The Popular Rail for Roof and Ground Mounting Systems | Sic-solar.com

 Generally, the rails are Aluminum rail, and due to their shapes, they are used with different mid/end clamp and screw.

As below two rails, SIC-RA and SIC-R0 , both of them are used with SIC-IC/EC and tilt-in module.

And below two rails (SIC-R2 and SIC-R3)are used with SIC-IC-P which can be pressed into the rail directly and the hexagon bolt.

The two rails are rather popular in European market.

  Can   solar panels   be mounted on a metal roof? For sure, metal roof is one of the best roof material to install solar panels, due to its durability and easy for installation. Either framed or frameless solar panels could be mounted, and the shadows of panels could keep your home cool during the summer. The Metal roof have various types. The corrugated steel roof is the basic type, which you can see everywhere. To fix solar panels on it, the solar mounting brackets need to penetrate the roof sheet and fix into the wooden or steel beam directly by screws or hanger bolts. Details as follow. 1.  L feet+self-tapping screws 2.  L feet+Solar hanger bolt L feet is widely used for its high adaptability, which do not have request on the size of metal roof sheet. For some project, below alu clamp will be developed to better adapt with the corrugated steel roof. But it is not proposed due to its unique adaptability.

A brief introduction to the earthing washer/grounding clips in solar mounting system

  Grounding PV modules  to reduce or eliminate shock and fire hazards is necessary and required by Electrical Code in countries in USA, Australia etc. The grounding guidelines of the Code es sentially state that all electrical equipment is to be grounded by means of direct attachment to an equipment grounding conductor. This can be done in many different ways. The traditional method is to use the ground bond point of each  solar panel  and connect all the panels together with heavy gauge bare copper wire. This approach can be difficult, time-consuming and costly. Some of the difficulties in grounding PV modules arise from the fact that copper conductors are typically used for electrical connections while the module frames are generally made of aluminum. The incompatibility of copper and aluminum was discovered from numerous fires in houses wired with aluminum wiring in the 1970’s. Copper and aluminum will also react and corrode. The surfaces of aluminum frames are an...
