Technical Field

The utility model relates to a solar energy utilizes technical field, concretely relates to solar photovoltaic board posture adjustment device.

Background

With the development of society, energy conservation and emission reduction become the concerns of people, solar energy is rapidly developed and applied as a new green energy source, and especially in remote areas where no power facility or power lines are difficult to reach, solar energy is of great importance for power generation.

Due to the movement of the sun relative to the earth, sunlight impinging on a fixed photovoltaic panel has different angles of incidence at different times of the day or at different times of the year. Such incident light reduces the collection efficiency of the solar panel and reduces the amount of electricity generated by the solar panel. Since the collected solar energy is proportional to the cosine angle, i.e. the angle between the incident angle of the sunlight and the vertical surface of the solar panel, the loss caused by this effect is known as cosine loss. To improve the efficiency of the collection of sunlight, the solar panel may use a tracking device to maintain it in a position near perpendicular to the incident sunlight. Theoretical research shows that the acceptance rate of energy is improved by 37.7% when the sun tracking is adopted compared with the energy acceptance rate when the sun tracking is not adopted.

The tracking device is usually an automatic mechanical arm, and the accuracy of tracking the sun is an important factor influencing the light-gathering efficiency. Tracking devices can be classified into single-axis tracking devices and two-axis tracking devices based on their mechanical properties. Because the single-axis tracking device can only realize the sun tracking in one direction generally, but can not automatically track the angle change of the sun in the east-west direction and the south-north direction at the same time, the solar photovoltaic panel has lower sunlight absorption efficiency. The two-axis tracking device can ensure that the solar photovoltaic panel can track the movement of sunlight with high precision all the year round, and obtains higher energy conversion efficiency.
