Yamahachi Shoji Co., Ltd. (Headquarters: Gamagori City, Aichi Prefecture, hereinafter "Yamahachi Shoji") has introduced a large-scale self-consumption solar power generation system at "Kraspo Gamagori" (Kashima-cho, Gamagori City, Aichi Prefecture), a shopping center it operates. The installation was carried out by Sala Energy Co., Ltd. (Headquarters: Toyohashi City, Aichi Prefecture), with the aim of reducing environmental impact and achieving sustainable business operations.
■ Effective Utilization of Rooftop Space with High-Efficiency Panels and Realization of Sustainable Facility Operation
In this initiative, 966 solar panels were installed utilizing the extensive rooftop space of Kraspo Gamagori. High-efficiency "N-type monocrystalline solar modules" manufactured by Exol, incorporating the latest technology, are used to efficiently generate energy. These panels exhibit less degradation over time compared to conventional panels and come with a 30-year long-term output warranty, ensuring a stable supply of clean energy for the future and realizing sustainable facility operation with an eye towards the next generation.
・System Capacity: 444.4kW (460W × 966 panels)
・Power Conditioner Output: 333.3kW (HUAWEI SUN2000-111KTL-NHMO × 3 units)
A total of 966 solar panels installed on the rooftop of Kraspo Gamagori.
■ Environmental Impact: 218 Tons of CO2 Reduction Annually and "Local Production for Local Consumption"
With the introduction of this facility, Kraspo Gamagori will become a more environmentally friendly facility based on renewable energy. According to simulations, approximately 525,116kWh of electricity is expected to be generated annually. A significant feature of this initiative is that about 98.7% of the generated electricity will be self-consumed, contributing to a reduction of 218.23 tons of CO2 emissions (equivalent to the annual CO2 emissions of approximately 80 general households). We will promote sustainable store operations as an effective initiative towards the decarbonization of the local community.
Expected to contribute to CO2 reduction equivalent to the annual emissions of approximately 80 general households.
■ Safety and Consideration for the Building: Non-Penetrating "Oki-Kiso" (Placed Foundation) Method
As a shopping center welcoming many customers, ensuring safety and long-term maintenance of the building were top priorities for the installation. As a result of consideration, the "X-3 (placed foundation frame for flat roofs)" provided by Universal Ecology Co., Ltd., which can be installed without drilling holes in the roof, was adopted.
・High Wind Resistance: Designed to withstand maximum instantaneous wind speeds of 96m/s.
・Reduced Building Load: Simple design reduces weight burden on the building and lowers the risk of roof leaks.
