Solar Panel Permit Requirements in Arkansas (2025)

Yes, you need permits. Residential and commercial solar PV installations in Arkansas require a building permit and an electrical permit from the local city or county, plus separate utility interconnection approval. Plan for 1 to 4 weeks for local permits and an additional 30 to 90 days for the utility to issue Permission to Operate.

Quick Answer: Do You Need a Permit for Solar Panels in Arkansas?

Yes. Arkansas law provides no exemption for solar panels that bypasses local permitting. You will need approvals from both your local government and your electric utility.

Local permits (city or county): A building permit covers structural work, roof penetrations, and racking. An electrical permit covers wiring, the inverter, and the connection to the main service panel. Both are issued by the local building department.

Utility interconnection approval: This approval is separate from local permits and is governed statewide by the Arkansas Public Service Commission (APSC) under the Arkansas Renewable Energy Development Act of 2001 (Ark. Code Ann. § 23-18-601 et seq.), as amended by Act 464 (2019). Your utility must approve the interconnection before you can legally operate the system and receive net-metering credits.

Permission to Operate (PTO): After local inspections pass and the utility completes its review, the utility issues a PTO. The system cannot be energized until you receive this authorization.

Local permit approval typically takes one to four weeks. The utility interconnection review adds another 30 to 90 days, depending on the utility. Arkansas does not have a single statewide solar permit form; requirements, fees, and submission methods vary by municipality and county.

State Law and Regulatory Framework Governing Solar Permits

Arkansas Renewable Energy Development Act

The primary statute governing solar interconnection is Ark. Code Ann. § 23-18-601 et seq., the Arkansas Renewable Energy Development Act of 2001. Act 464 (SB 145 of 2019) amended definitions within this act and clarified the APSC's authority over net-metering and interconnection standards for utilities in Arkansas. The APSC sets the rules that investor-owned utilities and most electric cooperatives must follow for customer-sited generation.

APSC Role

The APSC administers net-metering rules through its General Service Rules and utility-specific tariffs. When you submit an interconnection application, your utility follows APSC-approved procedures. The APSC has jurisdiction to hear complaints if a utility denies or delays an application without cause.

Electrical Code and Fire Code

Arkansas adopts the National Electrical Code (NEC) at the state level, which forms the basis for local electrical permit requirements. NEC Article 690 specifically governs solar photovoltaic systems. Consult the Arkansas State Building Services division to confirm the currently adopted NEC edition, as local jurisdictions may be on different cycles.

Contractor Licensing

The Arkansas Code Enforcement Licensing Board (CELB) licenses electrical contractors under Ark. Code Ann. § 17-25-101 et seq. In most Arkansas jurisdictions, a CELB-licensed electrical contractor must obtain the electrical permit for a solar installation.

SB 493 (2025): No Change

SB 493 (2025) proposed consolidating several trade-related licensing boards into the CELB. The bill died in a Senate Committee at Sine Die adjournment in May 2025. The licensing structure under Ark. Code Ann. § 17-25-101 et seq. is unchanged.

Local Jurisdiction Authority

Arkansas law grants cities and counties the authority to administer their own building codes. This autonomy results in different permit fees, review times, and submission methods across the state.

Types of Permits Required for a Solar Installation in Arkansas

Building Permit

A building permit is required for structural work, including roof penetrations, racking attachment, and conduit runs affecting the building envelope. It is issued by the city or county building department. The application typically requires a site plan, a roof plan, and sometimes structural calculations signed by an engineer.

Electrical Permit

An electrical permit is required for all wiring, inverter installation, disconnects, and the connection to the main service panel. In most jurisdictions, this permit must be obtained by a CELB-licensed electrical contractor (Ark. Code Ann. § 17-25-101 et seq.). The application requires a single-line electrical diagram and equipment specification sheets. The installation must comply with the locally adopted edition of NEC Article 690.

Zoning or Land-Use Approval

Some municipalities require a separate zoning review or conditional use permit, especially for ground-mounted systems or installations in historic districts. Homeowners' associations may have their own separate approval processes. Check local ordinances before assuming a rooftop system is allowed by right.

Utility Interconnection Application

This application is submitted directly to your electric utility (e.g., Entergy Arkansas, SWEPCO, OG&E, or a local cooperative) under APSC rules. It is a parallel process to local permitting and includes a signed interconnection agreement and technical system documentation. The utility reviews the application for grid safety and reliability before granting approval.

Permission to Operate (PTO)

The utility issues PTO after its review is complete and local inspections have passed. A grid-tied solar system cannot be legally energized without PTO.

Who Can Pull Which Permit

In most Arkansas jurisdictions, homeowners can obtain a building permit for work on their primary residence. The electrical permit, however, typically requires a licensed electrical contractor. Confirm requirements with your local building department.

Permit Fees, Timelines, and Requirements by Jurisdiction

Fees are based on publicly available schedules and are subject to change. Verify all information directly with the relevant building department before submitting an application.

Arkansas building departments typically calculate permit fees based on a percentage of the declared project value or a flat fee per kilowatt of system capacity. Because rates change, it is critical to contact the department for the current fee schedule.

Some unincorporated counties may have minimal building code enforcement. Even in these areas, interconnection approval from the APSC-regulated utility is still required.

Under APSC standards, utilities should process interconnection applications for small residential systems (under 10 kW) within 30 days and larger systems within 90 days. Actual timelines vary by utility. Consult the APSC General Service Rules and your utility's tariff for specific requirements.

Step-by-Step Permit Application Process in Arkansas

Step 1: Hire a Licensed Electrical Contractor

Before signing a contract, verify the contractor holds a current license using the lookup tool on the Arkansas Code Enforcement Licensing Board (CELB) website. Licensing is governed by Ark. Code Ann. § 17-25-101 et seq.

Step 2: Prepare Your Application Documents

Your contractor should assemble the required documents, including:

• Site plan showing panel layout
• Roof plan with dimensions and attachment points
• Single-line electrical diagram
• Equipment specification sheets for the inverter and PV modules
• Structural calculations, if required by the jurisdiction
• Manufacturer installation instructions

Step 3: Submit Building and Electrical Permit Applications

Submit the application packet to your local city or county building department. Confirm whether the jurisdiction requires online or in-person submission.

Step 4: Await Plan Review

The building department reviews documents for compliance with the NEC and local building codes. Respond promptly to any correction requests from the reviewer to avoid delays.

Step 5: Receive Permit Approval and Post on Job Site

The approved permit must be posted visibly at the job site before work begins and must remain posted throughout the installation.

Step 6: Complete Installation and Schedule Inspections

Most jurisdictions require a rough electrical inspection before wiring is concealed and a final electrical inspection. Some may also require a structural inspection. The contractor coordinates scheduling with the building department.

Step 7: Pass All Inspections

After passing final inspections, the building department issues a final inspection card or other official sign-off. Retain copies of all inspection reports.

Step 8: Submit Utility Interconnection Application

The interconnection application should be submitted to your utility in parallel with the local permitting process, as soon as the system design is final. Each utility has its own forms and portal.

Step 9: Utility Review and Possible Site Visit

The utility reviews the application for grid compatibility. A site visit may be required before approval is granted.

Step 10: Receive Permission to Operate

Once the utility completes its review and confirms that local inspections are complete, it issues PTO. Only after receiving PTO can you legally energize the system and begin receiving net-metering credits under Ark. Code Ann. § 23-18-601 et seq.

Common Reasons for Rejection or Inspection Failure

• The single-line diagram does not match the installed equipment.
• Missing or incorrect labeling on disconnects and conduit (per NEC Article 690).
• Improper rapid shutdown system installation (NEC 690.12).
• Structural attachments do not match the approved plan.
• Incomplete documentation was submitted to the utility.

What Changed Recently: 2024–2025 Regulatory Updates

SB 493 (2025): Died, No Change to Licensing

SB 493 (2025), a bill to consolidate trade licensing boards, died in a Senate Committee in May 2025. The contractor licensing structure under Ark. Code Ann. § 17-25-101 et seq. remains in effect.

APSC Net Metering Proceedings

The APSC periodically reviews net metering compensation rates and interconnection rules. Changes made in APSC dockets can affect the financial return of a solar project. Use the APSC docket search tool at apscservices.info to check for open dockets related to net metering or distributed generation.

Federal Investment Tax Credit (ITC)

The federal ITC remains at 30% of the installed system cost under the Inflation Reduction Act (26 U.S.C. § 48(a)) through at least 2032. This federal incentive is not administered by the state. Consult a tax professional to confirm eligibility.

NEC Edition Currently Adopted in Arkansas

Consult Arkansas State Building Services to confirm which edition of the National Electrical Code is currently adopted statewide. Local jurisdictions may adopt different editions. Your installer must know which code cycle applies, as requirements for features like rapid shutdown (NEC 690.12) vary between editions.

SolarAPP+ Adoption

As of early 2025, no Arkansas municipality has publicly announced the adoption of the SolarAPP+ streamlined permit platform. Consult your local building department to ask about any available expedited or online solar permit options.
