With the widespread use of solar LED street lights around the world, the lifespan of these lights is a major concern for users. Questions about which components are prone to issues, how often the batteries need to be replaced, and other related concerns are common among customers. So, what is the actual lifespan of solar LED street lights? Let us provide you with the answers.
Solar LED street lights are an independent self-generating lighting system that does not rely on grid electricity. During the day, solar panels convert sunlight into electrical energy and store it in batteries. At night, the stored energy powers the light source, creating a typical smart system of generation and discharge. The key component for this functionality is the solar panel, which is primarily made from pure silicon and has a lifespan of at least 20 years. Additionally, the LED light source lasts over 50,000 hours, with normal usage extending beyond a decade.
Next, we have the solar batteries. The commonly used solar maintenance-free batteries in the country have a normal lifespan of 5 to 8 years. Under regular use conditions, batteries typically need replacement every 3 to 5 years. It is important to note that larger manufacturers produce batteries with a longer lifespan, whereas smaller companies may provide batteries with shorter life spans. Over a period of 3 to 5 years, the actual capacity of the battery may significantly decline compared to its original capacity, but the cost of replacing a battery is not excessively high, making replacement straightforward.

The solar controller is relatively inexpensive, around a hundred dollars, and has a lifespan of about 5 years. As for the lamp post, most companies provide hot-dipped galvanized and powder-coated posts, which typically last about 20 years without damage.
The longevity of solar LED street lights is primarily reliant on the batteries. Therefore, it is essential to choose a battery with a sufficient capacity when purchasing solar street lights. It is crucial to understand that the lifespan of a battery is defined by its cycle discharge duration, which typically allows for about 400 to 700 complete discharges. If the battery capacity aligns only with daily discharge levels, it may easily suffer damage. However, if the battery capacity is several times greater than the daily discharge, it extends the lifespan significantly, allowing for sustained illumination even over multiple cloudy days.
To further extend the lifespan of solar LED street lights, necessary maintenance is also vital. During the initial installation, it is essential to strictly follow construction standards and installation manuals. Ensuring reasonable configuration while increasingly the battery capacity will help prolong the lifespan of solar LED street lights.
