The Interstate Renewable Energy Council (IREC), Latham, N.Y., supported by the US Department of Energy (DOE), has created a Solar Licensing Database as a resource for policy makers, practitioners, consumers and anyone else looking for solar licensing information in the U.S. The state-by-state information offers a handy comparison for reviewing the different approaches across state lines, and identifies various practices for regulating the solar installation industry.
As you will see in this free database, many states require that licensed electricians handle photovoltaic installations.
