City of Dubuque - Solar Thermal Licensing Requirement

If you want to install a solar thermal system (for water or space heating) in Dubuque, your installer must hold a Solar Thermal License from the city—this applies only to solar thermal, not solar panels. Your contractor can obtain this license either through NABCEP Solar Thermal Certification or by completing Northeast Iowa Community College's Solar Thermal training program. Before installation begins, your contractor must also obtain a permit from the city's Inspection & Construction Services Division.

To work on solar thermal projects in Dubuque, you must obtain a Solar Thermal License by either earning NABCEP Solar Thermal Certification or completing Northeast Iowa Community College's Solar Thermal training. Once licensed, you must apply for a permit for each project, submitting detailed system drawings, site plans showing collector placement and nearby shading obstructions, and project details to the city's Inspection & Construction Services Division. Note that this requirement applies only to solar thermal systems; solar photovoltaic work in Iowa requires only state-level electrical contractor or journeyman licensing.

This local licensing requirement ensures solar thermal installers meet minimum technical standards through either national certification (NABCEP) or the regional community college training program. The city's Inspection & Construction Services Division administers permitting, requiring applicants to submit detailed technical documentation including piping layouts, equipment specifications, and site plans with shadow analysis. The program targets residential and commercial solar thermal projects within Dubuque city limits and applies only to thermal systems, not PV installations.
