Solar street lights are raised light sources which are powered by solar panels generally mounted
on the lighting structure or integrated in the pole itself. The solar panels charge a rechargeable
battery, which powers a fluorescent or LED lamp during the night. Most solar lights turn on and
turn off automatically by sensing outdoor light using solar panel voltage. Solar streetlights are
designed to work throughout the night.
Many can stay lit for more than one night if the sun is not
available for a couple of days. Older models included lamps that were not fluorescent or LED.
Solar lights installed in windy regions are generally equipped with flat panels to better cope with
the winds.
