You''ll want to reference codes that call out how much of a percentage of the entire plan-view roof is covered and if your array is under that percentage you can get away with an 18" setback.
Home Solar 101 Why does your design have setbacks of the solar panels from the roof line? By Jen Olson March 16, 2018. Solar 101. Fire setbacks for solar PV systems are required by the IBC (International Building Code) and
In most cases, solar arrays are required to have a minimum of 18 inches set back from the ridge of the roof and may also require a three-foot pathway along one of the
3 foot setback from the ridge if PV area is more than 33% of the roof; 1.5 feet setback from the ridge if PV area is less than 33% of the roof; 3 feet on one side for each roof; No setback on ridge if there is no PV on the opposite roof; No setback for flat roofs (less than 9.5 degree pitch) You can see the current code for Virginia here.
“For each roof plane with a photovoltaic array, a minimum 36 in. (914 mm) wide pathway from the lowest roof edge to ridge shall be provided on the same roof plane as the
Not all surfaces of a roof are solar-friendly; in the northern hemisphere, south-facing, unshaded exposures are the prime real estate for solar-panel installations. When panels are to be installed, the existing roof must be verified to either meet the current prescriptive roof design requirements in Chapter 8 or be analyzed and approved by

There is no setback requirement on eaves. 36" setback requirement at peaks and rake edges (I have a hip roof—no rakes). However, the 36" is not straightforward. What is actually required is
It has the temperature characteristics of fixed tilt modules, while still having the shape of a flush mount design. Fixed-tilt modules are tilted up, along a flat plane (e.g. a flat commercial roof or a ground-mounted array). Flush-mount modules are flush along a single plane (e.g. an array on the side of a barn, or a residential array). Flush

This is accomplished by issuing design guidelines on where roof-mounted panels can be installed. Mountain View Solar is now starting the design for every residential system to follow the 2018 International Fire Code. This is a key piece of good design, so each project is compatible with the local permitting guidelines for quick permitting approval.
According to Cal Fire''s Solar Photovoltaic Installation Guidelines below are illustrations of currently enforced fire setbacks/pathways for residential solar system installations. Any roof with pitch equal or less than 2 in 12 (9.46 degrees) doesn''t require any setbacks/pathways. Full text of the California Residential Code regarding the access and
Next, enter the setbacks for pitched roof facets as well as for flat roof facets. You may define a setback for every edge type of the roof including eaves, ridges, valleys/hips, rakes, and around obstructions. To get started, on the Solar Design tab, click the Fire Setbacks tool. Under Jurisdiction, select the setback applicable to your design.
My original plan, ignorant of setbacks, was to completely cover the south face of my roof. I could''ve fit 16 panels. I would''ve had 8s2p strings on the roof and two 8s1p strings on the ground. 9 panels on the roof is 30% of my total roof area and I will happily change my arrangement to 9s1p on the roof and 9s1p, 9s2p on the ground.
Roof Ventilation—Residential Roof Layouts Ventilation (IFC 605.11.3.2.4) • 3'' space along ridge of roof – Ridge setback based on enough room to make 2'' wide ventilation cut. – ASCE 7, Minimum Design Loads for Buildings, requires this setback in high wind locations (e.g. eastern seaboard) • No rooftop disconnect requirement.
