The service life of solar street lights is determined by accessories with a short service life. Solar street light accessories are mainly composed of solar panels, controllers, batteries, light sources, light poles, etc. Solar panels have a lifespan of more than 20 years. After 20 years, solar panels have only a certain amount of light attenuation (about 30% or more), but they can continue to be used; followed by the controller, which generally has a service life of 8 to 10 years depending on the electronic components and usage environment; then is the battery. In the past, solar street lights generally used lead-acid gel batteries. This battery has a lifespan of about 3 years. Generally speaking, lead-acid batteries that are close to their service life may be seriously aged, and their capacity may not even reach 10% of the basic capacity, making it difficult to meet lighting requirements. Most batteries in use today are lithium batteries. The high and low temperature resistance of lithium batteries is better than that of lead-acid gel batteries. The number of cycles is also higher than that of lead-acid gel batteries. The deep flow can reach more than 2000 times. Therefore, the service life of lithium batteries can exceed 5 years; at present, solar street lights use LED light sources, and the service life of LED light sources can reach more than 11 years; if a light pole is hot-dip galvanized, and anti-rust measures are taken, the service life can exceed 20 years.
In summary, the main factor restricting the service life of solar street lights is the battery. During normal use, the first thing that is damaged is the battery. At this time, you don’t have to worry. Just replace the battery and the solar street light can be used normally. At this point, I can recommend our South German Solar Universal Maintenance Lamp Head. It has its own battery and MPPT controller, it can adapt to solar panels of various voltages without special support, it also comes with a light source, and all accessories are highly integrated. It is also easy to replace. Just connect the solar panel wiring, place the universal maintenance light head on the light arm and it will work.
Therefore, the general service life of solar street lights is 5~8 years, but most accessories can be used normally. Just change the battery. If you can’t choose a battery, you can choose our universal repair lamp head in South Germany, which is quick and convenient.
