Solar mounting system

  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   Si gn   so lar  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, a...
