Solar Powered Led Street Lights Problems and Solutions

The biggest difference between solar powered led street lights and traditional street lights is that solar powered led street lights rely on solar energy to supply electricity. As environmentally friendly and renewable energy, solar energy is widely used in many industries. Solar street light is one of the successful applications using solar energy. Solar powered street lights are mainly composed of solar panels, controllers, batteries, light sources and other parts. Solar street lamps are widely used in sparsely populated rural areas due to the easy maintenance and low maintenance cost. But there are still people who doubt whether the maintenance of solar led street lights is really that convenient? In this article, we mainly introduce some basic problems and solutions of solar powered led street lights.

1. The entire solar powered led street lights do not light up

Solar powered led street lights are used for outdoor lighting, so they usually encounter high temperature and rainy, low temperature weather and other environments. The solar street light controller is usually installed in the light pole. When it rains, it is easy for water to enter and cause the controller to short-circuit. We can first check whether there is a problem with the terminal of the controller. If the controller is damaged, check whether there is voltage and current output when the battery board is working normally. If there is no output, replace the battery board.

2. The solar led street light source is not bright

First check the quality of the LED light source and whether there is any problem with the false welding of the chips. Many solar powered led street lights use dot-matrix LED light sources. In addition to the quality of the LED light source itself, some weak welding of the chips will cause this situation. The solution is to replace the corresponding chips, weld firmly or replace the entire street lamp head. If not, it may be that the sunlight is insufficient at the installation location and the overall configuration of the lamps is not reasonable.

3. The lamp head flashes

This situation may be due to poor line contact, battery power loss, and serious decline in power storage. If there are no problems, the battery is broken and the battery needs to be replaced.

4. Short lighting time

If it is rainy, the light will last for a short time. Generally, it is caused by a decrease in the storage capacity of the battery and insufficient power of the battery. Just replace the battery.

5. Damaged solar panels

Test the open circuit voltage of the solar panel. The solar panel is not connected to any load in the sun, and do not connect to the controller. Pull out the wires of the solar panel directly and connect a multimeter to test its voltage. Under normal circumstances, the voltage of the solar panel will show higher than 12V. Only the voltage higher than 12V can it charge the battery. If it is lower than 12V, the battery cannot be charged. If the voltage of the solar panel is lower than 12V, the solar panel needs to be replaced.

In short, there are many reasons for the failure of solar powered led street lights. When the problem occurs, it must be investigated in time to understand the cause of the problem, so that the problem can be solved in a targeted manner. If you don’t know how to detect the problems, you can find a professional solar street light manufacturer, which can reduce the probability of secondary maintenance. In addition, we would like to remind everyone that when purchasing solar led street lamps, you must buy branded high-quality products, so that the probability of failure of the lights will be relatively low. Even if there is a failure, the solar street light supplier can provide good after-sales service.
