Solar takes advantage of a free and powerful energy source – the sun.
In a single hour, the sun transmits more energy to the earth’s surface than the world uses in a year.
Solar converts this energy into electricity, making it a simple, clean and cost-effective way to power our lives. It’s dependable, too – because unlike fossil fuels, the sun’s energy is unlimited.Just imagine what that could do for your wallet and the environment.
What are Solar Panels?
Placed on roofs or on the ground, solar panels capture the sunlight and convert it into electricity. Solar works based on light rather than heat. It’s true that the light the panels receive; the more electricity they can generate. But they still work on cloudy days – just as a solar-powered calculator does. Their full name is solar photovoltaic panels, or PV. (“Photo” means “light” and “volts” means electricity.)
How Does SolarWork?
- The panels are frames made up of solar (PV) cells (these are layers of silicon).
- The sun’s radiation hits these cells and is converted to direct current (DC) energy.
- This DC energy speeds to an electrical device called an inverter, which converts DC energy into alternating current (AC) energy.
- The AC electricity can then go directly to power equipment and lighting.
