This is 400 watts of solar panels on the rear shell. Not all of the mounting screws are installed in this photo. The frame is designed to put all of the weight on the side walls rather than than the roof. This will be joined by 3 more panels on the front shell, which brings the system to the maximum 150 volts open-circuit voltage handled by my MPPT solar charger. No, I don’t expect this to produce 700 watts! Rather, I expect 100 to 200 watts in partial shade, in the typical shaded campsite. The goal is to keep the batteries charged under the load of the electric refrigerator and all of the other typical RV loads. Or I could park this in full sun and run the ham radio at high power, without the generator.
