Solar incentives mitigate the cost of installing solar panels on your home. Financial incentives like these are intended to encourage more people to switch to renewable energy. Different kinds of incentives, including cash back, discounts or credit towards your monthly utility bill, might be available to you. Certain incentives may be handled by the Massachusetts government, by your utility company or by county or municipality, while others are federal. Some solar incentives you might qualify for are:

  • Rebates: Solar companies may help you claim a rebate, or partial refund of your purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. If you receive a rebate, that amount will usually be deducted from your total price before tax credits are calculated.
  • Tax Exemptions: These can come in the form of property tax exemptions, which can let you ignore the value of your solar system when calculating the taxes you pay on your home. They may also include exemptions on sales tax at the time of purchase.
  • Net Metering: Net metering becomes relevant after your solar system is up and running. If you have a net metering agreement with your Boston utility company, the company will subtract the value of the excess energy your solar system produces from your utility bill each month. In some places, this credit is dollar-for-dollar, while in others you may be refunded a percentage of the value.
  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the government.
  • Solar Renewable Energy Certificate (SREC): In general, solar systems that produce more than a specified (generally small) amount of electricity can qualify for SRECs or other performance-based incentives. SRECs and the like are typically given at the state level. When you receive an SREC, you can sell it to your utility company or another buyer, and this is usually considered part of your taxable income.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have some knowledge of. The solar incentive that you may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a specified percentage of the cost of your solar system.

The ITC can be applied to the total cost of installing a solar system, including the panels themselves as well as labor, accessories and equipment. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence that you own, as long as it is located in the United States. 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 claim amount.

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

In August 2022, the Inflation Reduction Act made revisions to the ITC, now called the Clean Energy Credit. The new Clean Energy Credit is valid until 2035. Homeowners can now apply for a 30% credit for solar systems that began installation after January 1, 2022, and are completed by the end of 2032. The total credit will then decrease annually until its expiration. The expansion to the program also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.

State & Local Solar Incentives

Rebates, tax credits and more might be provided at multiple levels. In addition to federal solar incentives, there are often state and local ones, too. These incentives might be handled by your county or municipality, or by the Massachusetts government. Some incentives may be ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Boston

Solar incentives may come from the Massachusetts government, the federal government or your local utility company. The variety of available incentives has facilitated the nationwide growth of solar energy use in the last 15 years. Speaking with your local Boston solar panel installer is the right first step towards making sure you get all the incentives you qualify for when you switch to solar energy.

EcoWatch's Boston, MA Solar Incentives FAQs

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

If your solar panels were installed after January 1, 2022, you may qualify for the newly increased 30% tax credit under the Inflation Reduction Act. If your system was installed between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the year it was installed.

If I trade in my appliances for ones that utilize solar energy, are there any benefits I can claim?

The new Inflation Reduction Act introduces a number of incentives that reward homeowners for making eco-friendly upgrades. Some of these incentives include tax credits and rebates for installing new electric appliances. You can find more details about these incentives here.

Can I receive incentives both towards the initial cost of solar panels, and later as reimbursement?

Yes, you can claim both tax credits and rebates towards the cost of solar panels. Depending on which incentives you are eligible for, they may apply in a different order. Make sure that you talk to your solar installer or a local tax professional to confirm that you are claiming incentives correctly and that you're getting the most money possible.
