- Its state-level solar estimates apply a 0.8 derate for RV mounting losses and warn that local parking conditions can differ.
Field notes
The sizing flow separates running power and surge demand, then estimates battery capacity from daily watt-hour use. For solar output, it uses selected-state peak sun hours and applies a 0.8 derate for shading, angle, dust, and wiring losses. The page attributes its state averages to NREL PVWatts v8 / NSRDB data compiled by thegreenwatt.com, while cautioning that a specific parking spot may differ.
