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.
Bracket type/Bracket performance | Aluminum alloy bracket | steel frame | non-metallic bracket |
Anti-corrosion properties | Generally use anodic oxidation (>15um): aluminum can form a protective film in the air, no anti-corrosion performance is required for later use: good anti-corrosion performance | Generally,hot dipgalvanizing isused(>65um,anticorrosion maintenance is required in later use, and the anti-corrosion performance is poor) | |
Mechanical strength | The deformation of aluminum alloy profiles is about 2.9 times that of steel | The strength of steel is about 1.5 times that of aluminum alloy | |
material weight | About 2.71g/㎡ | About 7.85/㎡ | |
material price | aluminum alloy profiles is about three times that of steel | ||
Applicable items | Household roof power stations with load-bearing requirements: industrial factory roof power stations with corrosion resistance requirements | Power stations that require strength in areas with strong winds and relatively large spans |
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.
