When mounting on corrugated and sandwich roofs, you fix the photovoltaic installation directly to the purlins of the roof construction. For wooden purlins, you need the stock screw set for wood and for steel purlins the stock screw set for steel. These structures are typically made of steel or aluminum and must withstand wind, snow, and other environmental stresses. It's like buying a Ferrari but using bicycle tires. With an industry-leading 23% efficiency rating and an IP68 waterproof rating, EcoFlow"s rigid. . Thereby we have to introduce some solar panel support with Z profiles and purlins brackets,which are hot galvanized steel materialfor use in long time with better surface and the best cost during the system construction.
