Solar panels work by converting incoming photons of sunlight into usable electricity through the photovoltaic effect. Sound complicated? We break it all down with easy-to-understand language.
When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
When light with enough energy comes in, it knocks an electron off with enough energy to cross the depletion zone (the wrong way), which gives it enough potential energy to do work. We send the electron on it way down a wire where it can be used as electricity. Imagine it like a slide. The light lets the electrons climb a ladder and lets it slide down (move through the wire) until they eventually make it all the way through the circuit and back to the ladder. Fun fact: solar panels are the only power generation method we use that produces DC current rather than AC.
When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit.
Solar power works by converting sunlight into electricity through the photovoltaic (PV) effect. The PV effect is when photons from the sun’s rays knock electrons from their atomic orbit and channel them into an electrical current.
Solar PV is based on the photovoltaic effect, by which a photon (the basic unit of light) impacts a semi-conductor surface like silicon and generates the release of an electron. Solar thermal is less sophisticated and simply the direct heating of water (or other fluids) by sunlight.
A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity.
So how do solar panels work on a house? The PV modules and arrays are mounted in a way that best orients them toward the sun. This allows them to garner the sunshine most efficiently, even on cloudy days.

PV solar panels have consistently made up the vast majority of modern solar panels. However, there are some other unique ways to harness the sun’s power: ... The Crescent Dunes solar thermal power project near Tonopah, Nevada benefits from the sunshine and open land of the Mojave Desert · Concentrating Solar Power (CSP) works by harnessing the sun’s energy as a heating source.
