Your solar system will provide most of the power your home needs. But at night and on cloudy days, it won’t. Your system will be connected to your utility company’s electric grid to supply energy during the times your system isn’t producing enough on its own. This is known as interconnection, and it allows for the bidirectional transmission of energy between your home and the electric grid.
Net metering is the concept of measuring both the energy you receive from the grid, as well as any excess energy your system produces and sends back to it. Your utility company will supply your net meter to keep track of what you consume from and export to the grid. You may receive credit for exported energy to help offset the cost of what you consume.
Please note: You will have two energy meters and therefore two monthly statements. Sunnova will provide you with a solar meter to measure your solar production, in addition to your utility net meter. Net metering may appear on your bill in its acronym form, NEM (Net Energy Metering).*
* Your electricity needs will vary based on your usage, the energy efficiency of your home and other factors. Your solar system’s production will vary based on weather and other factors. Sunnova makes no guarantees regarding credit for net energy exported to the electric grid, and any credit provided (now or in the future) is subject to change or termination by executive, legislative or regulatory action.
