What is the lifespan of solar street lights?

The lifespan of solar street lights mainly depends on that of solar batteries. The battery lifespan not only depends on its quality, but also depth of discharge (DoD), which indicates the percentage of battery discharge divided by battery rated capacity. The lower the DoD is, the longer the lifespan is. INLUX SOLAR uses a low battery discharge-depth solution, combined with brand new high quality LiFePO4  (lithium iron phosphate) batteries. Our LiFePO4 (lithium iron phosphate) battery lifespan can reach more than 10 years, ternary lithium and colloidal battery life can reach more than 5 years.
