At night or during times of low solar production (like cloudy or foggy days), your home will pull electricity from your utility to meet your home energy needs. This is why you may continue to receive a bill from your utility even if your home has a solar system.
However, with a home solar system and smart energy consumption, you may be able to reduce your utility bill. In addition, on sunny days, your home solar system may produce more energy that your home can use. If your utility provides net metering credits for sending excess energy back to the grid, this can help you offset the cost of the utility electricity.
Individual savings will vary based on your utility rate, your energy consumption habits, the solar system equipment installed on your property, your tax incentives eligibility, weather and other factors. In some states Sunnova’s products are not designed to offer savings. Customers located in states or territories other than CA, CT, MA, RI, NY and NJ are likely to perceive savings substantially lower than 20%, if any. Individual savings estimates are based on your solar energy production, your solar kWh rate, potential tax incentives, your utility kWh rate at the time of purchase, and projected increases in the utility rate (based on historical data and national averages). Estimates do not take into consideration other changes in utility rates. Such changes could affect your overall estimated savings. Sunnova does not guarantee savings.
