Packaged solar cell apparatus

摘要

A packaged solar cell apparatus comprises at least two sunlight electric generating devices, a light intensity detector for producing an output signal in response to the intensity of incident sunlight, a comparator for comparing an output signal level of the light intensity detector with a reference level, and a switch for automatically switching the connection of the plurality of sunlight electric generating devices in accordance with an output signal of the comparator. The connection of the plurality of sunlight electric generating devices is switched between series and parallel connections, respectively, as the output signal level of the light intensity detector becomes higher or lower than the reference level, whereby output electric power from the plurality of sunlight electric generating devices is efficiently supplied to a desired electric load in accordance with the intensity of insolation.
