Solar incentives are meant to help mitigate the cost of installing a solar panel system on your home. These financial incentives are intended to encourage more Americans to switch their home over to renewable energy. Various kinds of incentives, such as cash back, discounts or credit towards your monthly utility bill, might be available to you. Some incentives may be provided via the Massachusetts government, by your utility company or by county or municipality, while others are federal. Categories of solar incentives include:

  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar system. States or counties will also offer limited-time rebates at various times. The value of a rebate will usually come off your total price before tax credits are calculated.
  • Tax Exemptions: Tax exemptions can come in one of two forms. The first is sales tax exemption, which is applied at the time you purchase your solar panels. The second is property tax exemption. This allows you to ignore the added value of your solar system when paying property tax on your home.
  • Net Metering: Make sure you speak with your Boston utility company about signing a net metering contract. This allows you to receive credit towards your utility bill every month for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Credits: Tax credits lower, dollar-for-dollar, the amount of income tax you owe the government. Tax credits differ from tax deductions.
  • Solar Renewable Energy Certificate (SREC): SRECs are credits that can be sold to your utility company (or other buyers) for cash that normally counts as part of your taxable income. Typically, a certain (small) threshold of energy production must be met before your solar system qualifies for SRECs or similar performance-based incentives. SRECs and similar incentives are normally handled by your state government.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have heard of. You might have heard of the Federal Solar Investment Tax Credit, or ITC. The ITC is a tax credit that reduces your taxes by a predetermined percentage of the money you spend on solar panels for your home.

The ITC can be applied to the total cost of installing solar panels, including the panels themselves as well as equipment, labor and accessories. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence that you own and that is located in the United States. From its original value of 30% of the total cost, the credit has fluctuated slightly between 26-30%, and you may qualify for varying percentages depending on when your project was completed. There is no maximum amount you can claim.

To find out exactly how much the ITC could save you, talk to your local Boston solar panel installation expert.

In August 2022, the ITC (now called the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. The Clean Energy Credit is valid until 2035. Your solar installation project undertaken between 2022 and 2032 may qualify for a 30% tax credit. This amount will then decrease slightly on a yearly basis until the end of the current program. Starting in 2023, it will also be easier to obtain credits for energy storage systems under this new program.

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. Certain incentives are ongoing, while others are available for a limited time. They might be offered by the Massachusetts government, or by your county or municipality.

Next Steps for Installing Solar in Boston

You can apply for solar incentives from the federal government and the Massachusetts government, as well as from your local utility company. The increased availability of solar initiatives in the past 15 years has helped greatly increase nationwide adoption of solar energy. Speak with your local solar panel installer today to find out more information and to save as much money as possible on a solar system for your Boston home.
