Let's look at a simple 12x12 room as an example.First we need to calculate the power consumption.  Remember, these are ROUGH estimates:(1) Ceiling fan, 10 hrs per day: 75 watts @ 10 hrs = 750Wh(6) 8W LED bulbs, 4 hrs per day: 48 watts @ 4 hrs = 192Wh(2) USB devices charging, 2 hrs per day: 20 watts @ 2 hrs = 40WhTotal per day = 982WhIf you have adequate sun for 10hrs per day, you should be able to get by with a single 100W solar panel. (=1,000Wh) If you have a lot of wind, as a backup, we would recommend...
