To work as a contractor in Florida in the solar water heating and/or the photovoltaic (PV) installation industry requires licensing by the Florida Construction Industry Licensing Board or the Electrical Contractors Licensing Board of the Florida Department of Business and Professional Regulation.  Under these two boards, the following licenses may be received (all of the following licenses require registration with the board, payment of fees and the passing of an examination):

1. Solar Contractor (CV) is an individual whose scope of work covers residential and commercial solar water heating, solar pool heating and photovoltaic (solar electric, or PV) systems. The CV license holder is exempt from subcontracting certain roofing, plumbing and electrical work on residential installations.
   
   
2. Residential Solar Water Heating Specialty Contractor (CW) is an individual whose scope of work is limited to solar water heating and solar pool heating systems on residences only. The CW license holder is not authorized to install PV systems and is not authorized to install solar water heating or pool heating systems on commercial buildings. Since the CW license does not have these tasks included in its scope of work, a CW license holder may not subcontract the work to an authorized license holder (such as an electrical contractor or CV solar contractor).
   
   
3. Plumbing Contractor (PF) is an individual who is also authorized to install solar water heaters and pool heaters, but may be required to subcontract roofing and electrical work if the local building department so requires. Plumbing contractors are not authorized to install PV systems.
   
   
4. Electrical Contractor (EC) is an individual who may install, maintain, repair, or alter any electrical service (including PV systems). Electrical contractors may be required to subcontract roofing work if the local building department so requires.
   
   
5. Solar pool heaters may be installed by a Certified Swimming Pool Contractors (CP, RP).
   
   
6. Local Licensing - Several local (city or county) licensing jurisdictions have established a solar contractor certificate of competency that is usually designated as an RX license. These are limited to the installation of solar water or pool heaters only within the jurisdiction that has granted the license, and generally will not be authorized to install PV systems.
