The phrase "solar incentives" refers broadly to financial incentives implemented by the government and by solar companies to encourage people to use renewable energy by making the installation and use of solar panels more affordable. Incentives may include things like discounts, cash back or monthly utility bill credits. Some incentives are offered federally, while others are handled by the Massachusetts government or by your utility company, county or municipality. Types of solar incentives might include:

  • Solar Renewable Energy Certificate (SREC): SRECs and other similar performance-based incentives are typically handled by your state government. Once your solar panel system meets the threshold (generally a small amount of energy production), you can receive SRECs that you can then sell to your utility company or other buyers. The money you make is generally considered part of your taxable income.
  • Net Metering: Net metering becomes relevant once your solar panels are up and running. If you have a net metering agreement with your Westport utility company, the company will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in other places you may get refunded a percentage of the value.
  • Tax Exemptions: Sales tax exemptions are effective at the point of sale for your solar panels. Property tax exemptions let you exclude the value that your solar panels add when calculating how much property tax you need to pay on your home.
  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.
  • Rebates: Rebates, or partial refunds after a purchase, are usually applied before any solar tax credits are calculated. Rebates might be provided by your local utility company, by your county or by your state.

Federal Solar Incentives

Federal solar incentives are likely the first thing that you think of when thinking about solar incentives. It's likely that you've heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit equal to a predetermined percentage of the money you spend on your solar system.

The ITC can be applied to a solar system installed on your primary or secondary residence in the United States. The solar system must have been installed after January 1, 2006, on a property owned by you for you to claim the credit. The ITC originally paid out 30% of all system costs (panels, labor, equipment and accessories), although this amount has fluctuated over the years between 26-30%. The installation date of your solar system will determine what percentage you are eligible for. There is no cap on the amount you can claim.

To better understand how the ITC could apply to you, contact your local Westport solar panel installation expert and request more information.

In August 2022, the ITC (now titled the Clean Energy Credit) was bolstered by the passage of the Inflation Reduction Act. The Clean Energy Credit bolsters the current credit, increasing it up to 30% for solar installation projects started after January 1, 2022, and completed by the end of 2032. After 2032, the credit percentage will see a slight decrease annually until the program expires in 2035. Starting in 2023, the program expansion will also make it easier to get credit for energy storage systems.

State & Local Solar Incentives

There are often state solar incentives available in addition to federal ones. Tax credits, rebates and more may be available at a more local level. The incentives — which might be provided by the state of Massachusetts, or by your county or municipality — could be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Westport

The large number of solar incentives available has helped tremendously increase the adoption of solar energy nationwide over the last 15 years.

We suggest talking to your local Westport solar installation company for more information about these incentives and to make sure that you're getting all the money you can for your solar system.

EcoWatch's Westport, MA Solar Incentives FAQs

My home already has solar panels. Are there any incentives that I qualify for?

If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If you installed your system between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the date of installation. Reaching out to the company that installed your system, or any local Westport solar installer, can help you understand what incentives you qualify for.

What are some environmental benefits of installing solar panels on my home?

You can decrease your carbon footprint by 200 pounds of CO2 annually when you switch to solar panels. This adds up to approximately 4,000 pounds over 20 years. In addition, solar power is a renewable energy source, which means that making the switch reduces the drain on our planet's resources.

Can I use a combination of multiple types of renewable energy to power my home?

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Make sure you discuss your plan with your local Westport solar installation expert. They can help you plan your project and give you an understanding of various incentives that you will or won't qualify for.

Can I claim incentives for adding solar panels to a vacation home, rental property or commercial property?

While we recommend talking to your local solar installer and/or tax professional to fully understand what solar incentives apply to you, many can be claimed on a second home, provided that it is in the United States and owned by you. There may be other incentives available specifically for commercial properties, depending on the specifics.
