Tsuyama City is located in a basin in the northeast of Okayama Prefecture. It is known to be the largest city in the northern part of the prefecture and developed from a castle-town of the Tsuyama Domain. As you make a left turn on Izumo Road and pass under the Chugoku Expressway after driving for about 20 minutes from the downtown area, where Tsuyama Castle is located, tiers of solar panels will come into view.

3 types of mounting systems and panels of 5 manufacturers

This is the "Tsuyama Solar Village Power Plant," a mega- (large-scale) solar power plant with an output of about 1.3MW. Okayama-based construction company Shigeyamagumi Co Ltd (Bizen City, Okayama Prefecture) completed the power plant in September 2013 (Fig. 1).

Shigeyamagumi provides engineering, procurement and construction (EPC) services for solar power plants and manufactures and sells mounting systems, in addition to the construction business. This power plant plays a role as the company's solar power business showroom with three types of mounting systems and solar panels of five different manufacturers all set up in one place.

The site, which utilized a former tile plant, consists of four areas at different heights (altitudes) on both sides of a road. Foundations were set up on many areas, which had originally been covered by concrete, by making the best of their old paved surfaces.
