Illinois offers a special assessment of solar energy systems for property-tax purposes. For property owners who register with a chief county assessment officer, solar energy equipment is valued at no more than a conventional energy system. Eligible equipment includes both active and passive solar-energy systems. The exemption is not valid for equipment that is equally usable in a conventional energy system or for components that serve non-solar energy generating (e.g., structural, aesthetic, insulating, etc.) purposes.

Application for Solar Assessment
Those who wish to have their solar energy property valued in this fashion must file the State of Illinois PTAX-330 property tax form with their local county assessor's office. Forms are available online and through each Illinois county assessor's office.
