Federal tax credits, state programs, and utility rebates for solar, battery storage, and EV charging, for every New England state. No jargon and no sales pitch: what's available, what it's worth, and where to verify it.
No obligation. We'll reach out within 24 hours.
For two decades the federal government paid homeowners back a serious chunk of their clean energy investment. The Residential Clean Energy Credit (Section 25D) started with the Energy Policy Act of 2005 and grew from there. The Inflation Reduction Act of 2022 set it at an uncapped 30% of system cost, added home batteries, and scheduled it to run through 2032. Then Washington changed course: the One Big Beautiful Bill Act, signed July 4, 2025, ended it seven years early. Systems completed after December 31, 2025 no longer qualify, and as of July 2026 no bill restoring it has passed.
The one everyone knew: an uncapped 30% federal income tax credit on solar, home batteries (3 kWh+), and geothermal. If your system was installed and running in 2025, you can still claim it on your 2025 return, and unused credit carries forward.
Covered 30% of home EV charger equipment and installation, up to $1,000. Chargers placed in service before July 1, 2026 can still be claimed when you file your 2026 return.
Both federal EV purchase credits ended for vehicles acquired after September 30, 2025. State rebates like MOR-EV, CHEAPR, DRIVE EV, and Efficiency Maine's are now the money that matters.
What still works for homeowners: leased or third-party-owned solar can still qualify for the commercial credit (through its own deadlines), with savings passed through in your rate, and the state and utility programs below are now where most of the money is. We're electricians, not tax advisors: confirm anything tax-related with your tax professional.
Tap your state to see current programs for solar, battery storage, and EV charging. This guide is educational: amounts and availability change, so every program links to its official page. Verify there (or ask us) before counting on a number.
The state's flagship solar program, fully operational since July 8, 2026. Home systems up to 25 kW earn a flat payment on every kilowatt-hour produced, on top of your electric bill savings, for 20 years.
Verify at mass.gov →Massachusetts kept its own solar tax credit after the federal one died. Claim it on Schedule EC for your primary residence; unused credit carries over up to three years.
Verify at mass.gov →Eversource, National Grid, and Unitil pay home battery owners for helping the grid on hot afternoons (recently around $275 per kW-summer, though rates vary by utility and year). Your battery still covers outages.
Verify at masssave.com →Exported power earns bill credits, separate from (and stackable with) SMART. State regulators opened a review of credit values in late 2025, but no changes were adopted as of July 2026.
Verify at mass.gov →Residential solar equipment is exempt from state sales tax, and the value it adds to your home is exempt from property tax for 20 years.
With the federal EV credit gone, MOR-EV is the main event: rebates on new battery-electric vehicles (MSRP up to $55,000), with larger amounts for income-qualified buyers and trade-ins.
Verify at mor-ev.org →Every CT solar home picks one of two 20-year tariffs. New for 2026: a “Solar Energy Adjustment” charge (about 4¢/kWh produced) now applies to Netting customers, and which option wins depends on your usage, so run both numbers before you sign anything.
Verify at ct.gov (PURA) →Connecticut rebuilt its battery program on April 1, 2026: a smaller upfront rebate (highest in storm-prone “grid edge” neighborhoods) paired with much larger 10-year payments for letting the grid dispatch your battery. The program's own example puts total residential value around $18,000.
Verify at energystoragect.com →Applied right at the dealership when you buy or lease an eligible EV. Income-qualified buyers can stack Rebate+ for significantly more.
Verify at ct.gov (DEEP) →Residential solar equipment is exempt from Connecticut sales tax, and the added home value is exempt from property tax.
A direct grant toward your installation, with an extra $2,000 when you pair solar with a battery. Funding runs in rounds through Commerce RI, so timing matters.
Verify at commerceri.com →The alternative to a grant: sell your solar production to Rhode Island Energy at a locked-in rate. Small-scale enrollment (up to 25 kW) opens April 1 each year, first-come, and it fills fast. You can't combine REG with a REF grant, so it's one or the other.
Verify at energy.ri.gov →Rhode Island credits exported solar generously, and systems are sized to your usage, with credits allowed up to 125% of consumption.
Verify at energy.ri.gov →Rhode Island raised its EV rebates for purchases on or after January 5, 2026. The PowerUp RI charger rebate requires applying within 180 days of installation, so keep your electrician receipt.
Verify at drive.ri.gov →Solar equipment (and battery storage) is exempt from Rhode Island's 7% sales tax, and renewable systems are exempt from local property tax for 20 years.
New Hampshire's residential solar rebate is gone for good. The enabling law was repealed. If a website tells you it's still available, it's out of date.
Verify at energy.nh.gov →NH credits exported solar at full supply and transmission rates plus a portion of distribution. Systems up to 1 MW qualify. Legislation to add solar-charged batteries to net metering advanced in mid-2026, worth watching.
Verify at energy.nh.gov →Eversource NH has offered per-kWh battery rebates tied to demand-response participation, and the state's Renewable Energy Fund was redirected toward battery storage. Terms change, so check current offers before you buy.
Verify at nhsaves.com →NH towns can exempt solar's added value from property tax (RSA 72:61–64), and most do. File with your local assessor, and we can tell you if your town participates.
Vermont's statewide program covers systems up to 500 kW (permit required). Regulators approved a roughly 13% increase to the residential credit rate effective August 1, 2026, which is good news if you're planning now.
Verify at puc.vermont.gov →GMP installs and maintains two home batteries for $55/month (or $5,500 one-time, 10-year term), or pays a substantial upfront incentive when you enroll your own battery in its grid program (recently $850–$950 per kW, up to about $10,500). Enrollment caps were removed in 2025.
Verify at greenmountainpower.com →Vermont's state EV rebate fund ran dry in late 2024 and hasn't been refunded, but most Vermont utilities run their own EV and home-charger incentives (about 37 were listed statewide as of July 2026).
Verify at driveelectricvt.com →Vermont's solar sales tax exemption was scheduled to sunset June 30, 2026. Confirm its current status with the Vermont Department of Taxes before counting on it.
Verify at tax.vermont.gov →Maine's 2025 reform law (LD 1777) cut compensation for large community-solar projects but left residential rooftop net billing intact. Lawmakers authorized designing a successor program, so the rules may evolve, though existing customers have historically been grandfathered.
Verify at maine.gov →Among the biggest EV rebates in the country for income-qualified Mainers. Current amounts include a $1,000 bonus that expires September 30, 2026. Get income verification first, and pair the car with a $400 off-peak home charger rebate.
Verify at efficiencymaine.com →Qualifying home solar is exempt from Maine property tax, but it's not automatic. File the application with your town assessor by April 1 of the first year you claim it.
Verify at maine.gov →Efficiency Maine runs the state's flagship heat-pump and home-efficiency rebates, relevant if you're electrifying while you're at it, since panel capacity and wiring are where we come in.
Verify at efficiencymaine.com →The fine print (read it): This page is educational only, current as of July 2026. Heliotek doesn't administer these programs, can't guarantee you'll qualify, and doesn't provide tax advice. Amounts, funding, and rules change without notice, so always confirm with the program administrator, your utility, or your tax professional before making decisions.
Homeowners lost the 30% federal credit, but businesses kept more of theirs, with deadlines that reward acting early. Here's the commercial picture as of July 2026.
The 30% commercial credit still applies to solar projects that began construction by July 4, 2026; otherwise the system must be placed in service by December 31, 2027. Bonus adders survive: +10% for domestic content and +10% in designated energy communities. If a commercial solar project is on your radar, the calendar is the whole game.
The quiet winner of the 2025 law: standalone commercial battery storage keeps the full federal credit for projects starting construction through 2033 (phasing down after), and the 2027 solar deadline doesn't apply. New foreign-sourcing (FEOC) rules apply from 2026, so equipment origin matters; we design around it.
Commercial solar and storage qualify for 5-year accelerated depreciation, and the 2025 law permanently restored 100% bonus depreciation for property acquired after January 19, 2025. Combined with the ITC, a large share of project cost can come back in the first tax year, and your tax advisor can model it.
MA SMART pays commercial systems per-kWh rates for 20 years (set by size tier). CT's Energy Storage Solutions pays commercial batteries 10-year performance rates. RI's Renewable Energy Fund offers commercial grants from $0.70/watt (up to $400,000) plus storage adders. Ask us what applies to your building and state.
Timing is everything on the federal side. Eligibility rules (begin-construction tests, wage standards, sourcing) are technical. Confirm them with your tax advisor. We handle the other half: design, engineering, permits, and a code-compliant build by licensed electricians.
