Introduction to several photovoltaic power stations

With the continuous development of the new energy industry, the types of power generation units in the photovoltaic power station have developed from the initial simplicity to the current diversification. The following is an introduction to various power generation unit modules used in the photovoltaic power station.

(1) Fixed single crystal module power generation unit

The fixed single crystal module power generation unit (Fig. 323) is installed with buried fixed support. According to the area where the power station is located and the local sunshine radiation, the best component inclination angle is calculated to maximize the solar radiation received by its components and the solar radiation received by the plane.

(2) Fixed amorphous silicon thin film module power generation unit

The principle of the fixed amorphous silicon thin film module power generation unit is consistent with that of the above fixed monocrystalline silicon module power generation unit, but the components used have changed.

(3) Flat single axis photovoltaic module power generation unit

There is no difference between the modules used in the flat uniaxial photovoltaic module power generation unit and the fixed power generation unit. It is characterized in that the modules installed in the flat uniaxial module power generation unit are on the same plane, and an axis that can rotate freely about 270 ° is installed on the support, so that it can follow the sun from east to west according to the change of solar radiation angle in the area where the person is written in the program, Make the solar radiation received by its components and the solar radiation received by the plane reach the maximum, so as to improve the power generation of the components.

(4) Inclined single axis photovoltaic module power generation unit

Installation principle of inclined single axis photovoltaic module power generation unit and flat single axis photovoltaic module power generation unit

The installation principle is consistent. The difference is that the installed components are not in the same plane, but are fixed on the support according to the calculated specified angle according to the component inclination angle calculated by the local solar radiation, and then rotate from east to west according to the change of solar radiation angle through the shaft installed on the support, The sunshine resources of solar energy are used more effectively.

(5) High power concentrating power generation unit

The high power concentrating power generation unit mainly uses the principle of convex lens to concentrate the sunlight on the installation

Gallium arsenide on the component to generate electric energy. In order to make full use of light resources, 360 ° rotation tracking high-power concentrating power generation unit is adopted.

(6) Double axis tracking power generation unit

The power generation principle adopted by the double axis tracking power generation unit is basically the same as that of the fixed power generation unit

The difference is that the two axis tracking power generation unit can change the inclination angle of the component and the orientation of the component facing the sun through the transmission of two motors, so that the component installed on it can track it in real time according to the radiation angle and sunshine orientation of the sun.
