LG panels, TMEIC PV inverters adopted

At ESR Kuki DC with a rooftop solar panel capacity of 2.39MW and a PV inverter rated capacity of 1.89MW, power generation is expected to amount to 2,700,000kWh per year. All generated power is sold at 21 yen/kWh using the FIT scheme.

Solar panels (315W/unit) manufactured by LG Electronics Inc of South Korea and PV inverters (1MW/unit) made by Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC) were adopted (Fig. 5 & 6).

Kinden Corp provided engineering, procurement and construction (EPC) services while Cool Earth Co Ltd (Chiyoda-ku, Tokyo) of the Advantec Co Ltd (Chiyoda-ku, Tokyo) Group operates and maintains the plant.

According to ESR, setting up solar panels on the roof of this logistics facility was not a problem in terms of load resistance. What ESR aimed for while designing the power plant was "to keep the wiring route and incidental equipment from entering the tenant space and to enable the solar plant to start operation as soon as the building is completed by finishing assembling the solar power generation facility within the construction period of the building itself," said Satoshi Takeda, senior director and head of construction at ESR.

In fact, these goals set at the beginning of the design phase were successfully achieved (Fig. 7).
