What is a solar mounting system for solar photovoltaic panels?

A solar mounting system is a specialized support designed to place, install, and secure solar panels in a solar photovoltaic power generation system. Common materials used for these systems include aluminum alloy, carbon steel, and stainless steel. As a manufacturer of solar photovoltaic brackets, FIRSTSOLAR primarily uses aluminum alloy and carbon steel in our products. Those with inquiries can contact FIRSTSOLAR directly by phone.

What are the components and classification of solar

 mounting system？

1. Bracket

A system for supporting photovoltaic cell modules. It is composed of columns, 

supports, beams, axis，shafts,rails and accessories made of metal materials. 

In order to track the trajectory of the sun, it may also be equipped

 with transmission and control components.
2. Fixed bracket

Brackets with non-adjustable inclination and azimuth angles.
3. Single axis tracking bracket
A mount that rotates around an axis to track the sun.
4. Two-axis tracking bracket
A mount that rotates around two axes to track the sun.
5. Column
Components connected to the foundation for supporting beams, shafts, guide rails, etc.
6. Support
Components used to strengthen the stability of columns, beams and guide rails.
7. Beam
Components used to support rails.
8.Axis
Parts used to support the guide rail and adjust the angle of the guide rail 

(suitable for tracking brackets).
9. rail
Components used to support photovoltaic power generation components.
10. Connecting rod
It is used for mechanical transmission parts between the bracket and the power

 system (suitable for photovoltaic tracking brackets).
11. Accessories
Refers to the parts used for the connection between straight sections,

 between straight sections and bends to form the necessary connection 

and fixation of a continuous photovoltaic support system or to supplement 

the functions of straight sections and bends. 

The accessories of the bracket are divided into: 

straight line connecting plate, hinge connecting plate, 

turning connecting plate, variable angle connecting plate, 

partition, pressing plate, fasteners.

Classification of photovoltaic support

The classification of solar photovoltaic support can be mainly

 distinguished according to the material and installation method 

of photovoltaic support.
1. According to the classification of solar photovoltaic bracket materials:
According to the different materials used for the main stress-bearing members of the photovoltaic support, it can be divided into 

aluminum alloy support, steel support and non-metal support. 

Among them, nonmetal support is less used, 

while aluminum alloy support and steel support have their own characteristics.

2.Classification according to the installation method of solar photovoltaic brackets can be divided mainly into fixed and tracking photovoltaic supports. There are also more detailed classifications corresponding to each type, as shown in the following test.
