Use of solar light for dam cleaning 1999.04.15

The attempt to remove algae such as the Aoko using solar power generation started in April at Kokawauchi Dam in Lake Okutama. It is a mechanism that the electric power ship collects by two pumps installed on the surface of the lake, but the power of the pump uses a solar panel of 1.2 m * 0.8 m on a raft of 210 sheets on a lake surface (power generation capacity 25kw). Also on the deck of the electric power ship 1. 5 kw power generation device is installed.
