How Electric Solar Panels for Homes Generate Power
The magic behind solar panels is the photovoltaic (PV) effect. When sunlight strikes a panel, it excites electrons in the specialized material, creating a direct current (DC). Since homes use alternating current (AC), an essential component called an inverter converts this DC power into usable AC electricity. Any excess power can be sent to the utility grid or stored in a battery. This process turns your home into a mini power plant.
For a deeper dive, see our guide on How Solar Panels Work: A Comprehensive Guide or the Solar Photovoltaic Technology Basics from the U.S. Department of Energy.
Understanding the Core Components
A complete solar PV system includes several key components:
- Solar Panels (Modules): Composed of photovoltaic cells, these capture sunlight and convert it into DC electricity.
- Inverters: This crucial device converts DC power from the panels into AC power for your home. Different types (string inverters, microinverters) offer various benefits. Learn more in The Ultimate Guide to Solar Inverters.
- Racking (Mounting): This is the structure that securely holds the panels on your roof or the ground, designed to withstand weather and optimize sun exposure.
- Wiring: The wiring connects all components, ensuring safe and efficient energy transfer from the panels to your home.
Solar PV vs. Solar Thermal
It’s important to distinguish between two types of solar technology:
- Solar PV (photovoltaic) panels generate electricity. This is what most people mean when they talk about electric solar panels for homes.
- Solar thermal panels use sunlight to heat water for your home.
While both use the sun, they serve different purposes. This guide focuses on solar PV panels that produce electricity.
Types of Home Solar Systems and Key Features
Choosing the right electric solar panels for homes depends on your goals, energy use, and desire for independence. Our Residential Solar Solutions Guide can help you decide.
Grid-Tied Systems and Net Metering
The most common setup in East Tennessee is a grid-tied system, which connects your solar panels to the local utility grid.
- Your panels first power your home.
- Excess power is sent to the grid.
- You draw power from the grid when your panels aren’t producing, like at night.
With net metering, you receive credit for the excess electricity you send to the grid, often at a 1:1 rate. This can dramatically lower or even eliminate your electricity bill. Policies vary, so check your local utility’s program. Learn more here: Do East Tennessee Utility Companies Buy Back Solar Power? Find Out Here!.
Note: Standard grid-tied systems shut down during a power outage for safety. For backup power, you need a solar-plus-storage system.
Solar Plus Storage: Your Path to Energy Independence
A solar-plus-storage system combines solar panels with a battery for true energy independence.
- Power During Outages: Your battery provides seamless backup power when the grid fails.
- Optimized Energy Use: Store solar energy from the day to use at night, reducing reliance on the grid.
- Increased Self-Sufficiency: Gain more control over your power supply and protection from rising utility rates.
