Community Solar Programs Available in North Carolina

North Carolina's community solar landscape operates at the intersection of utility regulation, state energy policy, and subscriber contract law — making it one of the more structured renewable energy participation frameworks in the Southeast. This page covers how community solar programs are defined under North Carolina's regulatory environment, how subscription models function mechanically, which scenarios qualify different participant types, and where the boundaries lie between community solar and adjacent program types. Understanding these distinctions matters because subscriber rights, billing credits, and program availability vary significantly by utility territory and program design.

Definition and scope

Community solar, in the context of North Carolina utility regulation, refers to shared solar arrangements in which subscribers receive a proportional credit on their electricity bills based on energy output from a centrally located solar array — without installing generation equipment on their own property. The North Carolina Utilities Commission (NCUC) holds jurisdiction over investor-owned utilities operating these programs, including Duke Energy Carolinas, Duke Energy Progress, and Dominion Energy North Carolina.

The North Carolina Renewable Energy Portfolio Standard (N.C. Gen. Stat. § 62-133.8) established the broader renewable energy framework within which community solar programs operate. Duke Energy's Green Source Advantage and Green Source Rider programs, along with the Duke Energy community solar program in North Carolina, represent the primary structured pathways for non-residential subscribers. Residential access to dedicated community solar subscription products has been more limited compared to states with explicit community solar legislation.

Scope and geographic limitations: This page covers community solar programs regulated by the NCUC and operating under North Carolina state law. It does not address federal solar tax credit structures (covered separately under federal ITC application in North Carolina), programs in neighboring states, or municipal utility territories not subject to NCUC jurisdiction. HOA-level solar sharing arrangements fall outside community solar program definitions and are addressed under HOA solar installation rules in North Carolina.

How it works

Community solar operates through a subscriber model structured around three core phases:

  1. Project development and interconnection — A utility or third-party developer constructs a solar array, typically ranging from 1 MW to 5 MW in capacity for community-scale installations. The array must pass interconnection review under NCUC rules and applicable Duke Energy or Dominion interconnection tariffs, detailed further in the North Carolina utility interconnection process.
  2. Subscription allocation — Eligible customers subscribe to a share of the array's output, measured in kilowatts (kW) or kilowatt-hours (kWh). Subscription sizes are capped — Duke Energy Progress's community solar pilots have historically limited residential subscriptions to a portion of the customer's average annual consumption to prevent over-subscription relative to actual load.
  3. Bill credit application — Monthly production from the subscriber's allocated share is translated into a kilowatt-hour credit applied against that subscriber's utility bill. The credit rate is established by the tariff on file with the NCUC; it is not equivalent to net metering credit rates, which are governed separately under North Carolina net metering policy.

Subscribers do not own the solar panels, do not receive interconnection permits in their name, and carry no maintenance responsibility. This distinguishes community solar from direct ownership models described in the conceptual overview of how North Carolina solar energy systems work.

Common scenarios

Residential renters and condo owners represent the most common use case for community solar. Because rooftop installation is not feasible — either due to lease restrictions or shared roof structures — community solar subscriptions provide bill credit access to solar generation without physical installation. Under Duke Energy's existing pilot structures, eligible residential customers in the utility's service territory can enroll if capacity is available.

Small commercial and nonprofit subscribers can participate in programs structured for non-residential customers. Nonprofits that cannot monetize federal investment tax credits directly sometimes find community solar subscriptions more accessible than direct ownership. The solar for nonprofits in North Carolina page addresses this distinction further.

Low-income households face a specific access gap. Community solar is one mechanism identified by the NCUC and advocacy organizations as a pathway to extend solar bill savings to customers who cannot afford upfront installation costs. The North Carolina low-income solar programs page covers income-qualified program structures separately.

Agricultural operators on large rural parcels sometimes consider community solar as an alternative to ground-mount installation when land use restrictions or financing barriers apply. The comparison between direct ground-mount ownership and subscription participation is covered under agricultural solar in North Carolina.

Decision boundaries

The key classification boundary in North Carolina's framework is community solar versus individual net metering. The two differ along 4 primary dimensions:

Dimension Community Solar Subscription Individual Net Metering
Asset ownership Developer or utility Customer
Installation required No Yes
Credit rate source Program tariff (NCUC-approved) Net metering tariff
Portability Subscription may transfer System is property-bound

A second boundary separates NCUC-regulated programs from municipal utility or electric cooperative programs. Electric cooperatives in North Carolina — such as those operating under the North Carolina Association of Electric Cooperatives — are not subject to NCUC jurisdiction and set their own community solar policies independently. Customers in cooperative territory must verify program availability directly with their cooperative.

The regulatory context for North Carolina solar energy systems provides the statutory and commission-order framework that governs both sets of program types.

Subscription term lengths, early termination provisions, and credit rate structures vary by program. The NCUC's publicly filed tariffs for each investor-owned utility are the authoritative source for current program parameters. Prospective subscribers should review the applicable tariff on file with the NCUC before executing any subscription agreement. Additional program and financial comparisons are available through the North Carolina solar return on investment and solar financing options in North Carolina pages. A broader introduction to solar participation frameworks across the state is available at the North Carolina Solar Authority index.
