Why Solar Street Light Is Not Working?

Solar street lights are accepted by more and more people, and the market is getting bigger and bigger, gradually replacing traditional street lights. Because it saves energy and environmental protection, and saves manpower and material resources. Whether it is urban or rural areas, park schools or highways and other places, everyone is very fond of solar street lights. Especially in rural areas, especially the various facilities are relatively incomplete. It is easier for them to install solar powered street lights and save the villagers a lot of electricity bills. Sometimes, the installed solar road lights don't work. Why the solar street lights don't work? Let's get to know the reasons.

1. Check the controller

The controller is an important accessory to control the lighting of solar street lamps with motion sensors. If the solar street lamp is sometimes on and sometimes not on, or the on time is relatively short. Obviously because there is a problem with the controller, you can reconnect the controller. If the solar street light controller does not have any indicator lights, it indicates that the controller is malfunctioning, and a suitable controller must be repurchased. If you don't understand this aspect, you can find the manufacturer who bought the solar street lamp to buy the corresponding accessories.

2. Check the light source

High-quality solar street lights all use led light sources. The failure of solar powered street lights may be caused by the problem of the light source. The first thing to consider is the quality of the light source, and also whether the connection and welding of the lamp socket are firm. The configuration of the light source must be carried out in accordance with the actual supply of photovoltaic panels and batteries, and cannot exceed the load. You can also check whether the LED lamp beads have black spots. If there are black spots, you need to replace the LED light source. Generally speaking, we have to integrate various situations and eliminate them one by one. If the street lights were normal in the early stage, then we can consider whether it is due to weak light caused by seasonal factors and wiring problems caused by weather and temperature. The simplest solution is to change the light source directly. It is recommended that you choose the best light source for solar street lighting from regular and reliable manufacturer, so that the good working performance of the solar lamps can be guaranteed.

3. Is the installation scientific and correct?

The installation of solar street lights has requirements for the site, and it must be installed in a sunny place. If the solar panel cannot absorb enough sunlight, the converted electric energy will be very little, and the natural light will not turn on. Therefore, when choosing to install solar street lights, be sure to choose a place with plenty of sunlight and no obstructions around, so as to better charge the battery.

4. Check the battery

If there is a problem with the battery, such as reverse connection of the positive and negative poles, poor contact, and the end of the service life, the solar street light will not work and the voltage will be relatively low. It is necessary to check whether the positive and negative poles of the battery are connected reversely. You can also connect the battery directly to the load, test the voltage with a multimeter, and check the voltage change. If the voltage decreases, the battery is normal. If the solar street light is not on for enough time, you can reconnect the battery or directly replace the battery. There are three types of batteries, one is a lead-acid battery, and its service life is only about two years. The service life of gel batteries is relatively long, about three years. Nowadays, many solar powered street lights use lithium batteries, the longest service life can reach about 6 years. If you choose a lead-acid battery, it may be damaged after one or two years, which will shorten the lighting time of the street lamp and cause the failure of not lighting.

5. Line problems

After long-term use of solar street lights, there may be problems with the circuit. Mainly manifested as poor line contact, or battery power loss, which will cause the battery's energy storage to drop. The decrease in the energy storage of the battery will cause the lights to flicker constantly and the brightness is not enough. If this happens, you should promptly investigate the problem of line aging, damage or poor contact.

The above several situations may cause the solar street lamp to not light up, but it is not ruled out that it is caused by other faults. The maintenance personnel should check one by one, and the correct solution can be obtained after finding the cause of the failure. The chance of high-quality solar street lights not turning on is very small. As long as they are installed scientifically and used correctly, they will have a long service life. So we need to buy solar street lights from large and capable manufacturers. Shenzhen EXC-LED Technology Co., Ltd was established in 2009, with more than 2,000 employees. It is a national high-tech company integrating LED application products and cloud control system design, R&D, production, sales and service. EXC dedicated to providing street lights(General), solar street lights, LED street lights, smart street lights, tunnel lights, garden lights and control systems.
