Different roofing materials require different photovoltaic mounting systems
Photovoltaic mounting systems can be classified in various ways, and different roofing materials require different photovoltaic mounting systems.
- Photovoltaic Mounting System for Glazed Tile Roofs
Glazed tiles are made from soft and hard materials such as alkaline earth and purple sand, which are extruded, molded, and fired. These tiles are brittle and have poor load-bearing capacity. When installing mounting systems, specially designed main support components are typically fixed to the roof beneath the glazed tiles. These components support the main beams, crossbeams, and connecting plates, which are usually designed with multiple openings for flexibility and efficiency.
- Metal Roof Mounting System
Metal roofing is made from thin steel plates formed through cold pressing or cold rolling. Corrugated steel sheets have advantages such as being lightweight, high in strength, earthquake-resistant, fast to install, and aesthetically pleasing, making them a good building material for structural protection and flooring. When installing a photovoltaic system on a metal roof, the shape and load-bearing capacity of the metal roof must be fully considered to determine the appropriate mounting method.
- Photovoltaic Mounting System for Concrete Roofs
Concrete roof photovoltaic mounting systems generally use fixed-angle mounts, though flat layouts can also be used. This type of roof mounting method typically employs a concrete foundation and standardized fixed connectors, available in cast-in-place and prefabricated styles.
Cast-in-place rectangular concrete foundations are suitable for roofs in areas with low load-bearing capacity and high wind loads. Prefabricated rectangular concrete foundations are suitable for roofs in areas with low load-bearing capacity and low wind loads.
