How Do Solar Panels Work? | A Complete Guide for Homeowners & Future Professionals

Understanding how solar panels work is the first step toward harnessing the sun's power for your home or career. This guide breaks down the solar energy process in simple terms, explains all the solar PV system components, and explores why this knowledge is critical for anyone considering solar panels for their home or a career in Canada's booming solar industry.

The Photovoltaic Effect: The Science Simplified

At the heart of every solar panel are photovoltaic (PV) cells, typically made from silicon. When photons from sunlight hit these cells, they knock electrons loose from their atoms. This movement of electrons creates a direct current (DC) of electricity. This process, known as the photovoltaic effect, is the fundamental principle behind how solar panels work.

Key Components of a Solar PV System

A full system involves more than just the panels on the roof. Here are the essential solar PV system components:

• Solar Panels (Modules): Groups of PV cells linked together to capture sunlight.

• Inverter: The critical device that converts the DC electricity from the panels into the alternating current (AC) used in your home and on the grid.

• Racking/Mounting System: The secure structure that attaches the panels to your roof or the ground.

• Performance Monitoring System: Allows you to track your system's energy production in real-time.

The solar energy process is a seamless chain of events:

1. Sunlight hits the solar panels and is converted into DC electricity.

2. The DC electricity travels to the inverter.

3. The inverter converts DC electricity into usable AC electricity.

4. The AC electricity flows through your home's electrical panel to power your appliances.

5. Any excess electricity is fed back into the electrical grid (if grid-tied), often earning you credits.
