Solar Energy for Rental Properties and Landlords 2026

Solar panels on a primary home are straightforward: the homeowner installs the system, claims the 30% Section 25D federal tax credit, and saves money on utility bills. But if you own rental property — a single-family rental, a duplex, a triplex, or a quadplex — the rules, the economics, and the tax treatment are entirely different. Done right, rental property solar can produce returns well above the residential numbers. Done wrong, you can lose thousands in missed tax benefits.

This guide covers everything residential landlords need to know: which tax credit applies, how depreciation supercharges returns, how to structure tenant agreements, which financing options work for rentals, and how to evaluate whether solar makes sense for your specific property.

The Most Important Distinction: Section 25D vs. Section 48

The federal solar tax credit exists in two forms, and which one applies to your rental property determines whether you get 30% — or dramatically more.

Section 25D — the residential solar credit most homeowners use — does not apply to rental properties. Section 25D requires the property to be your principal residence or second home. A rental property where tenants live is neither. If you claim Section 25D on a rental property, you're taking a credit you're not entitled to.

Section 48 — the commercial clean energy credit — applies to rental properties. Any income-producing property, including a single-family rental, qualifies for Section 48. The base credit rate is 30%, matching Section 25D's rate. But unlike Section 25D, Section 48 stacks with other tax benefits:

• 30% ITC (or 40% in Energy Community zones)
• MACRS 5-year bonus depreciation: In 2026, 40% first-year bonus depreciation applies to commercial solar property (the bonus percentage steps down each year under TCJA)
• Low-Income Communities bonus: An additional 10–20% ITC if the property is in a low-income census tract or affordable housing program (up to 50% total ITC)

Year-One Tax Recovery Example

A landlord installs a 6 kW system on a single-family rental in Austin, Texas. Installed cost: $18,000.

Benefit	Amount
30% Section 48 ITC	−$5,400
Year-1 40% MACRS bonus depreciation	−$5,040
Total year-1 cost recovery	−$10,440
Net after-tax cost in Year 1	$7,560

Compare this to a primary-residence owner using Section 25D: they get only the $5,400 ITC, with no depreciation, for a net cost of $12,600. The rental property owner recovers 58% of system cost in year one — vs. 30% for the homeowner.

Important caveat: You must have enough passive income or active income from the rental to absorb these benefits. Consult a CPA to verify your specific passive activity loss position before assuming full first-year benefit realization.

The Depreciation Stack in Detail

Under the Modified Accelerated Cost Recovery System (MACRS), solar equipment installed on commercial property depreciates on a 5-year schedule. In 2026, the bonus depreciation rate is 40% (down from 60% in 2024, stepping to 20% in 2027, then 0% in 2028 under current law unless Congress extends it).

For a $18,000 system:

• Year 1 bonus depreciation: 40% × $18,000 × 0.5 (mid-year convention) = $3,600 additional depreciation
• Regular 5-year MACRS in Year 1: 20% × $18,000 = $3,600 (offset somewhat by bonus)
• Total 5-year accumulated depreciation: Full system cost (the ITC does not reduce the depreciable basis under current IRA rules — confirm with your CPA)

For a landlord in the 22% federal tax bracket, the $7,200 in Year 1 depreciation generates $1,584 in tax savings on top of the $5,400 ITC.

Caution — passive activity loss rules: Depreciation and the ITC on rental property are typically passive tax benefits. Landlords with adjusted gross income above $100,000 (phasing out at $150,000) face limitations on how much passive loss they can use in any given year. A real estate professional (spending 750+ hours/year in real estate activities) can classify rental income as active income and absorb unlimited depreciation and credits.

Property Types: Which Rental Properties Work Best for Solar?

Single-Family Rentals

The cleanest scenario. One system, one meter, one tenant. The landlord owns the system and the house; the tenant has no ownership interest in the solar equipment.

Utility bill structure: You have two options:

1. Tenant pays utility directly: The tenant gets the full electricity savings. Solar increases property attractiveness and may support higher rent but doesn't directly reduce your expenses.
2. Landlord pays utilities, passes through to tenant as part of rent: Solar directly reduces the utility cost you carry, improving your net operating income.

Most single-family rentals operate with tenant-paid utilities. In that model, solar primarily supports rent premium and tenant retention rather than direct expense reduction.

Rent premium: LBNL research shows solar-equipped homes rent faster and at premiums of 3–5% in most markets. At $2,000/month rent, a 4% premium = $80/month or $960/year additional income — on top of the ITC and depreciation tax benefits.

Duplex (2-Unit)

With two units, the system design gets more nuanced. You have several options:

• One system on common roof, feeds shared systems only (exterior lighting, common-area HVAC, shared water heater): Clean Section 48 eligibility, no tenant billing complexity
• One system split to serve both units' meters: Requires a virtual net metering arrangement or energy allocation system. Not all utilities accommodate this for 2-unit properties.
• Virtual Net Metering (VNM): In states with VNM (CA, NY, MA, NJ, IL, CO, MD, CT, MN, OR), you can allocate credits from a single system to multiple separately-metered tenants. See the Multifamily Solar Guide for VNM state details.

Triplex and Quadplex (3–4 Units)

At 3–4 units, the Section 48 ITC still applies (these are residential rental properties, not commercial buildings requiring different treatment). The design complexity increases, but so does the ITC opportunity: a 4-unit building with a larger shared system qualifies for the 30% ITC (or 40% in Energy Community zones) on a proportionally larger system.

Low-Income Housing Bonus Credit: If any unit is income-restricted under LIHTC (Low Income Housing Tax Credit) or qualified affordable housing programs, the Section 48 LIC bonus credit (+10%) and affordable housing adder (+20%) may stack to produce 40–50% total ITC. This transforms the economics dramatically.

Limits: 5+ Units

Once your building reaches 5+ units, it crosses into commercial/multifamily territory where different tax structures (C-PACE financing, tax credit syndication, opportunity zone programs) become relevant. See the Multifamily Buildings Guide for those scenarios.

The Split Incentive Problem — and How to Solve It

The fundamental challenge with rental property solar is the split incentive: you (the landlord) pay for the system; your tenant benefits from lower electricity bills (if utilities are tenant-paid). This creates a classic public goods problem — you bear the cost, they get the reward.

Solution 1: Green Lease Provisions

A green lease includes clauses that align landlord and tenant incentives around energy efficiency and solar. Key provisions:

Solar pass-through clause: If the landlord pays utilities and solar reduces the utility cost, the lease specifies how savings are shared or whether the tenant pays a portion of the system cost as part of rent.

Solar equipment access clause: Tenant agrees to grant access to roof for solar installation, maintenance, and inspection. Required in most jurisdictions to prevent lease-breaking disputes when you add solar.

Utility rate transparency clause: If you're moving from a tenant-paid utility model to a landlord-paid-with-solar-pass-through model, specify how the "solar rate" will be calculated and billed.

No-modification clause: Tenant agrees not to install shading structures, satellite dishes, or other equipment that could reduce solar production without landlord approval.

Solution 2: Utility Submetering

In states that allow it, you can install a submeter to track the solar generation attributed to each unit. Tenants get credit for their allocated solar generation, reducing their utility bills. You recapture some of the solar benefit through higher rent or reduced turnover.

Solution 3: Solar-Included Rent

Simplest structure: install solar, increase monthly rent by the value of the solar benefit ($50–$150/month depending on system size and market). Tenants effectively pay for the solar through rent; you capture the full ITC, depreciation, and rent premium. Requires careful market analysis to ensure the premium is supportable.

Solution 4: Tenant-Financed Solar

Some states allow landlords to offer tenants the option to finance the solar system themselves (through an on-bill arrangement or a landlord-facilitated loan). The tenant owns or partially finances the system, gets the tax credit if they have sufficient tax liability, and the landlord gets improved tenant retention. Uncommon but available in select markets.

Financing Rental Property Solar

The financing options for rental properties differ significantly from primary residence solar.

PACE Financing (Property Assessed Clean Energy)

PACE is the most widely used financing mechanism for commercial/rental solar. A lien is recorded against the property (classified as a property tax assessment) and repaid through property tax bills over 5–25 years.

Pros: No personal credit requirements; long terms (up to 25 years); non-recourse structure; transferable at sale (new owner inherits the obligation via property tax assessment).

Cons: The PACE lien takes priority over the first mortgage. If you have a mortgage on the rental property and your lender hasn't consented to PACE (many haven't explicitly), you may be in technical default. Fannie Mae and Freddie Mac don't allow PACE on conforming loans they hold. Before using PACE on a mortgaged rental property, get written lender approval.

PACE availability: 37 states have commercial PACE programs. California (CALFP), Florida (Ygrene, PACE Funding), Texas (SAVES), Colorado (RENU), New York (NY Green Bank PACE pilot), and most other large markets are covered.

Commercial Solar Loan

Unlike residential solar loans (which are typically unsecured personal loans), commercial solar loans for rental properties are:

• Secured by the property or equipment: Lower interest rates (typically prime + 1–3%)
• Can be structured as a business loan: Tax-deductible interest as a rental expense
• Longer terms available: 7–20 years for commercial loans vs. 5–20 years for residential
• SBA 504: For eligible small business owners who use the rental property as part of a business, SBA 504 loans can finance solar at below-market commercial rates (currently ~6–7%)

Home Equity Line of Credit (HELOC) / Cash-Out Refinance

If you have significant equity in the rental property, a HELOC or cash-out refinance at primary-residence rates is often the cheapest capital source. Interest is deductible as a rental expense (Schedule E).

Caution: If your rental property is held in an LLC (which many landlords do for liability protection), your personal HELOC cannot be secured by the LLC-owned property without triggering complex cross-entity issues. Work with a real estate attorney.

Direct Installment/Operating Lease

Solar companies will sometimes offer operating leases on rental properties. From a tax perspective, operating lease payments are deductible as a rental expense — but you don't get the ITC (the leasing company does). For landlords with insufficient tax liability to use the ITC, an operating lease may still produce positive cash flow without the tax credit complexity.

State-Specific Considerations for Rental Landlords

California

California's net metering situation for rental properties has two distinct paths:

• NEM 2.0-grandfathered properties (systems installed before April 14, 2023): export credits at retail rate (~$0.18–$0.32/kWh). These are the most valuable solar assets in California — if you're buying a rental property with an existing NEM 2.0 system, that grandfathering transfers to you. See the California Solar Guide.
• New NEM 3.0 systems: Export credits at ~$0.03–$0.05/kWh. Self-consumption is essential. For rental properties where tenants pay utilities (and thus use the solar electricity during the day), NEM 3.0 works better than for unoccupied properties or properties where tenants are absent during peak generation hours.

SGIP battery rebate: Available for rental properties in specific equity and equity resiliency tiers. $850–$1,000+/kWh for income-restricted properties.

Title 24 mandate: Rental properties built after 2020 in California must have solar on new construction.

Texas

Texas has no statewide net metering mandate. Rental property solar economics depend entirely on which utility territory you're in:

• Austin Energy: PVFIT buyback at $0.099/kWh — the best export rate in Texas. Single-family rentals in Austin Energy territory can export at nearly retail rates.
• CPS Energy (San Antonio): Value of Solar tariff at $0.029/kWh — very low export rate; design for self-consumption.
• Oncor, AEP, Reliant deregulated territories: REP (retail electric provider) determines export rate; highly variable by contract.

Texas's 100% property tax exemption for commercial and residential solar applies to rental properties (there is no primary-residence restriction in the Texas exemption). This is worth $8,000–$12,000+ in lifetime tax savings on a typical rental system. See the Texas Solar Guide.

Massachusetts

Massachusetts's SMART program (Solar Massachusetts Renewable Target) applies to rental properties and produces a 10-year PBI (production-based incentive) at $0.10–$0.22/kWh on total system production — not just what the tenant uses. This is particularly valuable for rental properties because the incentive income accrues to the system owner (you, the landlord) regardless of the tenant's energy usage.

A 6 kW rental property system in Eversource territory earning $0.15/kWh SMART income generates ~$1,080/year for 10 years ($10,800 total) on top of the ITC, depreciation, and any rent premium. Massachusetts sales tax exemption and property tax exemption also apply to rental properties. See the Massachusetts Solar Guide.

New Jersey

New Jersey's SREC II program generates SRECs (Solar Renewable Energy Credits) at $185–$270/MWh for 15 years. A 6 kW rental system generating 7,200 kWh/year earns ~7.2 SRECs/year at current prices, worth $1,330–$1,944/year. Rental property SREC income is taxable as business income and reported on Schedule E.

New Jersey's property tax exemption and sales tax exemption both apply to rental properties without primary-residence restrictions. See the New Jersey Solar Guide.

Illinois

Illinois Shines' 15-year REC contract applies to rental properties. At current block pricing (~$65–$80/REC), a 6 kW system generating 7,000 kWh/year earns ~$455–$560/year for 15 years ($6,825–$8,400 total). The ComEd sales tax exemption applies to both owner-occupied and rental installations. See the Illinois Solar Guide.

Maryland

Maryland's SREC market ($60–$90/MWh) and 30% state income tax credit for battery storage (up to $5,000) both apply to rental properties. The 100% property tax exemption and full 6% sales tax exemption are statewide, applying to all solar installations regardless of use. See the Maryland Solar Guide.

Tax Reporting for Rental Property Solar

Schedule E, Not Schedule A

All rental property solar income, expenses, and depreciation are reported on Schedule E (Supplemental Income and Loss), not Schedule A. This is true for:

• Electricity savings attributed to the rental property
• SREC/PBI income generated by the rental system
• Section 48 ITC (claimed on Form 3468, not Form 5695)
• MACRS depreciation deductions

Form 3468 — Investment Credit: This is the commercial ITC form. Unlike residential solar buyers who use Form 5695, rental property landlords use Form 3468 to claim the Section 48 ITC. The credit flows to Form 1120S (for S-corps), Form 1065 (for partnerships/LLCs), or Form 1040 Schedule E depending on your ownership structure.

ITC Recapture Risk

Unlike Section 25D (which has no recapture), Section 48 has a 5-year recapture schedule:

• Sell within Year 1: 100% recapture
• Sell in Year 2: 80% recapture
• Sell in Year 3: 60% recapture
• Sell in Year 4: 40% recapture
• Sell in Year 5: 20% recapture
• Sell in Year 6+: No recapture

If you sell the rental property within 5 years of claiming the Section 48 ITC, you must add back a portion of the credit. This affects the financial analysis of a rental property solar investment that you might sell in the near term.

1031 Exchange: If you sell the rental property through a 1031 exchange (deferring capital gains by reinvesting in another property), the ITC recapture is also deferred as long as the replacement property meets the exchange requirements. Work with a 1031-experienced CPA or attorney.

SREC/PBI Income Tax Treatment

SREC income and PBI income from rental property solar are ordinary income, taxable at your marginal rate. However, they are offset by the depreciation deduction and business expenses related to the rental property. A landlord generating $2,000/year in SREC income while also depreciating a $18,000 solar system may net zero additional taxable income for the first several years.

Financial Analysis: Is Rental Property Solar Worth It?

Let's run through a complete scenario for a typical single-family rental:

Property: 3-bedroom single-family rental, Raleigh, NC. Tenant pays utilities. System: 6 kW system, installed cost $18,600. Incentives: 30% Section 48 ITC = $5,580. No NC-specific state credit or property tax exemption (NC has no property tax exemption or sales tax exemption for solar). Depreciation: 40% bonus in Year 1 × $18,600 × 0.5 mid-year convention = $3,720 additional depreciation. 22% bracket: $3,720 × 0.22 = $818 tax savings. Rent premium: $60/month × 12 = $720/year additional rent. System production: 8,400 kWh/year (NC 4.5 PSH/day). Tenant uses most of it during the day (home during work hours = 55% self-consumption assumed).

Year	Benefit	Amount
Year 1	Section 48 ITC	$5,580
Year 1	MACRS bonus depreciation tax savings	$818
Year 1–25	Rent premium ($720/yr)	$18,000
Year 1–25	Tenant electric cost savings (indirect)	—
Total	25-year net benefit	$24,398
Net cost	($18,600 − $5,580 − $818)	$12,202
Net gain	$24,398 − $12,202	$12,196
Simple payback	$12,202 / ($720 rent)	~17 years

This is modest for a rental property with tenant-paid utilities. But add North Carolina's Energy Community 40% ITC (Western NC coal counties: applies to many NC Energy Community census tracts) and the ITC jumps to $7,440, improving payback to ~12 years. Add a Massachusetts SMART incentive scenario and payback drops to under 7 years.

The highest-return rental solar markets are states where the landlord directly benefits from electricity savings (landlord pays utilities), SREC or PBI income accrues to the system owner, and state tax exemptions eliminate sales and property tax friction: Massachusetts, New Jersey, Maryland, Connecticut, Illinois, and Rhode Island consistently produce the fastest payback for rental solar.

5 Common Landlord Solar Mistakes

1. Claiming Section 25D instead of Section 48: Results in an incorrect credit claim, potential IRS audit, and repayment with penalties and interest. Always use Form 3468 for rental property.

2. Using PACE without mortgage lender consent: Most PACE programs require notification of the mortgage lender. Proceeding without consent can trigger a default clause in your mortgage.

3. No solar provision in the lease: Without explicit solar access, maintenance, and modification clauses, a tenant can legally interfere with maintenance access, claim the solar equipment as part of the property, or create disputes at lease renewal.

4. Ignoring the Section 48 recapture risk when flipping: Landlords who buy, install solar, and sell within 5 years face ITC recapture. Model the exit strategy before committing to the investment.

5. Not accounting for passive activity loss limits: If your AGI is above $100,000 and you're not a real estate professional, passive loss limitations may prevent you from using the full depreciation benefit in Year 1. The unused losses carry forward, but the timing affects your cash flow model.

FAQ

Can I claim the 30% solar tax credit on a rental property? Yes — but you must use the Section 48 commercial tax credit (Form 3468), not the Section 25D residential credit (Form 5695). Section 25D is for your primary or second home only. Section 48 applies to any income-producing property and stacks with MACRS depreciation.

Does solar increase my rental property's value? LBNL research shows owned solar systems add $3,000–$5,000/kW to residential property values. For a 6 kW rental property system, expect $18,000–$30,000 in added value (before depreciation recapture considerations). Leased systems do not add appraised value.

Who gets the electricity savings — the tenant or the landlord? In the most common structure (tenant pays utilities), the tenant benefits from lower electricity bills. The landlord benefits indirectly through potential rent premium and improved tenant retention. If the landlord pays utilities, the landlord directly captures the savings.

Can I use PACE financing for my rental property? Yes — commercial PACE is designed for rental and investment properties. However, you must notify your mortgage lender; some lenders will object to the priority lien. PACE is generally not available for 5+ unit properties through commercial programs.

Does the Energy Community 40% ITC bonus apply to rental properties? Yes — the 40% Energy Community bonus (for properties in qualifying coal community, oil & gas, or brownfield census tracts) applies to Section 48 commercial solar, which includes rental properties. Check your property address at the IRS Energy Community mapper to verify eligibility.

Putting It All Together: Rental Property Solar Decision Framework

Solar makes the most sense for rental properties when:

✅ You have sufficient tax liability to use the Section 48 ITC and depreciation in Year 1 (or are a real estate professional with active income classification)

✅ You're in a state with strong above-ITC incentives (Massachusetts SMART, New Jersey SREC II, Maryland SREC/state credit, Illinois Shines, Connecticut RSIP)

✅ You pay the utilities (or use a solar-included rent structure that passes through the benefit as rent premium)

✅ You plan to hold the property for 5+ years (to avoid Section 48 ITC recapture)

✅ The property is in an Energy Community zone (40% ITC dramatically improves the return)

✅ Tenant turnover is a concern — solar improves tenant quality and reduces vacancy-related losses

Solar is less advantageous when: you have no passive income to absorb the tax benefits, you're in a low-rate state without above-ITC incentives, the property's roof is in poor condition, or you plan to sell within 3 years.
