For me, I'd pay for the system outright either with cash or through a loan outside the solar company. That's just me though. At a cost of $40K with $12K tax credit; $5K local tax credit; & $8.2K tax break over 4 years; you're left with $14.8K cost to you. That's dirt cheap. Even if you leave and can't recoupe the total $8.2K, it still is cheap and the system might increase the resale value by enough to make up the difference. My system of 25 panels at the time cost me $19+K after everything.
Yes and they are also making bigger panels. 2m x 1m instead of 1.7 x 1m. Some panels are near 500 Watts
