Happy Service (Monbetsu City, Hokkaido), which operates sales agencies that sell mobile phones, etc, had a ceremony to celebrate the completion of a solar power plant with an output of about 1.5MW in Monbetsu City, Hokkaido, Japan, in December 2017.

The mega (large-scale) solar power plant is scheduled to start to sell electricity Jan 2, 2018.

Happy Service also sells Sharp Corp's solar power generation systems as an agency. It develops and runs mega solar plants using Sharp's solar panels in areas surrounding Monbetsu City (See related article). With the new plant, the total capacity of Happy Service's completed solar power plants became about 5.1MW.

The latest mega solar plant is located in Shinsei, Monbetsu City. The area of the site is about 45,000m2, and it was purchased by Happy Service.

The total capacity of solar panels installed at the plant is about 1.561MW, and the plant transmits 1.5MW of electricity to a power grid. The FIT tariff set for the project is ¥36/kWh (excluding tax). The plant is expected to generate about 1,250,000kWh of electricity, which is equivalent to the amount consumed by 340 households, per year.

Sharp provided EPC (engineering, procurement and construction) services, and a local company installed the solar power generation facilities.

For the plant, about 5,460 solar panels (output: 285W each) manufactured by Sharp were set up. Happy Service employed new solar panels designed for heavy-snow regions such as Hokkaido.

In the case of conventional solar panels, when snow piles up on them, the height difference between the aluminum frame (the periphery of panel) and glass cover prevents snow from sliding off onto the ground. This time, Happy Service used panels whose effect of preventing snow from sliding off is smaller.

Also, two units of Toshiba Mitsubishi-Electric Industrial Systems Corp's (TMEIC) 500kW PV inverter were installed for the plant.
