Solar street lamps are great lighting solutions for streets, roads, highways,etc. Clean, eco-friendly, environmentally friendly and they don't rely on the electricity to power the light. They can not only provide illumination but also beautify the city. But how long do solar street lamps last? This is a question that most people concerned about.High performance solar street lamps can last 8-10 years if properly taken care of. If you want to invest solar powered street lamps, you have to figure out this question and we will provide some useful tips for your reference.

Solar street lamps are composed of controllers, solar panels, batteries, light sources and other components. To know how long do solar powered street lamps last, we have to consider LED chip, controller, solar cell and battery. At present, the lifespan of LED chip is generally around 50,000 hours, the lifespan of solar panel is more than 20 years, and the lifespan of controller is average. It is also more than 10 years. As long as it is used correctly in accordance with the instructions, there will be no problems with the controller. The main consideration is the service life of the LED light source and the battery. The service life of the battery is the key to the service life of the street lamp. Generally, the service life of a lead-acid battery is 2-4 years, and the service life of a lithium battery is 4-8 years. Depending on the manufacturer's materials, the quality of the accessories used by different solar street lamp manufacturers must be different. As long as the solar street lamps are reasonably configured, the service life can reach 8-10 years. Therefore, the service life of solar street lamps can still meet the requirements of use in many places. Solar street lamps use solar energy as the power supply to provide night road lighting. As long as the sun is sufficient, the lights can be turned on.

Useful tips to make solar street lamps last longer

In case of severe weather such as hail and heavy snow, we must find ways to protect the accessories. If the accessories are damaged, replace them in time. After bad weather, check whether the solar street lamp panel has moved or loosened. Also check whether there is water in the controller and the battery box. If water enters, please drain water in time.

Solar powered street lamps need to produce enough electricity when there is light. If the solar panel is blocked, the solar street lamp can't absorb sunlight normally. Therefore, when installing solar panels, choose the installation angle and position. The solar panels should face the sunlight, and there should be no obstructions such as green plants near the street lights. The surface of the solar panel should be kept clean. If there is dust or other dirt, first rinse with clean water, and then gently wipe the water stains with a clean gauze. Do not wash and test with hard objects or corrosive solvents.

Reasonably configure storage batteries and solar panels. The theoretical number of charge and discharge of lithium battery is about 800 times, the discharge voltage is relatively stable, and there is a dedicated protection chip, so the charge and discharge protection circuit is easy to implement. Therefore, it is recommended to choose a cost-effective lithium battery. It is recommended to increase the battery capacity by at least 15%, one is to ensure the discharge time, and the other is to not affect the overall capacity. Amorphous silicon solar panels have advantages in bad lighting situations, but the disadvantage is that they decay quickly and the conversion efficiency is about 12%. The conversion efficiency of monocrystalline silicon and polycrystalline silicon is about 17%. You can choose the solar panel that suits you according to your needs.

Reasonable configuration and well maintenance of solar street lamps will make the solar powered street lamps last longer.
