Solar incentives mitigate the cost of installing a solar panel system on your home. Financial incentives like these are intended to encourage more people to convert their home partially or fully to renewable energy. Incentives could include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are handled federally, while others are offered by the state of Massachusetts or by your specific utility company, county or municipality. Some broad categories of solar incentives include:

  • Solar Renewable Energy Certificate (SREC): SRECs and similar performance-based incentives are usually handled by your state government. Once your solar system meets the threshold (typically a small amount of energy production), you can receive SRECs that you can then sell to your utility company or other buyers. The money you make is usually considered part of your taxable income.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, the total amount of tax you owe the government. These are different from tax deductions.
  • Tax Exemptions: Sales tax exemptions go into effect at the point of sale for your solar panels. Property tax exemptions let you ignore the value that your solar panels add when calculating the amount of property tax you need to pay on your home.
  • Rebates: Rebates, or partial refunds after a purchase, are typically given before any solar tax credits are calculated. Solar rebates may be provided by your local utility company, by your county or by your state.
  • Net Metering: Net metering is an incentive you can get after your solar system is up and running. If you have a net metering agreement with your Dartmouth utility company, the company will subtract the value of the excess energy your solar system produces from your utility bill each month. In some areas, this credit is dollar-for-dollar, while in others you might make back a percentage of the value.

Federal Solar Incentives

Federal solar incentives are likely the first thing that you think of when thinking about solar incentives. One of the incentives that most people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a given percentage of the cost of your solar system.

The ITC applies to a solar system installed on your primary or secondary residence in the United States. The solar system has to have been installed on a property you own after January 1, 2006, for you to be eligible for the credit. Originally, the ITC covered 30% of all costs (panels, accessories, labor and equipment), although the covered amount has fluctuated over time between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the claim amount.

To more fully understand how the ITC will apply to your situation, call your local Dartmouth solar panel installer and request more information.

The ITC has been renewed and expanded following the passage of the Inflation Reduction Act in August 2022. It's also 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 on or after January 1, 2022, and will be done by December 31, 2032. This new credit will then be decreased by a few percentage points every year until it expires. The expansion also makes it easier to get credit for energy storage systems, starting in 2023.

State & Local Solar Incentives

Rebates, tax credits and more can be claimed at multiple levels. On top of federal solar incentives, there are often state and local ones, too. These incentives may be distributed by your county or municipality, or by the Massachusetts government. Certain incentives are available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Dartmouth

Solar energy use nationwide has significantly increased in the last 15 years, in part due to the proliferation of solar incentives. You can obtain these incentives from your local utility company, the Massachusetts government or the federal government. We suggest talking to your local Dartmouth solar installation expert for more information about these incentives and to be sure that you're getting the most money possible for your solar system.

EcoWatch's Dartmouth, MA Solar Incentives FAQs

How can I learn if I qualify for specific solar incentives?

It's a good idea to talk to your local Dartmouth solar installer to get an understanding of which incentives your project may qualify for. Usually, solar incentives apply to new solar systems installed on a property you own (in the U.S.) between the dates specified by the incentive. Some incentives, such as those given by the state of Massachusetts, might have additional requirements.

How much can I save on my electric bill annually if I add solar panels to my Dartmouth home?

On average, Dartmouth homeowners who install solar panels save around $1,202.75 per year, or about $22,852.34 over 20 years after they make the switch.

What are the environmental benefits of switching to solar?

You can decrease your carbon footprint by 200 pounds of CO2 annually by installing solar panels. This adds up to roughly 4,000 pounds over 20 years. Solar is also a renewable energy source, which means that making the switch reduces the drain on our planet's resources.

Can I claim 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 eligible for but usually yes, you can receive multiple types of incentives for your solar project. Speak to your solar installer or a local tax professional to make sure you are claiming all the incentives you qualify for and applying them in the correct order.

Can I use a combination of multiple types of renewable energy to power my home?

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Be sure to discuss your ideas with your local Dartmouth solar installation expert. They can help you with the plan for your project and also help you understand the various incentives that you might or might not qualify for.
