A solar panel, often called a photovoltaic module, is a device that converts sunlight directly into electricity. This transformation relies on the photovoltaic effect, a physical phenomenon discovered in the nineteenth century. Each panel contains dozens of solar cells, typically made from crystalline silicon. These cells absorb photons from sunlight, freeing electrons from their atomic bonds. When electrons move through the material, they generate a flow of direct current electricity. Multiple panels connected together form an array, capable of producing substantial amounts of power.

Solar panels capture energy from sunlight and turn it into electricity. They do this without moving parts, without fuel, and without creating pollution. This simple concept has made them one of the most important technologies for clean energy production today.

Solar panels have become a mature, cost-effective technology for generating clean electricity. They utilities a reliable source of energy.

A solar panel is made up of many smaller units called solar cells. These cells are typically made from silicon, a common element found in sand. When sunlight hits the silicon cell, it knocks electrons loose from their atoms.

Solar panels have gone from powering satellites to powering homes and businesses worldwide. They offer a clean, quiet, and increasingly affordable way to generate electricity. The sun provides more than enough energy in one hour to power the entire world for a full year.
