Automatic sun-chasing method for photovoltaic panel power generation

Abstract

The invention relates to an automatic sun-chasing method for photovoltaic panel power generation, which comprises the following steps: S1, a preset program drives an electromagnetic valve a to be opened, so that compressed gas flows into a deflection angle adjusting mechanism; S2, an air pump a receives compressed air and drives an adjusting component a to operate, a mounting shaft rotates, the deflection angle of the solar panel is changed, and when the deflection angle of the solar panel reaches a preset value, the preset program drives an electromagnetic valve a to be closed; s3, the preset program drives an electromagnetic valve b to be opened, so that compressed gas flows into an elevation angle adjusting mechanism; s4, an air pump b receives the compressed air and drives a rotating shaft to rotate, so that the elevation angles of the mounting frame and the solar panel are changed, and when the elevation angle of the solar panel reaches a preset value, a preset program drives an electromagnetic valve b to be closed; and S5, in severe weather, a worker manually controls a sun-chasing device to drive the rotating shaft and the mounting shaft to rotate, so that the elevation angle and the deflection angle of the solar panel are adjusted until the preset value for minimizing the influence of the severe weather on the solar panel is reached.

[0002] The traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more prominent. Therefore, the use of new energy sources such as wind energy, ocean energy, and solar energy to generate electricity has become an important topic of current research. The focus of attention, abundant solar energy is an important energy, inexhaustible, inexhaustible, pollution-free, cheap, so solar power is also known as the most ideal new energy, with permanence, cleanliness and flexibility, etc. etc., the current existing solar power generation technology generally fixedly installs the solar panels facing south and up, the purpose of this installation is to make the sun’s rays face the solar panels directly when the sun’s rays reach the maximum intensity at noon, but in this way There are also certain defects in the installation. The solar panels and the sun's rays cannot always be directly facing each other, especially during sunrise and sunset. The capture efficiency drops sharply. In order to solve the above defects, the present invention proposes an automatic day-by-day method for photovoltaic panel power generation. The present invention drives the rotating shaft to rotate through the elevation angle adjustment mechanism to change the elevation angle of the mounting frame, and drives the installation shaft through the deflection angle adjustment mechanism. Rotate to deflect the solar panel, that is, the deflection angle of the solar panel changes. In addition, the preset program is adjusted in advance according to the changing law of the sunlight irradiation angle in each place and season, and the elevation angle adjustment mechanism and deflection angle are controlled according to the preset program. The adjustment mechanism operates accordingly, so that the solar panel can face the sun, that is, the sun's rays are perpendicular to the solar panel, and the power generation effect can reach the maximum
