Step 6 (Detailed): Review Structural PV Array Mounting Requirements

This version of Step 6 is for jurisdictions requiring detailed structural PV array mounting information. Skip this step if using Step 6 (Simplified). The goal of this Checklist is to provide assurance that a solar array does not overload (1) an existing residential roof, or (2) the attachments to the roof. These rules do not address the structural sufficiency of the components of the array above the roof. The components above the roof are engineered by the mounting system manufacturers. ***NOTE: These guidelines are a living document and may be revised. Last updated: 9/16/21***

A. General Site and Array Requirements (all square boxes must be checked; where slanted check box sub-options occur, one sub-option must be checked):

B. Roof Information (all must apply):

C. Array Mounting Equipment Information (all must be defined):

D. General Framing-Attached Array Requirements (all square boxes must be checked; where slanted check box sub-options occur, one sub-option must be checked):

E. High Wind Framing-Attached Array Additional Requirements (All of A. through D. complies and design wind speed does not exceed 180 mph):

F. Low Wind and Low Snow Load Reduced Framing-Attached Array Requirements (design wind speed does not exceed mph and ground snow load no greater than 10 pdf):

G. Sheathing-Attached Array Requirements (all square boxes must be checked; where slanted check box sub-options occur, at least one sub-option must be checked):
