Photovoltaic support, as the name implies, is a shelf for fixing photovoltaic modules. It is mainly responsible for protecting photovoltaic modules from external factors such as strong winds. Therefore, sturdiness is an important product attribute. But in fact, this seemingly simple bracket also has room for upgrades.

The intensity of light directly determines the efficiency of the module. In order to maximize the power generation efficiency of the module, the traditional fixing bracket generally chooses an installation inclination to better absorb sunlight, and this inclination often chooses the angle with the strongest light intensity in a year. Usually this angle cannot be adjusted, or can only be adjusted manually according to the seasonal changes in light, which is time-consuming and laborious.

Although the traditional fixing bracket has chosen a seemingly angle, in fact the sun is changing in real time, and it is difficult for the components to fully absorb the light. The point of view is only relative. Most of the time, the power generation efficiency of photovoltaic modules is compromised.

In nature, sunflowers are named after their flowers always face the sun. Inspired by this, the industry began to introduce tracking brackets to solve the problem of components absorbing light. The tracking bracket can be adjusted by angle to track the movement of the sun in real time, so that the components always face the angle of sunlight, so as to improve the power generation efficiency.

Different from the simple structure of the fixed bracket, if the tracking bracket wants to realize the function of tracking sunlight in real time, it is necessary to add a drive system and a control system.

The control system is equivalent to the "brain" of the tracking bracket, which sends instructions to the drive system and controls the real-time orientation of the bracket. After the control system captures the "command", it needs to complete the adjustment of the direction and angle of the support.

The photovoltaic tracking bracket makes the bracket no longer a decoration, but a key link to improve the efficiency of the module.

According to the difference in structure, tracking brackets can be divided into two types: uniaxial and biaxial. A single axis can only rotate on one plane, and can be divided into a single flat axis and a single oblique axis according to the angle of the rotation axis, which can only make the inclination angle of the light as small as possible; the dual axis controls the direction and direction of the component respectively by two axes. The inclination angle always allows the components to absorb strong light.

Although the effect of the dual-axis tracking bracket is good, the bracket must be strong enough in addition to rotation. The current technology is not mature and the cost is high. In contrast, the single-axis tracking bracket is more cost-effective. It is a mature flat single-axis tracking bracket. On the basis of only increasing the investment by about 10, you can gain 25% of the efficiency improvement. It is the mainstream solution in the industry at present.
