Solar panel installations shall not obstruct any rooftop area access to which is required pursuant to FC 504.4, except that solar panel installations may obstruct the clear path required by FC 504.4.4 as follows: 1. if the installation is provided with a hinged mechanism or other device for which a certificate of approval has been issued that enables the installation to be safely swung, slid, lifted, collapsed or otherwise moved out of the clear path, and that is designed to allow for operation by one person, without the use of a tool; or 2. on any building with a rooftop width or depth of 25 feet (7620 mm) or less, where the design of a solar panel installation necessitates coverage of all or substantially all of the rooftop across the full width or length thereof, the commissioner may authorize permanent obstructions that encroach upon and thereby reduce the clear path width within such area when necessary to accommodate the presence of building features and building service equipment that constitute permanent obstructions, including attic ventilators, bulkheads, chimneys, hatches, plumbing ventilations pipes, scuttles, skylights, and roof-mounted heating, ventilation and air conditioning equipment. Such permanent obstructions may encroach upon and, for the distance of the obstruction, reduce the clear path width up to 2 feet (610 mm). Such permanent obstructions shall not reduce the width of clear path at any point to less than 4 feet (1219 mm) and shall not encroach upon the rooftop landing areas required by FC 504.4.3. 512.3 Pitched-roofed buildings and structures 100 feet or less in height. Solar panel installations shall be designed, installed, operated and maintained in accordance with this section on rooftops of buildings and structures 100 feet (30 480 mm) or less in height with a slope exceeding 20 degrees, except detached Group U buildings and structures. 512.3.1 Hip roofs. Solar panel installations shall provide a 3 foot (914 mm) wide clear access area along the ridge on each roof slope upon which solar panels are installed. 512.3.2 Ventilation. Solar panels shall not be installed closer than 3 feet (914 mm) to the ridge line. 512.4 Photovoltaic solar panel installations. Photovoltaic solar panel installations shall be designed, installed, operated and maintained in compliance with the requirements of this section. 512.4.1 Location of photovoltaic solar panel installations on pitched roofs. Direct current conduit, wiring systems, and raceways for photovoltaic circuits installed on pitched roofs subject to the requirements of FC 512.3 shall be located along hips and valleys, away from the ridge, and on outside walls, to maximize ventilation opportunities. Conduit runs between sub-arrays and to direct current combiner boxes shall be installed in a manner that minimizes the total amount of conduit on the roof by taking the shortest path from the array to the direct current combiner box, except as necessary to minimize the tripping hazard. The direct current combiner boxes shall be located such that conduit runs are minimized in the pathways between arrays. 512.4.2 Photovoltaic solar panel installation markings. Indoor and outdoor direct current conduit, enclosures, raceways, cable assemblies, junction boxes, combiner boxes, and main service and other disconnects shall have durable, retroreflective and, if outdoors, weatherproof, markings, in white capital letters with a height of not less than 3/8 inch (9.5 mm) on a red background, reading "WARNING: PHOTOVOLTAIC POWER SOURCE." Continuous installations, including conduit, raceways, enclosures and cable assemblies, shall be marked every 10 feet (3048 mm), within 1 foot (305 mm) of all turns or bends, and within 1 foot (305 mm) above and below all penetrations of roof or ceiling assemblies and all walls.
