The phrase "solar incentives" refers to financial incentives designed to encourage increased use of renewable energy by making installing and using solar panels more affordable. Different types of incentives, such as discounts, cash back or credit towards your monthly utility bill, may be available to you. Certain incentives may be offered by the Massachusetts government, by your utility company or by county or municipality, while other incentives are federal. Some broad categories of solar incentives include:

  • Tax Exemptions: Tax exemptions may come in one of two forms. The first is sales tax exemption, applied when you purchase 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: Net metering factors in once your solar panels are up and running. If you've signed a net metering agreement with your Somerville 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 receive a refund equivalent to a percentage of the value.
  • Solar Renewable Energy Certificate (SREC): SRECs can be sold to your utility company (or other buyers) for cash that typically becomes part of your taxable income. In most cases, you must meet a certain (small) threshold of energy production before your solar system qualifies for SRECs or other performance-based incentives. These kinds of incentives are normally handled by your state government.
  • Rebates: A rebate is a partial refund given after you've purchased your solar panels. These could be offered by your local utility company, your county or your state. The rebates are usually applied before tax credits are calculated.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, how much income tax you owe the federal government. Tax credits are different from tax deductions.

Federal Solar Incentives

When someone says "solar incentives," you probably think of federal incentives first. One of the incentives many people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specific percentage of your solar system's cost.

The ITC can be credited towards the value of a solar system installed on your primary or secondary residence in the United States. The solar panels must have been installed after January 1, 2006 on a property owned by you for you to claim the credit. Initially, the ITC applied to 30% of all system installation costs (panels, labor, equipment and accessories), although this amount has fluctuated over the last few years between 26-30%. The installation date of your solar system will determine what percentage you are eligible for. There is no cap on the amount you can claim.

Talking to your local Somerville solar panel installer is the best way to learn more about how the ITC applies to you.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passing of the Inflation Reduction Act. The Clean Energy Credit bolsters the current credit, increasing it up to 30% for solar systems installed between 2022 and 2032. After 2032, the percentage will see a slight decrease annually until the end of the program in 2035. Starting in 2023, the program expansion will also make credits for energy storage systems even easier to claim.

State & Local Solar Incentives

Some solar incentives are often also provided by state and local governments. As with federal incentives, these could include tax credits, rebates and more. These solar incentives — which may be provided by the state of Massachusetts, or by your county or municipality — may be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Somerville

The expanding number of available solar incentives has enormously increased the use of solar power nationwide over the past 15 years. You can get solar incentives from the Massachusetts government, the federal government or your local utility company. We recommend talking to your local Somerville solar installation expert to learn more about these incentives and to make sure that you're getting the largest number possible for your solar system.

EcoWatch's Somerville, MA Solar Incentives FAQs

If I already have solar panels, can I still claim incentives?

If your solar panels were 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 solar system, or any local Somerville solar installer, can help you learn more about what incentives you qualify for.

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

You can reduce your carbon footprint by 200 pounds of CO2 annually by installing solar panels. This adds up to roughly 4,000 pounds in 20 years. In addition, solar power is a renewable energy source, meaning that making the switch lessens the drain on our planet's resources.

Can I apply for 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 solar panels. Depending on which incentives you are claiming, they may apply in a different order. Be sure to speak with your solar installer or a local tax professional to confirm that you are claiming the correct incentives and that you're getting the most money you can.

Can I use a combination of solar and another type of renewable energy to power my home?

You can use multiple types of renewable energy, or a combination of renewable and non-renewable energy, to power your home. Be sure to talk through your plan with your local Somerville solar installation expert. They can help you with the plan for your project and educate you on the various incentives that you might or might not qualify for.
