The structural adhesive and double-sided tape recommended by DAS Solar have high adhesive force. They’ve passed the internal test and assessment. In a wind-tunnel test performed by the China Academy of Aerospace Aerodynamics Technology, force 14 wind was used to blow the binding position between the module and the installation surface. The module remained in place without power attenuation or obvious cracking on the EL. As for the weather resistance of adhesive property, DAS Solar has passed reliability tests for high temperature, high humidity and salt spray. Even amid such harsh tests, its adhesive force can still meet the requirements. This guarantees its long-term outdoor service.
