PURPOSE:To reduce the reduction quantity of the generated electric power even after a solar battery paddle is exposed in a high temperature environment for a long period by installing a thermoelement for cooling the reverse surface of the base plate of the solar battery paddle on the reverse surface and installing a control part for feeding electric power into the thermoelement. CONSTITUTION:When the temperature of a solar battery element rises, the generated electric power reduces. Then, on the solar light S receiving surface side of a solar battery paddle 1, a prescribed number of solar battery elements 10 are fixed on a base plate 11. A necessary number of thermoelements 12 are arranged on the reverse surface of the base plate 11. An element utilizing the Peltier effect in which the temperature at one edge lowers and the temperature at the other edge rises when electric current flows in one direction is used as the thermoelement 12. When the peak electric power is necessary, the necessary electric power is supplied into the thermoelement 12, and when a control signal C for cooling the solar battery element 10 is sent into a control circuit 2, a prescribed electric current is sent as control signal into the thermoelement 12, and the thermoelement is cooled, and also the solar battery element 10 is indirectly cooled through the basic plate 11. |
