We are running our trailer on 100% solar power, we run everything in the camper and our tv/dvd, laptop, charging station, kitchen appliances, etc.. Everything except the a/c. So far a good few hours of sunlight on the two rooftop panels has charged up the batteries with plenty of power to spare everyday.

Two 100 watt Renogy Panels I got in a kit from ebay that includes two more panels I can put out in the sun if necessary. These are mounted to the roof of the camper.

Two six volt Rolls Surrette deep cycle flooded lead acid batteries I got from Dave at Staab battery in Springfield, IL. I think they are 220 amp hour

Here are the batteries all strapped in, they just fit on the stock battery shelf.

Here is the charge controller from Renogy also in the kit and a 12vdc to 110vac inverter.
