Installation may not be as expensive as you think.

Whether you want to buy or rent solar panels for your home, there are several state and third-party programs to help you lower your upfront costs.

  • The Massachusetts Solar Loan Program includes an interest rate buy-down, income-based loan support, and a loan loss reserve for qualified programs to help you get started.
  • Lease your panels or sign a power purchase agreement (PPA) through a Third-Party Owner (TPO).
    • The TPO will install panels at your property, and then you buy the electricity generated at a below-market rate to save money.
    • Additionally, there is often no upfront cost associated with a TPO, and they are responsible for any future maintenance.

Federal and state tax incentives lower your costs.

A federal tax credit allows you to deduct up to 26% of the cost of a solar panel system from your taxes, although this percentage will decrease in 2021.2 In Massachusetts, you can also receive 15% of the system cost as a credit against your state income tax, up to $1,000. Additionally, Massachusetts also has no sales or property taxes associated with your solar installation.

You can reduce your environmental impact while supporting an energy saving industry.

Solar energy reduces carbon emissions and other pollutants by generating power from a renewable source.

With the solar industry growing rapidly, each and every panel installation supports your local solar companies, the jobs they create and the energy savings they help provide.

Consider community solar

If you rent your home or rooftop solar isn't an option for you, community solar may be the perfect alternative.

In a community solar program, you receive energy from a large shared solar panel system located nearby that generates enough energy to provide net savings to all participants.

What is net metering?

Net metering allows residential customers to receive credits for solar generation even if they do not line up directly with their home energy consumption. Through this process you'll also receive credits for selling excess power back to the utility.

How does the SMART program work?

The Solar Massachusetts Renewable Target (SMART) program compensates eligible system owners with monthly payments from their electric utility for 10 years of solar production. Alternative on-bill credits are available through SMART as an alternative to net metering as well.

What system maintenance is required?

Most solar PV systems require little or no maintenance by the homeowner, aside from ensuring the panels remain unobstructed as much as possible.
