Home Solar + Battery Storage in Massachusetts

Why Go Solar in Massachusetts?

  • Strong Solar Incentives

    On November 26, 2018, the SMART Program became available to solar projects of all types and sizes.1

  • Add a Battery

    With home solar + battery storage, you can power your most needed lights and appliances during a power outage.2

Home Solar Incentives - What is SMART?

Thanks to a state-wide focus on solar-friendly policies, Massachusetts is a growing home solar market.

In 2018, Massachusetts launched their state-wide solar incentive program, the Solar Massachusetts Renewable Target (SMART) Program. Under the SMART program, solar homeowners with the three main utilities (Eversource, National Grid, and Unitil) are eligible for incentive payments from their utility.

SMART incentive payments are rolled out on a “block” system – as more homeowners go solar, there are fewer funds available for SMART incentive payments. The sooner you go solar, the better!3

Interested in adding a battery to your existing solar system? - If you already receive SMART credits, you may qualify for additional SMART incentives beyond what you are already collecting for your home solar system!4



Massachusetts Utility Rates

Massachusetts has the third highest electricity prices in the U.S. with an average price of .23 cents per kWh.5 In only 5 years, from 2012 to 2017, the average utility rate rose 35% in Massachusetts. In just one year, from 2016 to 2017, the average utility rate rose 6% in Massachusetts.6

With home solar + battery storage, you will be able to reduce the electricity you pull from your utility and protect yourself from high utility rates. Excess solar production is stored in your battery, and your battery can power your home at night, on cloudy days, or during a power outage.

Ask Us About Battery Storage

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.2

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.2

With Sunnova SunSafe®, you get solar panels + battery storage installed together. Enjoy increased energy independence, predictable energy costs, and backup power during power outages.2

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

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.

4. If you are already receiving SMART credits from the state of Massachusetts, you may be eligible to receive additional credits when adding a battery. The amount of the incentive will vary annually based on your system’s size and actual production. If you own your PV system, you will need to apply to receive these credits, which will be issued to you directly from the utility. If your PV System is owned by Sunnova and earns SMART credits, we will collect the SMART incentive on your behalf and pass the incentive back to you annually in the form of Visa™ gift card. or other equivalent gift card available at the time, in the amount of the final annual incentive received.  Issuance of gift cards will be fulfilled by a third-party provider 10-12 weeks after the anniversary of the customer’s battery contract. Gift cards are non-transferrable, not for resale, not for use at automated gas pumps and not redeemable for cash. Reward gift cards expire twelve (12) months after issuance. Customer will forfeit any unused funds after the expiration term. Visit https://rewards.groupo.com/Docs/CHA2017.pdf to review the cardholder agreement and all terms and conditions of use. Gift cards may be taxable, depending on the value of the item and the federal, state, and local tax laws applicable to the Customer. SMART credits are issued by the utility for up to 10 years after your PV system was initially installed.
