When choosing solar street lights, everyone will be concerned about a question: how long can solar street lights last? This question cannot be simply answered with an exact data, because solar LED street lights are composed of 5 parts, including solar panels, led light sources, solar controllers, solar gel batteries, light poles, and solar street lights. These five major decisions.
The service life of solar panels is more than 25 years, and the service life of light poles can be more than 30years. Components with such a long service life can be completely ignored. Secondly, Solar light controllers can also be ruled out. First, the controller is cheap, easy to source, and easy to maintain and repair. Second, the controller is not easily broken. As long as it is used correctly in accordance with the instructions, it will not cause much threat. Here, the service life of the LED light source and the storage battery is mainly cosidered. The correct use of the storage battery can reach more than 5 years. The so-called correct use of the storage battery means that the manufacturer must consider the capacity of the storage battery when designing the configuration.
If the Solar Panel generates 45Ah per day, then the selected battery capacity must be larger than 45AH to avoid excessive discharge depth affecting the battery`s energy storage capacity and service life. The battery can choose more than 50Ah. Here, regular manufacturers will choose a slightly smaller capacity. Larger batteries, and some small manufacturers will choose smaller or just 45AH batteries in order to reduce the price. It is recommended that customers understand the configuration clearly when purchasing.
