A quick way to find out the fault of solar street lamp

The basic principle of solar street lights is relatively primitive, which is a process of absorbing and releasing energy. Solar panels store light energy during the day and convert it into electrical energy. At night, the battery releases energy to power the lamp holder. Repeat this process every day. If the solar street light fails, such as the light bulb lighting time becomes shorter, the light bulb cannot be turned on, how can we quickly find out the cause of the failure?


First of all, we need to know whether the lighting time of solar street lights is short or not. If the lighting time is short, it means that there is a problem with the configuration of the solar lamp or the voltage of the battery panel is insufficient. The reason may be that the unreasonable configuration of the lamp is relatively small, or there may be a thick layer of dust attached to the battery panel. It is more common in riverside areas. In winter, the lighting time of the lamp is very short, and the continuous cloudy days are short. In this case, wipe the battery board for cleaning, and deal with it according to the degree of adhesion.
The second fault is that it does not turn on, the light does not turn on, and the situation is more concentrated on the controller is broken or the battery is broken. The LED street light lamp holder is damaged and the battery board is less damaged. If the controller has a problem, we use the investigation method Voltmeter to measure the voltage of the battery panel. If the battery voltage is higher than V during the sunny day, it means that there is no problem with the battery panel. If the battery voltage is higher than v, it means that the battery is normal, and we can consider replacing it with a new controller to check. After replacement, it can be illuminated in one or two natural days. This is a problem with the controller. Generally, the situation that the battery board and the battery are not lit is relatively small. If we measure the battery voltage to be lower than v during the day, then we need to check whether the battery wiring is well connected. If the wiring is intact, the solar panel voltage is still very low, which may be a problem with the solar panel, but most of the cases are concentrated on the battery. If the battery voltage is lower than v, the first option is that the controller has a fault that causes the battery to be insufficiently discharged and cannot be filled in time. Secondly, the quality of the battery is poor, and long-term use will cause excessive internal charging and discharging.


In short, if the solar street light does not light up, we should consider replacing the controller. If we find that the bulb has not been turned on for a long time, we recommend replacing the battery (if it is not turned on for a long time, the battery is probably damaged).
