According to the Solar Energy Industries Association, in 2019, Massachusetts had 2,582 MW of solar energy installed, ranking it eighth nationwide. When all solar installations in the state are combined, there is enough energy produced to power 436,415 homes. Discover how Massachusetts’ supportive solar policies and incentives have led to significant solar development in the state.

Massachusetts’ Solar
Report Card


To determine a grade for each state, our researchers and solar experts analyzed data on crucial solar-advancement criteria from the following sources:

We determined a rank from one to 10 for each state in each category. We then combined the scores with the following weights and assigned an overall grade for each state. Our goal is to encourage those considering solar for their homes to get a basic understanding of solar potential in their areas and discover the best opportunities for clean energy available.

How Expensive is Electricity in Massachusetts?

Massachusetts averages $0.22 cents per kWh, according to the U.S. Energy Information Administration, making it the fourth-highest ranking state for electricity prices. In 2018, the state generated nearly 67 percent of its electricity from natural gas, with the rest coming from nuclear power and renewables. The high price of electricity is a major motivator for consumers to convert to residential solar and with approximately 200 days per year of full or partial sun, Massachusetts residents are seeing that switching to solar makes good sense.

Massachusetts Solar Panel Tax Credits & Policies

Since 2002, Massachusetts’ electricity providers have been working to meet and exceed the state’s renewable portfolio standard (RPS). The RPS requires 15 percent of electricity to come from Class I renewable resources by 2020, including a mandated target of 1,600 MW of solar. The path to meet this goal is paved with policies, incentives, grants, and tax benefits for residents and businesses that make the switch to sun-based energy. From the Residential Renewable Energy Income Tax Credit to the Mass Solar Loan Program, home and business owners can benefit from solar.


Photovoltaic Incentive Program – Hudson Light & Power

The utility company Hudson Light & Power offers rebates for the installation of solar panels, for commercial, residential, municipal and industrial customers. Incentives vary based on panel orientation and application and only apply to grid-connected customers.

Revolving Energy Fund – PACE

Allows commercial property owners to secure loans to pay for energy improvements, specifically solar water heat and solar panel systems. Repayment terms are determined by local administrations.

Provides rebates to customers of the utility who install solar panels, for a maximum of incentive of $3,125.

MLP Solar Rebate Program

This program provides a one-time incentive of $1,200 per kW DC of solar PV capacity installed, capped at 50 percent of system cost or $30,000, whichever is less.

Taunton Municipal Lighting Plant – Residential PV Rebate Program

Customers of the plant may be eligible for a rebate for solar panel installations, up to a maximum amount of $4,500 from the rebate amount being a total of $1.20 per watt.

Chicopee Electric Light – Residential Solar Rebate Program

Offers the HELPS program, which provides incentives for installing solar energy systems and energy audits to increase energy efficiency.

HG&E’s Residential Energy Conservation Program

Homeowners can secure up to $10,000 of financial assistance at zero percent interest and repayable over a period of 10 years for residential solar installations.

HG&E’s Commercial Energy Conservation Program

his program provides with capital to make to energy-efficient improvements, offering up to $10,000 of interest-free financial assistance that is repayable over a period of 10 years for commercial solar installations.


Net Metering

State law requires the state’s investor-owned (but not municipal, who can do so on a voluntary basis) utility companies to provide net metering services for generators that create electricity from alternative energy sources.

Solar Easements and Rights Laws

Massachusetts law allows for the creation of solar access contracts, and also prohibits the restriction of solar devices in any way that “unreasonably regulates” or prevents its use. Solar access is not an automatic right, however.

Renewable Energy Trust Fund

Financed by a surcharge on every kilowatt hour paid by all customers of electric utilities, the fund is used to provide loans, grants, rebates, bill and energy production credits, and equity investments to customers, and also supports renewable energy projects.

Interconnection Standards

applied to all forms of electric generation including renewables, as well as to the customers of the state’s owned utilities. The standards also require interconnection tariffs.

Green Power Purchasing Commitment

Requires government agencies to use 15 percent of electricity from renewable sources by 2012, and 30 percent by 2020.

None specifically for residential

Renewable Energy Portfolio Standard (RPS)

Legislation enacted in 1997 requires that all retail energy supplies must provide 15 percent of sales of kW hours from renewable energy resources by 2020.

Solar Renewable Energy Certificates (SREC-II) Program

As per the state’s RPS, solar-electric facilities built after January 1, 2012, can generate SRECs, which can be bought by all electricity supplies to meet their solar RPS requirements. The incentive amount per credit varies according to the market.


Alternative Energy and Energy Conservation Patent Income Tax Deduction

offers a separate personal and corporate income tax deduction for income received by developing a U.S. patent that is considered beneficial for energy conservation or for the development of alternative energy, for up to five years.

Residential Renewable Energy Income Tax Credit
