Orix Corp held a ceremony to celebrate the completion of a mega-solar (large-scale solar) power plant that has an output power of about 2MW and was being constructed in Mitoyo City, Kagawa Prefecture, Japan, Oct 21, 2013.

A company wholly-owned by Orix will run the power plant, whose name is "Orix Mitoyo Mega-solar Power Plant." The plant was built on a site owned by Asahigaoka Sangyo (a firm based in Mitoyo City, Kagawa Prefecture). The site used to be a poultry farm. But when the poultry business was closed, its land category was changed from agricultural land to residential/miscellaneous land, leaving part of the site unused.

Takenaka Corp provided EPC (engineering, procurement and construction) services for the plant, which is the first mega-solar plant that Takenaka provided EPC services for in the Shikoku region. The solar panels and PV inverters of the plant were manufactured by Solar Frontier K.K. and Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC), respectively. The solar panel uses CIS-based solar cells.

Because the ground on the site was solid and flat, a mounting system with a concrete foundation was employed. The mounting system endures wind by using the weights of the solar panels and concrete.

Asahigaoka Sangyo is considering building another mega-solar power plant with an output power of about 2MW on a site adjacent to the site of the newly-built power plant. To build a solar power plant on a site that used to be an agricultural land, it is necessary to apply for a permit to change land category and obtain a permission. But it is no easy task.

The new mega-solar plant was built in a short period of time because Asahigaoka Sangyo had already changed the land category.
