Myself and an experienced carpenter friend mounted and installed the solar sheet a south facing wall of my home. The room I intended this solar sheet for already has existing gas heat (forced air) but this was to serve as supplemental heat. I installed it in october 2007.
Over all I am a bit dissapointed with the heat the unit produces - on the really cold crisp new england winter days that we have been getting with no clouds in the sky the panel operates for about 3 hours kicking on at about 10am and running until about 1pm (if i am lucky). I was expecting the room to be very warm and comfortable but the room does not get above 65 while the solar panel is operating . I am not sure if its the short time (3 hr run) it gets to operate and I am hoping with longer days (spring) it will generate more heat. Solar heat is a great idea but alas I am not thrilled. I am happy that I have reduced my carbon foot print slighty but its generally due to wearing thicker socks and sweaters when i'm home :-(
