How Long Is the Service Life of Solar Street Lights?
Sep 21, 2024
As an important part of the urban lighting system, solar street lights have been widely used in roads, communities, parks, and other places due to their energy-saving, environmental protection, independent power supply, and other functions. When we choose to use solar street lights, a very important factor is how long we can use them. In fact, the service life of solar powered street lights depends on various factors, including component quality, maintenance methods, and environmental conditions. Solar street light suppliers understand that the service life of a well-designed and properly maintained solar street light can be maintained at an average of 10-20 years. Next, let's take a look at the service life of each component of solar street lights!
Solar panels generally have a long life, but their efficiency will gradually decrease. The photoelectric conversion efficiency of high-quality crystalline silicon solar panels decreases by about 0.5% to 1% per year. Therefore, after 20–25 years of use, the power generation capacity of solar panels may be reduced to about 80% of their initial level. However, in order to maintain this service life, it is necessary to keep the surface of the panel clean during normal use and avoid exposure to extreme temperature or humidity environments.
The battery is one of the key components of solar powered street lights, and its life is affected by the number of charge and discharge cycles. Lithium batteries usually have a longer lifespan than lead-acid batteries and are more resistant to high and low temperature environments. Ambient temperature, depth of discharge, daily use, and maintenance have a greater impact on battery life. Among them, the service life of ordinary lead-acid batteries is usually 3-5 years, while the service life of lithium batteries can reach 5-8 years.
As the lighting part of solar street lights, LED lights usually have a service life of 50,000 hours or more, which is equivalent to about 17 years of use when running 8 hours a day. The life of LED lamps in solar energy street lights mainly depends on the quality of the LED chip and the heat dissipation design of the lamp. If the heat dissipation of the lamp is not good, the life of the LED lamp may be greatly shortened.
High-quality LED lamps usually have very small light decay during their service life and can maintain good brightness.
The controller is responsible for managing the work of solar panels, batteries, and lamps to prevent overcharging or discharging. High-quality controllers are waterproof, dustproof, corrosion-resistant, and can adapt to extreme weather conditions. Its life is affected by the environment and usage conditions. The service life of the controller of solar street lights is generally 5-10 years.
The life of structural parts such as light poles and brackets mainly depends on the material (such as galvanized steel, stainless steel, aluminum alloy, etc.) and anti-corrosion treatment. Good-quality light poles can be used for 20 years or even longer under proper maintenance.

Through the above introduction, we can understand that due to the different lifespans of various components of solar street lights, solar street lights need to replace these components over time. Comprehensively considered, the overall service life of solar street lights can reach 15–25 years, which mainly depends on the quality and maintenance of the components. In order to extend the service life of solar powered street lights, we can take these measures:
1. Regular maintenance: Regularly inspect and maintain solar street lights outdoor, including cleaning solar panels, checking the charging and discharging of batteries, replacing aging components, etc.
2. Pay attention to the use environment: Try to avoid installing solar street lights under extreme climatic conditions to reduce the impact on the life of street lights.
3. Reasonable use: Avoid improper use such as long-term excessive discharge or charging and frequent switching of lamps to reduce damage to components such as batteries and controllers.
Solar street light manufacturers remind us that regular maintenance and inspection are essential to ensure the service life of solar energy street lights and maintain optimal performance. When we can perform correct maintenance according to the recommended methods and use high-quality components, we can extend the service life of solar street light outdoor as much as possible.
