We saw many users on the Internet saying that solar street lights did not achieve their expected effects, the lights would not light up for a while, and the lighting time for a while was not as long as expected, etc. Today, LIXIN will popularize the installation of solar street lights for everyone. question bar:
1. The solar panel is installed under other shelters, resulting in a shadow on the solar panel during the day;
Because solar panels generally have multiple strings of cells, if there is a shadow on a certain string of cells in the solar panel, and the shadow is relatively deep, if it is serious, this string is equivalent to an open circuit, and if the solar panel is multiple If it is connected in parallel, this solar panel will not generate electricity.
2. Because there are too many obstacles in the place where the street lamp is installed, the charging effect of the solar panel is greatly reduced: for example, leaves, buildings, etc. block the light and affect the absorption of light energy.
3. 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 light control voltage point, and the light cannot be turned on.
For example: there are other street lights next to the solar street light, and when night falls, the street light next to it is turned on, causing the solar panel of the solar street light to detect the light source and mistakenly think it is daytime, and the controller will not let it turn on the light at this time.
4 .Lights installed on both sides, solar panels tilted face to face;
For the sake of aesthetics, the installer may install the solar panels face-to-face in a tilted and symmetrical manner, 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. 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.
6. Extend the connection line of the solar panel at will;
In some locations, because the installation of solar panels interferes too much, the solar panel and the light are simply separated by a long distance, and some customers are separated by a distance of more than 10 meters or even longer, and then they buy two-core wires on the market to connect them. 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.
7. 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 needs to follow a simple principle: let the sunlight shine directly 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.
