1) After wide research of the domestic and abroad solar market, combing the characteristics of Chinese and foreign products, Sunrain Group creates a new type of flat panel solar collector by itself.

2) It adopts aluminum portfolio with 1 mm thickness for the frame, and copper-aluminum composite as the heat absorption core embedded in the aluminum frame, lying on 35 mm thickness glass fiber layer. The cover is made of 3.0 mm thickness toughened glass, and the sealing material is made of high quality EPDN.

3) The special module installation system is easy to mount on both flat and sloped roof, realizing the perfect integration between buildings and collectors, also meeting the demand of heat absorption.
