Solar Energy Systems for Nonprofits in North Carolina

Nonprofit organizations in North Carolina face a structural challenge when pursuing solar energy: most federal and state solar incentives are structured as tax credits, which nonprofits cannot use because they have no tax liability. Despite that constraint, a defined set of financing structures, direct-pay mechanisms, and grant programs make solar installation financially viable for hospitals, houses of worship, universities, and other 501(c)(3) entities. This page covers the definition and scope of nonprofit solar in North Carolina, how the major financing and ownership models function, the scenarios where each model applies, and the decision boundaries that determine which approach fits a given organization.

Definition and scope

Nonprofit solar refers to the installation and operation of photovoltaic (PV) or solar thermal systems on property owned or occupied by tax-exempt organizations recognized under Internal Revenue Code §501(c)(3), §501(c)(4), or equivalent classifications. In North Carolina, this category encompasses charitable organizations, religious institutions, educational nonprofits, hospitals, and government entities such as municipalities and public school systems.

The relevance of nonprofit classification is primarily financial. The federal Investment Tax Credit (ITC) — codified under 26 U.S.C. §48 — historically required tax liability to monetize the credit. The Inflation Reduction Act of 2022 (IRA) introduced a direct-pay provision (also called "elective pay") under IRC §6417, which allows tax-exempt entities to receive the ITC equivalent as a cash payment from the IRS rather than a credit offset. As of the 2023 tax year, eligible nonprofit and governmental entities can claim 30% of qualified solar installation costs through this mechanism.

North Carolina state-level incentives for solar are covered in the broader regulatory context for North Carolina solar energy systems. The state does not offer a dedicated nonprofit solar grant program through a single agency, but nonprofits may access the North Carolina solar property tax exemption for the added value solar places on real property, and the North Carolina solar sales tax exemption on equipment purchases applies regardless of tax-exempt status.

Scope limitations: This page addresses North Carolina-specific regulatory and financial considerations. Federal tax law, IRS elective pay procedures, and USDA rural energy grant programs exist at the federal level and are referenced here only as they interact with North Carolina nonprofit operations. Entities operating across multiple states, or nonprofits with facilities in Virginia or South Carolina, must apply the rules of each relevant jurisdiction separately.

How it works

Because nonprofits cannot directly monetize tax credits, four primary ownership and financing structures have emerged for nonprofit solar in North Carolina. Each structure transfers or eliminates the tax-credit dependency in a different way.

1. Direct ownership with IRA elective pay — The nonprofit owns the system outright, files IRS Form 3800 and the applicable elective-pay election, and receives a direct payment equal to 30% of eligible costs. Bonus adders (domestic content, energy community, low-income community) can raise the effective rate to 40–50% under IRS Notice 2023-29. The organization handles permitting, interconnection, and ongoing maintenance.
2. Power Purchase Agreement (PPA) — A third-party developer owns, installs, and maintains the system on the nonprofit's property. The nonprofit purchases the electricity generated at a contracted rate, typically below the local utility's retail rate. The developer claims the ITC. North Carolina's utility interconnection process governs how PPA systems connect to the Duke Energy or Dominion Energy grid.
3. Solar lease — Structurally similar to a PPA but the nonprofit pays a fixed monthly lease payment rather than a per-kilowatt-hour rate. For a detailed comparison, see North Carolina solar lease vs. purchase.
4. Community solar subscription — Where physical installation is not feasible (leased space, structurally unsuitable roofs), nonprofits can subscribe to a community solar program and receive a bill credit proportional to their share of a shared array.

The how North Carolina solar energy systems work conceptual overview covers the underlying photovoltaic technology common to all four structures.

Permitting and inspection: All grid-tied systems require a building permit from the applicable county or municipal authority, an electrical permit, and an inspection by a licensed electrical inspector before the utility will authorize interconnection. The North Carolina Utilities Commission (NCUC) regulates interconnection standards, and the National Electrical Code (NEC), specifically Article 690, governs PV system wiring safety. Systems above 25 kW AC typically require a licensed electrical engineer to stamp drawings submitted for permit.

Common scenarios

Houses of worship and community centers — These facilities typically have large flat or gently pitched roofs and predictable daytime electricity loads. A direct-ownership model using IRA elective pay is common where the organization has reserves to cover upfront costs (often $80,000–$400,000 for a 50–250 kW system) and wants long-term cost certainty.

Hospitals and health systems — Larger energy consumers with complex electrical infrastructure often use PPAs to avoid capital expenditure and operations risk. A hospital consuming 2–10 million kWh annually may negotiate a PPA for a 500 kW to 2 MW rooftop or ground-mount system. Ground-mount options are detailed in solar carports and ground-mount systems in North Carolina.

Schools and universities — Public school systems, as governmental entities, qualify for IRA elective pay under the same §6417 framework as 501(c)(3) organizations. The Duke Energy solar program in North Carolina includes specific tariff structures that affect grid-tied school installations served by Duke's territory.

Low-income service organizations — Nonprofits whose primary mission serves low-income populations may qualify for the IRA's Low-Income Communities Bonus Credit, a 10-percentage-point adder to the base ITC rate, administered through an annual application process at the U.S. Department of Energy. Additional pathways are covered in North Carolina low-income solar programs.

Agricultural nonprofits — Land trusts and agricultural nonprofits may deploy agricultural solar configurations and are eligible for USDA Rural Energy for America Program (REAP) grants, which can cover up to 50% of project costs (USDA REAP).

Decision boundaries

Selecting the correct structure requires evaluating four intersecting factors:

Tax credit monetization capability — Organizations that have recently gained 501(c)(3) status or have significant unrelated business income may have partial tax liability. A tax attorney review determines whether elective pay, direct monetization, or a third-party ownership model is more efficient.

Capital availability — Direct ownership with elective pay produces the best long-term economics but requires upfront capital. A 100 kW system in North Carolina typically costs $150,000–$250,000 before incentives at 2023 commercial installation rates. If capital reserves are below that threshold, a PPA or lease eliminates upfront cost.

Property control — A nonprofit that leases its facility cannot encumber the property with a solar lien or long-term PPA without landlord consent. Leased-space organizations are limited to portable systems, community solar subscriptions, or negotiated landlord-install arrangements. Solar financing options covers the lender and PACE financing constraints relevant to leased property.

System size and utility territory — North Carolina's two dominant investor-owned utilities, Duke Energy Carolinas/Duke Energy Progress and Dominion Energy North Carolina, each have distinct interconnection rules, standby charges, and net metering successor tariffs as governed by NCUC rules. Systems above 1 MW enter a different interconnection queue with longer timelines and higher study costs.

The following comparison summarizes key structural differences:

The North Carolina solar return on investment analysis framework applies to nonprofit projects with the modification that elective pay replaces the standard ITC offset in financial modeling. For organizations evaluating battery storage integration, the IRA also extended elective pay to standalone storage systems installed alongside qualifying solar projects.
