Talking about how to design the installation angle of solar street light battery panel solar street l

When installing solar street light, many people do not know how to determine the angle of the solar panel and which direction is appropriate. When installed, the solar panels are always facing due south, and the angle is basically the same as the local latitude. The solar panel is generally placed on the top of the light stand, and the connecting wires are all routed through the tube and all walk inside the light pole. (1) The inclination angle is at noon. In order to make the sun shine on the solar panel vertically, there must be an angle between the solar panel and the horizontal plane during installation. Usually, the angle between the solar panel and the horizontal plane is the inclination angle, which is measured in terms of metric. . When the total amount of solar radiation received on the inclined plane reaches the maximum, it is called the optimal inclination angle. The figure below shows the relationship between the solar panel and the ground. According to geometric principles, in order to make the sun shine on the solar panel vertically, the inclination angle of the solar panel should be calculated as follows: Inclination angle u003d 90° - altitude angle (elevation angle) Because the earth orbits at a certain inclination angle, the sun is at noon at noon. The angle above the horizon has a periodic change every year, and the above equation shows that a reasonable panel inclination should vary with the height of the sun. (2) Determine the inclination of the square array In order to maximize the ability of the solar panel to receive sunlight, the inclination of the panel should be equal to the latitude of the site. The average sunlight intensity projected on the solar panel is highest when the inclination angle is equal to the latitude. In addition, in order to take into account the periodic change of the sun's altitude angle, the inclination of the solar panel also needs to track the change of the sun's altitude angle, which is not only technically difficult but also very expensive. There are also some customers who place the solar street light's solar panel horizontally for the sake of appearance. In this case, the output power of the solar panel will be reduced by 15%-20%, and then a decorative cover is added on the solar cell. The output power will be reduced by about 5%. This greatly reduces the efficiency of the battery panel and affects the use of the entire solar street light. Here, we strongly recommend that users do not use horizontal placement.
