A number of ponds are located next to one another in the rice field areas in Kato City in central Hyogo Prefecture, Japan (Fig. 1). They are all agricultural reservoirs that supply water to rice paddies in the Yado District, Kato City.

Fig. 1: Solar panels float on three of the reservoirs. The panels in the upper right reservoir are the floating part of the "Kato City Yado Solar Power Plant" while the panels in the two central reservoirs are the "Kato City Yado Oike Solar Power Plant." (source: Nippon Comsys)

Of those reservoirs, solar panels float on three of them, which are located next to each other. They are the "Kato City Yado Oike Solar Power Plant (Sun Lakes Yado Kato)" (capacity: about 2MW), where all the panels were set up on water, and the floating part (71.5kW) of the "Kato City Yado Solar Power Plant (Sun Factory Kawata Kato)" (capacity: about 1.3MW), which consists of both ground and water areas. Nippon Comsys Corp, which is engaged in telecom infrastructure, developed these power plants.

Nippon Comsys rented the reservoirs' surface from the local Yado community association, which manages the reservoirs, and set up the power generation facilities there.
