A framing system, also known as a racking system, is used to fix the solar modules to the roof or to mount the panels on the ground. Typically solar framing systems are constructed from anodized aluminum and stainless steel components and must conform to AS/NZ 1170 structural standards.
Modern systems use high quality engineered components that allow for a great variety of system configurations. This eliminates the custom cutting of materials and enables faster installations. Framing systems are designed to minimize the modification to existing roof materials and ensure the waterproof integrity and wind loading of the roof is maintained.
Meridian Solar does not install on asbestos or slate rooves
- Brackets that attach to the rafters or purlins of the roof.
- Tilt Legs to provide required tilt angle to the panels on flat roofs.
- Rails: that attach to the brackets (or tilt legs) and support the solar modules
- Clamps: to attach the solar modules to the rails
Metal roofs such as colour bond steel, are easiest to fix solar framing to, however an important consideration is to prevent a galvanic reaction between the dissimilar metals of the roofing material and the framing system. Corrosion can occur if these different metals come into contact with each other, so a rubber separation must be used to prevent this.
Some framing systems being sold in Australia do not meet AS/NZ 1170 standards. They may not be structurally sound and would certainly void any insurance claims if something were to happen to the system such as the panels blowing off the roof. The installer of the solar power system should be able to provide evidence of certification of the framing system
