The Tokyo-based company's plant engineering unit, in cooperation with Mitsubishi UFJ Lease & Finance, constructed the plant on the grounds of a Nippon Kasei Chemical plant at the port of Onahama, just to the south of Iwaki, Fukushima prefecture.

Mitsubishi Electric's plant features 46,690 of the company’s 261W monocrystalline PV modules, which boast a conversion efficiency rate of 15.8%.

The installation is part of a broader project that includes another PV plant on the same site.
