I have a brother in law that works in management for the power company. He wasn't an advocate of alternative energy, for years.
Then with low interest $ - rebates and incentives - and that CMP will buy back his power at a higher rate, he put a whole array on his roof. He's a staunch believer, now.
I wish we had some of the same programs here in Maine. I looked into covering a south facing roof but the figures didn't make sense. I'm hoping we can get some local movement to do a community solar panel farm that we can buy into.
