The lifespan of solar street light is approximately between 5 and 10 years, but the specific lifespan will vary depending on the service life of each component. Solar street lights are mainly composed of solar panels, LED light sources, batteries, controllers, light poles and other components. The life of each component will affect the overall service life.
Solar panels: Solar panels are one of the core components of solar street lights. Their lifespan is usually long and can reach about 20 to 25 years, but this needs to be achieved under the premise of normal use and regular maintenance.
LED light source: LED light source has the characteristics of high brightness, low power consumption and long life. Theoretically, the lifespan of an LED light source can reach more than 50,000 hours. If used for 10 hours a day, its lifespan will be at least 10 years.
Battery: The battery is one of the most critical components in solar street light, and its service life directly affects the overall life of the street light. Common batteries include gel maintenance-free batteries and lithium batteries. The service life of gel batteries is generally about 5 to 8years, while the service life of lithium batteries may be about 3 to 5 years.
Controller: The life of the controller is generally about 5 to 10 years. It is an important component in the solar street light system responsible for controlling current, voltage and protecting the battery.
Light pole: The durability of light poles and fixings are also one of the factors that affects the life of solar street lights. If the light poles are made of high-quality materials and the fixings are firmly installed, their lifespan can reach about 25 years.
In addition, the use environment and daily maintenance also have an important impact on the life of solar street lights. In harsh climate conditions, such as extremely cold or hot environments, the life of solar street lights may be shortened. If there is a lack of necessary daily maintenance, such as regular cleaning of solar panels, checking the charge and discharge of batteries, etc., it will also affect the life of solar street lights.
To sum up, the overall service life of solar street lights depends on the life of each component and the collaborative work between them. Therefore, regular maintenance and selecting high-quality components are keys to extending the service life of solar street lights.
