0landmanhallBest Answer 10 years ago ReplyUpvoteI had a small PV in a window for a week before they made me remove it. We arent allowed to have anything other than white blinds in our windows. Now I put it near the floor with the blinds open so it cant be seen from the outside. I have a few mirrors that reflect light into the hallway also. I save about ten or fifeteen bucks a month doing this. We have a strong crosswind when we open windows on oppisite sides of the apartment so I may try a small windmill too. (My box fan spins like crazy when its in the window and off) I dont believe the owners of the apartment will let you crawl on the roof and put holes in the roofing then run wiring to your apartment but you coud ask!
