The service life of
Solar Street Lights is affected by many factors, including product quality, usage environment, and component life. The following is a detailed analysis of the service life of the main components of
Solar Street Lights:
LED light source:
Lifespan: The service life of LED light sources can usually reach 50,000 hours.
Assuming that it is used for 10 hours a day, its service life is at least 10 years (50,000 hours ÷ 10 hours/day ÷ 365 days/year ≈ 13.7 years).
Battery:
Previous batteries: The service life of traditional lead-acid gel batteries is generally around 3 years.
Now batteries: Most
Solar Street Lights use lithium batteries, which have better high and low temperature resistance, more cycles than lead-acid gel batteries, and can be discharged more than 2,000 times in depth, so the service life of lithium batteries can be more than 5 years.
Solar panels:
Solar Street Lights generally use polycrystalline panels with a service life of around 15 years.
After 20 years, the solar panels may have a certain light decay (about 30% or more), but they can still be used.
Controller:
Lifespan: The general lifespan of the controller is about 8 to 10 years, depending on the electronic components inside and the use environment.
Light pole:
If it is Q235 steel, its service life can reach about 25 years.
If hot-dip galvanized steel is used and anti-rust measures are taken, the service life can be more than 20 years.
In summary, the service life of
Solar Street Lights is a relative concept, and the specific service life depends on the actual situation of each component and the overall maintenance. Generally speaking, under normal use and maintenance, the service life of
Solar Street Lights can reach 5 to 15 years, or even longer. In order to ensure the normal operation of
Solar Street Lights and extend its service life, regular maintenance and inspection are required, such as timely replacement of damaged panels, upgrading aging controllers, and checking wire connections.
