$300 DIY Grid Tie Solar Panel Setup Update
Рет қаралды 55,183
3 жыл бұрынIt 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 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.

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!

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!

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.

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 Жыл бұрын
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.

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.

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.

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.

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?

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.

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 wonder if that has happened to you since this video is 2 years old maybe since you're not making much they won't notice. 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.

I thought about doing just this last night (although possibly 2 x 400w panels with microinverters) and feed into a 240v outlet. The goal would be to assist powering our 12,000 btu mini split, fridge, TV, etc. Seems like possibly the best bang for the buck/effort and it would be a real residential system (last 25+ years, more powerful, more efficient, and far safer. I actually found this video seeing if this might work, seems like it should. The biggest problem I see now is where to get the panels as shipping is costly. I checked CL and ebay, nothing decent nearby and I only see full system "installers" in my state... I doubt they will be willing to sell me panels at a fair price, lol! One word of caution to those looking to do one of these (experimental/under the radar) systems, if you have a digital meter on house, you will get charged for power you're using AND MAKING if you don't have a way of blocking the generated power from the meter!

If I ever get a sprinter van I'm going to throw solar on the top and spend 6 months in it! Got a lot of work to do first though ha...
@BeatTheBush 3 жыл бұрын
=D Live in a van eh? I imagine I might just get by with small amount of electricity. Probably the fridge sucks up the most power to keep things cool.

I know you only have 100 watt panels, but it might be worth a check to see what your voltage drop is between the panel and the house. IOW, heavier wire might give you a boost because that end is DC.
@BeatTheBush Жыл бұрын
I remember doing this check. I spec'ed out the gauge of the wire for the maximum current it will pass.
@rupe53 Жыл бұрын
@@BeatTheBush ... there's a hole in your figuring. After 10 - 20 feet you can get quite a voltage drop, especially with #18 wire (speaker wire?) at LOW voltage. Just a few volts can be a 25% loss!

with 400 watts of panel, you should generate at least 250 watts. I live in the bay area as well. retired chinese engineer. i like to email u and share some ideas of solar and option trading. with option trading, i generate an extra pay check each month.

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

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

Where did you come up with the 0.8kW number in your ROI calculation? That should really be 300 W. Did you mean 0.8 kW-hr/day?
@BeatTheBush 9 ай бұрын
Yes, roughly 800Wh/day due to building shade.

Maybe someone can help me understand the issue of panel output voltage and inverter stated input range. For example in this eco-worthy kit there are 20 panels Vop 18V each, I believe meant to be wired in series. Wouldn't that combine to a 360V output? The inverter used is rated at 45V-90V DC input. If the panels are in parallel the input voltage would be lower than the inverter minimum and in series would be way higher than the maximum. So, what am I not seeing properly? @t

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 3 жыл бұрын
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.

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.

Did you have to tell your power company before I stall a grid tie system? Did they make you change rate plans?
@markm0000 3 жыл бұрын
If you don’t then your billed usage stays at 0 when the solar panels are producing more power than you’re consuming.
@theChef1337 3 жыл бұрын
Mark M its not that simple it depends on the meter. Some places the meter actually keeps spinning if you export power. Among a bunch of other safety issues,, this set up is totally illegal and requires an interconnection agreement with the utility.
