Solar panels, also known as photovoltaics (PV), capture the sun's energy and convert it into electricity for use in your home. Installing solar panels allows you to generate your own renewable energy. Because sunlight is free, your electricity costs will be reduced after the initial installation.

A solar PV panel is made up of many cells made of semi-conducting material, most commonly silicon. When light shines on this material, an electric current flows.

The cells do not require direct sunlight to function and can even function on cloudy days. However, the more sunlight there is, the more electricity is generated.
