Wisconsin Solar License Requirements (2026)

Wisconsin does not list a stand-alone solar-PV contractor credential. Installing the electrical wiring for a PV project is electrical work: DSPS says a business that offers to install, repair, or maintain electrical wiring must hold an Electrical Contractor license unless a statutory exception applies, and the work must be performed by appropriately licensed or registered people. A licensed Master Electrician or Registered Master Electrician may be responsible for the installation; the exact credential and supervision arrangement must fit the project. This guide addresses PV electrical work. Confirm the separate trade and permit rules for solar-thermal, plumbing, structural, utility-interconnection, and local work before contracting.

Regulatory Body

Wisconsin Department of Safety and Professional Services (DSPS) administers and enforces this credential under the authority of Wis. Stat. Chapter 101 (Department of Safety and Professional Services); Wis. Admin. Code SPS chapters covering electrical, plumbing, HVAC, and dwelling contractors. DSPS administers credentialing for construction trades in Wisconsin, adopts and enforces the Wisconsin Uniform Dwelling Code, Wisconsin Electrical Code, and Wisconsin Plumbing Code, and conducts disciplinary proceedings against credential holders.

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. DSPS applications are made through LicensE. The current Electrical Contractor application identifies the applicant as the business owner, a partner, or the corporation’s chair or chief executive officer; use the current application for identity and eligibility details.

Good moral character

DSPS provides a Trades Convictions and Pending Charges form when applicable; do not assume an automatic disqualification.

Background investigation

Use the current DSPS application and any requested conviction documentation. No universal solar-specific background-check rule was identified.

Experience and Education

Eligibility here is not measured in years of experience but by There is no separate solar experience pathway. For the full Master Electrician examination, DSPS accepts one of several routes: 12 months as a licensed Journeyman Electrician; 10,000 wiring hours over at least 60 months; at least 1,000 hours a year for seven years; or an accredited electrical-engineering bachelor’s or master’s degree., per the cited materials.

Accepted proof of experience or eligibility

• DSPS Master Electrician application information and experience form (Form 3107/3107T, if using an experience route)
• Copy of the Journeyman license or qualifying transcripts, as applicable
• Current DSPS Electrical Contractor application for the business

Education substitution

For the 10,000-hour or seven-year Master path, DSPS may credit full-time electrical-related schooling at 500 hours per semester, up to 3,000 hours and three years. An accredited electrical-engineering bachelor’s or master’s degree is also a separate Master-exam route.

Exam Requirements

Testing provider or authority: Wisconsin DSPS makes an eligible Master applicant available to test; DSPS publishes the examination information.. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

• Wisconsin Master Electrician examination — question count: confirm with the authority, timing: confirm with the authority, passing score 70%

Examination fee: DSPS calculates current application and examination fees in LicensE; the current Master examination page confirms an open-book examination and a 70% passing score but does not publish the former fixed PSI price.

Retake policy: If an applicant fails, DSPS instructs the applicant to return to LicensE and pay another examination fee. Confirm the current scheduling and retest rules there.

Insurance and Bonds

This credential carries no state-level surety bond requirement under the cited sources. Individual jobs may still trigger a permit or public-works bond, which should be verified before bidding.

General liability

The current DSPS Electrical Contractor application does not state a statewide general-liability minimum. Do not substitute an industry insurance target for a DSPS requirement; local, owner, lender, utility, or contract requirements can still apply.

Workers' compensation

The Electrical Contractor applicant attests to compliance with Wis. Stat. ch. 102. Wisconsin generally requires coverage when an employer has three or more employees, or when one or more employees have been paid combined gross wages of $500 or more in a Wisconsin calendar quarter; confirm status with DWD.

Additional financial requirements

No financial-statement requirement was identified in the current DSPS Electrical Contractor application information.

Fee Schedule

Renewal and Continuing Education

Renewal of the Wisconsin Solar PV — Electrical Contractor and Electrician Credentials comes due every 4 years. As cited, the renewal fee stands at $200. The published schedule lists a June 30 renewal date for both Electrical Contractor and Master Electrician credentials.

Continuing education: A licensed Master Electrician needs at least 24 hours of acceptable continuing education before renewal. The DSPS Electrical Contractor renewal schedule lists the same four-year cycle and $200 fee; confirm any current CE or role-specific requirement in LicensE.

Reciprocity

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

This is an individual Master Electrician route, not solar-contractor reciprocity. No Minnesota reciprocity claim was supported by the current DSPS Master application reviewed.

Solar Licensing in Neighboring States

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

• Illinois Solar License Requirements — Illinois Commerce Commission Distributed Generation Installer Certification (Solar PV)
• Iowa Solar License Requirements — Iowa Electrical Contractor License for Solar PV Work
• Michigan Solar License Requirements — Michigan Electrical Contractor License with Master Electrician
• Minnesota Solar License Requirements — Minnesota Residential Building Contractor or Residential Remodeler License (Residential Solar PV Contracting)

Step-by-Step Application Roadmap

1. Define the project scope. Identify PV electrical wiring, any dwelling work, structural work, utility interconnection, and non-electrical work before choosing credentials.
2. Obtain the business credential. Before offering to install, repair, or maintain electrical wiring, obtain the DSPS Electrical Contractor license unless a statutory exception applies.
3. Staff the electrical work correctly. Use appropriately licensed or registered electrical workers and the supervision arrangement required by DSPS for the actual credential level.
4. Use the applicable Master path when responsibility requires it. A full Master applicant must qualify by one of DSPS’s experience or degree routes and pass the open-book exam at 70%.
5. Obtain permits before regulated work begins. For electrical installations requiring a Uniform Dwelling Code permit, DSPS says a responsible Master or Electrical Contractor may not begin electrical installation until the permit is issued. The permit is issued by the municipality or an authorized UDC inspection agency.
6. Complete local and utility approvals. Confirm the authority having jurisdiction’s inspection process and the serving utility’s interconnection requirements; neither is replaced by an electrical credential.

Application Checklist

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

• Define the PV and non-electrical scope
• Apply for DSPS Electrical Contractor licensing if the business will offer covered electrical work
• Use appropriately licensed or registered electrical workers
• Document a DSPS Master path if the responsible role requires it
• Apply through LicensE and confirm current calculated fees
• Obtain the local/UDC permit before electrical work that requires it
• Complete local inspection and serving-utility interconnection requirements

Common Filing Mistakes

Working from the cited board instructions, here are the snags most likely to trip up a Wisconsin Solar filing.

Treating PV as an unlicensed specialty

The electrical-wiring portion is regulated under Wisconsin’s electrical framework; do not rely on a nonexistent solar-only credential.

Assuming a Master is the only path for every business

The current Electrical Contractor material requires the business license and appropriately credentialed people. Match the supervisory/responsible credential to the project rather than repeating a blanket qualifier claim.

Using obsolete fixed exam fees or metrics

The current DSPS process calculates application and examination fees in LicensE; the Master page only substantiates the open-book format and 70% passing score.

Starting permit work early

Where a UDC electrical permit is required, DSPS says the responsible Master or Electrical Contractor may not start installation before it is issued.

Frequently Asked Questions

Does Wisconsin have a separate solar license?

DSPS does not list a stand-alone solar-PV credential. PV electrical wiring is subject to the state electrical-credential framework and applicable permits.

Must every solar business employ a Master Electrician?

Do not rely on that blanket claim. The business needs an Electrical Contractor license for covered electrical business activity, and DSPS requires appropriately licensed or registered people for the work. A Master or Registered Master may be responsible for an installation; confirm the correct arrangement for the scope.

How can I qualify for the full Master Electrician examination?

DSPS recognizes 12 months as a licensed Journeyman, specified 10,000-hour/60-month or seven-year experience routes, or an accredited electrical-engineering bachelor’s or master’s degree.

Does the Master examination have a published question count or former PSI fee?

The current DSPS page confirms an open-book exam and 70% passing score. It does not publish the former fixed PSI metrics; DSPS now calculates application and exam fees in LicensE.

Is there Iowa reciprocity?

A current Iowa Master A Electrician who obtained the credential through a state exam and has held it continuously for at least a year may use DSPS’s no-Wisconsin-exam Master route. It is not solar-contractor reciprocity.
