Solar street lights are latest technology lights that are powered by solar energy. These are battery based solar lights also known as stand alone solar lights, which stores electricity generated by solar panel in solar battery.
Solar panels absorb the sunlight and convert the heat into electricity. This generated electricity is then used to power the LEDs/luminaries in the solar street light. These lights are best to use at any outdoor location like street, garden, open roads, etc.
There are various types of solar street lights like standard solar light, semi-integrated solar light and integrated solar street light (all-in-one). In all types of street light, the solar panel charge the solar battery during day time and the stored power is then used to power the LED lamp during night. Street light comes with dusk to dawn sensors, which automatically switch-on the light in evening and off in the morning.
