North Carolina Solar Laws

North Carolina is steadily emerging as a leader in solar energy across the southeastern United States. The mix of cities and rural areas across the state creates good opportunities for homeowners and businesses to install solar panels. However, anyone considering solar needs to understand the laws that apply to these installations. This guide explains the legal rules and protections for solar energy systems in North Carolina. It covers federal incentives, state laws, HOA regulations, local permits, and solar easement agreements.

Federal Regulations and Policies Affecting Solar Installation in North Carolina

Homeowners and businesses in North Carolina benefit from federal regulations and policies that set the stage for renewable adoption across the country. These policies complement state-level solar panel laws and provide key financial incentives. They include the following:

Federal Investment Tax Credit (ITC)

The Federal Investment Tax Credit (ITC) remains one of the most significant national incentives for solar adoption. It allows system owners in North Carolina to deduct 30% of solar installation costs from federal taxes through 2032. This program reduces upfront expenses and directly supports North Carolina’s solar energy policy, making solar more affordable statewide.

PURPA and Utility Interconnection

The Public Utility Regulatory Policies Act (PURPA) requires electric utilities to purchase power from small renewable energy facilities and allow them to connect to the grid.

Under PURPA, utilities must pay for the power purchased from these facilities at their “avoided cost” (what it would have cost them to generate that electricity themselves or purchase it elsewhere). This federal law has been crucial for North Carolina’s solar industry because it guarantees independent solar developers a market for their electricity.

Federal Energy Regulatory Commission (FERC)

Utility-scale solar projects selling power at wholesale are regulated by the Federal Energy Regulatory Commission (FERC). The FERC provides market-based rate authorization, which allows utility-scale solar developers in North Carolina to sell electricity at competitive market prices without having to justify their rates on a cost basis.

North Carolina Solar Regulations and Policies

North Carolina has implemented several regulations and policies to encourage solar energy growth in the state. These provisions include the following:

Property Tax Exemption

North Carolina law exempts residential solar systems from property tax increases. If a homeowner installs solar panels, the added property value does not increase their property taxes. Commercial solar systems also receive an 80% exemption, meaning only 20% of the system’s added value counts toward property taxes.

State Tax Credit History

North Carolina offered a state tax credit for renewable energy systems until December 2015. During this period, the credit helped grow the state’s solar industry. After the credit expired, North Carolina remained one of the leading solar energy states in the Southeast.

Net Metering Rules

State law requires electric utilities to offer net metering to customers with solar systems. Net metering allows solar customers to send excess electricity back to the grid in exchange for credits on their electric bills. These credits offset the cost of power drawn from the grid when the solar system is not producing enough electricity. Compensation rates differ by utility provider.

Renewable Energy and Energy Efficiency Portfolio Standard (REPS)

North Carolina was the first state in the Southeast to require utilities to generate a portion of their electricity from renewable sources. This standard, known as the Renewable Energy and Energy Efficiency Portfolio Standard (REPS), mandates all major utilities operating in North Carolina to use renewable energy sources like solar.

North Carolina HOA Solar Laws

North Carolina law limits the authority of homeowners’ associations over solar panel installations. HOAs cannot completely prohibit solar systems on residential properties. However, they may impose certain restrictions on panel placement, appearance, or installation methods.

Community Solar Programs

Community solar programs allow residents to access solar energy without installing panels on their property. Participants purchase or lease a portion of the electricity generated by a shared solar facility. The electricity produced from their share is credited to their utility bill each month. This option is available to renters, residents with shaded roofs, or those whose properties are unsuitable for solar panel installation.

Does North Carolina Have Solar Access Laws?

Yes. North Carolina law includes solar access protections and provisions for solar easement agreements. These laws address property owners’ rights to sunlight for solar energy systems.

Solar access laws establish the rights of property owners to install and operate solar energy systems. In North Carolina, these laws place limits on restrictions that HOAs and local governments can impose on solar installations.

Solar easements, on the other hand, are voluntary legal agreements between neighboring property owners. An easement allows one property owner to protect their access to sunlight by preventing obstructions on an adjacent property. These agreements are typically recorded in property deeds and remain with the property when it is sold.

North Carolina Solar Access Laws

North Carolina’s solar access protections are outlined in North Carolina General Statute §22B-20. This statute invalidates any covenant or restriction that completely prohibits solar collectors on residential property. However, HOAs may still impose reasonable requirements regarding system placement and appearance.

Do You Need Permits for Solar Installation in North Carolina?

Yes, homeowners must obtain permits before installing solar systems. These solar panel installation regulations vary across municipalities, but are universally required to ensure compliance with safety standards.

Types of Permits Required

  • Electrical Permit: Ensures the system meets state electrical safety codes
  • Building Permit: Confirms structural integrity for rooftop installations
  • Zoning Approval: Required in some areas for land-use compliance
  • Utility Interconnection Approval: Necessary for grid-tied systems under net metering programs

How to Obtain Permits for Solar Installation in North Carolina

Before starting a solar installation, it is essential to secure the proper permits. This step ensures compliance with North Carolina solar laws and local building codes. Homeowners and businesses in the state hoping to obtain solar permits may be required to contact the following organizations:

Obtaining a solar permit typically involves these steps:

  • Site Assessment: Hire a licensed solar contractor to evaluate your roof and electrical system
  • Design Submission: Submit detailed plans to your local building department, including roof layout, mounting details, and electrical diagrams
  • Permit Application: Apply for building and electrical permits. Many municipalities offer online portals for faster processing
  • HOA Approval (if applicable): If you live in an HOA-governed community, submit your plans to the Architectural Review Committee. Under North Carolina HOA solar laws, they cannot deny your request without a valid justification
  • Utility Interconnection: Submit an application to your utility provider detailing system specs and expected output. Approval is required before grid connection
  • Inspection Scheduling: After installation, schedule inspections to verify code compliance
  • Permission to Operate (PTO): Once inspections are passed, your utility provider will issue PTO, allowing you to activate your solar system.
