Send me a message through PM here or our site. A very good friend is tight with the guys at DOW and I just spent a few days with him in California as solar shingles are on my middle burner for our own home. They disappeared for a couple years but will be available soon if not already in a few states.
It's interesting that there are solar cell shingles out there. I feel like that would really help you conserve electricity. How many cells do you need in order to collect enough energy? I'm really curious about this. http://www.gbsroofing.com
