In my shed I have 2 solar motion sensing led "security lights" - one in the main floor area and one in the attic. Makes it so I can see whatever U'm looking for. If I need to WORK in the shed I generally use my cordless tools but I also have a 12 guauge ext cord that I can run from the garage. If I need 220 I can fire up the generator I store in the shed (after moving it outside, of course) The solar lights have roughly 8 inch square solar panel each mounted to the south facing gabel of the roof.
