摘要： A solar cell array control device has a plurality of solar cell modules, a bidirectional DC converter, at least a voltage sensor and a control unit. The bidirectional DC converter corresponds to and is electrically connected to the solar cell modules to connect these solar cell modules in series to form a solar cell array. The voltage sensor is electrically connected to the solar cell modules, and can generate an abnormal voltage when detecting that one of the solar cell modules is abnormal. The control unit is electrically connected to the voltage sensor and the bidirectional DC converter, and outputs a pulse width modulation signal by detecting the abnormal voltage to control the bidirectional DC converter for compensating the conversion current and thus enhancing the output power of this solar cell module.
