Sunforson has devoted a lot of time to develop the waterproof mounting system. Our BIPV mount adopts 2 rails with EPDM pad surrounded all the edge of the solar panel for waterproof. The main rain is in vertical side for most rail falling and the support rail is in horizontal side for rain going for water-proof.
We have both solution for framed and frameless panels. Currently ,it is integrated with carport mounting frame and roof for waterproof.Below project photo for reference.
If you have project in demand of waterproof mount solution,welcome to consult our BIPV mounting brackets.
