What is a solar panel (PV)?

A solar panel is comprised of many solar cells made from semiconductor materials, typically silicon. These cells are arranged in a grid-like pattern on the surface of the panel. When sunlight hits the solar cells, it generates an electric current through the photovoltaic effect.

How does a solar panel work?

The photovoltaic effect is the process by which a solar cell converts sunlight into electricity. Here's a step-by-step breakdown:

• Sunlight Absorption: When sunlight strikes the surface of a solar cell, photons (light particles) are absorbed by the semiconductor material.
• Electron Excitation: The absorbed energy excites electrons in the semiconductor, causing them to move and create an electric current.
• Electric Field Creation: Solar cells are designed with electric fields that force these excited electrons to move in a specific direction, generating a flow of electric current.
• Current Collection: Metal contacts on the top and bottom of the solar cell capture the electrons and transfer the electric current to an external circuit, producing usable electricity.
