How To Choose a Photovoltaic Bracket?

Photovoltaic bracket, also known as solar panel bracket, is a structural system used to install and fix solar panels (also known as photovoltaic modules or photovoltaic panels).

Its main function is to place the photovoltaic panel in a suitable position and ensure its stable and safe operation, while achieving the best light receiving angle to maximize the conversion efficiency of solar energy.

Photovoltaic bracket is an important part of the solar photovoltaic system. It not only provides stable support for photovoltaic panels, but also maximizes the efficiency of solar energy reception by adjusting the angle of photovoltaic panels.

1. Support and fixation

(1) Support function: The photovoltaic bracket provides stable support for the photovoltaic panel to ensure that it will not fall off or tilt due to wind, snow load or other environmental factors.

(2) Fixation function: The photovoltaic bracket fixes the photovoltaic panel in a predetermined position so that it will not move or shake, thereby ensuring its stability and safety.

(3) Angle adjustment: The photovoltaic bracket can adjust the tilt angle of the photovoltaic panel to adapt to different lighting conditions, thereby maximizing the efficiency of solar energy reception.

2. Adjustment

(1) Adjustment range: The photovoltaic bracket can adjust the tilt angle of the photovoltaic panel within a certain range to adapt to changes in lighting in different seasons and at different times of the day.

(2) Adjustment mechanism: The photovoltaic bracket adjusts the tilt angle of the photovoltaic panel through mechanical devices or sensors to achieve automatic tracking or manual adjustment.

(3)Adjustment accuracy: The higher the adjustment accuracy of the photovoltaic bracket, the more accurately it can adapt to changes in lighting conditions, thereby improving the efficiency of solar energy reception.

1.Fixed brackets

(1) Advantages

The simplest structure, the lowest cost, suitable for areas with relatively stable lighting conditions.

(2) Disadvantages

Unable to track the movement of the sun, and may not be able to fully utilize the solar radiation throughout the year.

(3) Applicable scenarios

Applicable to areas with relatively stable lighting conditions, such as areas above 40 degrees north latitude.

2. Single-axis tracking bracket

(1) Advantages

Can rotate around one axis to track the east-west movement of the sun, improving the power generation efficiency of photovoltaic panels.

(2) Disadvantages

The cost is relatively high and the structure is more complex than that of fixed brackets.

(3) Applicable scenarios

Applicable to areas with more complex lighting conditions, such as areas above 30 degrees north latitude.

3. Dual-axis tracking bracket

(1) Advantages

It can rotate around two axes, not only can it track the east-west movement of the sun, but it can also adjust the tilt angle of the photovoltaic panel to match the change in the height of the sun. Although it has the highest power generation efficiency, it is also the most expensive and has a relatively complex structure.

(2) Disadvantages

It has a high cost, a complex structure, and requires more maintenance and management.

(3) Applicable scenarios

It is suitable for areas with complex lighting conditions and the need to maximize solar energy reception.

4. Inclined bracket

(1) Advantages

A fixed inclination angle is set during installation, which is suitable for areas with relatively stable lighting conditions. Its cost is low, but the power generation efficiency may be slightly lower than that of the tracking bracket.

(2) Applicable scenarios

It is suitable for areas with relatively stable lighting conditions, such as areas above 40 degrees north latitude.
