I think you missed the part about black rubber livestock bowls.
Yeah, you can easily set up for solar with car battery. CFL don't draw much power if you wanted to supplement light in winter and there really is only a few days out of winter you'd enjoy a heated dog bowl so wouldn't need much power. 20W panel would do it. Believe you can get an inexpensive one with internal controller to not overcharge the battery for around 50 bucks. Then all you need is 12v to 110 converter.
thanks for the info everyone! any ideas on a water heater I could power by solar? Or maybe a car battery?
