The Sun produces energy through nuclear fusion. Every minute, enough energy (photons) reaches Earth’s surface to meet the world’s energy demand for a year.
Solar Modules absorb Light (photons) from the sun and convert it into electrical energy (electrons). This process generates direct current (DC) electricity, which is then routed to an inverter.
The Inverter converts DC electricity generated by the solar modules into alternating current (AC). Alternating current is the form of electricity used in homes and facilities.
The Solar Meter measures electrical energy produced by the solar array. This is the same grade of meter the utility uses. For API Power Purchase Agreement projects, the solar meter is used to bill the client for energy monthly. The solar meter is also used to track the amount of renewable energy credits have been generated.
The Utility Meter measures the facility electrical demand (load). However, the solar electricity gets used first when a facility owner installs a solar power system. The Utility Grid seamlessly supplements power (as needed) whenever solar power is not enough.
Whenever the solar power is not used by the facility, it automatically feeds into the utility grid. There it is essentially “stored” until the facility needs it. With net metering, this means the utility meter spins backward to show how much solar electricity got stored into the grid. This generates a “credit” on the facility owners utility bill. The utility meter begins to spin forward again when the facility needs more electricity than solar can provide.
