CIRCUIT FOR SOLAR CELL ARRAY

摘要

A circuit for a solar cell array formed from clusters of serially connected photovoltaic cells that switch the output from a cluster to an output line depending on the level of illumination experienced by the cluster. The level of illumination may be detected by a photodetector or it may be estimated directly from each cluster by a current monitor circuit. The output from the cluster is switched to a highpower current line when the cluster experiences full or near full illumination or a low power current line when the cluster experiences below near full illumination. The switching level is determined relative to a threshold.
