Solar LED street lights have been widely implemented. Solar street lights are an excellent product in terms of energy-saving, low carbon, and environmental protection. At the same time, because they rely on solar power generation, the project cost will be relatively reduced. Then some users will ask us if they use solar street lights for a period of time. It reflects that the solar street light does not light up after installation, or it can only light up for a few hours. So why is this? Today I will take everyone to explore the reasons for this.
The main reason for this situation is that the construction personnel do not fully understand the installation requirements of solar street lights, which makes the installation method of solar street lights improper, which causes the solar panels to be unable to charge normally and causes the solar street lights to fail to light or to light up for a very long time. So what are the misunderstandings about the installation of solar street lights?
1. There is no obstruction around the solar street lamp installation site. Once the obstruction blocks the light, it will easily affect the light energy absorption and utilization of the solar panel, causing the solar panel to be directly unable to charge or barely charge a little.
2. The installation of solar street lights is too dense. There are other street lights next to the solar street lights. Other street lights are on, causing the solar street light board to detect the light source and mistakenly think it is the sun, which causes the charging voltage of the solar panel to take effect, and the light naturally does not It will light up.
3. The solar panel is under the shadow of the obstruction, which leaves a shadow on the solar panel and cannot directly receive the sunlight source because the solar panel cells are generally in strings, and a shadow on a string of cells will Even if this string of cells can't work normally, this string is disconnected, so the charging efficiency of the solar panel is very low or it may not be able to charge even the battery.
4. Double-arm solar street light. The double-arm solar street light must be connected to solar power for both lamp holders. If both solar panels are connected to the power source and are installed face-to-face and inclined, then only one side of the solar panel is effective. Yes, on the other side, because the light source can't directly shine on the solar panel, the charging efficiency will be reduced.
