PURPOSE:To detect the output of a solar cell with high accuracy and facilitate the standardization of a circuit, to get the timing related to the quantity of insolation at sunset, sunrise, or the like, concerning the method and circuit for detecting the output of the solar cell. CONSTITUTION:When detecting the output of a solar battery PV, the output of a solar cell is detected by connecting a semiconductor diode D2 in forward direction to that solar cell PV, and detecting the forward voltage Vf of the semiconductor diode D2. |
