In December 2017, a solar power plant with an output of about 318kW started operation on "Onuma" reservoir in Ranzanmachi, Hiki-gun in central Saitama Prefecture, Japan (Fig. 1).

Surrounded by the Higashimatsuyama Plateau and Sotochichibu Mountains, Ranzanmachi historically boasts a farming industry while it also has a number of plants and logistics facilities reflecting its excellent access with the Kanetsu Expressway and its Ranzan Ogawa Exit.

Onuma can be referred to as a symbolic place of such an area. The Taiyo Holdings group's Taiyo Ink Mfg Co Ltd's head plant adjoins Onuma, an agricultural reservoir. This company is known as a leading manufacturer of "solder resist," an insulator material used in printed wiring boards.

Group company Taiyo Green Energy Co Ltd (Ranzanmachi) developed and runs the "Ranzan Onuma Floating Solar Power Plant," which started operation on Onuma.

Generated power is self-consumed at the adjoining Taiyo Ink Mfg's head plant.
