How Does Solar Energy Work?

At its core, solar energy is the process of converting sunlight into electricity using photovoltaic (PV) cells. These cells are made of semiconductor materials, typically silicon, which can absorb sunlight and generate an electric current. When sunlight hits the PV cells, the energy from the photons in the sunlight excites the electrons in the semiconductor material, causing them to move and create an electric voltage. This voltage can then be harnessed and converted into usable electricity through an inverter, which transforms the direct current (DC) produced by the PV cells into alternating current (AC) that can be used to power our homes, businesses, and communities.

There are various types of PV systems, including rooftop solar panels, ground-mounted arrays, and solar farms. Rooftop solar panels are typically installed on residential or commercial rooftops and are connected to the local power grid, allowing excess electricity to be fed back into the grid and credited to the owner through a process called net metering. Ground-mounted arrays and solar farms are larger-scale installations that can generate electricity to power entire communities or contribute to the grid.
