Federal Solar Incentives: The Investment Tax Credit (ITC)
The most significant financial incentive for homeowners nationwide is the federal Solar Investment Tax Credit (ITC). This is not a deduction but a dollar-for-dollar credit that directly reduces the amount of federal income tax you owe.
- Credit Amount: For systems installed between 2022 and 2032, the ITC allows you to claim 30% of the total cost of your solar energy system.
- Eligibility: You must own your home and the solar panel system. The credit applies to the full cost, including panels, inverters, racking, labor, and even eligible battery storage systems.
- How to Claim: You’ll file IRS Form 5695 with your federal tax return for the year your system was installed. If the credit is larger than your tax liability, you can roll the remaining amount over.
- Impact: On a $25,000 solar system, the 30% ITC provides a $7,500 credit, effectively lowering your net cost to just $17,500.
Massachusetts’ State & Local Solar Incentives

Solar Massachusetts Renewable Target (SMART) Program
- How it Works: The SMART program is a tariff-based incentive that pays solar owners a fixed rate per kilowatt-hour (kWh) for all the solar energy their system produces for a period of 10 years. You receive a monthly check or direct deposit from your utility company (like Eversource or National Grid). The rate you receive is determined by a number of factors, including your utility and the size of your system.
- Impact: This program creates a predictable, long-term income stream that goes directly into your pocket. It significantly enhances the financial return of your solar investment, often shortening the payback period by several years.
Massachusetts Solar Energy Property Tax Exemption
- How it Works: Massachusetts law provides a 100% property tax exemption for the value added to a home by a solar energy system. While solar panels increase your home’s value, this exemption ensures your annual property tax bill will not go up.
- Impact: This is a significant long-term benefit that saves you hundreds of dollars every year for the life of your system.
Massachusetts Residential Clean Energy Income Tax Credit
- How it Works: This state-level tax credit allows you to claim 15% of your total solar system cost, up to a maximum of $1,000, on your Massachusetts state income tax return.
- Impact: This provides an additional, direct reduction in your tax liability, further lowering your net cost of going solar.
Massachusetts Sales Tax Exemption
- How it Works: When you purchase a solar panel system in Massachusetts, all equipment is exempt from the state’s 6.25% sales tax.
- Impact: This provides an immediate, upfront cost reduction. On a $25,000 system, this exemption saves you $1,562.50 right off the bat.
Utility-Specific Solar Programs in Massachusetts
Net Metering
- How it Works: Net metering is a critical policy that ensures you get full value for every kWh your system produces. When your panels generate more power than you are using, the excess is sent to the grid, and you receive a credit on your bill from your utility.
- Impact: Net metering maximizes your bill savings and works in tandem with the SMART program. While SMART pays you for all the energy you produce, net metering ensures you also get the full retail value credit for any energy you don’t use yourself.
