Fuji Sash Co Ltd announced that it has installed a mega (large-scale) solar power plant with an output capacity of 1,376kW on the roof of a storehouse and started power generation in March 2014.
Fuji Sash is a Japan-based firm that deals with housing and building materials. The storehouse is located on the site of the company's Chiba Office (Ichihara City, Chiba Prefecture), which faces Chiba Port.
The plant was built as parts of Fuji Sash's efforts to reduce CO2 emissions, which is described in the company's environmental policy. It generates the amount of electricity equivalent to that consumed by 360 households and eliminates 471t of CO2 emissions per year.
Omron Field Engineering Co Ltd provided EPC (engineering, procurement and construction) services. SunPower Corp and Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC) provided solar panels and PV inverters, respectively.
For the maintenance of the plant, Fuji Sash introduced a technology to detect abnormalities of panels for each connecting box. Because the plant is located in a coastal area, the company employed a panel that has passed a salt spray test (IEC61701, severity: 6).
