Solar flat panel has advantages of high collector efficiency, powerful safety and reliability, long using time

Solar flat panel

adopts full-copper core board. It has performance of high pressure resistance, and testing pressure is at 0.9Mpa. Using ultrasonic welding, it could reduce thermal resistance at the most and keep absorption efficieny. Heat absorber adopts high performance heat-absorb coating, and its efficiency could reach as high as 95%. Tempered glass is used as cover, with high heat preservation effect and transparency.
