Ask Us About Battery Storage

During a power outage, your home solar system will not work unless you have a battery!


A solar battery stores excess solar production for later use. The energy stored in your battery can help power your home at night, during times of low solar energy production, or even during a power outage.

If the power goes out, a home solar-only system will automatically turn off. With a battery, your home solar + battery storage system can continue to generate solar energy, charge your battery, and power your most needed lights and appliances.3

With Sunnova SunSafe®, you get solar panels + battery storage installed together. Enjoy increased energy independence, predictable energy costs, and backup power during power outages:3

Frequently Asked Questions


If your home solar system is tied to your utility (grid-tied) and you don’t have a battery, your home solar system will not work during a power outage. You will not be able to produce or consume solar energy while the grid is down.

In order to have power during a power outage, you will need a home solar + battery storage system.2

  • During the day, if there is sun: your solar panels will power your home, and any excess energy will charge your battery.
  • At night: your battery can power your essential lights and appliances until it depletes.

Yes! Through our customer portal MySunnova, you can pay your bill online, view your system production, and more.

You can monitor your solar system’s production in the “Monitoring” section of our MySunnova customer portal. The reading of your meter is delayed approximately 24 hours.

To ensure optimal performance of your solar system, Sunnova also monitors every system 24/7 at no additional cost.

Solar panels are extremely durable and built to withstand the elements. As a Sunnova customer, your responsibilities will include:

  • Trim any trees around your solar system that may block the sun from reaching your solar panels.
  • Check that there is no accumulation of leaves, debris, snow, or critters under the solar panels.
  • In more arid climate, you may need to spray your solar panels with a hose to wash off built-up dust and dirt. You can do this while standing on the ground – we strongly advise against you climbing on your roof for any reason.

Each month, you will receive either a bill or a statement from your utility company, in addition to your Sunnova bill. This is because your home solar system will be grid-tied – during times of low or no solar production, you may need to pull electricity from your utility. You may also be eligible for net metering credits for energy your home solar system exports back to your utility.

If the utility company sends monthly statements in lieu of an actual bill with an amount due, you can expect an annual reconciliation of all electricity usage charges and credits.4

2. You may be eligible for a federal Investment Tax Credit (ITC) with the purchase of a solar battery. To receive the full federal tax credit, you must have federal income tax liability at least equal to the value of the tax credit. Additional tax credits may also be available for homeowners in certain states and territories. Sunnova makes no guarantees regarding customer eligibility for tax benefits. Sunnova does not provide tax advice. Contact your personal tax advisor for eligibility.
3. The amount of power available from the battery during a power outage is limited, depending on the loads connected, customer usage and battery configuration (i.e. batteries in certain areas may be set up to provide you with the best economic benefit, which may affect the amount of back-up power available). Solar systems and/or batteries may require repairs after weather events and such repairs may be delayed due to forces outside of our control. No assurances can be given that the solar system or the battery will always work. You should never rely upon either of these to power life support or other medical devices.

5. 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.
6. Limitations apply. Refer to your Limited Warranty or Warranty Agreement for details. For batteries, the system warranty is based on the manufacturers’ warranty.
