Last updated: January 29, 2026

The federal 30% solar tax credit expired on December 31, 2025, eliminating what used to be the largest solar incentive available. But Massachusetts homeowners still have access to one of the strongest state-level incentive stacks in the nation. Between the 15% state tax credit, SMART 3.0 production payments, net metering credits, property tax exemptions, and sales tax savings, Massachusetts residents can still cut solar costs significantly.

Massachusetts Solar Incentives at a Glance

Massachusetts 15% State Solar Tax Credit

Maximum credit: $1,000
Filing form: Schedule EC
Refundable: No (but can carry forward 3 years)

Massachusetts offers one of the few state-level solar tax credits in thes nation. You can claim 15% of your total system cost, capped at $1,000, against your Massachusetts state income tax liability.

How It Works

The credit applies to the total installed cost of your system, including:

• Solar panels
• Inverters
• Racking and mounting equipment
• Battery storage (if installed with solar)
• Installation labor
• Permits and inspection fees

Example calculation:

• System cost: $21,700
• 15% of cost: $3,255
• Actual credit: $1,000 (capped)

Most residential systems hit the $1,000 cap. Any system costing $6,667 or more will max out the credit.

Advantages

Stacks with all other incentives. Unlike the expired federal credit, the Massachusetts credit doesn’t reduce the value of other programs. You can claim it alongside SMART payments, SRECs, net metering, and property tax exemptions.

No minimum system size. Even small 3 kW systems qualify for the full credit if they cost $6,667+.

Applies to primary or secondary residences. If you own a vacation home in Massachusetts, the system qualifies.

Eligibility Requirements

• System must be installed at your primary Massachusetts residence
• You must be the system owner (not a third party via lease/PPA)
• System must be new (not relocated from another property)
• You cannot be claimed as a dependent on another person’s tax return

How to Claim

1. Install and activate your system during the tax year you want to claim
2. File Massachusetts Schedule EC (Solar and Wind Energy Credit) with your Form 1 or Form 1-NR/PY
3. Attach documentation:
   • Installer’s certification
   • System specifications
   • Itemized invoice showing total cost
4. Apply credit to your state tax liability for that year

If you don’t have enough tax liability: The credit is non-refundable, meaning you can’t receive a payment if your credit exceeds your taxes owed. However, you can carry forward unused credit for up to 3 years.

Example scenario:

• System installed in 2026
• Total credit earned: $1,000
• 2026 state tax liability: $400
• Credit applied in 2026: $400
• Remaining credit carried to 2027: $600

Important: You can only claim the credit once per principal residence. If you’ve already claimed it for a previous system at the same home, you cannot claim it again for expansions or replacements.

SMART 3.0 Program: Earn $0.03/kWh for 10 Years

Program term: 10 years (residential ≤25 kW)
Payment structure: Fixed monthly incentive per kWh produced
Application opens: January 1 annually

The Solar Massachusetts Renewable Target (SMART) 3.0 program is Massachusetts’ flagship solar incentive. Unlike tax credits that reduce upfront costs, SMART provides ongoing cash payments based on how much electricity your system generates—regardless of whether you use it or send it to the grid.

How SMART 3.0 Works

You receive a fixed payment for every kilowatt-hour (kWh) your system produces, paid monthly or quarterly by your utility company for 10 years from the date your system goes live. The 20-year term applies only to commercial systems above 25 kW — residential homeowners are on the 10-year schedule.

SMART 3.0 is completely separate from net metering. You earn SMART payments for all production AND receive net metering credits for excess exports. These stack—you get both simultaneously.

Residential Incentive Rates (≤25 kW systems)

For residential systems 25 kW or smaller, SMART 3.0 uses a flat incentive rate set annually by the Massachusetts Department of Energy Resources (DOER).

Program Year 2026 residential flat rates:

• Base compensation: ~$0.03/kWh for 10 years
• Rates vary slightly by utility territory

These rates are significantly lower than the original SMART program’s $0.18–$0.28/kWh. The trade-off is predictability — your rate is locked in at qualification and guaranteed for the full 10-year term regardless of future program changes.

Example Income Calculation

System specs:

• Size: 7 kW
• Annual production: 8,400 kWh (based on 3.84 peak sun hours/day × 365 days × 7 kW × 0.77 derate factor)
• SMART rate: $0.03/kWh

Annual SMART income: 8,400 kWh × $0.03 = $252/year

10-year total: $252 × 10 = $2,520

While this is far lower than earlier SMART iterations, it still provides predictable, guaranteed income for a full decade — on top of your net metering savings, which continue for the life of the system.

Bonus Adders for Energy Storage

Systems paired with battery storage qualify for an additional adder. SMART 3.0 calculates storage adders using an Energy Storage Multiplier based on battery capacity and discharge duration.

Storage adder example:

• 10 kWh battery with 2+ hours of discharge duration
• Estimated storage adder: +$0.04/kWh
• This increases total compensation to approximately $0.07/kWh

A low-income household adding a battery could earn up to $0.10/kWh ($0.06 base + $0.04 storage adder). Battery systems also qualify for the 15% state tax credit (applied to the full solar + battery cost) and may be eligible for separate utility battery incentive programs.

Low-Income Adders

Low-income households (≤80% area median income) receive double the standard flat incentive rate, making solar significantly more accessible.

Low-income rate: ~$0.06/kWh (20-year term)

How the Flat Rate Is Calculated

For systems ≤25 kW, SMART 3.0 uses this formula:

Flat Incentive Rate = Base Compensation Rate – Value of Energy (VOE)

• Base Compensation Rate: Set annually by DOER based on system installation costs
• Value of Energy (VOE): The economic value of the electricity you generate, calculated from your 3-year average electricity cost

Because the VOE is subtracted, higher electricity rates actually reduce your SMART payment. This prevents “double compensation” since you’re already saving money on avoided utility charges through net metering.

Program Capacity and Enrollment

SMART 3.0 allocates 900 MW of capacity annually for systems subject to the capacity cap. However:

• Systems ≤25 kW are cap-exempt (unlimited enrollment)
• Behind-the-meter systems ≤250 kW are also cap-exempt

This means residential homeowners can enroll without worrying about capacity blocks filling up, unlike the original SMART program where late applicants received lower rates or were wait-listed.

How to Enroll in SMART 3.0

Step 1: Submit Statement of Qualification Capacity (SQC)
Your installer submits this application to your utility before installation. This locks in your SMART rate.

Step 2: Install your system
Complete installation, pass inspections, and receive interconnection approval.

Step 3: Submit Statement of Completion
Within 6 months of SQC approval, submit proof of completion:

• Final inspection approval
• Interconnection date
• System specifications
• Production meter information

Step 4: Receive monthly payments
Your utility begins monthly or quarterly SMART payments, typically via direct deposit or check.

Critical timing: Apply for SMART before installation. Waiting until after interconnection may result in delays or ineligibility.

SMART vs. SRECs

You might be wondering: what about SRECs (Solar Renewable Energy Certificates)?

The SREC program closed to new applications on November 26, 2018. New solar systems installed after this date cannot participate in the SREC market. Only systems that qualified before this deadline continue earning SRECs.

SMART 3.0 replaced the SREC program as Massachusetts’ primary solar production incentive. If your system was installed before November 2018 and qualified for SRECs, you can continue earning SREC income but cannot participate in SMART. If your system is new in 2026, you’re eligible for SMART only — $0.03/kWh for 10 years, with the rate locked in at the time of your application.

Net Metering: Full Retail Credit for Excess Solar

Credit value: ~90–100% of retail electricity rate
Rollover: Credits carry forward indefinitely
Eligibility: Automatic for systems ≤25 kW

Net metering is one of Massachusetts’ most valuable solar benefits. When your system produces more electricity than you use, the excess is sent to the grid and you receive credits on your utility bill worth nearly the full retail rate you’d normally pay.

How Net Metering Works

1. Your solar system generates electricity
2. You use what you need in real-time (this power is free)
3. Excess production flows to the grid
4. Your meter “spins backward” (metaphorically)
5. You receive bill credits for the exported kWh

Example:

• Your system produces 1,000 kWh in July
• Your home uses 600 kWh
• Excess sent to grid: 400 kWh
• Retail rate: $0.29/kWh
• Credit earned: 400 kWh × $0.29 = $116

This credit applies to future bills. If you generate more in summer than you use, those credits offset your higher winter consumption when solar production drops.

What Net Metering Credits Cover

Credits apply to most components of your electric bill:

• Supply charges (cost of electricity)
• Distribution charges (delivery fees)
• Transmission charges
• Basic service charges

Not covered: Fixed customer charges (~$5–15/month) that apply regardless of usage.

Your net metering credit value is typically 90–98% of the full retail rate because a few small non-bypassable charges are excluded. At $0.29/kWh retail, you’re credited about $0.26–$0.28/kWh for exports.

2025 Net Metering Expansion

In February 2025, Massachusetts raised the automatic net metering threshold from 10 kW to 25 kW. This means:

• Systems up to 25 kW AC automatically qualify for full retail-rate net metering
• No need to apply for limited “cap space”
• You can size your system for future needs (EV charging, heat pumps) without losing benefits

Systems between 26–60 kW may also qualify as cap-exempt if they serve on-site load and have an interconnection agreement dated January 1, 2021 or later.

Credit Rollover

Net metering credits never expire. They roll over month-to-month indefinitely.

Seasonal balancing example:

• Summer months: Generate 1,200 kWh, use 700 kWh → Bank 500 kWh credit
• Winter months: Generate 400 kWh, use 900 kWh → Use 500 kWh from summer credits

At the end of your 12-month billing cycle, any remaining excess credits are typically paid out at a lower “avoided cost” rate (around $0.03–$0.05/kWh), which is far less valuable than the retail credit. This is why proper system sizing matters—you want to generate close to your annual usage, not vastly exceed it.

Net Metering + SMART = Maximum Value

You earn SMART payments for ALL production, whether you use it or export it.
You earn net metering credits only for excess exports.

Example monthly scenario:

• Production: 800 kWh
• Consumption: 600 kWh
• Excess export: 200 kWh

SMART income: 800 kWh × $0.03 = $24
Net metering credit: 200 kWh × $0.27 = $54
Avoided utility charges: 600 kWh × $0.29 = $174
Total monthly value: $252

This is why Massachusetts solar works even without abundant sunshine—you’re compensated through multiple stacking programs.

Potential Policy Risk (2026 Update)

In January 2026, the Massachusetts Department of Public Utilities (DPU) opened docket D.P.U. 25-200, investigating “reductions to the value of the net metering credit.”

This means net metering rates could be cut in the future, similar to what happened in California (75% reduction) and Illinois (50% reduction). If you’re considering solar, interconnect before any policy changes take effect to grandfather your system into current net metering rates for 25 years.

Property Tax Exemption: Save $500+/Year for 20 Years

Exemption period: 20 years
Automatic: No application required
Estimated savings: $300–$500 annually

Massachusetts provides a 100% property tax exemption on the added home value from solar installations for 20 years. This is one of the longest property tax exemptions in the nation.

How It Works

Solar systems typically add $15,000–$20,000 to your home’s assessed value. Without the exemption, this would increase your annual property taxes.

Example:

• Home value before solar: $400,000
• Solar system adds: $15,000
• New home value: $415,000
• Massachusetts average property tax rate: 1.12%

Without exemption:
Annual property tax increase = $15,000 × 1.12% = $168/year

With exemption:
Annual property tax increase = $0

Over 20 years, this saves $3,360 (and potentially more if your local rate exceeds the state average).

Eligibility

• System must be solar PV or solar thermal
• Must be used for heating, cooling, or electricity generation
• Applies to systems ≤25 kW for residential properties (larger systems may require a Payment in Lieu of Taxes agreement with the municipality)
• Must be owned by the property owner (leased systems may not qualify)

Application Process

None. The exemption is automatic. When your municipality assesses property values annually, the solar system’s added value is excluded from the taxable assessment for 20 years from installation.

Verification: If you want to confirm the exemption is being applied, contact your local tax assessor’s office with proof of installation date.

What Happens After 20 Years?

After the 20-year exemption expires, the solar system’s value may be added to your property tax assessment. However:

• The system will be 20 years old and significantly depreciated
• Many systems are replaced or upgraded by this point
• The added value will be minimal

Sales Tax Exemption: Save $1,300+ Upfront

Exemption amount: 6.25% of total system cost
Applied automatically at purchase
No application required

Solar equipment and installation labor are 100% exempt from Massachusetts’ 6.25% sales tax. This saves you over $1,300 upfront on a typical system.

What’s Covered

The exemption applies to:

• Solar panels (modules)
• Inverters (string, micro, or hybrid)
• Battery storage systems
• Mounting and racking hardware
• Wiring and electrical components
• Installation labor
• Permits and inspection fees

Example savings:

• System cost: $21,700
• Sales tax rate: 6.25%
• Sales tax exemption: $1,356

How It Works

The exemption is applied automatically at the point of sale. Your installer purchases equipment in bulk and does not charge you sales tax on the final invoice.

Verification: Review your contract and final invoice to confirm sales tax is $0 or marked as “exempt.”

Eligibility

• System must be solar PV, solar thermal, or wind energy
• Must be installed on residential or commercial property in Massachusetts
• Applies to new equipment only (not used/refurbished systems)

There is no application process. If your installer incorrectly charges sales tax, request a refund directly from them—not from the Massachusetts DOR.

Total Financial Breakdown: What You Actually Pay in 2026

Let’s calculate the real cost and return for a typical Massachusetts solar installation in 2026.

Example System Specifications

• System size: 7 kW
• Annual production: 8,400 kWh (3.84 peak sun hours/day average)
• Total cost before incentives: $21,700 ($3.10/watt average MA pricing)
• Location: Boston area (Eversource territory)
• Electricity rate: $0.29/kWh

Upfront Cost Breakdown

First-Year Tax Credits

Net cost after year 1 tax credits: $20,344 – $1,000 = $19,344

Annual Savings & Income

Net Metering Seasonal Balancing

In Massachusetts, solar production varies significantly by season:

• Summer (May–Aug): ~1,000 kWh/month production
• Winter (Nov–Feb): ~400 kWh/month production

Net metering allows you to bank summer credits and use them in winter, effectively “flattening” your costs across the year.

Payback Analysis

Total system cost (after tax credits): $19,344 Annual savings + income (years 1–10): $2,988 Simple payback period: 19,344 ÷ 2,988 = 6.5 years

How savings break down across 25 years:

• Years 1–10: $2,988/year (utility savings + SMART + property tax exemption) = $29,880
• Years 11–20: $2,736/year (utility savings + property tax exemption, SMART complete) = $27,360
• Years 21–25: $2,436/year (utility savings only) = $12,180

Total 25-year gross value: $69,420

Less initial cost: −$19,344

Net 25-year profit: ~$50,000

Key Assumptions

• Electricity rates remain flat (conservative—rates have increased 32% over the past decade)
• No battery storage included (adding storage increases upfront cost but adds resilience and potential incentives)
• System degradation: ~0.5%/year (most panels are warrantied to 85% production at year 25)
• No major repairs needed (panels are warrantied for 25 years, inverters typically 10-12 years)
• If electricity rates increase 3% annually (historically conservative), your 25-year net profit increases to over $65,000.

Additional Local Incentives & Utility Programs

Municipal Utility Rebates

Some Massachusetts municipal light plants (MLPs) offer additional solar rebates. These vary widely by town and change annually.

Examples of MLP rebates (subject to change):

• Wakefield Municipal Gas & Light: $1.20/watt (up to $7,800 for a 6.5 kW system)
• Concord Municipal Light Plant: $650/kW (up to $3,125 total)
• Reading Municipal Light Department: $0.75/watt
• Braintree Electric Light Department: $1,000 for systems 5-10 kW

Important: Municipal rebates reduce your system’s net cost, which in turn reduces your state tax credit since it’s calculated on net expenditure.

How rebates affect credits:

• System cost: $20,000
• Municipal rebate: $5,000
• Net cost: $15,000
• State credit: 15% × $15,000 = $1,000 (still capped at $1,000)

Contact your local municipal utility to confirm current programs.

Battery Storage Incentives

Massachusetts offers several battery-specific programs:

ConnectedSolutions (Eversource, National Grid, Cape Light Compact):

• Incentive: ~$300–$500/kW annually for allowing utility to discharge your battery during peak demand events (typically 50-60 hours/year in summer)
• Eligibility: Battery must be enrolled in the ConnectedSolutions program
• Compatible batteries: Tesla Powerwall, LG Chem, Enphase, Generac, and others

Example: A 13 kWh Tesla Powerwall 3 could earn $300–$400/year through ConnectedSolutions for 5-10 years.

Unitil Battery Program:

• Incentive: $100/kWh rebate (one-time)
• Example: 15 kWh battery = $1,500 rebate
• Eligible brands: Duracell, Emporia, Tesla (as of 2026)

National Grid Battery Rebate:

• Incentive: $2,000 for batteries 5-20 kWh
• Requirement: Battery must be enrolled in Connected Homes Program

Batteries also qualify for the 15% state tax credit when installed with solar.

Community Solar

If you rent or have a roof unsuitable for solar, community solar allows you to subscribe to a solar farm and receive net metering credits on your bill.

SMART 3.0 community solar requirements:

• Minimum 40% low-income subscribers (or 100% for certain project types)
• Minimum bill savings: 10% for market-rate customers, 20% for low-income customers

Community solar subscriptions typically save 10-20% on your electric bill without any upfront cost or installation.

How to Claim Massachusetts Solar Incentives (Step-by-Step)

Step 1: Get Multiple Quotes (2-3 Months Before Installation)

• Obtain 3+ quotes from Massachusetts-licensed solar installers
• Verify installer is MassCEC-approved for SMART enrollment
• Confirm pricing includes all eligible equipment (panels, inverters, racking, labor)
• Ask about current SMART 3.0 rates and timeline for interconnection

Step 2: Apply for SMART Program (Before Installation)

• Your installer submits Statement of Qualification Capacity (SQC) to your utility
• Receive capacity allocation confirmation and locked-in SMART rate
• Critical: Apply before installation to lock in Program Year 2026 rates

Step 3: Finalize Financing

Decide how you’ll pay:

• Cash purchase: Best long-term ROI, immediate ownership
• Solar loan: $0 down options available, spreads cost over 10-25 years
• Home equity loan/HELOC: Often lower interest than solar-specific loans
• Lease/PPA: Not recommended—you forfeit the state tax credit and SMART payments

Step 4: Install System & Pass Inspection

• Licensed installer completes installation (typically 1-3 days)
• Local building inspector approves electrical work
• Utility performs interconnection inspection
• System is activated and begins producing electricity

Step 5: Apply for Net Metering (Installer Handles)

Your installer submits the net metering application to your utility along with the interconnection agreement. Approval is typically automatic for systems ≤25 kW.

Step 6: Submit SMART Statement of Completion

Within 6 months of SQC approval:

• Submit final inspection approval
• Provide interconnection date and system specifications
• Utility begins monthly/quarterly SMART payments (typically via direct deposit)

Step 7: File Tax Credit (Year 1 Tax Filing)

When filing your 2026 Massachusetts state taxes (April 2027):

• Complete Massachusetts Schedule EC (Solar and Wind Energy Credit)
• Attach installer’s certification and system documentation
• File with Form 1 or Form 1-NR/PY
• Claim up to $1,000 credit against 2026 state income tax liability

Documents needed:

• Itemized invoice showing total system cost
• Installer’s certification
• Proof of installation date (interconnection approval or final inspection)

Step 8: Verify Sales Tax Exemption (Automatic)

Confirm your final invoice shows $0 sales tax or “exempt.” If sales tax was incorrectly charged, contact your installer for a refund.

Step 9: Verify Property Tax Exemption (Automatic)

No action required. The exemption is applied automatically when your municipality assesses property values. To verify, contact your local tax assessor’s office after your first post-installation assessment.

No Federal Credit? No Problem

Fun fact. Massachusetts ranks #1 in solar policy despite ranking #39 in sunshine hours nationwide. The state receives an average of just 3.84 peak sun hours per day, about 40% less than Arizona, yet solar remains financially compelling here because of strong state programs and the highest electricity rates in the continental U.S.

Average Massachusetts residential electricity rate: $0.29/kWh (well above the national average of approximately $0.17/kWh)

With rates this high, every kilowatt-hour your solar system generates saves real money, and Massachusetts ensures you’re compensated fairly through full retail-rate net metering. The state’s SMART 3.0 program provides guaranteed payments for 10 years, while the SREC market—though closed to new entrants—still benefits existing systems with ongoing income.

Even without the federal credit, a typical 7 kW system in Massachusetts costs around $21,700 upfront but delivers approximately $50,000 in net profit over 25 years through reduced bills, production incentives, and tax exemptions — with more upside if electricity rates continue rising.

Frequently Asked Questions

Q: Are Massachusetts solar incentives worth it without the federal tax credit?

A: Yes. Massachusetts ranks #1 in solar policy despite limited sunshine because state-level incentives, high electricity rates, and excellent net metering policies make solar financially viable. A typical 7 kW system costs ~$19,300 after the state tax credit and generates approximately $50,000 in net profit over 25 years through utility savings, SMART payments, and property tax exemptions. With electricity rates at $0.29/kWh — well above the national average — payback periods are still 6–7 years even without federal support.

Q: Can I claim the Massachusetts state tax credit if I don’t owe enough state taxes?

A: The $1,000 state credit is non-refundable, meaning you can’t receive cash back if it exceeds your tax liability. However, you can carry forward unused credit for up to 3 years. Example: If you owe $400 in state taxes in 2026, you apply $400 of the credit and carry forward the remaining $600 to your 2027 return.

Q: What’s the difference between SMART and SRECs?

A: The SREC program closed to new applicants on November 26, 2018. SMART 3.0 replaced it as Massachusetts’ primary production incentive. Systems installed before November 2018 can continue earning SRECs (~$350/SREC, or ~$2,900/year for a 7 kW system) for 10 years, but cannot participate in SMART. New systems in 2026 are eligible only for SMART 3.0, which pays a flat rate of ~$0.03/kWh for 10 years (~$252/year for a 7 kW system, or $2,520 over the full term). The rate is lower than historic SREC values, but it’s locked in at qualification and guaranteed — no market volatility.

Q: How long does the Massachusetts property tax exemption last?

A: The property tax exemption lasts 20 years from installation date. Solar systems exempt the added home value (~$15,000) from property tax assessment, saving ~$300/year. Over 20 years, this totals $6,000 in savings. The exemption is automatic—no application required. After 20 years, the system’s value may be added to your assessment, but the system will be significantly depreciated by then.

Q: Do I pay sales tax on solar in Massachusetts?

A: No. Solar equipment and installation are 100% exempt from Massachusetts’s 6.25% sales tax. This saves ~$1,350 upfront on a $21,700 system. The exemption is applied automatically at point of sale—you don’t need to claim a refund.

Q: How does net metering work in Massachusetts?

A: When your solar system produces more electricity than you use, the excess is sent to the grid and you receive credits on your utility bill at ~90-98% of the full retail rate (~$0.26-$0.28/kWh). Credits roll over month-to-month indefinitely, allowing you to bank summer production and use it in winter. Net metering is separate from SMART—you receive both SMART payments for all production AND net metering credits for excess exports.

Note: The Massachusetts DPU opened docket 25-200 in January 2026 reviewing potential changes to net metering rates — systems interconnected before any policy change are expected to be grandfathered for 25 years.

Q: What happens to SMART payments if I move?

A: SMART payments stay with the physical address and system, not the homeowner. If you sell your home, the new owner receives the remaining SMART payments for the balance of the 20-year term. This makes solar a strong selling feature—buyers inherit guaranteed income. The same applies to the property tax exemption and any remaining SREC eligibility (for pre-2018 systems).

Q: Can renters benefit from Massachusetts solar incentives?

A: Renters cannot install solar on properties they don’t own, but they can participate in community solar programs. Massachusetts requires community solar projects to enroll at least 40% low-income subscribers, with guaranteed minimum savings of 10% (market-rate) or 20% (low-income). You receive net metering credits on your utility bill without any upfront cost or installation. Contact Eversource, National Grid, or your local utility for available community solar subscriptions.

Q: Are solar batteries eligible for Massachusetts incentives?

A: Yes. Solar batteries qualify for the 15% state tax credit (up to $1,000 on the combined solar + battery cost). Batteries may also receive a SMART 3.0 storage adder (+$0.01-$0.02/kWh) depending on capacity and discharge duration. Additionally, utilities offer battery-specific incentives like ConnectedSolutions ($300-$500/year for 5-10 years) and one-time rebates ($1,500-$2,000 depending on utility). However, batteries do not generate net metering credits—only solar production does.

Q: What’s the solar payback period in Massachusetts without the federal credit?

A: Most systems pay for themselves in 6-7 years. With the state tax credit, sales tax exemption, SMART income, net metering savings, and property tax exemptions, a typical $21,700 system costs ~$19,300 net upfront and generates ~$2,988/year in value, resulting in a 6.5-year payback. After payback, the system continues generating $50,000+ in profit over its remaining 18+ years.

Q: Do I need a south-facing roof for solar in Massachusetts?

A: South-facing is ideal but not required. East- and west-facing roofs produce ~85-90% as much energy as south-facing. Even north-facing roofs with low angles can work. Ground-mounted systems are an alternative if roof orientation is poor. Your installer will model your specific roof’s production potential using satellite data and solar design software to determine if your property is suitable.

Q: Will net metering change in Massachusetts?

A: Possibly. In January 2026, the Massachusetts DPU opened docket 25-200 investigating “reductions to the value of the net metering credit.” This means rates could be cut in the future, similar to California (75% reduction) and Illinois (50% reduction). However, systems interconnected before policy changes take effect are typically grandfathered for 25 years. If you’re considering solar, act now to lock in current net metering rates before they potentially change.

Next Steps: How to Start Your Massachusetts Solar Journey

Massachusetts proves solar works everywhere—policy matters more than sunshine. Even without the federal tax credit, the average Massachusetts homeowner pays ~$19,300 net after incentives for a system that generates over $50,000 in profit over 25 years.
