Renewable Energy Property Tax Exemption

Summary

Systems that generate energy using wind, hydropower, geothermal, and solar energy heating or cooling systems are exempt from property tax.* Systems using solar power devices—including solar thermal, photovoltaic (PV), and other solar energy—are exempt from property tax only if they were installed after December 31, 2011. 

For most eligible renewable energy systems, the assessed value of the system is exempt from property tax. One exception is solar energy heating or cooling systems which are exempt from property tax the amount equal to the out-of-pocket expenditures for the components and labor associated with the system. 

The property tax exemption is allowed every year that a qualifying system functions. The property tax exemption applies to both real property and mobile homes equipped with renewable energy systems and may only be claimed by property owners. Public utilities and other electricity retailers (excluding net metered customers) may not claim a property tax exemption for wind or solar power devices.
