[@chino4887]

Do you have the Grid-Tie inverter on 24/7 or do you turn it off at night and back on in the morning?

[@BeatTheBush]

The grid tie inverter draws

[@JordanEE]

How is the inverter holding up?

[@BeatTheBush]

Still going.

Why do all these guys record their videos on cloudy (or in this case, smoky) days?

[@dave597]

6 year ROI? Would you have bought/invested in these if you weren't sent them for free by the sponsor? Are any of these projects worth it if you didn't get the products sent for free? It does not seem worth it for anybody to try this at all unless you got the product for free.

[@paulstone7655]

The smaller panels aren't worth it. Better to buy larger (300-500 watt panels), and in bulk. A reasonably priced system like this can pay for itself in around 3-4 years.

[@correctionguy7632]

A 6 year ROI is a 16.5% annual return. That is pretty good though not considering how much time he spent researching this stuff.

[@deathskull77]

you really should upgrade the wire gauge connecting to the inverter for safety reasons. Dont want to burn down your house because of the wires getting hot.

[@BeatTheBush]

Hmmm. I did some calculations for power carrying cables vs wire gauge. Seems like I’m about 10% under in current capacity. I guess I’ll just double up before summer comes.
