Solar Lease vs. Purchase in North Carolina: Key Considerations

Homeowners and businesses evaluating solar in North Carolina face a foundational decision before a single panel is installed: whether to lease the system or purchase it outright (or through a loan). That choice determines who owns the equipment, who claims incentives, and how financial returns accumulate over the system's 25-to-30-year life. This page defines each acquisition model, explains how each operates under North Carolina's regulatory and utility environment, maps the scenarios in which each performs best, and identifies the boundaries where one option clearly outperforms the other.

Definition and scope

Solar purchase means the property owner acquires the photovoltaic system — either with cash or through a solar loan — and holds title to the equipment from installation forward. The owner bears maintenance responsibility and captures all financial benefits, including the federal Investment Tax Credit (ITC), any applicable North Carolina property tax exemption, and the North Carolina sales tax exemption on qualifying equipment.

Solar lease (and the closely related Power Purchase Agreement, or PPA) means a third-party developer owns the system installed on the property. The property owner either pays a fixed monthly lease payment or, in a PPA structure, pays a per-kilowatt-hour rate for the electricity the system generates. Ownership of incentives stays with the developer.

A Power Purchase Agreement differs from a lease in one structural way: under a lease, the customer pays for the system regardless of output; under a PPA, the customer pays only for measured generation. Both structures are offered by developers operating in North Carolina, and both fall outside the ITC eligibility window for the host property owner.

This page covers residential and small commercial solar acquisition decisions governed by North Carolina statutes, North Carolina Utilities Commission (NCUC) rules, and applicable federal tax code provisions. It does not cover large-scale utility or wholesale power arrangements, community solar subscription structures (addressed separately at community solar programs in North Carolina), or acquisition decisions in adjacent states.

How it works

Purchase pathway

1. System sizing and proposal — An installer assesses roof condition, shading, and load data. (See residential solar system sizing in North Carolina for sizing methodology.)
2. Permitting — The installer pulls an electrical and building permit from the local jurisdiction. North Carolina does not have a single statewide solar permit form; each county or municipality administers its own process. Inspection concepts are covered in detail at permitting and inspection concepts for North Carolina solar energy systems.
3. Installation and interconnection — After installation, the system must receive utility interconnection approval. Duke Energy and Dominion Energy each administer their own interconnection queues; the North Carolina utility interconnection process explains timelines and documentation requirements.
4. Incentive capture — The owner files for the federal ITC (26 U.S.C. § 48, administered through IRS Form 3468 or 5695 for residential filers) in the tax year the system is placed in service. North Carolina's property tax exemption is applied through the county assessor under N.C. Gen. Stat. § 105-275(45).
5. Net metering credits — Excess generation flows to the grid under NCUC net metering rules. Net metering policy in North Carolina covers current compensation structures.

Lease/PPA pathway

1. Third-party developer agreement — The property owner signs a 20-to-25-year contract. Contract terms specify payment escalators, early termination fees, and transfer conditions on home sale.
2. Developer-managed permitting — The developer handles permitting as system owner; the property owner signs consent documents.
3. Interconnection — The developer submits interconnection applications to the utility. The property owner's obligation is site access and utility account coordination.
4. Incentive retention — The developer claims the federal ITC and any accelerated depreciation benefits (under MACRS, 26 U.S.C. § 168). The property owner receives none of these incentives directly.
5. Ongoing payments — The owner pays the contracted lease rate or PPA rate, which may include an annual escalator of 1–3% depending on the contract.

Common scenarios

Scenario 1 — High tax liability, sufficient capital: A property owner with a federal tax liability of $8,000 or more who can pay cash or qualify for a low-interest solar loan realizes the full ITC benefit. The 30% federal ITC rate (as set by the Inflation Reduction Act of 2022, IRS Notice 2023-29) on a $20,000 system yields a $6,000 direct tax credit. Over 25 years, this scenario typically produces the highest net return.

Scenario 2 — Limited upfront capital, moderate tax liability: A homeowner who cannot pay cash but has adequate credit history may access a solar loan. Loan-financed systems still qualify for the ITC; the credit can be applied to reduce outstanding principal in year one if the lender permits it.

Scenario 3 — Minimal tax liability or rental property: A property owner with low or no federal tax liability — common among retirees on fixed income or owners of rental properties who cannot claim residential credits — may find a lease or PPA more attractive because the developer monetizes the ITC on their behalf and passes a portion of that value through reduced electricity rates.

Scenario 4 — Near-term home sale: A lease creates a contractual encumbrance. Buyers must qualify to assume the lease, and some refuse. A purchased system, by contrast, can increase sale price.

Decision boundaries

The table below summarizes the structural distinctions between purchase and lease/PPA across the dimensions that most affect North Carolina property owners.

Key decision boundary — payback period: Purchased systems in North Carolina achieve payback in 7 to 12 years depending on system size, shading, and local utility rate, according to data aggregated by the NC Clean Energy Technology Center. Lease and PPA structures offer immediate bill savings with no upfront cost but typically produce lower lifetime savings than ownership.

Key decision boundary — incentive stacking: North Carolina does not offer a standalone state income tax credit for solar (the prior state credit expired in 2015 under Session Law 2015-264). Owners who purchase stack federal ITC benefits against zero competing state credit. Developers who lease stack federal ITC plus MACRS depreciation — advantages that do not flow to lessees.

Scope and limitations: The analysis on this page applies to North Carolina residential and small commercial properties subject to NCUC jurisdiction, IRS federal tax rules, and applicable county-level permitting requirements. It does not apply to properties in federally regulated territories, tribal lands with separate sovereign authority, or commercial projects subject to PURPA wholesale power rules. Legal and tax outcomes vary by individual financial situation; the framing here is informational and structural, not advisory.
