1. There are too many obstacles in the place where the street lamp is installed, which leads to a decrease in the charging efficiency of the solar panel; for example, leaves, buildings, etc. block the light and affect the absorption of light energy.
2. There is a light source as a reference next to the solar panel, so that the charging voltage of the solar panel is above the photo-control voltage point, and the light cannot be turned on; for example: there are other street lights next to the solar street light. The solar panel of the street lamp detects the light source and mistakenly thinks it is daytime, and the controller will not let it turn on the light at this time.
3. Install the solar panel under the wires, tree branches, light poles or other shelters, resulting in a shadow on the solar panel during the day; because solar panels generally have multiple strings of cells, if a solar panel There are shadows on the cells in a string, and the shadows are relatively deep. If it is serious, this string is equivalent to an open circuit, and if the solar panel is multi-string and 1-parallel, this solar panel will not generate electricity.
4. The lights are installed on both sides, and the solar panels are tilted face to face; for the sake of aesthetics, the installer may install the solar panels in a symmetrical way, but if the orientation of one side is correct, then the other side must be wrong. On the wrong side, since the light cannot reach the solar panel directly, the charging efficiency will be reduced.
5. There is a problem with the angle adjustment of the solar panel, which leads to low charging efficiency of the solar panel; the correct angle adjustment of the solar panel must follow a simple principle: let the sunlight directly shine on the solar panel, so that the charging efficiency is the greatest. In different places, the inclination angle of the solar panel can refer to the local latitude. What is the latitude, the angle of the solar panel will be tilted horizontally. Therefore, for different latitudes and different road surfaces, the angle of the solar panel is quite critical.
6. Charging the solar panel indoors; some customers will install the solar lights in the parking shed to facilitate night parking, but at the same time install the solar panels in the shed, so 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 connection line of the solar panel at will; in some places, because the installation of the solar panel interferes too much, the solar panel and the light are simply separated by a long distance. The two-core wires bought on the market are connected to each other and that’s it. Because the quality of the general wires on the market is not very good, and the distance between the wires is very long, the wire loss is very large, so the charging efficiency will be greatly reduced, which will affect the lighting time.
8. The on-site personnel will not use the engineering remote control correctly, and the parameter setting error will cause the light to not turn on;
According to many on-site reports, some construction workers reported that they did not know the function of the remote control. In short, they pressed a button randomly and ignored it when the light was on. In fact, at this time, the parameters may have been set incorrectly, resulting in abnormal lighting.
