Solar incentives are designed to make renewable energy usage more affordable via financial incentives for individuals who install solar panels on their homes. Different kinds of incentives, such as cash back, discounts or credit towards your monthly utility bill, might be available to you. Certain incentives may be provided via the Massachusetts government, by your utility company or by county or municipality, while other incentives are federal. Categories of solar incentives include:

  • Net Metering: Don't forget to speak with your Waltham utility company about signing a net metering contract. This allows you to get a 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, how much income tax you owe the federal government. These differ from tax deductions.
  • Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives are normally handled by your state government. Once your solar system meets a predetermined threshold (normally a small amount of energy production), you are eligible to receive SRECs that can then be sold to your utility company or other buyers. The money you receive is usually considered part of your taxable income.
  • Tax Exemptions: These could come in the form of property tax exemptions, which can let you ignore the value of your solar system when paying taxes on your house. You could also look for exemptions on sales tax at the time of purchase.
  • Rebates: Solar rebates may be provided by your local utility company, or by your state or county. These rebates work as partial refunds that are applied after you pay for a solar system and before tax credits are calculated.

Federal Solar Incentives

Federal solar incentives are likely the first thing that you think of when you think about solar incentives. 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 predetermined percentage of the cost of your solar system.

The ITC was originally for 30% of the cost of solar system installation, although it has fluctuated slightly over the last few years between 26-30%. The installation date of your solar system will determine what percentage you qualify for. The cost of installation includes the panels themselves as well as the cost of accessories, equipment and labor. There is no maximum amount you can claim. The ITC can be applied to solar panels installed after January 1, 2006, on your primary or secondary residence. The residence must be in the United States and owned by you.

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

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. Homeowners are now eligible for a credit of 30% of the total solar system installation costs for projects that began after January 1, 2022, and will be finished by the end of 2032. The percentage will then begin to decrease annually until the Clean Energy Credit expires in 2035. Beginning in 2023, it will also be easier to get credits for energy storage systems under this new program.

More information about the new Inflation Reduction Act can be found here. The best way to understand how the new Clean Energy Credit might apply to you is to get in touch with your local Waltham solar panel company.

State & Local Solar Incentives

Some solar incentives may be provided at the state and local level. As with federal incentives, these may include rebates, tax credits and more. These incentives might be given out by the Massachusetts government, or by your county or municipality. Certain incentives are ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Waltham

There are many kinds of solar incentives: those provided by local utility companies, those provided by the federal government and those given by the Massachusetts government, to name a few. The use of solar energy has grown enormously in the last 15 years, partially thanks to these incentives. Your local Waltham solar panel installation expert can give you more information about which incentives you might qualify for, and get you started on the path to switching to renewable energy today.

EcoWatch's Waltham, MA Solar Incentives FAQs

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

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

How long until the federal solar tax credit ends?

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

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

The new Inflation Reduction Act creates a variety of new financial incentives for making eco-friendly improvements to your home. More details regarding these incentives, including information about incentives for purchasing new appliances, can be found here.

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

The order that incentives will be applied in might vary depending on which incentives you are claiming but usually yes, you can receive multiple types of incentives for your solar project. Check with your solar installer or a local tax professional to confirm you are claiming all possible incentives and applying them in the correct order.
