The phrase "solar incentives" covers a range of financial incentives implemented to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. Incentives may include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are handled federally, while others are offered by the state of Massachusetts or by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Tax Exemptions: Sales tax exemptions are applied at the point of sale for your solar panels. Property tax exemptions allow you to ignore the value added by your solar system when you're calculating the amount of property tax you need to pay.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar system. Counties or states will also sometimes offer limited-time rebates. Any rebates you receive will usually come off the total price before any tax credits are calculated.
  • Net Metering: Net metering factors in once your solar panels are up and running. If you have in place a net metering agreement with your Sudbury utility company, it will subtract the value of the excess energy your solar system produces from your utility bill each month. In some areas, this is a dollar-for-dollar credit, while in other places you might receive a refund equivalent to a percentage of the value.
  • Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives might be available to you if your solar system produces over a specified (typically small) amount of electricity. Performance-based incentives are typically handled at the state level. You can sell any SRECs you have to your utility company or other buyers, and the money you make is normally considered part of your taxable income.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives are likely the first thing that comes to mind. A federal incentive that most people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a given percentage of the cost of your solar system.

The ITC applies to the total cost of installing a solar system, including the panels themselves as well as labor, accessories and equipment. You can claim this credit for panels installed after January 1, 2006, on a primary or secondary residence located in the United States that you own. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum amount you can claim.

To know exactly how much money the ITC could save you, contact your local Sudbury solar panel installer.

In August 2022, the ITC (now referred to as the Clean Energy Credit) was bolstered by the passage of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. Homeowners are now eligible for a 30% credit for solar systems installed between 2022 and 2032. This new credit will then see a slight annual decrease until it expires. Beginning in 2023, it will also be easier to claim credits for energy storage systems under the new laws.

More information about the new Inflation Reduction Act can be found here. The best way to fully understand how the new Clean Energy Credit applies to you is to speak with your local Sudbury solar panel company directly.

State & Local Solar Incentives

Tax credits, rebates and more can be provided at multiple levels. Along with federal solar incentives, there are often state and local ones as well. Incentives may be provided by your county or municipality, or by the state of Massachusetts. Some incentives may be available for only a limited time, while others are ongoing.

Next Steps for Installing Solar in Sudbury

The variety of available solar incentives has helped tremendously increase the adoption of solar energy nationwide over the last 15 years. You can get solar incentives from your local utility company, the Massachusetts government or the federal government. When you're prepared to make the change to solar energy, calling your local Sudbury solar panel installation expert is a great first step.

EcoWatch's Sudbury, MA Solar Incentives FAQs

I already have solar panels. Are there any incentives that I qualify for?

You should plan to talk to the company that installed your system – or call a local Sudbury solar installer — to clarify which incentives you may qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

How much will a solar system save me on my electric bill in Sudbury annually?

After adding solar panels to your Sudbury home, you can anticipate savings of approximately $1,116.06 per year, or approximately $21,205.15 over 20 years.

What are some environmental benefits of adding solar panels to my home?

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

When does the federal solar tax credit end?

The Clean Energy Credit (previously called the federal solar tax credit, or the ITC), currently ends on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.
