The amount of electricity produced by a solar panel depends on the size of the panel, the amount of sunlight the panel gets, and the efficiency of the solar cells inside the panel. To run the fridge overnight, my panels put in 49 A-hr at 24 volts nominal to run the fridge 24 hours or approximately 1.2 Kw-hr for a 24 hour day. The number of 160 watt panels required would be: 7824 watt-hrs/day / (160watts/panel x 5 hours sunlight per day) = 9.78 = 10 panels. Battery sizing for the Steca Solar Fridge.
