Hello... Since i did not get the house i planned, i now have 20 175 watt panels sitting in basement without any good use, i am hoping to have any chance to use them in somewhat supporting way... Can i set them up somehow (shady south facing environment), so that i gt at least what they harvest transported into the basement as heat? I might have space for 8-9 outside and i am not planing to grid tie or even buy any expensive equipment for this project... So would it be working to parallel them and put something (DC, any ideas) at it in basement for heat? Thx!!
