A solar lantern is a portable lighting device that uses energy from the sun to produce light—no grid electricity or fuel required.
How it works
A solar lantern has three main parts:
- Solar panel – captures sunlight and converts it into electricity (based on photovoltaic effect)
- Battery – stores the electricity for use at night
- LED light – provides efficient illumination using very little power
During the day, the panel charges the battery. At night, the stored energy powers the light.
