What are the types of photovoltaic power stations?

Photovoltaic bracket refers to the specific geographical location, climate and solar resource conditions of photovoltaic power generation system construction, and the photovoltaic module is arranged in a certain direction and angle, and the support structure with fixed spacing is fixed.

As an important part of the photovoltaic power generation system, the photovoltaic bracket directly affects the operational safety, damage rate and construction investment of the photovoltaic module. Choosing the right photovoltaic bracket can not only reduce the project price, but also reduce the health cost in the later stage. One of the main considerations is climate tolerance. The solar power station has a robust and reliable structure during its 25-year life cycle, guaranteeing that it can withstand environmental erosion and wind and snow loads. In addition, considering the safety and reliability of the installation, better use results can be achieved with minimal installation costs. In addition, whether maintenance can be waived in the later stage, whether there is a reliable maintenance guarantee, and whether the stent can be recovered after the end of the life cycle are also important factors that need to be considered. The general photovoltaic bracket is divided into fixed type, tilt angle adjustment type, automatic tracking type three types.

1. The fixed bracket is also known as the fixed inclination bracket, after the installation of the bracket, the inclination angle and orientation of the assembly cannot be adjusted. The fixed bracket is divided into several parts, such as roof class, ground class, water surface class and so on.

2, the structure of the tilt variable bracket is similar to the fixed bracket, more than the fixed bracket one more adjustment mechanism, can manually adjust the tilt angle of the bracket, the adjustment mechanism has a hierarchical type and continuous variable type, the segmented type is generally set to 2 to 3 levels, adjusted 2 to 3 times a year. The continuously variable form can be adjusted at any time. To facilitate adjustment of the tilt angle, there are not many components mounted on a single bracket. Typically, the number of installed components fits into one or two group columns. The inclined angle variable bracket has push rod type, circular arc type, jack type, hydraulic rod type and so on.

3. The automatic tracking bracket can always maintain the solar power generation unit perpendicular to the sunlight, eliminate the cosine loss of the fixed power station, accept more solar power generation units, and increase the power generation. The automatic tracking bracket is divided into single-axis tracking and dual-axis tracking, and its common point is that the surface normal of the photovoltaic equation is moved accordingly according to the rules of solar motion, reducing the incidence angle of sunlight. Through automatic tracking, on the one hand, the utilization rate of solar radiation energy can be improved, and the conversion efficiency of the power generation system can be improved. On the other hand, when obtaining the same amount of power generation, the use of photovoltaic modules can be reduced and the construction cost of the system can be reduced.
