Financing the project here seems favorable. Production grant to take price down right off the top. NYSERDA has a low interest loan and a couple of banks have low rates as well. Even with financing the project, we net substantial money over 25 years. With that being said, I'm projecting electric rates to increase annually at 3% (fair?) and usage to not increase substantially.
Thanks in advance for any help from anyone.
I would just say be cautious about the financing. It sounds like you are on top of it, but there are financiers that charge a low interest rate, but they also add a massive upfront cost to the cost of the solar. IIRC they offered it to me, and if I increased the cost of the system by like 30%(!!), I could then finance it all with a 4% APR loan. It was ridiculous, bordering on scam / usury. The solar installer admitted as much (it was a 3rd party financier) and said he offers it if asked, but doesn't recommend it or push it at all.
