Solar rooftop mounting structure
China solar rooftop mounting structure
Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV).
Owing to the structure of the modules themselves, they are required to be mounted on another structure. This allows the modules to be held firmly to the surface of installation, capable of battling strong winds that could, without the careful design of the mounting structures, damage the entire installation. Additionally, in order to raise the overall efficiency and generation capabilities of the installation, a tilt is afforded to the modules of the system based on the geographical location and the positioning of the area of the installation. Now, to achieve higher levels of generation, the optimum tilt of the modules is achieved by raising the modules on a mounting structure. Based on the cost and customer requirements, a tracker may be used in ground mount installations as well, in order to allow for the tracking of the sun’s movement across the sky, and thereby, adapt the optimum tilt of the modules.
Mounting structures at times are built independently of a roof or ground installation. Pole mounts and carports are examples of mounting structures created such that the entire installation is raised several feet into the air, thereby keeping the installation independent of the conventional ground or roof mount solar systems.
