How a PV System Works
The Photovoltaic (PV) System
How it Works:
- Energy from the sun hits the solar modules.
- The modules produce direct current (DC) electricity, which flows through a DC disconnect to the inverter.
- The inverter converts the electricity from DC to alternating current (AC) so that it is compatible with the grid. The inverter also sends data to the Data Acquisition System (DAS).
- The AC electricity then flows through an AC disconnect and a production meter to the AC Panel for energy distribution. At this point, it can either be used for on-site energy needs or sent through a net-utility meter into the grid. The energy sent to the utility grid will then be credited to facility according to pertinent net-metering policies.

Schools across the U.S. have solar installations and classroom activities. See what this month’s featured school is doing with theirs.
Become a Funding Partner
Solar 4R Schools would be nowhere without our funders. See how their projects and learn more about how your organization can fund solar.
This month's featured activity is Create Your Own Solar Oven. Use materials students have around the house to make solar ovens in class and cook snacks.
