Illinois Solar Contractor Requirements (2026)

Regulatory Body

This license is issued and enforced by Illinois Commerce Commission (ICC) pursuant to 220 ILCS 5/16-128A; 83 Ill. Adm. Code Part 468. The ICC certifies distributed-generation installer entities. Municipal authorities retain their own electrical, contractor, permit, and bonding requirements.

Eligibility Requirements

This guide does not establish a minimum applicant age; confirm any age requirement with the issuing authority. Check the current application for identification and tax-number requirements. The applicant is the installing entity. The ICC rules require that entity to be licensed to do business in Illinois; use the current ICC application materials for entity and designated-agent details.

Good moral character

The certificate holder must comply with the Act and Part 468. The Commission may suspend, revoke, or fine a certificate holder for noncompliance.

Background investigation

Part 468 does not state a statewide solar-PV criminal-background or fingerprint requirement. A municipality may have its own application disclosures.

Experience and Education

There is no published year count for this credential in the cited sources. What actually controls eligibility is A qualified person must either have performed five installations of the same distributed-generation technology, or complete a listed hands-on/laboratory training route and receive its certification. Listed routes include a U.S. Department of Labor journeyman-electrician apprenticeship, NABCEP, UL, or ETA DG technician certification, or an associate degree from an ICCB-approved community college..

Accepted proof of experience or eligibility

ICC application documentation showing a qualified person
Training certificate or affidavit documenting five installations of the same DG technology
Current entity authorization to do business in Illinois

Education substitution

The Part 468 training and certification routes are alternatives to the five-installation route; NABCEP is one option, not a universal prerequisite.

Exam Requirements

This credential carries no state-administered written exam under the cited sources. What governs instead is: No Illinois solar-PV trade examination is specified for the ICC DG Installer Certificate

Examination fee: $50 ICC certificate application fee. A chosen training or third-party certification route can have separate provider fees.

Retake policy: Not applicable to the ICC certificate; follow the selected training or certification provider’s rules.

Insurance and Bonds

See the official sources for this guide

The cited state source set does not require a contractor license surety bond for this credential. Contractors should still confirm project-specific bond, permit-bond, or public-works bond requirements before bidding.

General liability

Part 468 does not state a fixed ICC commercial-general-liability minimum. The certificate holder must comply with applicable municipal licensing and bonding requirements, which can include insurance requirements.

Workers' compensation

Maintain workers’ compensation coverage when required by Illinois law for the business and its employees.

Additional financial requirements

No fixed statewide contractor bond or financial-statement requirement is stated in Part 468 for this certificate.

Fee Schedule

Fee	Amount
Application (non-refundable)	$50
Initial license	No separate state fee
Renewal (every year)	No separate state fee

See the official sources for this guide

Renewal and Continuing Education

Renewal of the Illinois Commerce Commission Distributed Generation Installer Certification (Solar PV) comes due every year. The cited state source set does not list a separate statewide renewal fee. Annual recertification information is due April 1. The current Part 468 fee section lists a $50 application fee but no separate annual recertification charge.

Continuing education: Part 468 does not state a statewide continuing-education hour requirement for annual ICC recertification. Maintain the facts and documentation required by the current recertification form.

Reciprocity

See the official sources for this guide

The NASCLA Accredited Examination is not accepted by Illinois for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

Part 468 uses its own qualified-person routes and does not identify a state-to-state reciprocity program. An out-of-state installer should apply directly and meet the Illinois entity, qualified-person, and local requirements.

Solar Licensing in Neighboring States

Contractors working near a state line, or weighing where to qualify first, should compare Illinois's requirements against the bordering jurisdictions before committing to an application:

Indiana Solar License Requirements — Indiana Solar — No State Solar Contractor License (Local Approval Path)
Iowa Solar License Requirements — Iowa Electrical Contractor License for Solar PV Work
Kentucky Solar License Requirements — Kentucky Solar Installation Requirements — Electrical Contractor and Local Permits
Missouri Solar License Requirements — Missouri Solar Contractor Requirements — Statewide Electrical and Local Permit Path
Wisconsin Solar License Requirements — Wisconsin Solar PV — Electrical Contractor and Electrician Credentials

Step-by-Step Application Roadmap

Identify the actual installer entity. The ICC certificate is held by the entity that installs the DG facility, except for the statutory self-installer exception.
Choose a qualified-person route. Document five same-technology installations or use one of the Part 468 hands-on training and certification routes.
Ensure the entity may do business in Illinois. Part 468 requires the certificate holder to be licensed to do business in Illinois.
Apply to the ICC. File the Distributed Generation Installer Certificate application and the $50 application fee with the required qualified-person documentation.
Meet local electrical and building requirements. Obtain the electrical/contractor credentials, permits, inspections, and any bonding required by the authority having jurisdiction. Illinois does not make the ICC certificate a substitute for those local approvals.
Complete utility interconnection requirements. Use the serving utility’s current interconnection process; ICC certification is not the utility interconnection approval.
Use the correct Illinois Shines role when applicable. Illinois Shines payments and REC contracts go to Approved Vendors. A DG installer working on program projects is registered as the applicable Approved Vendor’s Designee and must have an active ICC certificate.
Recertify annually. File the annual ICC recertification information by April 1 and keep installation documentation for at least three calendar years after the year created.

Application Checklist

The most critical documents or confirmations the applicant should have in hand before filing with ICC:

Installer entity authorized to do business in Illinois
Qualified person using a Part 468 route
ICC DG Installer Certificate application and $50 fee
Municipal electrical/contractor credentials and bonding where required
Project-specific building and electrical permits and inspections
Serving-utility interconnection approval
Illinois Shines Approved Vendor or Designee setup when participating
Annual ICC recertification by April 1

Common Filing Mistakes

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a Illinois Solar application.

Calling the ICC certificate an electrical-contractor license

It is a statewide DG-installer certification. It does not replace the municipality’s electrical, contractor, permit, inspection, or bonding requirements.

Treating NABCEP as the only route

Part 468 provides several alternative qualified-person routes. Match the documentation to the same DG technology being installed.

Missing the annual April 1 filing

Certificate holders must make the annual recertification filing by April 1; a filing more than 30 days late can trigger enforcement.

Skipping installation records

Keep the Part 468 installation documentation for at least three calendar years after the year it was created.

Using the wrong Illinois Shines role

The Approved Vendor, not every installer, receives program payments and REC contracts. Confirm whether the installer is properly registered as that vendor’s Designee.

Frequently Asked Questions

Does Illinois have a state solar contractor license?

Illinois does not issue a general solar-contractor license. For a non-self installer of a distributed-generation facility, the installer entity must hold an ICC Distributed Generation Installer Certificate before installation. Local electrical, contractor, and permit rules still apply.

Is NABCEP required for the ICC certificate?

No. NABCEP certification is one listed qualified-person route. Part 468 also allows five documented same-technology installations, certain DOL apprenticeship and UL or ETA certifications, or a qualifying ICCB-approved associate degree.

What does the ICC application cost?

Part 468 lists a $50 application fee. It does not list a separate annual recertification charge; training, third-party certification, local approval, and project costs are separate.

When is ICC recertification due?

The certificate holder files the annual recertification information by April 1. A filing more than 30 days late can lead to suspension or other Commission action.

Do I need to be an Illinois Shines Approved Vendor?

Only Approved Vendors receive Illinois Shines REC contracts and payments. An installing company may instead work as an Approved Vendor’s registered Designee; for DG projects, an Installer Designee needs an active ICC DG Installer Certificate.
