The term "solar incentives" covers a wide 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. Solar incentives may include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are provided by the federal government, some by the state of Massachusetts and some by your specific utility company, county or municipality. Types of solar incentives might include:

  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.
  • Rebates: Solar rebates can be provided by your local utility company, or by your state or county. These rebates are essentially cash back that is applied after your purchase of solar panels and before tax credits are calculated.
  • Net Metering: Be sure to talk to your Westborough utility company about signing a net metering contract. This will allow you to receive credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: Tax exemptions can come in one of two forms. First, there is sales tax exemption, which is applied when you purchase solar panels. The second is property tax exemption. This allows you to exclude the added value of your solar system when paying property tax on your house.
  • Solar Renewable Energy Certificate (SREC): SRECs and similar performance-based incentives are generally handled by your state government. Once your solar panel system meets a predetermined threshold (normally a small amount of energy production), you can receive SRECs that can then be sold to your utility company or other buyers. The money you make is usually considered part of your taxable income.

Federal Solar Incentives

When someone says "solar incentives," you probably think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is the best-known federal solar incentive. The ITC offers a tax credit for a set percentage of your solar system's cost.

The ITC covers solar systems installed after January 1, 2006, and allows you to deduct from your taxes a percentage of the total cost of solar panels, labor, equipment and accessories. You can claim this credit for solar panels installed on a primary or secondary residence that you own in the United States. Originally, you could claim 30% of the total cost, although depending on when the project was completed, your credit may range from 26-30%. There is no maximum claim amount.

Have questions about how the ITC applies to your specific situation? Contact your local Westborough solar panel installer to get more information.

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as renaming it to the Clean Energy Credit). For solar system installations that begin after January 1, 2022, and are completed by the end of 2032, homeowners can receive a credit for 30% of the total cost. After 2033, the percentage will decrease annually until the Clean Energy Credit expires in 2035. The program expansion also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.

More information about the new Inflation Reduction Act can be found here. To understand how the new Clean Energy Credit might apply to you, speak with your local Westborough solar installation expert.

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. These incentives may be provided by your county or municipality, or by the Massachusetts government. Some are ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Westborough

Nationwide solar energy use has significantly increased in the last 15 years, in part due to the proliferation of solar incentives. You might receive these incentives from the Massachusetts government, the federal government or your local utility company. Speaking with your local Westborough solar panel installer is an excellent first step towards getting the most money possible when you switch to solar energy.

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 your solar panels. Depending on which incentives you are applying for, they may apply in a different order. Be sure to talk to your solar installer or a local tax professional to confirm that you are claiming the correct incentives and getting the most money possible.
