The exemption is available for properties installed on or after January 1, 2014, and the nameplate capacity cannot exceed the load for the location where the system is installed. Before October 2014, municipalities can choose to offer such an exemption (See a Local Option Property Tax Exemption). Commercial and industrial systems installed after Janury 1, 2010 and located in a "distressed municipality" with a population between 125,000 and 135,000 are eligible for the property tax exemption beginning in October 2013.
