I thought I’d have to spend a lot of money, but it ended up being cheaper than ever to get my solar system feeding back into the grid. It used to be that you had to …
Use all of your electrical devices during the day and you may not be back feeding, but consuming everything you are producing during the day, and not using the grid as much during the night since you did most of your electrical needs during the day.
Panels aren't getting cheaper because of government subsidies.
You could (possibly) wire two of those panels in series, and connect them to a micro inverter. That would kind of mimic a larger '24 volt nominal' panel. Check of course that the micro inverter can handle the output of the panels though, for safety. (Should only 'use' what they can handle but… cheap Chinese things… never know. :P)
Those inverters like you got are fine, if you don't need it to be UL listed.
Good video. Thanks Dan. They finally allow net metering here in Lubbock, TX, but I use so little power, usually less than 50kWh/mo that it would actually cost me more to do net metering because they increase the base fee from like $8 to $20/mo and you don't get any money back from producing more than you consume, you only get what you use cancelled out. I've thought about doing it anyway, just to get the co-op workers more experience-maybe eventually they'll make the terms better if enough people do it. I guess it might still make sense for large consumers. I've got most of the components for an off grid system, so I guess I'll probably do that first.
Check the laws where you live before you do this. In my area this is illegal and could get you in a lot of trouble. A battery solar system is a better way to go.
They just passed a a tariff on all overseas panels so no more cheap Chinese panels at half price… Only if you have a analog meter on your house still, my utility just switched out my analog for a 'smart meter' which now you have to actually get their permission to backfeed onto the grid I can no longer do it with meter!I now have to get batteries and a limiter grid-tied inverter to tie into the house, the limiter inverter will not allow feedback on to the grid…
Just connect the panels in series, in pairs. Enphase micro inverters will not burn out, they just reach saturation, and then use only that much power. They actually recommend oversizing the panels in order to achieve maximum watts per dollar spent on the inverter. They can handle 60 -72 cell panels. If your panels are 12v nominal, they re probably 36cell panels. hook 2 of them in series, and there you have 72 cells and the right voltage. Enphase M250 or other size micro-inverter should work fine, just check hertz, and line voltage. if you have 250v, then power the overall 250, not just one leg. you can pick them up for about 75 dis each used on eBay. they re like 125 new each.
Can we install them easily ourselves?
I am thinking for manufacturing solar panels and installation inexpensively much less than solar companies are charging home owners. This will reduce cost of ownership and make them affordable for more home owners.
Thanks again Dan, for putting things in perspective.
Thanks Dan. As always, you provide some great information. Congratulations on the 20th anniversary of Dancing Rabbit Eco village.
Dan, love your videos. I'd like to hear more about your DR micro grid – "BEDR"? Wasn't sure what you called it. My biggest question about using the micro-inverters would be how your micro-grid system supplies power during off-peak solar hours (evening,night,early morning). I am considering PV at my off grid cabin but would want power at nighttime. So maybe a battery based system is better for me? I'm interested to hear how your community handles off-peak power demands – is your micro-grid actually tied into the "real" power grid for those demands? Thanks!
Interesting info, but I'm pretty sure I want a non grid tied system. I just have no faith in the power companies, and anyway what good is having your own power system if it goes down every time there's a power outage?
DAN Tho's are NOT ok to use in the US. Your is fine as your have that cool setup with DR. But tho;s of us in the rest of the US if we back feed with tho's and I did I had 4kw of tho's and 4kw of pv. I set it all up. Was making a load of power. Got my bill and BAM it was 600 KWH more, When I looked into it The Power I sent back to the grid I was being made to pay for it.When I asked the Power Co-Op why. They told me Tho's are not UL listed so they can't be used and that I must have a net metering contract.
Your so lucky you can use them. One more tip to get them to last a long time. You may need to look into buying 2. Then brake it up. That will keep it from getting hot and running the fan as much. After I got my SMA micro grid tie 2500 watts setup and did all the stuff to get my net metering. I did reinstall the wall deals for a wile. One day my wife not knowing let a friend of a friend come over. She worked for are Power Co-Op. She asked about my solar and my wife showed it. When she seen the setup. She Told someone at work about it. I end up losing my net metering for 8 weeks. Now I have it back. But I do not grid tie as much Just have one 250 watt SMA micro grid tie going. The rest of My pv is on my off grid. We now do not buy but about 50% of are power in the summer and even less in the winner maybe 90% in the winter. End the end it works out best for us. The summers are hard here in SC with the heat and my health. So I must have AC that is why we buy as much power as we do. In the winter I do not mind being cool. That saves us a lot.
Lol So I told you all of that to tell you I found tho's plug in guys work and last the best if you run them with less than 50% of there power ratting.
You know I am not trying to be a ass. Just would hate to see someone do what I did and end up getting in big trouble or at less costing them loads of cash.
What happened was Chineese imports. The US companies are currently lobbying hard for increased taxing on imported pannles. This (corporate welfare in my opinion) will decrease competion, drive up prices and stiffle innovation. But thats just my libertarian opinion.
I love your channel.
