PU CHIN Technology, in response to global warming, decides to construct a 499-kilowatt roof-mounted solar system through a partnership with Taiwan Distribution Center Co., Ltd. High efficiency 290W monocrystalline solar modules are deployed, covering large area of the roof and thus reducing temperature at the top floor drastically. Reduced energy demand for the air conditioning system is consequently achieved and energy saving fulfilled. Mounting structure is made corrosion resistant by anodization and in conformity with national building code, wind load capacity is up to 27.5m/s, a force equivalent to Beaufort scale 10.
