Solar incentives help mitigate the cost of installing solar panels on your home. These financial incentives are designed to encourage more people to switch to renewable energy. Various kinds of incentives, including discounts, cash back or monthly utility bill credits, might be available to you. Some incentives may be offered by the Massachusetts government, by your utility company or by county or municipality, while others are federal. Some broad categories of solar incentives include:

  • Solar Renewable Energy Certificate (SREC): Generally, solar systems that produce more than a predetermined (generally small) amount of electricity can qualify for SRECs or other similar performance-based incentives. SRECs and performance-based incentives in general are typically offered at the state level. SRECs can be sold to your utility company or another buyer, and this is usually considered part of your taxable income.
  • Net Metering: Net metering is an incentive you can get after your solar system is up and running. If you've signed a net metering agreement with your Westport utility company, the company will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some locations, this is a dollar-for-dollar credit, while in others you may make back a percentage of the value.
  • Tax Exemptions: These can come in the form of property tax exemptions, which would allow you to ignore the value of your solar system when paying taxes on your house. You may also qualify for an exemption on sales tax at the time of purchase.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the government.
  • Rebates: Rebates, or cash back after a purchase, are usually applied before any solar tax credits are calculated. These rebates can be offered by your local utility company, by your state or by your county.

Federal Solar Incentives

Federal solar incentives are probably the first thing that you think of when thinking about solar incentives. The Federal Solar Investment Tax Credit, or ITC, is probably the best-known federal solar incentive. The ITC allows you to claim a tax credit for a set percentage of your solar system's cost.

The ITC can be applied to solar systems installed after January 1, 2006, on a primary or secondary residence that you own in the United States. Initially, the credit applied to 30% of the total cost – for panels, equipment, labor and accessories – although the percentage may range from 26-30%, depending on when your solar system was installed. There is no cap on the amount you can claim.

To know exactly how much money the ITC could save you, contact your local Westport solar panel installation expert.

In August 2022, the Inflation Reduction Act made revisions to the ITC, now referred to as the Clean Energy Credit. For solar systems installed between January 1, 2022, and December 31, 2032, homeowners can receive a credit equal to 30% of the total cost. This percentage will decrease annually after 2032 until the Clean Energy Credit expires in 2035. Starting in 2023, it will also be easier to get credits for energy storage systems with the new act.

More information about the new Inflation Reduction Act can be found here. Your local Westport solar panel installation expert is the best person to answer your questions about the new Clean Energy Credit and how it will apply to you.

State & Local Solar Incentives

Not all solar incentives are federal; rebates, tax credits and more might also be offered at the state and local level. These solar incentives — which may be provided by the state of Massachusetts, or by your county or municipality — could be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Westport

The nationwide use of solar energy has increased enormously in the last 15 years, in part thanks to the growth in the number of solar incentives. You may get these incentives from the federal government, the Massachusetts government or your local utility company. We suggest talking to your local Westport solar installer to learn more about these incentives and to be sure that you're getting all the money you can for your solar system.

EcoWatch's Westport, MA Solar Incentives FAQs

If I already have solar panels, can I still claim incentives?

An excellent idea would be to talk to the company that installed your solar system – or reach out to a local Westport solar installer — to learn about which incentives you may qualify for. If your solar panels were installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Solar panels installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are some of the environmental benefits of switching to solar energy?

Solar energy is a renewable energy source — by switching where you get your energy, you help reduce the strain on our planet's resources. A solar system can also lower your home's CO2 emissions by 200 pounds a year, or around 4,000 pounds in 20 years.

Can I use both solar and another type of renewable energy to power my home?

You can use multiple types of renewable energy, or a combination of renewable and non-renewable energy, to power your home. Make sure you discuss your plan with your local Westport solar installer. They can help you as you plan for your project and also help you understand the various incentives that you will or won't qualify for.

What if I am planning to add solar panels to a rental property, vacation home or commercial property? Can I still qualify for incentives?

While we recommend speaking with your local solar installer and/or tax professional to fully understand what solar incentives apply to you, many incentives apply to a second home, as long as it is in the United States and owned by you. There may be additional incentives available specifically for commercial properties, depending on the details.
