Summary
Appleton requires an electrical permit before any solar photovoltaic installation begins, issued by the Inspection Department under the electrical code. A licensed electrical contractor must do the work unless the homeowner is a Wisconsin-licensed electrician installing a system on the single-family home they own and occupy.
As allowed under Wis. Stats. §101.862(4)(a), a residential property owner may perform electrical work without a license in a dwelling which the individual owns and occupies as long as the work is being conducted in a single-family dwelling. In the case of installing, replacing, or repairing service equipment, solar photovoltaic installations, or electrical work performed on a residential property which is not a single-family owner-occupied dwelling, the electrical work shall be performed by a licensed electrical contractor, meeting all the requirements of SPS 305.41 as amended from time to time. A Wisconsin licensed electrician is allowed to install, replace, or repair the service equipment and install, replace, or repair a solar photovoltaic system on a single-family dwelling which is owned and occupied by said electrician and an electrical contractor license is not required to perform such work. The owner of the property must procure a permit prior to starting any electrical work. The property owner may not procure a permit on behalf of an electrical contractor or another individual.

Full Breakdown
The Inspection Department issues electrical permits for photovoltaic installations under City Code Section 4-416, and the application must be made on forms furnished by the Director describing the nature of the work; Section 4-416(2) additionally requires PV systems to meet the requirements listed in the city's separate "Photovoltaic System Permit Requirements" handout. No electrical work, including a PV installation, may start before the permit is issued. 41 must install, replace or repair a solar photovoltaic system on any property that is not a single-family, owner-occupied dwelling.
The one carve-out is a Wisconsin-licensed electrician who owns and occupies the single-family home receiving the system; that electrician may wire their own PV system without holding a separate electrical contractor license, but must still personally procure the permit and cannot obtain one on behalf of a contractor or any other individual. The same owner exemption extends to accessory structures on the same parcel. Section 4-418(f) sets a separate PV system permit fee, kept on file in the Office of the City Clerk rather than printed in the code itself, and Section 4-418(g) triples the standard permit fee for anyone who starts electrical work, including a solar installation, before the permit is obtained. Failing to notify the electrical inspector before concealing wiring nullifies the residential owner exemption under Section 4-392 outright, per the cross-reference in Section 4-350.
Violations & Fines
Beginning electrical work, including a solar PV installation, without first obtaining the permit triples the standard permit fee once the permit is later obtained, under Section 4-418(g); that penalty sits on top of any other violation penalty under the electrical article. Where the electrical inspector condemns all or part of an installation, Section 4-350 gives the owner five days to file a written petition for review with the chairman of the Board of Building Inspection. Concealing wiring before inspection voids the owner's licensing exemption under Section 4-392.
