Interesting facts about solar power

unsubsidized cost. In 2012 our cost before subsidy was $3.4 per watt installed on a 9.6k pv system.

Thanks for the info. I'm not sure why the installation I followed would have been so much higher - two big buildings, flat roofs? Should have really gained some economy of scale.

One explanation - it was all taxpayer money (a school district, plus grants). I wonder if any of the people who signed off on it would have paid that much if it was coming out of their own pocket and on to their own home?

I'll try to see if numbers are available for any other commercial scale installations around here. It's usually hard to find the unsubsidized costs, and businesses don't always want to make that public. For the most part, I think they want the PR.

Didn't read it yet, bound to be interesting though.
