Understanding the Cal Fire Solar Photovoltaic Installation Guideline

Recommendations

Info

Exceptions to Section 2.0 (cont.) • Adequate ventilation opportunities beneath solar array (as with significantly elevated or widely‐spaced arrays) • Adequate ventilation opportunities afforded by module set back from o<strong>the</strong>r rooftop equipment (shading or structural constraints may leave significant areas open for ventilation near HVAC equipment, for example.) • Automatic ventilation device. • New technology, methods, or o<strong>the</strong>r innovations that ensure adequate fire department access, pathways and ventilation opportunities.
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. (see appendix) • Each roof face treated independently. • PV array and wiring is off limits to fire fighters.
