Maryland Solar Lease vs. Purchase Comparison
Maryland homeowners and commercial property owners face a foundational financing decision before any solar installation begins: leasing the system or purchasing it outright. This page compares the two primary ownership structures — solar leases and direct purchases (including loan-financed purchases) — across financial outcomes, incentive eligibility, permitting implications, and long-term risk profiles specific to Maryland's regulatory environment. Understanding these distinctions shapes whether a property owner captures the full value of Maryland's incentive stack or transfers that value to a third party.
Definition and scope
A solar lease is a contractual arrangement in which a third-party company owns the photovoltaic (PV) system installed on a property, and the property owner pays a fixed monthly fee — or a rate tied to energy production — to use that system. No capital changes hands at installation; the lessor retains ownership, depreciation rights, and eligibility for ownership-based incentives.
A solar purchase transfers full ownership to the property owner at the point of sale. Purchases may be cash-financed or loan-financed (through a home equity loan, a dedicated solar loan, or Maryland-specific lending programs). The owner holds title to the equipment, assumes maintenance responsibility, and qualifies directly for incentive programs tied to system ownership.
Maryland solar financing options covers the full range of instruments available in the state, including PACE financing and credit union solar loan products.
Scope and coverage: This page applies to residential and commercial solar installations subject to Maryland jurisdiction — principally governed by the Maryland Public Service Commission (PSC), the Maryland Energy Administration (MEA), and applicable county permitting authorities. It does not address federal tax treatment in depth, does not constitute legal or tax advice, and does not cover installations sited in other states or on federal lands. Properties in Maryland governed by homeowners' association rules may face additional constraints addressed separately at Maryland HOA rules and solar installations.
How it works
Solar lease mechanics
Under a lease, the installing company handles equipment procurement, installation, and ongoing maintenance. The property owner signs a contract — typically 20 to 25 years in duration — specifying either a fixed monthly payment or a per-kilowatt-hour rate. At contract end, options generally include purchase of the system, lease renewal, or system removal at the company's expense.
Because the third-party owner holds title, that entity captures:
- The Federal Investment Tax Credit (ITC) — set at 30% of system cost under the Inflation Reduction Act (IRA) (U.S. Department of Energy, DSIRE)
- Maryland Solar Renewable Energy Credits (SRECs) — tradeable certificates generated by the system (Maryland PSC, SREC program)
- Accelerated depreciation benefits under MACRS if the lessor is a commercial entity
The property owner receives none of these directly. The lease rate may be discounted to reflect these captured incentives, but the discount is determined by the lessor's pricing model, not by statute.
Purchase mechanics
A direct purchase — cash or financed — places the ITC, SREC revenue, and any applicable MEA rebates with the property owner. The Federal Investment Tax Credit for Maryland residents page details qualification criteria. SRECs generated by a Maryland-owned system can be sold through the SREC market, which the PSC administers under the Renewable Portfolio Standard (Maryland RPS statute, Md. Code, Public Utilities § 7-701 et seq.).
Permit and interconnection filings are required under either structure. The installing entity — whether a lessor's contractor or an owner-hired contractor — must hold a Maryland Home Improvement Contractor (MHIC) license and, for electrical work, a licensed Master Electrician credential. County building permits and utility interconnection approval from the relevant Maryland electric distribution company (Pepco, BGE, Delmarva, or SMECO) are required regardless of ownership structure (Maryland Utility Interconnection Requirements).
Common scenarios
Scenario 1 — Low upfront capital, credit-qualified household:
A household with strong credit but limited liquid savings can access a solar loan at competitive rates, capturing the ITC and SREC revenue while avoiding the 20-year contractual transfer of incentives. Loan terms from 10 to 25 years are common in Maryland's market.
Scenario 2 — Tax liability too low to absorb ITC:
A retired homeowner with little federal tax liability in a given year may not benefit fully from the 30% ITC in year one (though unused credit carries forward). In this scenario, a lease transfers the tax optimization burden to the third party, potentially making the lease rate more attractive than it would appear at face value.
Scenario 3 — Property sale during lease term:
When a leased system's property is sold, the lease must be transferred to the buyer or paid off at sale. Some buyers decline to assume lease obligations, complicating the transaction. Purchased systems — whether cash or loan-financed — do not carry this contractual transfer requirement, though outstanding loan balances must be addressed at closing. Maryland solar energy and property values covers how each structure affects assessed value and buyer behavior.
Scenario 4 — Commercial property with tax appetite:
A commercial owner with significant tax liability can fully absorb the ITC and apply MACRS depreciation over a 5-year schedule, making outright purchase the dominant financial structure in commercial solar transactions in Maryland.
Decision boundaries
The table below structures the primary decision factors:
| Factor | Lease | Purchase (Cash/Loan) |
|---|---|---|
| Upfront cost | $0 | $15,000–$35,000+ typical range |
| ITC eligibility | Lessor captures | Owner captures (30% of system cost) |
| SREC revenue | Lessor captures | Owner captures |
| MEA rebate eligibility | Lessor captures | Owner captures |
| Maintenance responsibility | Lessor | Owner |
| System ownership at end of term | Lessor (unless bought out) | Owner from day one |
| Property sale complexity | Lease transfer required | Standard disclosure only |
| Contract length | 20–25 years typical | No ongoing obligation post-payoff |
Key boundary conditions that shift the optimal structure:
- Tax liability threshold: Property owners who cannot use the ITC within the 5-year carryforward window should model the after-tax economics of a lease against a purchased system with a solar loan.
- Horizon length: Owners planning to sell within 5 years face the highest lease-complication risk; purchase structures impose no similar transactional friction.
- SREC market participation: Maryland's SREC market requires the system owner to register. Leased systems credit SRECs to the lessor. Owners interested in direct SREC revenue must hold title. See Maryland Solar Renewable Energy Credits (SRECs) for registration procedures.
- Incentive stacking: Maryland's net metering rules (Maryland Net Metering Explained) credit the account holder for excess generation. Both lease and purchase customers receive net metering credits on their utility bill, but the economic value differs because leased customers are paying a separate lease fee against those credits.
- Battery storage add-ons: Adding a battery storage system under a lease raises contractual complexity around ownership and warranty. Purchased systems allow the owner to qualify independently for any applicable storage incentives. Solar battery storage in Maryland addresses the incentive landscape for paired systems.

Regulatory oversight of both lease and purchase transactions falls under the Maryland PSC and MEA frameworks detailed at regulatory context for Maryland solar energy systems.
