Takara Leben Co Ltd, Hitachi Zosen Corp and Solar Frontier KK announced Dec 9, 2014, that they have started to build a solar power plant with an output of 15MW.

Takara Leben, as a power producer, will install 120,000 solar panels on the site of a former golf course (about 400,000m2) that the company owns in Nakagawa-machi, Nasu-gun, Tochigi Prefecture, Japan. The plant is expected to generate about 21,000,000kWh of electricity per year.

Takara Leben will introduce 750 units (15MW) of Delta Electronics Inc's 20kW PV inverter.

"It will be Japan's first mega (large-scale) solar power plant that is connected to an extra-high voltage power transmission line and uses distributed small-scale PV inverters," the company said.

In general, the area of each hole of a golf course is different from the areas of the other holes. As a result, the number of solar panels that can be installed in each hole differs from one another, making it difficult to efficiently arrange centralized PV inverters.
