At present, there are 3 types of brackets used in most PV power plants: fixed conventional bracket, adjustable tracking bracket and flexible PV bracket. This refers to the mounting system where the orientation, angle, etc. remain unchanged after installation.
The choice of bracket directly affects the operational safety, breakage rate and construction investment of PV modules. Choosing the right PV bracket will not only reduce the project cost, but also reduce the post maintenance cost.
The installation angle of PV modules in flexible mounts is generally small, usually 10°-15°. Flexible bracket is mainly applicable to scenarios such as mountainous projects with large slope (e.g. above 35°), fishery-photovoltaic and agricultural-photovoltaic projects with high headroom requirements.
PV flexible racking is a kind of large-span PV module support structure fixed at both ends and formed by pre-stressed flexible cable structure. The span of the cable structure is usually between 20 and 40 meters, up to 100 meters.
Flat single-axis tracking bracket refers to the bracket form that can track the rotation of the sun around a horizontal axis, usually with the axial direction of north-south. The common tracking angle range is ±60°, and there are also products with a tracking angle range of ±45°.
