Why is the higher the latitude, the greater the inclination of solar ground mounting structure?

May 25, 2022

As we all know, the light receiving surface is maximized when the plane of the object is perfectly perpendicular to the light. If the object is tilted, the plane of the object and the light will have an angle, and the power received will be relatively reduced. Therefore, when designing solar ground mounting structure, we should try to make the angle of the solar panel mounting structure perpendicular to the sun, so as to obtain the best power generation. But in the south, the mounting structure for solar panels is installed at a low angle. The higher the latitude, the greater the angle of installation.

Why not install it flat to get the best power generation? Because the diameter of the sun is 109 times the diameter of the earth. Therefore, it can be considered that the sunlight on the earth is direct. But the earth is not a plane, but a huge sphere. Close to the equator, it can be considered that the sun is directly shining, so the solar modules can be installed horizontally. In high latitudes, the sun is not in the center at noon, as people see it, but has a certain angle. The higher the latitude, the greater the angle. In order to obtain the best power generation, the mounting structure for solar panels is designed with a tilt angle.

The most ideal tilt angle is to make the solar cell's annual power generation as large as possible. If you don't know how to choose the best angle, you only need to provide the latitude and longitude of the project location, and Corigy's engineer can use the software to calculate the best inclination angle of the solar mounting structure.
