I almost fell over when I read this, it's great! When I first talked to my wife about going solar {we'd seen a few episodes of Living With Ed by then}, she was more than happy for me to build a solar array......as long as I did not put it on the roof. She said she was afraid I'd want to climb up there to clean them {I would} and she knew at some point I'd fall off the roof.

I adjust the tilt twice a year and wash them then. Other times, if I notice they are dirty, I rinse them.....
