Photovoltaic Power Generation System at Fuji Xerox Ebina Factory
Winner
Fuji Xerox Co., Ltd.
Kajima Corp.

Features of Equipment, Systems and Facilities

PV power generation system of 100kW capacity is installed on the factory roof.
The horizontal installation in compliance with the roof geometry allowed installing 4 time as much power output per unit area in comparison to the conventional installation.
The roof-integrated system used strong aluminum metal frame and waterproof function, and reduced the installation cost by 30 %.

  • Horizontal installation
    The horizontal installation allows reducing the construction cost and effective utilization of limited area of factory roof, in comparison to the conventional tilted installation. The power generation is kept high in summer when the solar altitude is high, contributing to coping with the peak demand for grid power.

  • Harmonious design
    The horizontal installation allows the PV power generation modules to be integrated to the factory roof without disrupting the exterior design, which may be readily approved by architects and designers. This concept will trigger large scale spread of PV power generation systems in many factories and warehouses.

  • Environment-friendly Construction Works
    Efforts are paid to moderate impacts of construction works to the environment, and reusable containers are used for transporting building materials.
