We are currently in southern New Mexico and can obtain about 5500 W-hours a day (on sunny days) this week and run the Dometic fridge from inverter/solar/battery bank during daylight hours and 24 hours a day if we know it will be sunny the next day as well. The primary problem with flat panels is that you get nothing until about 9:30 am, and similarly nothing much past 3:30 pm.
We could utilize another 700 W of solar. Just went on the roof with a piece of cardboard the same size (more or less) as one of our 235 W x 30 V panels and found that three more could be emplaced.
We were on Olympic Peninsula for three wees this summer and I called the Mora CG in Olympia National Park and inquired about a solar suitable spot. I was chided gently "Sir, this is a rain forest, your solar panels will not be of much use!" We spent a week at a National Forest CG near Beaver and were getting about 500 W-hrs each day in 150' trees. So, we were going down 750 or so W-hr a day. We had a 5 kW-hour deficit in the battery bank by the time we left. We had plenty of solar at a couple of Forest Service CGs on the Oregon Coast.
