Streetlights powered by solar panels are useful for illuminating areas without expensive or disruptive installation of overhead power lines. They are often used in remote locations and developing countries, and also in suburban areas where the additional cost of use of electric power is considered uneconomical.
They can be used to provide local lighting of paths and crosswalks in residential areas during the night, to complement security lighting and to reduce energy usage. They can also be used in more complex systems where the light source itself switches on and off in a programmed manner, perhaps as part of a timed control system or an astronomical time switch.
What is solar street light?
A solar street light is an outdoor light fixture which harnesses the energy of the sun and uses it to light up streets, pathways, and parking lots. It consists of a panel that absorbs sunlight during the day and stores it in batteries. At night, the stored energy is used to power the light.
The first solar street lights were developed in the 1960s, but they were too expensive for widespread use. Over time, however, more efficient technologies have been developed and prices have come down considerably. Nowadays, solar street lights are widely used around the world.
Sometimes people want to help the earth, but it's hard. Maybe you can't give up your car. Maybe you can't buy a bunch of new appliances for your house.
But what if you could do something that saved the planet… and saved money?
Solar street lighting is the answer.
You've seen solar panels, right? They're those rectangular things on the roof of houses and businesses. They gather energy from the sun, which they turn into electricity that powers homes and businesses.
Well, solar street lights work in exactly the same way—except instead of putting them on roofs, we put them on poles. And instead of being used to power homes and businesses, they power outdoor street lights—which means they don't have to be connected to electric grids! It’s a win-win. The earth wins because solar energy is clean energy; you win because solar street lights are more affordable than grid-powered street lights.
