The popularity of solar street lamps has brought a lot of convenience to our life, but long-term use will cause some problems of solar street lamps more or less. Below, we will make a detailed analysis of the six common problems of solar street lamps.
1. How to repair solar street lamps when they are not on?
Firstly, check the indicator light on the controller. If the battery indicator light is not on, check whether the connecting wire between the controller and the battery falls off. If it does not fall off, check the voltage of the battery. If the voltage is normal, replace the controller. Secondly, check whether the load indicator on the controller is on. If there is voltage output, it means normal. If there is no voltage output, the controller needs to be replaced.
2. Do solar panels need to face south?
China is located in the northern hemisphere. The sunlight is directly from the south, so only the solar panel facing south can fully absorb the solar light. If the solar panel facing north, it can not absorb the solar light. Therefore, in order to ensure daylighting, solar energy should make full use of light energy, make the best tilt design according to the local sunshine conditions, and ensure the maximization of power generation.
3. Are solar panels fragile?
The solar panel is not as delicate as we think. It is made of polycrystalline or single crystal cells. The surface layer is pressed with a fairly firm tempered glass layer, and the frame is firmly fixed, which can withstand the hail test. As long as it is not artificially damaged, solar panels will rarely be damaged.
4. How much electricity can solar street lamps produce?
With different configurations, the generated power and lighting duration will naturally be different. The configuration of solar street lamps is generally determined according to the local environment. Normally, when selecting solar street lamps, the parameters of solar street lamps will be configured according to the local actual situation.
5. What happens if the solar panel is shaded?
The solar panel shall be installed where the sun can be received all day. There shall be no tall trees and buildings around to shield the sun. Even if there is a small amount of shielding, it will greatly reduce the power output of the system.
6. Do we need to clean solar panels often?
Under normal circumstances, it is not necessary to wash the solar panels frequently, but it can also be determined according to the local conditions. In most areas, the solar panels can be cleaned through sufficient rainfall, while in areas with large wind and sand, they can be washed frequently in winter and less in summer. During the cleaning process, do not step on or stand on the solar panel, and do not wipe and clean with metal and hard objects.
