Solar incentives are meant to help mitigate the cost of installing a solar panel system on your home. Financial incentives like these are in place to encourage more people to make the switch to renewable energy. Different types of incentives, including cash back, discounts or credit towards your monthly utility bill, may be available to you. Some incentives may be offered by the state of Massachusetts, by your utility company or by county or municipality, while others are federal. You might qualify for any of the following types of solar incentives:

  • Net Metering: Be sure to talk to your Waltham utility company about signing a net metering agreement. This allows you to receive credit towards your utility bill every month 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 Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government. (This is different from a tax deduction.)
  • Solar Renewable Energy Certificate (SREC): SRECs and similar other performance-based incentives might be available to you if you have a solar system that produces over a specified (usually small) amount of electricity. Performance-based incentives are usually handled by the state government. You can sell SRECs to your utility company or other buyers, and the money you make is usually considered part of your taxable income.
  • Tax Exemptions: Sales tax exemptions are effective at the time of purchase for your solar panels. Property tax exemptions allow you to ignore the value that your solar panels add when calculating how much property tax you need to pay.
  • Rebates: Rebates, or partial refunds after a purchase, are normally applied prior to any solar tax credits being calculated. Rebates might be provided by your local utility company, by your county or by your state.

Federal Solar Incentives

Federal solar incentives are likely to be the first thing that you think of when you think about solar incentives. You may have heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit that reduces your taxes by a predetermined percentage of the money you spend installing solar panels.

The ITC can be applied to solar systems installed after January 1, 2006, and lets you deduct from your taxes a percentage of the total cost of solar panels, equipment, labor and accessories. This credit can apply towards a solar panel system installed on a primary or secondary residence in the United States that you own. The original claim amount was 30% of the total cost, although depending on when the project was completed, your credit may range from 26-30%. There is no maximum amount you can claim.

Reaching out to your local Waltham solar panel installer is the best way to learn more about how the ITC may apply to you.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now dubbed the Clean Energy Credit. The new Clean Energy Credit is valid until 2035. Homeowners can now apply for a 30% credit for solar systems installed between January 1, 2022, and December 31, 2032. This credit will then be decreased by a few percentage points every year until the date of expiration. The expansion also makes credits for energy storage systems even easier to claim, starting in 2023.

State & Local Solar Incentives

Some solar incentives are often also offered at the local or state level. Similar to federal incentives, these can include rebates, tax credits and more. These incentives may be handled by your county or municipality, or by the Massachusetts government. Certain incentives are ongoing, while others are available for a limited time.

EcoWatch's Waltham, MA Solar Incentives FAQs

What are some environmental benefits of adding solar panels to my home?

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

How long until the federal solar tax credit ends?

The federal solar tax credit, formerly known as the ITC and now named the Clean Energy Credit, is set to end on January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.

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

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

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

The order your incentives will be applied in may vary depending on which incentives you receive but usually yes, you can claim multiple types of incentives for your solar project. Speak to your solar installer or a local tax professional to verify you are claiming all the incentives you're eligible for and applying them in the correct order.
