PURPOSE:To aim at the efficient utilization of generating output, by constituting the connection of plural blocks of a solar battery element group for vehicles so as to make it selectable to such connection as being suitable for each of purposes for battery charging, steady-state operation of a ventilating electric fan and starting the fan, respectively. CONSTITUTION:An output end of a solar battery element group 1 is set down to a charging circuit for a battery 6, and there is provided with a second select switch 8-2 which is selected to a circuit ranging from a solenoid on-off switch 4 to a motor 5 for driving a cab ventilating electric fan. In addition, there is provided with a first select switch 8-1 which is interlocked with selection of the switch 8-2 and selects connection of the element group 1 to series connection and series-parallel connection, constituting it as a manual operation switch 8 together with the switch 8-2. Also there are provided with third switches 11-1 and 11-2 which select the element group 1 to be driven by output of a timer relay 11 to be set with the close of the solenoid on-off switch 4 at a time when room temperature exceeds the specified value, to parallel connection. |
