2019 was our fourth year with solar panels. I have added up the bills from APS for 2016 and 2019. 2019 was cheaper by $25 annually. I think it is because we were trying supercooling our home in 2016. It ends up being more expensive. We keep our house cooler that we would if we did not have solar panels.
We have a 20 year lease for our solar panels. The return on investment would be better if we had bought.
