"Ishinomaki Numazu Solar Power Plant," a mega (large-scale) solar power plant for which Juwi Shizen Energy Inc (Bunkyo-ku, Tokyo) provided EPC (engineering, procurement and construction) services, started commercial operation in Ishinomaki City, Miyagi Prefecture, Japan, Sept 1, 2017.

Juwi Shizen Energy made this announcement Jan 30, 2018.

The power producer of the plant is Ishinomaki Kizuna GK, a special purpose company wholly owned by GE Energy Financial Service, which is affiliated with General Electric Co. Trina Solar Japan Energy Co Ltd (Minato-ku, Tokyo), a subsidiary of Trina Solar Ltd, developed and managed the project. And Juwi Shizen Energy Operation Inc (Bunkyo-ku, Tokyo) is responsible for operation and maintenance of the plant.

By using about 220,000m2 of land that was formerly used as a golf course, about 14MW of solar panels were installed. The plant is expected to generate about 16,080,000kWh of electricity, which is equivalent to the amount consumed by 4,400 households, per year. Electricity generated at the plant is sold to Tohoku-Electric Power Co Inc at a price of ¥36/kWh based on the feed-in tariff (FIT) scheme.

The solar panel, PV inverter and mounting system employed for the plant are products of Trina Solar, Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC) and Schletter GmbH, respectively.

Through land reclamation work taking advantage of the terrain of the existing golf course, the area where solar panels can be installed was efficiently expanded. Also, a reservoir was built based on ordinances of Miyagi Prefecture.

With a large-size array consisting of four lines of (longitudinally-arranged) panels, the number of installable solar panels was increased, and the conversion efficiency was optimized. Roughly four kinds of arrays were employed, and they were set up in accordance with soil quality and terrain.
