I am planning to make solar panels Backyard Revolution that can fit inside a 16″x24″ container for easy storage and portability. My plan calls for 3 solar panels with 12, 3×6 solar cells each. The cells and the panels will all be wired in series. This should give me an 18 volt system, which should be enough to charge a 12 volt deep cycle battery. The battery will be the most expensive part of the whole build, costing about $150 dollars. In this plan I am not going to use multiple batteries since it will not be necessary to power up only a few electrical accessories that I would take with me camping. If you were going to power up your RV or camper you might have to consider adding several batteries to supply both the needed amps and watts for your appliances.
