Mitsubishi Estate·Simon Co Ltd (Chiyoda-ku, Tokyo) installed a carport-type solar power generation system (PV carport) with an output of about 1MW in part of the parking area on the premises of Shisui Premium Outlet, which the company runs in Shisui-machi (town), Chiba Prefecture, Japan.

Mitsubishi Estate·Simon started operation of the PV carport Dec 20, 2017. Orix Corp sold and arranged the carport.

About 4,200 cars can be parked in the parking area in total, and about 4,000 solar panels were set up in an area where about 500 cars can be parked. The PV carport is expected to generate 1,025,900kWh of electricity, which is equivalent to about 80% of the annual power consumption of the common-use space of the Shisui Premium Outlet, per year. All the electricity generated is consumed in house, and 541,500kg of CO2 is expected to be eliminated per year.

Nippon Comsys Corp provided construction services. The solar panel and PV inverter employed for the plant are products of Toshiba Energy Systems & Solutions Corp and Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC), respectively.

Mitsubishi Estate·Simon switched part of the electricity used at the Shisui Premium Outlet, Ami Premium Outlet (Ami-machi, Ibaraki Prefecture), Gotemba Premium Outlet (Gotemba City, Shizuoka Prefecture) and Sano Premium Outlet (Sano City, Tochigi Prefecture) to renewable energy in April 2016. Specifically, the company used renewable energy certificates and started to supply 8,000,000kWh of renewable energy-derived electricity. The PV carport is the second solar power generation system after the system installed at the Ami Premium Outlet (See related article).

In cooperation with Toyota Tsusho Facilities Corp (Nagoya City), Orix made Schletter GmbH's PV carport support Japan's Building Standards Act. Orix is proposing the introduction of the carport and providing engineering, construction and maintenance services for the carport. Also, as a solar power producer, Orix is promoting about 990MW of projects. It has so far sold about 850MW of solar power generation facilities to its customers.
