Solar panels, also called photovoltaic or PV panels, consist of solar cells designed to capture the radiant light and heat contained in sunlight and convert it into clean energy that can be used in the home. When sunlight hits the solar panel, the photons of energy are converted into direct current (DC) electricity, which is then converted into alternating current (AC) electricity for use in the home. Solar panels are often grouped together to form a solar grid or solar array, allowing you to capture and harness the right amount of energy for your needs.
