How Do Solar Panels for Homes Work?
Residential solar systems operate through a straightforward process.
Step 1: Sunlight Absorption
Photovoltaic cells within solar panels absorb sunlight and generate an electrical charge.
Step 2: DC Electricity Generation
The photovoltaic effect produces direct current (DC) electricity.
Step 3: Inverter Conversion
A solar inverter converts DC electricity into alternating current (AC), which is used by household appliances.
Step 4: Power Distribution
Electricity flows through the home's electrical system to power devices and appliances.
Step 5: Grid Interaction
In grid-connected systems, excess electricity can be exported to the utility grid through net metering arrangements. :contentReference[oaicite:2]{index=2}
