For the lighting industry, the life of solar street lights is relatively long. However, as the use time increases, and some human factors may affect the life of solar street lights. So what are the factors that affect the life of solar street lights? The technology of solar street light manufacturers will tell you.
The life of solar street lights is much higher than that of ordinary power lights. The service life of solar modules is 25 years; the average life of low-pressure sodium lamps is 18,000 hours, and the average life of low-pressure and high-efficiency three-primary energy-saving lamps is 6000 hours. The average life span is more than 50,000 hours. The life span of the solar battery is 2-5 years lower than that of 38AH and 3-7 years lower than 38-50AH. According to the regulations of the local community, according to the local price bureau “according to the one-time residential street lamp maintenance fee of 6 yuan per square meter of pure residential building area”, the initial investment of ordinary lights is much higher than the initial investment in solar lights.

一: Consider the service life of the LED light source and the battery, and use the battery correctly, the service life can reach more than 5 years. The so-called correct use of batteries means that solar street lamp manufacturers should consider the carrying capacity of the batteries when designing and configuring them.
2: Light source starter, different starting methods are different, and different ballasts or driving power lamps are required. This part has a great influence on the light source, especially the LED light source. It is very important to check whether the constant current source is good and whether the parameter range is suitable for the light source. Mainly include: constant current accuracy, output efficiency, protection circuit, parameter setting range, etc.
3: The solar panel produces 45Ah every day, so the battery capacity must be greater than 45AH. Avoid excessive discharge depth, which will affect the storage capacity and service life of the battery.
4: The controller solar street light system not only controls, monitors and protects the working status of photovoltaic modules, batteries and loads. While effectively controlling the working state of the battery, it also indirectly protects the load. It provides an effective and relatively stable working environment, especially under critical conditions such as low battery power or under-voltage operation.
