Program Performance


The Mass Solar Loan program tracks information on things like solar system cost, size and equipment.

Residents interested in solar can use the below dashboard to explore this information and better understand the economics of installing solar on their homes. The dashboard provides information about solar costs and loan interest rates under the Mass Solar Loan program. It can be customized by geography, installer, lender, equipment or other criteria to compare solar system information across the Commonwealth.

Program History

Mass Solar Loan launched as a $30 million program administered in partnership between the Massachusetts Department of Energy Resources (DOER) and the Massachusetts Clean Energy Center (MassCEC).  Mass Solar Loan connects homeowners interested in solar electricity to solar installers and lenders that have available financing options. Through the program, lenders offer low-interest loans for Massachusetts residents and property owners, including renters and those with moderate incomes or low credit scores. The program is financed through $30 million of Alternative Compliance Payments from the Department of Energy Resources. An additional $10 Million dollars was added to the program in Fall 2017, focusing the available incentives specifically on low or moderate income residents or property owners.
