The Basics of Solar Energy

Solar energy harnesses the sun’s power to generate electricity, a clean and abundant energy source. This section explains the basic principles of solar energy, mainly focusing on photovoltaic technology, and traces the evolution from traditional solar panels to modern solar roofs.

How Solar Energy Works

The core technology behind solar energy is photovoltaic (PV) cells. PV cells are designed to capture sunlight and convert it into electricity. This process begins when photons, or light particles, strike the surface of a solar cell, typically made of semiconductor materials such as silicon. The energy from the photons excites the electrons in the semiconductor material, causing them to break free from their atomic bonds. These free electrons move through the material to produce direct current (DC) electricity.

DC electricity can’t be used directly in most homes because they operate on alternating current (AC). Therefore, an inverter converts the DC electricity into usable AC electricity. Once converted, this electricity can power household appliances, charge electric vehicles, or be stored in batteries for later use.
