The Comprehensive Guide to Solar Energy in Massachusetts: Illuminating the Bay State with Clean Power


Massachusetts, the Bay State, is leading the charge in renewable energy adoption and has become a trailblazer in the solar industry. With a strong commitment to combating climate change and promoting sustainable energy solutions, Massachusetts offers a wealth of opportunities for residents and businesses to harness the power of the sun. In this comprehensive guide, we will delve into everything you need to know about solar energy in Massachusetts, including the cost of solar installations, available tax breaks and incentives, the number of solar companies, and the state’s vision for a greener and more sustainable future.

Solar Potential in Massachusetts

Despite its northern location, Massachusetts has a surprisingly high solar potential due to its clear skies and ample sunlight. The state’s latitude may receive fewer hours of sunlight compared to southern states, but Massachusetts’ solar capacity is still substantial. The commitment to renewable energy and the availability of state incentives contribute to the growing popularity of solar power in the Bay State.

The Cost of Solar Installations in Massachusetts

The cost of solar installations in Massachusetts can vary based on various factors, such as the size of the system, the type of solar panels used, and the complexity of the installation. As of my last update in September 2021, the average cost of a residential solar PV system in Massachusetts ranged from $2.50 to $3.50 per watt before any financial incentives. For a typical 6 kW solar system, this would amount to around $15,000 to $21,000 before incentives.

It’s important to note that the cost of solar installations has been steadily declining over the years, making solar energy increasingly affordable for Massachusetts residents and businesses. In addition to the decreasing costs, federal and state incentives play a significant role in reducing the upfront expenses of adopting solar power.

Solar Tax Breaks and Incentives

Massachusetts offers a range of tax breaks and incentives to promote solar energy adoption and encourage the transition to clean energy. Some of the key incentives include:

Federal Solar Investment Tax Credit (ITC):

The Federal ITC provides a tax credit for a percentage of the total solar system cost for both residential and commercial installations. As of my last update, the ITC offered a 26% tax credit, but this percentage may have changed since then. It’s essential to check the latest updates to determine the current percentage.

Massachusetts Personal Income Tax Credit:

The state provides a personal income tax credit for residential solar installations. The credit can be claimed over two years and helps reduce the overall cost of going solar.

Massachusetts Solar Renewable Energy Certificates (SRECs):

The SREC program allows solar system owners to earn certificates for every megawatt-hour (MWh) of electricity their solar systems generate. These certificates can be sold to utilities or other entities to meet their renewable energy targets, providing an additional source of revenue for solar system owners.

Property Tax Exemption:

Solar installations in Massachusetts are exempt from property tax assessments, ensuring that homeowners and businesses do not face an increase in property taxes due to their solar systems.

Net Metering:

Massachusetts has a robust net metering policy that allows solar system owners to receive credits for any excess electricity they generate and feed back into the grid. These credits can offset the electricity consumed from the grid during periods of low solar generation, effectively reducing electricity bills.

Solar Loans and Financing Options:

Several loan and financing programs are available to help Massachusetts residents and businesses overcome the upfront costs of solar installations. These programs offer low-interest loans and attractive financing options to make solar energy more accessible and affordable.

The Rise of Solar Companies in Massachusetts

Massachusetts has seen a surge in the number of solar companies operating within the state. These companies offer a wide range of services, from solar system design and installation to maintenance and monitoring. The growing number of solar companies has created a competitive market, providing consumers with diverse options for their solar needs.

As you explore different solar companies in Massachusetts, consider factors such as experience, customer reviews, certifications, and warranties. Choosing a reputable and experienced installer is crucial to ensure the proper design, installation, and maintenance of your solar system.

Massachusetts’ Vision for a Sustainable Future

Massachusetts has set ambitious renewable energy goals to combat climate change and reduce greenhouse gas emissions. The state is actively pursuing a sustainable future by enacting policies and initiatives to promote renewable energy adoption. Massachusetts’ Renewable Portfolio Standard (RPS) sets targets for the percentage of electricity generated from renewable sources, encouraging the growth of solar and other clean energy technologies.

The Massachusetts Clean Energy Center (MassCEC) plays a vital role in advancing the state’s clean energy agenda. The MassCEC collaborates with stakeholders, businesses, and communities to foster the growth of clean energy industries, including solar, and drive innovation in the renewable energy sector.


Massachusetts, with its commitment to sustainability and renewable energy, presents a promising landscape for solar power adoption. Despite its northern latitude, the Bay State’s solar potential is substantial, and advancements in technology and supportive policies have made solar energy more affordable and accessible for residents and businesses.

With a wealth of tax breaks, incentives, and financing options available, Massachusetts residents can embrace solar power to lower energy costs and contribute to a cleaner and greener environment. As the number of solar companies continues to grow, consumers have the opportunity to choose from reputable installers that can guide them through the process of harnessing the power of the sun.

By embracing solar energy, Massachusetts can illuminate its path towards a more sustainable future, reducing its reliance on fossil fuels and making significant strides in the fight against climate change. Through collective efforts and a shared commitment to renewable energy, the Bay State can lead the nation towards a brighter and greener future for generations to come.
