1. There are too many obstructions in the place where the street light is installed, which reduces the charging efficiency of the solar panel; for example, leaves, buildings, etc. block the light, which affects the absorption of light energy. 2. There is a reference light source next to the solar panel, so that the charging voltage of the solar panel is above the light control voltage point, and the light cannot be turned on; for example: there are other street lights next to the
solar street light, when the night falls, the side street lights are on, resulting in The solar panel of solar street light detects the light source and mistakenly thinks it is daytime, and the controller will not turn it on at this time. 3. Install the solar panel under wires, branches, light poles or other obstructions, resulting in a shadow on the solar panel during the day; There are shadows on the cells of the string, and the shadows are relatively deep. If it is serious, the string is equivalent to an open circuit, and if the solar panel is connected in multiple strings and one in parallel, the solar panel will not generate electricity. 4. Install the lights on both sides, and the solar panels are inclined face-to-face; the installer may install the solar panels face-to-face symmetrically for aesthetics, but if one side is facing correctly, the other side must be wrong. On the wrong side, since there is no way for the light to reach the solar panel directly, the charging efficiency will be reduced. 5. There is a problem with the angle adjustment of the solar panel, resulting in low charging efficiency of the solar panel; the correct angle adjustment of the solar panel should follow a simple principle: let the sunlight directly hit the solar panel, so that the charging efficiency is the largest. In different places, the inclination angle of the solar panel can refer to the local latitude. The latitude is the horizontal inclination angle of the solar panel. Therefore, for different latitudes and different road surfaces, the angle of the solar panel is quite critical. 6. The solar panel is charged indoors; some customers will install the solar lamp in the parking shed to facilitate parking at night, but at the same time, the solar panel is also installed in the shed, so that the charging effect will be greatly reduced. In this case, we can use outdoor Charging, indoor discharge, solar panels and lamps are installed separately. 7. Extend the solar panel connection line at will; in some locations, because the installation of solar panels interferes too much, simply separate the solar panel and the lamp a long distance, and some customers separate it by a distance of 10 meters or even longer, and then randomly This is done by connecting two-core wires on the market. Because the quality of the general wire on the market itself is not very good, and the distance between the wire is very long, the wire loss is very large, so the charging efficiency will be greatly reduced, resulting in the impact of the lighting time 8. The on-site personnel will not use the engineering remote control correctly The remote controller, the parameter setting is wrong, and the light does not turn on; according to many on-site understandings, some construction workers feedback that they do not know the function and purpose of the remote control. In fact, at this time, the parameters may have been set incorrectly, resulting in abnormal lighting.
