"Setbacks. (1) Architectural features needed for the operation of active or passive solar energy systems, including but not limited to canopies, eaves, overhangs, detached solar collectors, reflectors, piping and movable insulation may be permitted to extend up to 10 feet into required yard areas when these devices are a functional component of the space heating or domestic hot water system of the principal building lot. (2) The rear or side yard setbacks required may be reduced to zero in order to allow the siting of solar energy systems; provided, that: (a) No portion of the structure or architectural features project over the property lines. (b) Exposure protection between structures is provided according to the specifications of all applicable fire and safety regulations guaranteeing emergency access, light and ventilation. (c) The placement of all structures, building materials, and finished wall construction along the lot line does not interfere with traffic along adjacent or intersecting rights-of-way or with the site distance at intersections. (d) No other design can be shown to meet the requirements of this chapter and provide the same solar energy utilization. (e) Existing solar energy systems will not be substantially impaired by shadowing more than 10% of the collector area between 9:00 a.m. and 3:00 p.m. on a clear winter solstice (December 21) day."
