    I recent just got a quote from a company for a 9.9 KW system. Price was $39,000. System is projected to produce 12,990 KwH per year, or about 112% of my bill ( I know its a bit overkill but I wanted to make sure our bill drops to zero and we don’t have to add later–9KW system was 102% which made me nervous in case projections were off a bit). Looking at SS comments from April though it seems I may be getting overcharged—by quite a bit. I know I only have til 1 Jan to put the system in so looking for some unbiased advice. Do I still have time to get other bids and get one in, and does that price seem reasonable (includes installation etc—credit come later when I file taxes).

    Thanks in advance for any assistance anyone can provide. PS Love the site and all the info on it; looking forward to getting rid of electric bills.
