HI Wannabegreener.
Those are all excellent prices you are getting for your system. We are also in S NH and have shading issues especially in the winter so we went with 24 LG300 and Solar Edge optimizers in a 7.2 KW sized system with a 6KW inverter. Our shading and system losses on PVWatts, and verified by several companies (using a Suneye tool) is calculated at 27% loss on production.
It has performed very well, and we are on target to generate 8000KWH (5400KWH as of August 15) this year which is 80% of our consumption, and when I look at your consumption 6500KWH why do you need such a large system? Are you planning on adding more load like a EV car, or heat pump?
Even with panel degradation over the years, a 6KW system should produce 90% of your needs for the first 5 years unless you have severe shading - I would have someone do a true analysis of the shading first.
By the way you are getting excellent prices - anything under $3.50 is very good, and as others have said, don't just go by the reviews also look at the time in business and longevity of the company.
