Which is better solution for metal roof solar mounting structure , rail or railless solution | Artsignenergy.com

 Metal roof is widely applied in factory and residential house, no matter it’s corrugated metal roofs, standing seam metal roof or trapezoidal metal roof, it’s a great idea to put solar panel mounting equipment onto it to generate energy.




Art Sign solar provides various solar mounting solutions for metal roofs.


Mainly devided into two big solutions, one is with solar mounting rails solution, and the other is railless solution. With rail solution, it normally attached with L bracket into metal roof and for railless solution, we have penetration solution and non-penetration solution for choice.


Why there’s rail and railless solution, which one is better?
Rail solution usually used with L brackets or roof solar hooks. compared with railless solution,  rail solution can be withstand bigger wind load and snow load.But it sure will with higher costs too.
Rail solution is with more materials and thus it’s heavier, and requires more time and labour to do installation.
Besides, if you have a metal flat roof and want to have solar modules with best angle to get more sun power, rail solution tilting is possible. Railless solar mounting design solution is impossible to tilt.
No matter which solar mounting brackets you choose, we will have professional and customized solutions to meet your needs.

  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...
