<p><P>PROBLEM TO BE SOLVED: To supply output electric power which is stable and sufficient to a load mounted on a vehicle. <P>SOLUTION: A solar cell system includes: a solar cell 10 having a plurality of output blocks 11 and 11; a storage battery 60 and another load 70; a connection switching portion 20 switching connection among the solar cell 10, and the storage battery 60 and the another load 70; and a controller portion 80 performing switching control in the connection switching portion 20. Further, the solar cell system includes: a temperature detection portion 50 which detects atmosphere temperature of the solar cell 10; and a voltage detection portion 40 which detects the voltage of the storage battery 60. When it is determined, based on the detection result of the voltage detection portion 40, that the output voltage of the storage battery 60 has a first voltage value, the controller portion 80 controls the connection switching portion 20 based on the detected temperature of the temperature detection portion 50 to switch the plurality of output blocks 11 and 11 to either a series connection or parallel connection. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
