The absorption of solar energy makes it difficult to increase power generation efficiency.

 [0003] In the prior art, some use time control devices or light control devices to control the solar panel to rotate in accordance with the rotation of the earth, but the time control is only similar to the rotation law of the earth, and does not truly track the direction of the sun; The control device is more susceptible to weather or dark clouds and cannot accurately track the direction of the sun, thus failing to truly track the direction of the sun, allowing the sun to be incident near the solar panel.

 [0004] Some concentrating solar power plants use a large number of mirrors to collect and focus sunlight onto a solar panel, or use a focusing lens to focus sunlight onto a solar panel to improve lighting efficiency. However, the drawback of using these methods is that at the sun's rays, the temperature can reach 890 degrees Celsius or even thousands of degrees Celsius. Solar panels often burn because of excessive energy.

[0007] Further, the solar power station further includes a resetting device disposed in the base station for controlling the solar panel to quickly return to the starting position, that is, the position where the sunlight can be received in the morning. Confirmation [0008] Further, the solar panel is a parabolic arc surface that approximates the shape of the earth surface, and its north-south direction forms an elevation angle e with the sun.

 [0009] Further, the two support rods are provided with hydraulic transmission adjusting devices, and are connected with the solar panels.
