A condition of not permitting an increased temperature value of a diode (13) to exceed the junction temperature is satisfied by a simple structure at a low cost. A plurality of reverse current preventing diodes (13) between terminal plates (12) to which electrodes (a) of solar cell modules (M) are connected are connected in parallel. When an output current (I) from the solar cell module (M) flows in a circuit of the plurality of diodes (13) connected in parallel, a current (i) flowing in each diode (13) is reduced by a factor of the number of diodes connected in parallel, for instance, when the three diodes are connected in parallel, the current becomes one third. When the value of the flowing current is reduced, a heating value is also reduced. A heat dissipating piece (20) is provided on the terminal plate (12). In this way, the heat resistance reliability of the diode (13) can be maintained without using an expensive heat resistant diode, by sharing the load of the output current by the plurality of diodes (13) and efficiently dissipating heat from the terminal plate (12). ® KIPO & WIPO 2007 |
