After a conversation with Dirk, I ran across these solar links. I'm still in the educating myself mode. Anyone have any ideas on where I can find information on government subsidies/grants/etc... for putting up solar arrays on your roof? The cost look to be in the $20,000 range which is still too much for me, but with some grants I might take the plunge... http://www.solarpv.com/self_study.html http://www.solaraccess.com/salearnonline/default.asp Achieving Energy Independence - One Step... http://www.bpsolarex.com/4th-Commercial-Downloads.html
