The "Nasushiobara City Solar Power Plant (Sun Factory Sekiya Nasushiobara)," a mega- (large-scale) solar power plant with an output of about 5.7MW, is situated inside Sekiya Industrial Park in Nasushiobara City, Tochigi Prefecture, Japan (Fig. 1). It started operation in July 2016.

The Nippon Comsys Group, which is primarily engaged in telecom infrastructure, developed and operates the plant. The power producer is its group company Comsys Create Corp (Shinagawa-ku, Tokyo). Nippon Comsys Corp provided engineering, procurement and construction (EPC) services.

This is the Nippon Comsys Group's 12th solar power plant (See related article 1, 2). The investment totaled about ¥1.71 billion (approx US$16.9 million).

Sekiya Industrial Park, where the power plant is located, is surrounded by forests and rice/vegetable fields in Shimotano and Sekiya, Nasushiobara City. It was developed on two adjoining sites that had been a former factory and an unused site. The project consists of two power plants with an output of 2.87MW, respectively. A total of 21,648 solar panels were set up on about 106,000m2 land combining the two sites.

Solar panels of Kyocera Corp and PV inverters of Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC) were adopted.

There is another power generation site with a 2.9MW solar power plant being constructed. It is scheduled to be completed in March 2017.
