Solar Incentives in Massachusetts

Massachusetts residents can save money on their solar panels and installation by taking advantage of the state’s solar incentives. These tax credits and rebates are available to qualifying system owners as part of the Bay State’s push to make better use of solar energy. 

Massachusetts solar incentives include:

  • Solar Massachusetts Renewable Target (SMART) Program: This program allows homeowners to receive payments from their utility company for every kilowatt-hour (kWh) of solar power they create for 10 years. 
  • Residential Renewable Energy Income Tax Credit: Owners or tenants of a residential property located in the commonwealth, who are not a dependent of another taxpayer and who occupies the property as their primary residence, are eligible for a 15% state tax credit on purchased residential solar systems. 
  • Solar Installation Property Tax Exemption: Massachusetts doesn’t make system owners pay property tax on the additional value solar panels add to their home. 
  • Home Solar Project Sales Tax Exemption: This exemption prevents you from paying the state’s 6.25% sales tax on your solar panel system. 
  • Net-metering: Massachusetts participates in net-metering, which allows you to sell your system’s excess energy back to your local utility company.

What To Look For in a Solar Company

Below are some key factors to consider when comparing companies.

Solar Services

Check that the company you’re considering doesn’t just sell solar panels but also installs them. We recommend in-house rather than third-party installation because you’ll likely experience better communication and quality assurance. You’ll also get a more comprehensive labor warranty on the workmanship.

Verify whether the provider only installs solar panels or also installs solar batteries, inverters, chargers, and other equipment. Check for additional offered solar services, including system monitoring, dedicated apps, and energy audits.

Warranties

These are the most common solar warranties you’ll come across:

  • Manufacturer’s warranty (or product warranty): This protects the individual solar panel system components in case of defects.
  • Workmanship warranty: This covers installation in case of poor workmanship or faulty installation materials.
  • Performance (or power production) guarantee: This guarantees the solar system’s output performs as outlined in your contract.

The best companies offer 25-year warranties in each of these cases, though some limit their workmanship warranty to 10 years. We recommend finding a company that provides at least 20 years of coverage for each warranty type.

Payment Options

Most solar companies offer at least two of these solar financing options:

  • Full purchase: Purchasing your system in full gives you immediate ownership and qualifies you for solar incentives. This is the most cost-effective option, as you won’t have to pay extra for interest fees. However, it involves a large amount of cash up-front.
  • Solar loan: A solar loan allows you to pay for your system in monthly installments rather than all at once. You’ll pay more over time due to interest rates, but you’ll still own your system and be able to use solar incentives to save money.
  • Solar lease: Similar to a loan, a solar lease allows you to make set monthly payments to use solar energy. However, you won’t own your system, which disqualifies you from most solar incentives.
  • Power purchase agreement (PPA): A PPA allows you to pay for only the energy you use with no money down, similar to an electricity bill. As with a lease, you won’t own the system or qualify for solar incentives.

We recommend buying your system outright or financing through a loan if it’s in your budget. Be wary of companies that push solar leases or PPAs without being transparent about the fact that these options disqualify you from incentives.

Customer Support

Customer service can make all the difference in your experience. You want a provider that’s friendly, reachable, responsive, and helpful. Companies should provide multiple ways to reach them, such as phone, email, online chat, online portal, or mobile app. They should be responsive across each of these options.

Try calling, emailing, or messaging the provider to see how long it takes to reach the right person. Look at the customer support hours to see if you’ll be able to reach someone on weekends and evenings. Lastly, consider how supportive the customer service team is. A provider that thoroughly answers all of your questions, looks for ways to save you money, and takes the time to get the best product for your needs should be at the top of your list.


How To Get a Solar Quote in Massachusetts

It’s easy to get a solar quote in Massachusetts by following these simple steps:

  • Request a quote: Visit each company’s website and request a quote by phone or online form. When we went through the process online, getting a quote took less than 15 minutes. By phone, it took an average of 20 minutes.
  • Schedule a consultation: Many companies offer in-person or virtual consultations. You’ll review your average energy use, so have your latest electricity bill handy. The consultant will review your roof design and make recommendations for optimal panel placement. They may also advise whether you need any roof repairs or upgrades before installation.
  • Design your system: You’ll create a customized solar system based on the previous assessments. Your options may include solar panels, inverters, components, solar batteries, and electric vehicle (EV) chargers.
  • Review the final quote: Each solar system quote will include full details on system costs, labor expenses, warranty coverage, and financing options. We recommend getting quotes from at least three providers to find the best offer.
