The life of solar street lights cannot only be calculated as the life of the lamp beads, but the lamp beads, controller, and battery should be considered, mainly the life of the battery. At present, the life of lamp beads on the market is generally about 50,000 hours,
the life of solar panels is more than 20 years,
and the life of controllers is generally more than 10 years, depending on the life of electronic components.
The battery life is short for solar street lights. Generally, lead-acid batteries are 2-4 years, and lithium batteries are 4-8 years, depending on the manufacturer's materials.
Nowadays, the solar street light industry is dominated by lead-acid batteries, and the batteries are changed every few years.
