Solar photovoltaic systems for residential properties have experienced explosive growth throughout 2024 and into 2025 as renewable energy adoption accelerates statewide. North Carolina ranks among the top states nationally for solar installations, with thousands of new residential systems being added each year. This rapid expansion has created numerous questions and ongoing uncertainty around licensing and permitting requirements for these installations. To address these regulatory concerns, state licensing boards established updated guidelines in 2022 that continue to provide the foundational framework, though the general contractor licensing threshold has since been updated by statute in 2023.
Solar panel systems are officially designated as Solar Photovoltaic Systems (SPVP). State regulations mandate that a building permit must be obtained for any construction, installation, repair, replacement, or modification to a building or real property when the project cost exceeds $20,000, as outlined in N.C. Gen. Stat. § 143-138(b5). Many municipalities have raised this threshold to align with the general contractor licensing requirement, which currently stands at $40,000 as of October 2023. Building permits for projects surpassing the $40,000 mark must typically be obtained by licensed general contractors, with limited exceptions.
Beyond the building permit, additional trade-specific permits are generally required when a project involves electrical, plumbing, or mechanical components, irrespective of the project's total cost. For instance, electrical permits are mandatory regardless of project value when the work includes adding, replacing, or modifying electrical wiring, appliances, or equipment beyond simple like-kind replacements of electrical devices and lighting fixtures.
This regulatory framework raised an important question: Can a licensed electrician who lacks a general contractor license obtain a building permit for a residential solar panel installation? Or must a licensed general contractor secure the building permit for residential solar installations exceeding $40,000? The state's Office of State Fire Marshall (OSFM), which oversees the State Building Code, along with the relevant licensing boards, issued guidance addressing this matter in 2022. While the original guidelines referenced a $30,000 threshold, the general contractor licensing statute was amended in October 2023, raising the requirement to $40,000.
During the summer of 2022, the OSFM, the State Licensing Board for General Contractors, and the State Board of Examiners of Electrical Contractors collaboratively released Solar Panel Installation Licensing & Permitting Guidelines. These guidelines establish the foundational standards that continue to govern solar installations today, with one important statutory update.
The State Board for General Contractors classifies SPVP installations for residential or commercial structures as electrical work, unless the project scope encompasses structural or other improvements that involve work normally performed by licensed general contractors under board regulation. Originally, the guidelines referenced a $30,000 threshold for when such structural work would trigger general contractor requirements. However, effective October 1, 2023, N.C. Gen. Stat. § 87-1 was amended, raising the general contractor licensing threshold to $40,000 for all construction projects.
Additionally, the guidelines specify that SPVP installations of any monetary value require an electrical contractor license.
Consequently, building permits for solar installations on either residential or commercial properties may now be issued directly to licensed electricians. The accompanying electrical permit can likewise be obtained by the licensed electrician.
The sole exception to this guideline applies when non-electrical improvements exceed $40,000.00 in cost. The cost of other improvements presumably encompasses expenses for alterations or attachments to structures needed to accommodate and secure the solar panels. When such non-electrical improvements surpass $40,000.00, a licensed general contractor must complete that specific portion of the work.
The guidelines provide a crucial additional clarification. When a general contractor must participate due to non-electrical improvements exceeding $40,000, the general contractor is not obligated to obtain the building permit. The licensed electrician may still secure the building permit, with the general contractor serving as a subcontractor to the licensed electrician. This clarification represents a significant departure from typical practice, where the licensed general contractor must both contract directly with the property owner and obtain the building permit.
As of 2025, despite the guidelines being published three years ago in 2022 and the statute being amended in 2023, their application remains inconsistent across local building and inspection departments throughout the state. Some jurisdictions like Raleigh and Greensboro continue to require general contractors to pull building permits for solar panel projects valued above the statutory threshold. Other localities have fully adopted the updated guidelines and statutory changes, now permitting licensed electricians to obtain these permits. This ongoing variation underscores the importance of avoiding common permit mistakes and verifying specific requirements with local authorities before beginning any solar installation project.
Understanding these licensing and permitting requirements has become increasingly critical for homeowners and contractors as solar installations surge in popularity. The average residential solar panel system in North Carolina costs between $11,000 and $21,000 before incentives, with many installations falling just below or above the crucial $40,000 threshold when considering larger systems or additional structural work.
Financial incentives add urgency to proper permitting. The federal Residential Clean Energy Credit currently offers a 30% tax credit on the total system cost, including equipment, labor, and permitting fees. However, this incentive is scheduled to be eliminated entirely after December 31, 2025, creating a tight timeline for homeowners considering solar installations. Properly permitted projects that break ground before the deadline can still claim this substantial credit, potentially saving homeowners $3,500 to $6,000 or more on their solar investment.
Working with correctly licensed professionals who understand both the 2022 guidelines and the 2023 statutory updates ensures projects move forward without delays. Permit rejections or corrections can add weeks or months to project timelines, potentially causing homeowners to miss the federal tax credit deadline. As solar adoption continues to accelerate through 2025, knowing whether a licensed electrician or general contractor should pull permits can streamline the approval process and help homeowners capture available incentives before they expire.

Understanding the licensing and permitting requirements for solar panel installations remains essential for property owners, contractors, and electricians throughout the state as we move through 2025. The 2022 guidelines represent a significant milestone in clarifying the regulatory landscape for solar photovoltaic system installations, and the 2023 statutory amendment raising the general contractor threshold to $40,000 further refined these requirements. By recognizing SPVP installations primarily as electrical work, the framework streamlines the permitting process and allows licensed electricians to take on more comprehensive roles in solar projects.
Property owners planning solar installations in 2025 should verify the specific requirements with their local building departments, as implementation practices continue to vary by jurisdiction. The urgency to act has intensified with the December 31, 2025 deadline for the federal solar tax credit, making proper permitting and timely completion more important than ever. Working with properly licensed professionals who understand both the guidelines and current statutory requirements ensures compliance and helps avoid potential delays or complications during the installation process.

What is the cost threshold that requires a building permit for solar panel installations in North Carolina?
A building permit is required for any construction, installation, repair, replacement, or alteration to a building or real property costing more than $20,000 according to state statute. However, many local building departments have raised this threshold to align with the general contractor licensing requirement, which was increased to $40,000 in October 2023.
Can a licensed electrician pull a building permit for a solar panel installation without a general contractor license?
Yes, according to the 2022 guidelines, licensed electricians can pull building permits for solar panel installations on both residential and commercial properties. The State Board for General Contractors considers SPVP installations to be electrical work, allowing licensed electricians to obtain both the building permit and the electrical permit for these projects.
When is a general contractor required for a solar panel installation project?
A licensed general contractor is required when the cost of non-electrical improvements exceeds $40,000. This includes structural alterations or attachments to accommodate and secure the solar panels. However, even in these cases, the general contractor can work as a subcontractor to the licensed electrician, who may still pull the building permit.
Do all solar panel installations require an electrical permit?
Yes, all SPVP installations require an electrical contractor license and an electrical permit, regardless of the project's total value. This requirement applies because solar panel installations involve adding or modifying electrical systems, which falls under the scope of work requiring electrical permits. Understanding utility interconnection requirements is also essential for grid-connected systems.
Why is there urgency to install solar panels before the end of 2025?
The federal Residential Clean Energy Credit, which provides a 30% tax credit on solar installation costs, is scheduled to be eliminated after December 31, 2025. This credit can save homeowners $3,500 to $6,000 or more on their solar investment. Understanding proper licensing and permitting requirements helps ensure projects are completed on time to qualify for this significant incentive before it expires. For off-grid systems or alternative configurations, different considerations may apply.
Do solar permit requirements vary by city in North Carolina?
Yes, solar permit requirements can vary significantly between municipalities throughout North Carolina. While the state provides overarching guidelines through the 2022 framework and the $40,000 statutory threshold established in 2023, local jurisdictions have discretion in how they implement these rules. Some areas like coastal counties or rural jurisdictions may have specific requirements based on their building codes and environmental considerations. It's essential to confirm requirements with your specific local building department before beginning a project. For support with DIY solar projects, understanding liability and insurance requirements is equally important.
