Alabamadan, I have two 55 watt modules and one 110 watt module with a total of 144 solar panels, which has a charging potential of approx. 13 amps to the battery banks. I have a 13" color TV, home alarm system with auto dial, DVD, VCR, water pumps, small microwave, small refrigerator, 4000 watt inverter, fan, ceiling fan, lots of compact flouresent lights among other things. Works great, and I do not have to pay anyone a bill. I have around $1200.00 in the solar system which was cheaper than the power company wanted to run poles and power to my cabin and the fight I was having trying to get an easement from the neighbor who lives in another state. I bought cosmetic blemished panels which saved me alot. After a night of using lights, TV etc. which only depletes the battery bank around 20% the battery bank is usually charged back up by 9:30AM.
