Learn the basics of how photovoltaic (PV) technology works with these resources from the DOE Solar Energy Technologies Office.
When the sun shines onto a solar panel, photons from the sunlight are absorbed by the cells in the panel, which creates an electric field across the layers and causes electricity to flow.
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
In a nutshell, solar panels generate electricity when photons (those particles of sunlight we discussed before) hit solar cells. The process is called the photovoltaic effect.
Solar Energy The sun emits solar radiation in the form of light. Solar energy technologies capture this radiation and turn it into useful forms of energy. There are two main types of solar
How do solar panels work? Learn the photovoltaic effect, solar panel technology, and efficiency in 2025—clear steps, real-world examples, and pro tips from SolarTech.
How does solar power work? This article lays out the basic science of how solar panels work and how it relates to powering your home and saving money.
Some plug-in solar systems come with batteries to store power for use during peak demand when electricity rates spike and when storms or heat waves knock out the grid.
