Your solar system will provide most of the power your home needs. During cloudy or foggy days, there will be low production and at night, the system won’t produce energy. If you have a battery connected to your solar system, you may receive power from it when your system is not producing; thereby reducing the amount of power you need from the grid.
However, whether you have a battery or not, your system will be connected to your utility company’s electric grid to supply electricity during the times your system isn’t producing enough on its own or the battery is depleted. 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 it1. 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.
Net metering is not available in all markets. We recommend you check your local utility.
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 utility bill in its acronym form, NEM (Net Energy Metering).1
1: 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.
