We got the 30% federal rebate, nothing else as I did the install myself (losing the $2,000 state rebate, but saved 10 grand by making the racks & self install) I'm looking at a 10 year pay back on a system that's guaranteed 25 years and should be good for 40.... I won't be here to see! No batteries, grid tied. The extra power goes to credits that are good for one year. They do a 100% even trade but will never pay for extra credits. Our bill has been $6.85 a month (minimum paperwork fee), but I see this month it's going all the way up to $7.25. *smile*
That's the problem with the solar systems ... ROI is far too long.
And, since everyone here is basically in the northern region, I have examined through FOIA requests responses of various PV government programs and contacting folks who did install systems that their ROI's were about 15-20 yrs. 'cause ya get no output in the winter months (what ~ 7 mos out of the year).
Our latitude on earth just makes it that way...very poor generation of electricity. If you are going to do this .. recommend you store the electricity produced ~ the only advantage of solar is for preppers. But then your stuck at that location ... which many preppers don't like.
So if interested before you listen to any "sales" pitches...do a FOIA request and contact folks .. people who install are generally happy to talk about their generation rates.
$17000 comes to 14 yrs for an avg e-bill of $100/mo ... yikes!
