Fixed Triangle Rack mounting system is a solar roof mounting system designed for those who want their solar brackets with some specific tilt angle to maximize sunlight exposure to PV panels. This mounting system can be installed on both metal roof and flat concrete rooftop. It’s easy to install and usually applied in cases to position quite a few PV panels. With main parts made of surface anodized aluminum AL6005/T5, the system can stand firm and keep a long life service.
