Storage time of solar street lights

A well-designed solar street light typically lasts 10–20 years 1 as a system. Expect panels 25–30 years 2, LEDs 50,000–100,000 hours (L70), controllers 5–10 years, and LiFePO4 batteries 8–12 years 3 depending on depth of discharge, temperature 4, and sizing margins. . While the lifespan varies by component and environmental factors, modern solar street lights are designed to provide reliable performance for years, often exceeding the longevity of traditional grid-powered lighting. We're talking about things like the solar panel itself, those LED bulbs, the battery storage, and the control unit that manages everything. [PDF]
