At The Solar Group, we believe solar energy should be accessible, understandable, and practical for every business or property owner. Whether you’re exploring rooftop solar, considering a solar farm, or evaluating solar parking structures, it all starts with one question: how do solar panels actually work? Here’s a clear and simple explanation of the process, broken down into everyday language.
It Starts with Sunlight
Solar panels are made up of many small units called photovoltaic (PV) cells. These cells are typically made from silicon, a material that reacts when sunlight hits it. When light from the sun reaches these solar cells, it excites the electrons inside, setting them into motion.
This flow of electrons is what generates electricity. Think of it like flipping on a light switch. The sun is your energy source, and the solar panel is the switch that turns that energy into usable power.
Direct Current Becomes Usable Electricity
The electricity that flows out of a solar panel is called direct current, or DC electricity. However, most buildings in the United States run on alternating current, or AC electricity. To make the energy usable, the system includes a device called an inverter.
The inverter takes the DC electricity generated by the solar panels and converts it into AC electricity. This is the form of power that runs lights, appliances, HVAC systems, and everything else in a modern building.
Powering Your Building and the Grid
Once converted to AC power, the electricity flows directly into your building’s electrical system. It powers your lighting, equipment, and other energy needs. If your solar system produces more electricity than your building uses at any given time, the extra energy is sent back to the utility grid.
Many areas, including Arizona, offer net metering programs. This means you get credit for the extra electricity your system sends to the grid, which can reduce your future utility bills.
Ongoing Monitoring and Long-Term Savings
Most commercial solar systems today come with real-time monitoring tools. You can log into an app or portal to see how much energy your system is producing each day, month, or year. This transparency allows you to track performance, spot potential issues early, and see your energy savings over time.
Over the lifespan of the system, your business can significantly reduce its electricity expenses while protecting against rising utility rates.
Why Understanding This Matters
You do not need to be an engineer to understand the benefits of solar. Once you know the basics of how solar panels work, it becomes clear why businesses across the country are investing in solar energy.
