Title: SOLAR CELL MODULE ERROR DETERMINATION SYSTEM AND METHOD
Abstract:
An error determination system for a solar cell module including a plurality of solar cells connected in series comprises: a modulated light emission unit which emits modulated light to one solar cell of the plurality of the solar cells; a phase detection unit which outputs a signal corresponding to the state of the one solar cell on the basis of a signal indicating the power output of the solar cell module and a reference signal indicating the phase (frequency) of the modulated light; and a determination unit which determines whether or not an error has occurred in the one solar cell on the basis of the signal output by the phase detection unit.
