Learn the basics of how photovoltaic (PV) technology works with these resources from the DOE Solar Energy Technologies Office.
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.
Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials.
Since 2004, most PV systems in the United States are grid-connected—they are connected to an electric power grid. These PV systems are installed on or near homes and buildings and at utility-scale power plants that have at least 1 megawatt of electric-generation capacity.
Learn more about photovoltaic systems that convert light energy into electricity. Enough energy from the sun hits the earth every hour to power the planet for an entire year—and solar photovoltaic (PV) systems are a clean, cost-effective way to harness that power for homes and businesses.

Solar cells, also called photovoltaic cells, convert sunlight directly into electricity. Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.
Solar panels work by converting incoming photons of sunlight into usable electricity through the photovoltaic effect.
Main components of a solar power system. Photovoltaic cells: They are able to capture direct sunlight as “photons”. They also comprise sandwiched layers of semi-conductor particles, like phosphorous and boron.
Solar panels reduce your energy bills, minimize your reliance on fossil fuels, and increase your independence from your utility. They even increase the value of your home by about 4% on average, based on multiple studies.
