- Incentives can drastically reduce your net cost.
The Science Behind Solar Photovoltaics
Solar panels work by capturing sunlight and converting it into electricity. This process relies on a scientific phenomenon known as the photovoltaic effect.
The Photovoltaic Effect
When sunlight hits a solar panel, the photons (particles of light) knock electrons free from atoms within the panel's solar cells. These solar cells are typically made of silicon, a semiconductor material. The flow of these electrons creates a direct current (DC) of electricity.
The Role of the Inverter
Most homes and appliances run on alternating current (AC) electricity, not DC. Therefore, the DC electricity generated by the solar panels must be converted. This is the job of the solar inverter. The inverter takes the DC electricity and transforms it into AC electricity, making it usable for your home.
Connecting to the Grid
Once converted to AC, the electricity flows through your home's electrical panel to power your appliances. If your system produces more electricity than you need, the excess is sent back to the utility grid, often earning you credits through a process called net metering.
