How Residential Solar Works
Learn the basics behind residential solar energy systems.
A residential solar energy system is a great way to power your home with clean, renewable, cost stable electricity. The following diagram illustrates how commercial solar works. Pasted Graphic

1. Solar Array: Powering your home with the sun starts here. The solar array is comprised of a series of solar panels. The bigger the array, the more electricity it is capable of producing. When sunlight hits the solar array, DC electricity is generated.
2. Inverter: The DC electricity from your array travels to the inverter, where it is converted from DC to AC electricity. AC electricity is identical to the type of power you receive from the utility power grid.
3. Electric Service Panel: AC electricity from your inverter is passed to the electric service panel where it is routed to power your home’s various electric loads.
4. Utility Power Grid: When your solar electric system generates more power than your home is consuming, excess electricity is routed to the utility’s power grid. When you feed electricity back to the grid, your meter will spin backwards, earning you credits on your bill.
