Solar Financing Options for North Carolina Homeowners
North Carolina homeowners exploring solar installation face a structured set of financing mechanisms, each carrying distinct ownership implications, tax treatment, and long-term cost profiles. This page covers the four primary financing categories — cash purchase, solar loans, solar leases, and power purchase agreements (PPAs) — along with the state and federal incentive layers that interact with each. Understanding how these structures differ is essential before committing to any installation agreement.
Definition and scope
Solar financing refers to the legal and financial arrangements that determine how a homeowner acquires access to a photovoltaic (PV) system — whether through direct ownership, debt instruments, or third-party ownership contracts. In North Carolina, financing choice directly affects eligibility for the federal Investment Tax Credit (ITC), the state property tax exemption, and the sales tax exemption established under North Carolina General Statutes § 105-275(45) and § 105-164.13.
The North Carolina Utilities Commission (NCUC) and the North Carolina Clean Energy Technology Center (NCCETC) both publish guidance relevant to solar financing decisions. Duke Energy and Dominion Energy — the state's two dominant investor-owned utilities — administer interconnection and net metering programs that interact directly with how financed systems are credited for exported electricity. Detailed interconnection requirements are governed by NCUC dockets and described further at .
Scope and coverage: This page applies to residential solar financing within North Carolina's jurisdiction. It does not address commercial or utility-scale financing structures (covered at commercial solar systems), nor does it constitute legal, tax, or financial advice. Financing terms set by federal agencies — including the IRS rules governing the 30% ITC under 26 U.S.C. § 48(a) — apply nationally but are addressed here only in their North Carolina application context.
How it works
Solar financing structures fall into two broad ownership categories: homeowner-owned and third-party-owned.
Homeowner-owned structures:
- Cash purchase — The homeowner pays the full system cost upfront. Median residential system costs in North Carolina range from $25,000 to $35,000 before incentives, according to NCCETC's U.S. Solar Power Rankings. The homeowner captures 100% of the federal ITC, the NC property tax exemption, and all net metering credits directly.
- Solar loan — A secured or unsecured loan finances the purchase. The homeowner retains system ownership and ITC eligibility. Loan products include home equity loans, home equity lines of credit (HELOCs), dedicated solar loans through the North Carolina Energy Efficiency Revolving Loan Fund administered by the North Carolina Department of Commerce's Energy Division, and lender-specific products. Interest rates and term lengths vary by lender and credit profile; the NC Energy Efficiency Revolving Loan Fund has historically offered terms up to 10 years for qualified applicants.
Third-party-owned structures:
- Solar lease — A solar company retains system ownership and leases the equipment to the homeowner for a fixed monthly payment over a term typically ranging from 20 to 25 years. The homeowner does not claim the ITC; the installer does. A detailed comparison of lease versus purchase economics is available at .
- Power Purchase Agreement (PPA) — The homeowner pays per kilowatt-hour for electricity the system produces at a contracted rate, rather than paying for the equipment. The installer owns, operates, and maintains the panels. PPA availability in North Carolina is subject to NCUC regulatory review, and not all utilities in the state permit third-party PPA arrangements for residential customers.

Common scenarios
Scenario 1: High-equity homeowner pursuing maximum ROI A homeowner with significant home equity uses a HELOC to finance a $28,000 system. The 30% federal ITC generates an $8,400 tax credit in the installation year (IRS Form 5695). The NC property tax exemption prevents the system's added home value from increasing annual property tax assessments. Net metering under Duke Energy's solar program credits exported kilowatt-hours against future bills, shortening effective payback.
Scenario 2: Low-to-moderate income household A homeowner who cannot monetize the ITC through tax liability may benefit from income-qualified programs. The NC Green Power program and North Carolina low-income solar programs offer alternative pathways. The USDA Rural Energy for America Program (REAP) may apply to rural North Carolina properties.
Scenario 3: HOA-restricted property North Carolina General Statutes § 22B-20 limits HOA authority to restrict solar installations outright, though placement rules may apply. Financing in this context does not change, but the installation timeline may extend pending HOA review. See HOA solar installation rules for scope details.
Scenario 4: Homeowner considering battery storage Adding battery storage affects financing structure because storage components may qualify for a separate ITC calculation or must be integrated into the original system application. Details on storage-specific incentives are available at .
Decision boundaries
The choice between ownership and lease/PPA structures hinges on 4 primary variables:
- Tax liability — Only homeowners with sufficient federal tax liability can fully monetize the 30% ITC. Leases and PPAs transfer that benefit to the installer.
- Credit profile — Solar loan eligibility depends on creditworthiness; cash and HELOC options require existing equity or liquid capital.
- Transferability — Leases and PPAs attach to the property and require buyer assumption upon sale, which can complicate real estate transactions. Owned systems typically increase home value, as noted in analyses from .
- Permitting and inspection obligations — Regardless of financing type, all North Carolina residential solar installations require electrical permits and inspections through local building departments, subject to the North Carolina State Building Code and NEC Article 690. Financing structure does not alter permitting obligations.
