As the cost of everything goes up with time, because the value of the dollar goes down, the $200 / mon in savings is only going to get bigger!
I have a grid tie system, meaning no batteries. Batteries are costly and require maintenance and will only last highside 6 yr till you have to replace them. So CPS the utility company becomes my battery backup system. During the day the panels make electricity and the meter runs "backwards" and then at night we get home and start using things and the meter runs forward. The goal is to have my daily use equal my daily production. zero bill.
I think you can get the jest of my plan from that. If I have too few panels I will add more till I get to a zero monthly use, with NO plan to sell back to CPS. I want a zero bill. Now I have 60 panels so we will see how that does. Lots of sun should mean lots of energy. By the way it makes my electric car energy really free from the sun! LOL
Be blessed, Billy and Jan
