IDEC Corp and the government of Sayo-chou, Hyogo Prefecture, have completed a 5MW solar power plant in Sayo-chou.

It uses 20,160 solar panels, each of which measures 1 x 1.7m, and mounting systems made of wood (Japanese cypress) produced in Japan. The expected amount of electricity generated at the plant is 5,330,000kWh per year. IDEC and the government will start selling electricity to The Kansai Electric Power Co Inc Nov 10, 2014.

For the mounting system, square timers measuring 10.5cm x 10.5cm x 4m (or 3m) each are arranged in parallel crosses. Solar panels are mounted on it and fixed with metal fittings. And it is then mounted on foundations consisting of concrete and blocks. Because the panels function as a roof, rain does not directly hit the mounting system, preventing corrosion.
