Renewable Energy Products Solar Panels Heat

How do solar panels generate electricity?

There are two primary ways in which solar panels generate electricity: thermal conversion and photovoltaic effect. Photovoltaic solar panels are much more common than those that utilize thermal conversion, so we'll be focusing on PV solar panels. Sunlight strikes the solar cells of the solar panel.

How do solar photovoltaics work?

Solar photovoltaics work by directly converting sunlight into electricity through the photovoltaic effect. This process occurs in photovoltaic cells, usually made of silicon, a semiconductor material. When sunlight hits these cells, the photons transfer their energy to the electrons in the material, generating a direct electric current.

How do solar panels convert light into electricity?

Solar panels convert the energy of photons (light particles) into electricity (as we discuss in The Beginner's Guide to Solar Energy). This process is called the photovoltaic effect. When a photon hits a photovoltaic (PV) device, its energy is transferred from the photon to the local electrons in the material.
