Detailed summary of photovoltaic bracket types

1. Classification by material
Aluminum alloy bracket:
Features: light weight, corrosion resistance, beautiful and generous, but the price is relatively high.
Applicable scenarios: Suitable for scenarios with certain requirements for weight and aesthetics, such as photovoltaic systems in humid environments such as seaside.
Steel bracket:
Features: high strength, strong bearing capacity, corrosion resistance, but heavy weight.
Applicable scenarios: widely used in photovoltaic power station systems of various sizes, especially ground photovoltaic power stations and large roof photovoltaic systems.
Plastic bracket:
Features: low price, easy installation, strong weather resistance, but small bearing capacity.
Applicable scenarios: suitable for small-scale photovoltaic systems with high cost requirements.
Zinc aluminum magnesium bracket:
Features: high strength, corrosion resistance, long life, reusable, and good wind and earthquake resistance.
Applicable scenarios: suitable for photovoltaic systems under various environmental conditions, especially those requiring high corrosion resistance and wind and earthquake resistance.

2. Classification by structural form
Fixed bracket:
Features: The installation angle is generally fixed and unchanged, determined according to the local latitude and climatic conditions.
Subdivision types:
Roof brackets: including color steel plate roof brackets, sloping roof brackets, flat roof brackets and BIPV photovoltaic building integrated brackets, etc.
Ground brackets: including single column brackets, double column brackets and single ground column brackets, etc.
Surface brackets: including floating brackets, column brackets and offshore photovoltaic brackets, etc.
Applicable scenarios: widely used in ground photovoltaic power generation systems, large roof photovoltaic systems and water surface photovoltaic systems.
Adjustable brackets:
Features: The inclination angle of the bracket can be adjusted by manual or electric devices to adapt to different lighting conditions and energy requirements.
Subdivision types: push-pull rod type, arc type, jack type and hydraulic rod type, etc.
Applicable scenarios: suitable for occasions that need to adapt to seasonal changes or different energy requirements.
Tracking brackets:
Features: It can automatically adjust the angle and direction of the photovoltaic module according to the position of the sun to maximize the energy generation efficiency.
Subdivision types: flat single-axis tracking bracket, inclined single-axis tracking bracket and dual-axis tracking bracket.
Applicable scenarios: Suitable for large photovoltaic power stations, centralized solar power generation systems and places with high requirements for power generation efficiency.
3. Classification by installation method
Bolt-fixed bracket: The bracket is fixed to the foundation by bolts.
Ballasted bracket: The bracket is fixed to the foundation by ballast (such as stones, concrete blocks, etc.).
4. Classification by load-bearing capacity
Photovoltaic brackets can also be divided into small, medium and large according to load-bearing capacity to meet the needs of photovoltaic systems of different sizes.
