If you’re thinking of putting solar PV on your metal roof to generate renewable energy and save money over time, you’ve made a great choice. Metal roofs are an ideal platform for mounting solar modules thanks to their long service life and durability. 

There are two main approaches to attach solar modules: one uses rails; the other is rail-less. For solar rail installations, aluminum rails are secured to the roof and solar modules are attached to the rails to hold them in place. Rail-less systems attach components directly to the roof to support the solar modules. Each has its own unique aspects.

Rail solar roof mounting:

1、Drilling metal roof solar mounting method：solar corrugated metal roofing L foot clamp, By using rubber gasket under L foot base, it can prevent rain drops well .You can dip a little mastic on screw, it can also help as sealant when installing .This solar L bracket is developed for both residential and commercial corrugated metal rooftop mounts .These L feet clamps can support solar panels freely installed on even or sloping roofing.

2、Without drilling roof about solar roof mounting system method: Each of our kits utilize our non-penetrating roof clamps to help protect the roof panel from installation damage by eliminating the rotational force exerted on the panel by typical fixing screws. 

Rail-less solar roof mounting:

Our solar panel installation kit uses roof clamps to fix the panels to the seams of the metal roof panels. rail-less system helps to quickly install frame-type photovoltaic modules on the iron roof. Only one component is required to install the module directly on the roof. Easy-to-install clamps can be fixed to almost all tin roofs. The trackless installation system makes logistics, cost-effective warehousing and installation easy.
