Solar Basics

This diagram shows how sunlight is converted to clean electricity:

1. Solar Modules

The solar panels or modules are made up of photovoltaic (PV) cells, which convert sunlight into DC power.

2. Inverter

The DC electricity from your array travels to the inverter, where it is converted from DC to AC electricity. AC electricity is the type of power you receive from the utility power grid and use to power your home or business.

3. Electric Service Panel

AC electricity from your inverter passes to the electric service panel, often called a “breaker box,” where it is routed to power your facility’s various electric loads.

4. Utility Power Grid

When your solar PV system generates more power than your business is consuming, excess electricity is routed to the power grid. When you feed electricity back to the grid your meter will spin backwards, earning you credits on your bill! This is known as “net metering.”
