The power generation amount of a PV device is estimated by multiple light receiving devices, which are dispersed in a predetermined area and each of which outputs a receive light signal corresponding to the amount of received light, and by an estimation device connected to the multiple light receiving devices through a communication network. The estimation device predicts the cloud shadow projected on the ground based on the received light signal obtained multiple times from a predetermined number of light receiving devices of the multiple light receiving devices. Then, the estimation device estimates the amount of power generated by the PV device installed in the predetermined area, based on the predicted cloud shadow. |
