Yes. The Town's iWorq Citizen Portal explicitly lists 'Solar' as its own selectable work type within the combined Solar/Electrical/Gas/Plumbing permit application. However, no fixed dollar fee for solar is published anywhere — like every other Thatcher permit type, the fee is set by a Town Council resolution that is not published online. Arizona's statewide A.R.S. § 9-468 independently caps whatever fee is actually charged at the Town's actual cost of issuing the permit.
