1. The quality and type of light source: different types of light sources will affect the service life of solar street lamps. Now solar street lamps are commonly used LED lamps, energy-saving lamps, etc. The energy-saving lamps are marked by the country, and the average lifespan is greater than 6000 hours, and the lifespan of LED lamps is average. More than 50,000 hours, that is, energy-saving lamps can be used for more than 2 years and LED lamps can be used for more than 10 years. There is also the quality of the product, the quality of which also determines the service life of the light source.
2. Controller: The controller is one of the core components of the solar street light and plays a commanding role in the entire solar street light system. It not only controls, monitors and protects the working state of the photovoltaic components, batteries and loads, but also effectively controls the working state of the battery. At the same time, it also indirectly protects the load (solar LED street light), providing it with an effective and relatively stable working environment. Therefore, a controller with stable performance and reliable quality will greatly extend the service life of solar street lights.
3. Batteries: The commonly used batteries for solar street lights are gel batteries and lithium batteries. Although the price of gel batteries is lower than that of lithium batteries, the service life of gel batteries is much lower than that of lithium batteries. Now the gel batteries used in China have the most service life. No more than 4 years, and the minimum service life of lithium batteries is 5 years, so in many places, solar street lights do not light up after 3 or 4 years. The main reason is that the service life of colloidal batteries is short.
