I'm in negotiations with Solar City at this time. Still crunching the numbers, the lease to me is my average monthly bill divided by something and something = $67 month for 20 years + 2.9 % each year. Excel energy is raising their rates every year by more than that much.

I think that's how it's all working out. Waiting for the wife to meet with the sales chick and go through all the numbers again.

None of my roofs will be south facing, all east or west. But I'm including a detached garage and house together, and they promised 95% of my normal usage via solar, usually 100% plus some.
