Solar incentives are designed to encourage homeowners to switch to renewable energy by offering incentives meant to lower the financial burden of solar panel installation and use. Various kinds of incentives, including discounts, cash back or monthly utility bill credits, may be available to you. Some incentives may be provided via the Massachusetts government, by your utility company or by county or municipality, while other incentives are federal. You might qualify for any of the following types of solar incentives:

  • Net Metering: Net metering factors in after your solar panels are up and running. If you have a net metering agreement in place with your Williamstown utility company, they will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in other areas you might be refunded a percentage of the value.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the federal government.
  • Rebates: Solar rebates might be provided by your county or state, or by your local utility company. These rebates work as partial refunds that are applied after you pay for a solar system and before tax credits are calculated.
  • Solar Renewable Energy Certificate (SREC): SRECs and similar performance-based incentives are normally handled by your state government. Once your solar system meets the threshold (typically a small amount of energy production), you are eligible to receive SRECs that you can then sell to your utility company or other buyers. The money you receive from the sale is usually considered part of your taxable income.
  • Tax Exemptions: Your solar panels could qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions let you exclude the value that solar panels add when calculating property taxes on your home.

Federal Solar Incentives

When thinking about solar incentives, federal incentives are likely the first thing that comes to mind. The solar incentive that you're most familiar with is probably the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a predetermined percentage of your solar system's cost.

The ITC can be applied to the total cost of solar system installation, including the panels themselves as well as accessories, labor and equipment. You can claim this credit 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. The tax credit ranges from 26-30% of total costs depending on when your project was completed. There is no maximum claim amount.

Curious how the ITC might apply to your specific situation? Reach out to your local Williamstown solar panel installer to get more information.

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now called the Clean Energy Credit. Homeowners are now eligible for a credit of 30% of the total solar system installation costs for projects started after January 1, 2022 and completed before the end of 2032. The credit percentage will then begin to decrease yearly until the Clean Energy Credit expires in 2035. The program expansion also makes it easier to get credit for energy storage systems, starting in 2023.

More information about the new Inflation Reduction Act can be found here. Your local Williamstown solar panel company can answer any questions you have and explain how the new Clean Energy Credit applies to you.

State & Local Solar Incentives

Rebates, tax credits and more can be provided at multiple levels. Along with federal solar incentives, there are often state and local ones, too. These incentives — which might be provided by your county or municipality, or by the state of Massachusetts — might be offered for only a limited time, or on an ongoing basis.

EcoWatch's Williamstown, MA Solar Incentives FAQs

If I already have a solar system installed on my house, can I still claim incentives?

If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If you had your system installed between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the year it was installed. Speaking with the company that installed your system, or any local Williamstown solar installer, can help you learn what incentives you might want to apply for.

What are the environmental benefits of switching to solar?

You can reduce your carbon footprint by 200 pounds of CO2 a year when you install solar panels. This adds up to around 4,000 pounds in 20 years. Solar is also a renewable energy source, meaning that switching your home over reduces the drain on our planet's resources.

How long until the federal solar tax credit ends?

The Clean Energy Credit (formerly named the federal solar tax credit, or the ITC), is scheduled to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

I want to change out my appliances for ones that are more energy-efficient. Are there any benefits I can claim?

The new Inflation Reduction Act provides multiple incentives meant to reward homeowners who make eco-friendly upgrades. Some incentives include tax credits and rebates for installing new electric appliances. You can find more details about these incentives here.

Can I apply for incentives both towards the up-front cost of solar panels, and later as reimbursement?

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