Just 20 years based on your average energy use, and a 2.9% markup each year. Not really "free".

You'll still be paying the $70 per month rate to solar city if you use Zero energy for that month, like a long vacation.



I'm still in a fight with them about putting on the larger system to my house. They finally responded with the "comments" of my 2nd engineering review of the house:

" You do not have a load bearing wall. "

Huh? I think someone missed something here during the inspections. There is a load bearing wall, steel I beams, posts. I'm still waiting to hear back from them.


Update: I have produced 20.27 kWhr on a single day. My high so far. Looks like the average is 10-15 kWhr on the sunny days.
