As far as my system paying for its self...lol...not in my life time, but that’s not why I got it, I paid for it up front, and yes I could of found a better investment for the money, but I just didn’t care..put $61.000 dollars into it so I guess u could say I have that brand new big a.. truck on my roof!I don’t have that info. For me there is zero up front cost. And as I mentioned in the book lol, the solar installer cut me a check to cover the first year of payments. It will be roughly $200 a month until the loan is paid off. After that it will be nothing at all except any upkeep and occasional battery replacement. The batteries are currently around 2k a piece. I have 3 and the cabinet can hold 6. You can run up to 12 on 1 inverter so if you have the cash you can go big and run much more of your home with it.
I’ll be able to tell over time how much lower my power bill will be. I’m hoping it’s significant. Bottom line is I added $200 a month payment so I’m hoping the power bill is much lower. It’s great to have the backup and assurance that when power fails, I’ll have cold and frozen food and hot water. Also the other outlets that we tied to the system.
