How long is the life of solar street lights? Can it still be used when the life is up?

The life of the solar street light is determined by its shortest life accessories, solar street light accessories are mainly composed of solar panels, controllers, batteries, light sources and lamp poles. Among them, the service life of solar panels is more than 20 years, and after 20 years, solar panels only have a certain light decay (about 30% or more), but they can continue to be used; Then the controller, the general life is about 8 to 10 years, specifically look at the electronic components and the use of the environment; Followed by the battery, the past solar street lights generally use lead-acid colloidal batteries, the service life of this battery is about 3 years, generally fast to the life of lead-acid batteries may be very serious aging, the capacity even the base of 10% can not reach, basically can not meet the lighting needs. And now the use of batteries are mostly the use of lithium batteries, lithium batteries resistance to high and low temperature properties than lead-acid colloidal batteries excellent, the number of cycles than lead-acid colloidal batteries, deep discharge can reach more than 2000 times, so the service life of lithium batteries can have more than 5 years; Light source Now solar street lights are used LED light source, good LED light source life can reach more than 11 years; The last light pole if the use of hot-dip galvanized and do a good job of rust prevention measures, the life can have more than 20 years.

In summary, the main factor restricting the life of solar street lights is the battery, in normal use, the first damaged battery. At this time, you do not need to worry, only need to replace the battery after the solar street lamp can be used normally. At this time, I can recommend our southern solar universal maintenance lamp holder, it comes with a battery, plus a controller with MPPT, can adapt to various voltage solar panels, no special supporting, but also with a light source, all accessories are highly integrated. Replacement is also very convenient, just connect the solar panel line after the universal maintenance lamp head set on the lamp arm can work normally.

Therefore, the general life of solar street lights is 5 to 8 years, but most of the accessories can be used normally, only need to replace the battery. If you do not choose the battery, you can choose our universal maintenance lamp holder in one step, fast and convenient.
