Setback Notes: Panels and modules shall be located in a manner that provides a minimum 3 feet wide (968 mm) clear perimeter around the edges of the roof. The access pathway shall be capable of supporting the firefighters accessing the roof, i.e. over an exterior load-bearing wall. This requirement holds true for all roof types including hip, gable, and flat roofs. Access pathway clear width shall be over the load bearing wall inward. Not over the eaves. Panels/modules shall be located no closer than 6 inches minimum (12 inches preferred) to a hip or valley if placed on both sides of the hip or valley. Where panels/modules are located on only one side of a hip or valley that is of equal length, the panels may be placed directly adjacent to the hip or valley. Panels/modules shall be located on only one side of any ridge and shall be located no higher than 1 foot below the ridge. EXCEPTIONS: 1. Where solar panels are located a minimum of 5 feet from the ridge on the opposing side. 2. Where alternative means of allowance for smoke ventilation operations have been approved by the Fire Chief or Fire Marshal.
