What's the lifespan of solar street lights?

Recently, some customers asked me how long the LED solar street light can be used, how long is the service life, etc., and now I will give a unified reply.

The life of a solar street light is determined by its shortest-lived accessories. The accessories of a solar street light are mainly composed of solar panels, controllers, batteries, light sources and light poles. Among them, the service life of the solar panel is more than 20 years. After 20 years, the solar panel will only have a certain light decay (about 30%), but it can continue to be used; then the controller, generally, the service life is 8~ About 10 years, depending on the electronic components inside and the use environment; the second is the battery. In the past, solar street lights generally used lead-acid gel batteries. The service life of this battery is about 3 years, and the lead The acid battery may be very aging, and the capacity is not even up to 10% of the basic capacity, which basically cannot meet the lighting requirements. Most of the batteries used now are lithium batteries. The high and low temperature resistance of lithium batteries is better than that of lead-acid gel batteries, and the number of cycles is more than that of lead-acid gel batteries. More than 5 years; light source The current solar street lights are all LED light sources, and the service life of a good LED light source can reach more than 11 years; if the final light pole is hot-dip galvanized and anti-rust measures are taken, the service life can be 20 years above.

The main factor restricting the life of solar street lamps is the battery, which is the first to be damaged during normal use. At this time, you don't have to worry, you only need to replace the battery and the solar street light can be used normally. At this time, I can recommend the universal maintenance lamp holder of Hishine Group Limited Solar Energy. It has its own battery and a controller with MPPT, which can adapt to solar panels of various voltages. It does not need special accessories, and it also has a light source. All accessories are highly integrated. It is also very convenient to replace, just connect the solar panel cable and put the universal maintenance lamp head on the lamp arm to work normally.

Therefore, the general lifespan of solar street lights is 5-8 years, but most of the accessories can be used normally, just to replace the battery.
