Solar power is highly dependent on local conditions like weather, season, and latitude. One cannot assume getting a full charge every day in every condition. | Solar power is highly dependent on local conditions like weather, season, and latitude.

To account for this decide how many reserve days of power you need if there is little [[https://www.wholesalesolar.com/solar-information/sun-hours-us-map|solar power available]].

It is safest and simplest for solar newbies to assume a day of poor solar harvest = zero solar harvest. In actuality zero harvest is highly unlikely; more experienced or risk-tolerant RVers can run with [[electrical:solar:slim reserve|less reserve or no reserve at all]]. | It is safest and simplest for solar newbies to assume a day of poor solar harvest = zero solar harvest.
