Solar generators typically last 10-30 years, with LiFePO4 batteries providing 3,000-5,000 charge cycles (15-25 years) while solar panels last 25-30 years. Battery type, maintenance quality, usage patterns, and environmental conditions all impact longevity.

Solar street lights can generate electricity mainly by using the photovoltaic effect of semiconductor materials, which can convert solar light radiation into electricity. A solar cell is composed of two different types of semiconductors, N-type and P-type.
