Abstract: An inductive control valve using solar battery as a supplementary energy source mainly includes an amorphous silicon solar battery fixedly mounted on a casing of an inductive flushing valve or a main body of an inductive water faucet. Positive and negative lead-outs of the amorphous silicon solar battery are parallelly connected to positive and negative electrodes of a charging battery to form a parallel power supply. And, an output of the parallel power supply is further connected to a power input of a micro-power-consumption inductive controller. The solar battery not only provides driving power needed by the control valve, but also charges the charging battery.
