How does a solar panel work?

A solar panel, also known as a photovoltaic (PV) panel, works by converting sunlight into electricity. The panel consists of multiple solar cells made of semiconductor materials, such as silicon. These cells contain two layers of silicon: one positively charged and the other negatively charged. When sunlight hits the solar panel, it excites the electrons in the semiconductor material, causing them to move freely. The movement of these electrons creates an electric current, which can be harnessed and used as a source of energy. This direct current (DC) is then converted into alternating current (AC) through an inverter, making it suitable for use in our homes and businesses. Solar panels are becoming increasingly popular due to their ability to sustainably generate clean and renewable energy.
