1, the quality and types of light sources: the type of light source will affect the life of solar street light, solar street lights are now commonly used is LED lights, energy-saving lamps, energy-saving lamps in accordance with national standards, the average life expectancy greater than 6000 hours, LED lamp life More than 50,000 hours, that is, energy-saving lamps can be used for more than two years and LED lamps can be used for more than 10 years. There is the product quality, quality is good or bad also determines the life of the light source.
2. Controller: The controller is one of the core components of solar street lamp, which plays a command role in the entire solar street lamp system. It not only controls, monitors and protects the working status of photovoltaic modules, batteries and loads, and effectively controls the working status of the battery At the same time, also indirectly protect the load (solar led lights), to provide an effective and relatively stable working environment. Therefore, a stable performance, reliable controller will greatly extend the service life of solar street lights.
