The District of Columbia Council created a personal property tax exemption for solar energy systems and cogeneration systems within the District by enacting B19-0749 in December of 2012.

Eligible solar systems Solar energy is defined by D.C. Code § 34-1431 to mean "radiant energy, direct, diffuse, or reflected, received from the sun at wavelengths suitable for conversion into thermal, chemical, or electrical energy, that is collected, generated, or stored for use at a later time". This seemingly broad definition can include solar photovoltaics (PV), solar thermal, or any other energy technology that uses solar energy.

Eligible cogeneration systems are defined as those which "produce both electric energy and steam or forms of useful energy which are used for industrial, commercial, heating or cooling purposes".
