Study on the Optimal Orientation of Solar Panels

Study on the Optimal Orientation of Solar Panels

At present, most of the solar panels installed on the solar traffic light generally face the problem of being wrong. This shows the lack of a scientific, easy to use orientation method for installing solar panels.

After measuring the orientation data of the solar panel on the spot and photographing and analyzing many photos, I proposed using two kinds of schemes of "director" or "directional ruler" to help determine the installation direction of the solar panel. In order to improve the utilization of solar energy , Providing a scientific and easy way.

Second, the research process

(1) Through the field measurement, take photos and analyze the installation orientation of solar panels (such as solar cells and solar water heater lighting panels) currently widely used.

(2) Study the best orientation of the solar panels in the northern hemisphere and the angle of deviation of the sun (ie, the angle between the sun and the vertical center line of the solar panel). As shown in the following table, when the tilt angle of the solar panel is 26 degrees, the total amount of sunshine obtained during the year is the highest, and the deviation angle of the sun is not more than 23.5 degrees in summer and winter, and the solar panel is in the best working condition. When the tilt angle of the solar panel is 0 degree, the deviation of the sunlight in winter is larger and the illumination is insufficient. When the tilt angle of the solar panel is 67 degrees, the deviation angles of sunlight in spring, summer and autumn are large, and the light is the least in summer. Winter get the most sunlight, working conditions are not normal.
