1. Quality and types of light sources: Different types of light sources will affect the service life of solar street lamp. Now solar street lamp is commonly used as LED lamp, energy-saving lamp, etc. According to the national label, the average life of energy-saving lamp is more than 6000 hours, and the life of LED lamp is generally more than 5000 hours. That is to say, energy-saving lamp can be used for more than 2 years and LED lamp can be used for more than 10 years. There is also the product quality, quality also determines the service life of the light source.

2. Controller: Controller is one of the core components of solar street lamp. It plays a commanding role in the whole solar street lamp system. It not only controls, monitors and protects the working state of photovoltaic battery components, storage battery and load, but also indirectly protects the load (solar LED street lamp), which provides an effective and relatively stable system. Fixed working environment. Therefore, a controller with stable performance and reliable quality will greatly prolong the service life of solar street lamps.

3. Storage batteries: The commonly used storage batteries for solar street lamps are colloidal batteries and lithium batteries. Although colloidal batteries are cheaper than lithium batteries, the service life of colloidal batteries is much lower than that of lithium batteries. At present, the service life of colloidal batteries used in China is not more than four years, while the minimum service life of lithium batteries is five years, so in many places solar street lamps are used The reason why it is not bright after one year is that the service life of colloidal batteries is short.
