Going solar is one of the best decisions a homeowner can make, but the permitting process stops many people before they even start. Between building permits, electrical permits, utility approvals, and HOA rules, it can feel like there is a lot standing between you and your first day of solar production.
The good news is the process is manageable, especially when you work with an experienced installer. This guide covers every layer of the regulatory landscape, including the most important policy updates, so you can move forward with confidence.
Key Points
- Solar installations require building permits, electrical permits, and utility interconnection approval in virtually every jurisdiction.
- The 30% federal residential solar tax credit (Section 25D) expired on December 31, 2025. Homeowners buying or financing a system in 2026 have no federal tax credit available. Solar leases and PPAs may allow the system owner to claim a commercial credit (Section 48E), which some providers pass through as lower payments, but homeowners cannot claim it directly.
- North Carolina law protects homeowners’ right to install solar even in HOA communities, under N.C. General Statute 22B-20.
- North Carolina is phasing out traditional net metering. Existing systems are grandfathered through December 31, 2026; new installs are subject to updated compensation structures.
- Duke Energy’s PowerPair program offers up to $9,000 in combined solar and battery rebates for eligible NC homeowners.
- Understanding the permits and regulations is essential before installation. Working with a knowledgeable local installer like 8MSolar removes most of the complexity.
What Permits Are Required for Solar Installation?
Most homeowners are surprised to learn that solar installations require multiple permits, not just one. Here is what you will typically need:
- Building Permit: Required in almost every jurisdiction. The local building department reviews your system design to confirm it meets structural and fire safety codes.
- Electrical Permit: Required to connect the solar array to your home’s electrical system and to the grid. This ensures all wiring meets the National Electrical Code (NEC) and local standards.
- Zoning Approval: Some municipalities require a separate zoning review, particularly for ground-mounted systems or properties in historic districts.
- Utility Interconnection Approval: Required for any grid-tied system. Your utility company must approve the connection before you can legally turn the system on and begin net metering.
- HOA Approval (if applicable): If you live in an HOA community, you may need to submit plans for approval, though your right to install solar is protected by law in North Carolina.
Each of these steps involves submitting documentation, waiting for review, and in some cases scheduling inspections. A qualified installer handles all of this on your behalf.
Federal Regulations and Incentives
The federal government does not impose installation-specific regulations for residential solar, but it has historically been the biggest source of financial incentives. That landscape changed in July 2025.
The Federal Solar Tax Credit: What Homeowners Need to Know in 2026
On July 4, 2025, President Trump signed the “One Big Beautiful Bill” into law. The IRS confirms that the Residential Clean Energy Credit (Section 25D) is not available for any solar property placed in service after December 31, 2025. There is no phase-down period. If you are buying and owning a solar system in 2026, there is no federal residential tax credit available to you.
Here is an accurate summary of where things stand as of March 2026:
Homeowner-purchased or financed systems (you own the panels): No federal tax credit is available for systems installed in 2026 or later. The 30% Section 25D credit expired on December 31, 2025.
Solar leases and PPAs (a third party owns the panels): The commercial Clean Electricity Investment Credit (Section 48E) is still available to the solar company that owns the system, for projects that begin construction before July 4, 2026 and are placed in service by December 31, 2027. Homeowners cannot claim this credit themselves. Whether and how much of those savings are passed to you depends entirely on the provider and the contract terms. Some providers pass the value through as lower monthly payments; others do not.
Battery storage under third-party ownership: Standalone battery storage under a third-party lease continues to qualify for the Section 48E credit through 2032.
Commercial solar: The Section 48E credit applies to commercial and business installations with a July 4, 2026 construction start deadline and a December 31, 2027 placed-in-service deadline.
The expiration of the residential ITC makes state, local, and utility-level incentives more important than ever for homeowners evaluating the economics of going solar. Solar still delivers strong long-term savings through reduced electricity bills, and North Carolina has meaningful programs still in place.
Note: This is a summary for informational purposes only. Tax rules are complex and individual circumstances vary. Consult a licensed tax professional before making any decisions based on tax incentives.
Department of Energy Programs
The Department of Energy’s Solar Energy Technologies Office (SETO) continues to fund research and development programs aimed at reducing the cost of solar technology over time. These programs do not directly affect individual homeowners but support the long-term affordability of the technology.
State Regulations
State-level rules vary. Here is what is relevant for homeowners in North Carolina and Virginia.
North Carolina
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 mandate has driven solar market development and helps maintain a strong installer ecosystem in the state.
Net Metering Transition Net metering in North Carolina is undergoing a big change. Traditional net metering is being phased out. Existing solar systems are grandfathered under the old rules through December 31, 2026. New installations are subject to updated interconnection policies with different compensation structures, which vary by utility. Duke Energy customers, for example, are moving to a Bridge Rate or time-of-use export compensation model.
Property Tax Exemption North Carolina provides an 80% property tax exemption on the added value that a solar system contributes to your home’s assessed value. This reduces the ongoing cost of owning solar and applies automatically for most residential systems.
Duke Energy PowerPair Program Duke Energy’s PowerPair Solar and Battery Incentive offers eligible homeowners up to approximately $9,000 in combined rebates for installing both a solar system and a compatible battery. This includes a rebate of roughly $0.36 per watt for solar (up to 10 kW) and approximately $400 per kWh for battery storage. Some battery participation programs also provide ongoing monthly bill credits. For more information, see 8MSolar’s guide to the PowerPair Solar and Battery Incentive.
Solar Access Law (N.C. General Statute 22B-20) North Carolina law explicitly protects homeowners’ right to install solar. Any deed restriction, covenant, or HOA rule that prohibits or effectively prohibits the installation of a solar system is void and unenforceable. HOAs may regulate the placement and appearance of panels, but they cannot require placement that significantly reduces system output or drives up costs beyond a reasonable level.
In 2022, the North Carolina Supreme Court reinforced this protection in Belmont Association v. Farwig, confirming that HOAs cannot override the state’s solar access statute. For a full breakdown, see 8MSolar’s article on what the NC Supreme Court ruling means for residential solar.
Other State Incentive Examples
California: The state has implemented online permitting systems and standardized requirements through the Solar Permitting Guidebook, which has reduced approval times and boosted installations.
New York: The NY-Sun Incentive Program supports solar adoption across the state. New York also offers a unified solar permit that standardizes requirements across municipalities, reducing complexity.
New Jersey and Arizona: Both states have historically offered favorable net metering policies, allowing solar panel owners to receive full retail credit for excess electricity they generate back to the grid.
Massachusetts and Colorado: Both have implemented Renewable Portfolio Standards (RPS) that have grown their solar markets.
Local Permits and Building Codes
Local requirements are where the details really matter, and they vary more than most homeowners expect.
Building Permits Most jurisdictions require building permits for solar panel installations. The process involves submitting detailed plans and specifications for the system, which the local building department reviews for compliance with building codes and safety standards.
Electrical Permits An electrical permit is required to connect solar panels to the home’s electrical system and to the local grid. This ensures all work meets the National Electrical Code and local electrical requirements.
Zoning Requirements Zoning laws can affect where and how you install solar panels. There may be restrictions on height, placement, or setback distances, especially in residential areas or historic districts. Ground-mounted systems typically face more scrutiny than rooftop installations.
HOA Rules If you live in an HOA community, you may need to submit plans for approval before installation. In North Carolina, your right to install solar is legally protected, though HOAs may impose reasonable restrictions on placement. Early, open communication with your HOA board and providing detailed plans goes a long way toward a smooth approval.
Steps to Obtain Permits
Here is how the permitting process typically unfolds from start to finish:
- Site Assessment: A professional solar installer visits your property to evaluate roof condition, orientation, shading, and the best configuration for your system.
- Design and Engineering: Detailed plans are created, including electrical diagrams, structural calculations, and a full list of system components.
- Permit Application: Your installer submits permit applications to the local building department, covering building, electrical, and any other required permits.
- Permit Review: The building department reviews submissions for code compliance. This can take anywhere from a few days to several weeks depending on your municipality and current volume.
- Installation: Once permits are approved, the physical installation takes place, typically in one to two days.
- Inspections: Local inspectors review the completed installation to verify it was built to plan and meets all safety codes.
- Utility Interconnection: Your installer submits interconnection paperwork to your utility. Once approved, you receive Permission to Operate (PTO) and can officially turn the system on.
The full process from contract signing to Permission to Operate typically takes six to twelve weeks. Working with an experienced local installer compresses this timeline considerably.
Common Challenges and Solutions
Permit Approval Delays High volumes of solar applications in some areas can slow the review process. An experienced installer who knows local building departments and submits clean, complete applications can significantly reduce wait times.
Complex or Overlapping Regulations When building codes, electrical codes, zoning laws, and HOA rules all apply to the same installation, it can get complicated quickly. A knowledgeable installer who has worked in your specific municipality handles the navigation so you do not have to.
HOA Friction Even with legal protections in place, HOA boards sometimes push back on solar applications. Providing detailed, professional plans from the start, being clear about your legal rights under N.C. General Statute 22B-20, and approaching the process with clear communication tends to resolve most objections.
Zoning Complications Ground-mounted systems and installations in historic districts sometimes face extra scrutiny. Consulting with local zoning authorities early in the process helps identify any potential issues before the design is finalized.
Why Compliance Matters
Some homeowners wonder whether skipping permits is worth the trouble. It is not. Here is why compliance is non-negotiable.
Safety Permits and inspections exist to protect you, your home, and the electrical grid. A properly permitted and inspected system has been verified to be free from electrical hazards, structural risks, and fire concerns. An uninspected system has not.
Legal and Financial Risk Installing solar without the required permits can result in fines, forced removal of the system, and complications when selling your home. Title companies and buyers routinely check for unpermitted work.
Incentive Eligibility Many rebates and utility incentive programs, including Duke Energy’s PowerPair program, require proof of permit compliance before issuing payments. Without permits, you may lose access to thousands of dollars in rebates. For information on what is available, see 8MSolar’s guide to residential solar tax credits and rebates.
Home Sale Buyers and their lenders often require documentation that a solar system was permitted and inspected. A fully permitted system is an asset at resale; an unpermitted one is a liability.
The North Carolina Advantage
North Carolina has built a supportive environment for residential solar. Key protections and programs include:
- Legal right to install solar under N.C. General Statute 22B-20, even in HOA communities
- 80% property tax exemption on the appraised value solar adds to your home
- Duke Energy PowerPair rebates of up to $9,000 for solar and battery systems
- REPS mandate that creates a stable market for solar energy
- Net metering transition that, while changing, still provides compensation for excess solar production
North Carolina also ranks among the top ten states for solar capacity installed, with a strong network of experienced installers, knowledgeable building departments, and utility programs built around solar adoption.
Future Trends in Solar Permitting
The permitting landscape continues to improve. Here are the developments most worth watching.
Online Permitting More states and municipalities are adopting digital permitting platforms that allow for faster application submission, real-time status tracking, and electronic plan review. California and New York are leading examples of what streamlined digital permitting can look like.
Standardized Permits There is growing momentum behind standardizing permit requirements across jurisdictions. Uniform codes reduce confusion, cut administrative overhead, and make the process more predictable for installers and homeowners alike.
Interconnection Modernization As distributed solar continues to grow, utilities are modernizing their interconnection processes to handle higher volumes more efficiently. This benefits homeowners by reducing the wait time between system installation and Permission to Operate.
State Incentive Programs With the federal residential tax credit now expired, state and utility incentive programs are likely to become more prominent. Homeowners should expect continued activity at the state level as legislatures and utilities respond to the policy shift.
Frequently Asked Questions
Do I need a permit to install solar panels? Yes, in virtually every jurisdiction. At minimum, you will need a building permit and an electrical permit. Most grid-tied systems also require utility interconnection approval. Your installer handles all of this on your behalf.
How long does the permitting process take? The permit review phase typically takes one to four weeks depending on your municipality. The full process from contract signing to Permission to Operate generally runs six to twelve weeks.
Can my HOA stop me from installing solar in North Carolina? No. Under North Carolina General Statute 22B-20, HOAs cannot prohibit or effectively prohibit solar installations. They may impose reasonable requirements on placement, but they cannot require placement that significantly reduces system output or drives up costs. The NC Supreme Court confirmed this in 2022.
Is the federal solar tax credit still available? Not for homeowners who purchase or finance their own system. The 30% Section 25D residential credit expired on December 31, 2025 with no phase-down. If you install and own your solar system in 2026, there is no federal tax credit available to you.
If you use a solar lease or PPA, the company that owns the panels may be able to claim the commercial Section 48E credit, provided construction begins before July 4, 2026 and the system is placed in service by December 31, 2027. Homeowners cannot claim this credit themselves. Whether the provider passes any of those savings to you through lower payments depends on the specific contract. Always consult a tax professional for guidance on your individual situation.
What financial incentives are still available in North Carolina in 2026? North Carolina homeowners can still benefit from Duke Energy’s PowerPair solar and battery rebates, the state’s 80% property tax exemption on solar-added home value, and compensation for excess solar generation under the updated net metering and interconnection policies.
What happens if I install solar without a permit? You risk fines, legal liability, forced removal of the system, and loss of eligibility for utility incentives and rebates. Unpermitted solar work can also create complications when selling your home.
Does solar increase my property taxes in North Carolina? No. North Carolina provides an 80% property tax exemption on the appraised value that a solar system adds to your home, so going solar does not meaningfully increase your property tax bill.
What is net metering and is it changing in North Carolina? Net metering allows you to send excess solar electricity back to the grid in exchange for credits on your bill. In North Carolina, traditional net metering is being phased out. Existing systems are grandfathered under the old rules through December 31, 2026. New installations are subject to updated compensation structures that vary by utility. Learn more at 8MSolar’s net metering guide.
