PROBLEM TO BE SOLVED: To provide a sunlight power generation system, capable of corresponding even to an existing system and capable of accurately deciding the presence of snow coverage, while being able to melt snow by using power at low cost. SOLUTION: A solar-cell module 1 and a power conditioner 8 are installed to the system. A connection box 2 having a changeover means 6 is mounted further. The changeover means 6 changes over connection with the solar-cell module 1 of a power generation section 3, outputting a DC power generated by the solar-cell module 1 to the power conditioner 8, a snow-melting section 4 supplying the solar-cell module 1 with power for melting snow and heat- generating the solar-cell module 1, a snow-fall/snow-melting detecting section 5 detecting the states of the snow face and snow melting of the solar-cell module 1, and either one of the power generation section 3, the snow-melting section 4 or the snow-coverage/snow-melting detecting section 5. |
