Yes. Our neighbors got a system installed recently. It was done in 1 day, 3 or 4 people. If they are skilled labor, that should cost $4,000. Of course the solar companies pad their cost by at least the tax credit. I believe the tax credit lowers next year and then goes away after that. It will kill the industry.
I have solicited bids from 5 or 6 companies and they all come in fairly close to each other, on a cost per kilowatt, regardless of which brand of panels they use.
From what I’ve been able to learn, Sun Power panels are the best, most power per sq in, least degredation over 25 years etc. They only sell to installers, and cost more than double of the cheapest panels, but somehow the installed costs are about the same!
