(a) As used in this act:
(i) "Solar collector," except as provided in subsection (b) of this section, is one (1) of the following which is capable of collecting, storing or transmitting at least twenty-five thousand (25,000) BTU's on a clear winter solstice day:
(A) A wall, clerestory or skylight window designed to transmit solar energy into a structure for heating purposes;
(B) A greenhouse attached to another structure and designed to provide part of the heating load for the structure to which it is attached;
(C) A trombe wall, "drum wall" or other wall or roof structural element designed to collect and transmit solar energy into a structure;
(D) A photovoltaic collector designed to convert solar energy into electric energy;
(E) A plate-type collector designed to use solar energy to heat air, water or other fluids for use in hot water or space heating or for other applications; or
(F) A massive structural element designed to collect solar energy and transmit it to internal spaces for heating.
(ii) "Solar right" is a property right to an unobstructed line-of-sight path from a solar collector to the sun which permits radiation from the sun to impinge directly on the solar collector. The extent of the solar right shall be described by that illumination provided by the path of the sun on the winter solstice day which is put to a beneficial use or otherwise limited by this act;

(iv) "Local government" means a city, town or county;
(v) "This act" means W.S. 34-22-101 through 34-22-106.
(b) For purposes of this act, "solar collector" shall not include a solar collector that is part of a facility that:
(i) Has a rated power capacity of more than five hundred (500) kilowatts; or
(ii) Would result in a surface disturbance equal to or greater than one hundred (100) acres.
