The great thing about many solar products is that they don't require any electrical outlets or wiring. You can literally put them anywhere where there's sun.
Solar powered fans are a good example. I know someone who installed a solar powered vent fan in his doghouse, which didn't have electricity.
Simply cut a hole, install the fan, and let it do its thing.
You can install solar powered fans in garages, storage sheds, campers, cabins, or boats. (Boats are a good place because lots of moisture builds up, which turns to mold and mildrew). And solar powered fans run strongest when they're needed the most--when the hot sun it out!
