Nowadays, solar streetlights usually use LED light sources. After years of technical development, the life span of LED lights has stabilized. Of course, despite the use of LED light sources, the quality and service life of light sources of different prices are not the same. A better quality LED street light can be used for more than 10 years, and a general LDE light source may be able to use for 3-5 years.

The solar panel is the power generation equipment of the solar street light system. It consists of silicon wafers, commonly known as photovoltaic modules, and has a long service life.
However, if you want to make the solar panel reach the expected life span, you should pay attention to maintenance during use. The main function of solar panels is to convert solar light energy into electrical energy to be stored in rechargeable batteries. Solar panels should not be shaded during use and trees should be trimmed regularly if the top of the solar panel is shaded.

The situation with rechargeable batteries is more complicated. In addition to the operating temperature and waterproof performance, the type of battery is also a key factor affecting the life of LED solar street lights. Generally speaking, the life of lead-acid batteries is 2-4 years, and the life of lithium iron phosphate batteries is 5-8 years. The life of the battery is determined by its cycle discharge life.
The selection of battery capacity generally follows the following principles. First, to meet the premise of night lighting, as far as possible during the day to store the energy of solar modules. At the same time, it must be able to store the electrical energy required for continuous cloudy days and nighttime lighting. The capacity of the battery is too small to meet the needs of night lighting. If the battery capacity is too large, the battery is always in a state of power loss, which affects the service life of the battery and causes waste. The capacity of the battery is 6 times the daily discharge capacity, which can ensure a longer period of continuous cloudy days.

The controller of solar street lights plays a very important role in solar street lights, it can effectively control the working state of the battery, and also can indirectly protect the solar street light. A good controller must be an accurate and stable performance so that the controller can control, detect and protect the battery components as well as the battery. The stability of the controller function is also different for different prices, and the service life will also be different. Want to use solar street lights for a longer time, you can also buy a better quality controller.
The working environment of the lamps and lanterns
The working environment of the lamps and lanterns has a crucial impact on the service life, especially outdoor solar street lights. Some of the main environmental impact factors are temperature, humidity, dust, etc. Why does the temperature affect the service life of solar street lights? Because the battery of solar street light is sensitive to the ambient temperature, such as a ternary lithium battery, the ambient temperature can not exceed -20C to 40C, because its working ambient temperature can only reach -10C to 60C.
