Mini Rail mounting system is a simple and cost-effective solution for trapezoid metal rooftop. Different from L-foot system and Clip lock system, the mini rail structure can stand without long rails crossing over the roof as the mini rail has 2 functions in one: one as base part to connect to the roof and 2 as the rail part to support PV panels.

L Feet are a type of mounting accessory used to attach solar panels to a rooftp or other surface directly or with some other products in between. The advantages of using Solar Mount Accessory L Feet include increased stability, improved safety, risen height and enhanced aesthetics to some extent.
