Madison - Equipment Certification

Although the state of Wisconsin does not have any state laws specific to contracting and installing renewable energy systems, the City of Madison has issued rules for contractor licensing and equipment standards. In the city’s Heating, Ventilating and Air Conditioning Code is a requirement for a Class A-4 license for "a person desiring to enter into the business of installing, altering or repairing active solar heating equipment." In addition, equipment standards for solar thermal equipment cover subjects such as orientation of the collector, shading of solar collectors, mounting and roof support, material corrosion, sensors, piping and insulation, fluids, storage, monitoring and manuals.
