How Do Solar Panels Actually Work?

How Do Solar Panels Work

We all know that solar panels transform direct sunlight into electricity that can power our homes. Not many people know the science behind them though. At Clean Choice we strive to offer quality, honest service, so we want you to understand every part of the process. Here, we’ll explore how solar energy works - it’s simpler than you think!

Two Types of Solar Panels

Before we dive into details, it’s important you understand the two types of solar panels. Thermal panels capture solar energy and use it to heat water. That hot water is used directly in household applications or can be converted into electricity with additional parts. On the other hand, photovoltaic (PV) panels use magnetic forces to convert sunlight directly into electricity. Due to superior versatility in residential settings, we install PVs exclusively.

Photovoltaic Panels

PV solar panels are made up of individual silicon cells. The two sides of each cell are mixed with different materials to create a positive-negative bond or junction. Photons of sunlight shoot down onto the cells and dislodge electrons out of this junction. Metal plates on the edge of the cells then guide loose electrons into wires. At this point the electrons flow like any other source of electricity.

These dislodged electrons form a circuit that works through your home system and ultimately back into the PV cells. As such, nothing is being consumed. As long as the sun is shining, clean electricity flows through your home. This renewable aspect of solar energy makes it an environmentally friendly choice but it’s also a smart long-term investment.
