Authorization for this chapter is contained in Wyoming Statutes, 1977, sections 34-22-101 through 34-22-106.

§ 20-3 Purpose and intent of chapter.

The purpose of this chapter is to protect the health, safety and general welfare of the City by encouraging the use of solar energy systems. It is the intent of this chapter to provide a means of protection for the use of solar collectors without causing undue hardships on the rights of adjacent property owners and to establish solar collectors as a permitted use in all zoning or land use districts.

§ 20-4 Definitions.

For the purposes of this chapter, the following words and phrases shall have the meanings respectively ascribed to them by this section:
SOLAR COLLECTOR
One of the following, which is capable of collecting, storing or transmitting at least twenty-five thousand 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 or all 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;

F. 
A massive structural element designed to collect solar energy and transmit it to internal spaces for heating; or
G. 
Other devices or combination of devices that rely upon sunshine as an energy source.
SOLAR RIGHT
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 chapter.
WINTER SOLSTICE DAY
The solstice on or about December 21 which marks the beginning of winter in the northern hemisphere and the time when the sun reaches its southernmost point.

§ 20-5 Shading of collectors prohibited; location of collectors.

A. 
Except as otherwise provided by this chapter, it is unlawful for any person to erect a building or other structure so as to, or to allow a tree, shrub or other vegetation to, cast a shadow upon a solar collector which is greater than the shadow cast by a hypothetical ten foot high wall located along the property lines, between the hours of 9:00 A.M. and 3: 00 P.M. Mountain Standard Time, on the winter solstice day.
B. 
Solar collectors shall be located on the solar user's property, so as not to unreasonably or unnecessarily restrict the uses of neighboring property.

§ 20-6 Certain structures or vegetation exempt from section 20-5.

Structures or vegetation which existed prior to the time of installation of the solar energy collection system or the effective date of this chapter shall not be subject to the requirements of section 16-6.

§ 20-7 Variances.

Any person desiring to erect any structure, increase the height of any structure, permit the growth of any tree or other vegetation or otherwise use his property, not in conformance with this chapter, may apply for a variance from the planning and zoning commission. A variance shall not be approved by the commission unless it finds that the literal enforcement or application of this chapter would result in unnecessary hardship.

The building inspector or other administrative official shall certify the right and its beneficial use within two years.
D. 
Existing solar collector users shall apply for permits within five years after the date this chapter is passed.
E. 
A solar right which is not applied to a beneficial use for a period of five years or more shall be deemed abandoned and without priority.
