Are renewable energy systems exempt from property tax in Wisconsin?

In Wisconsin, any value added by a solar or wind energy system is exempted from general property taxes. A solar energy system is defined as equipment which directly converts and then transfers or stores solar energy into usable forms of thermal or electrical energy, but does not include equipment or components that would be present as part of a conventional energy system or a system that operates without mechanical means. A wind energy system is defined as equipment which converts and then transfers or stores energy from the wind into usable forms of energy, but does not include equipment or components that would be present as part of a conventional energy system.
