Mcs say 600mm building regs is grey one report that it is 300mm another company that thinks its 400mm.
Pv clearance from edge of roof.
In article ibc 1509 7 2 it says that rooftop mounted pv systems must not diminish the fire classification of the roof system in order to meet the ibc code here one must ensure the system and equipment used have a ul fire tested class rating that either matches or exceeds that of the existing roofing material.
See ibc 2006 section 1013 5 mechanical equipment.
Anybody know the minimum clearance required between pv module edge of roof.
Should clearly indicate layout of panels dimensioned fdny clearances with any obstructions and overall dimensions.
This drawing can also show.
This means that if you have a horizontal pipe run that is not directly below the pv array the pipe must be at least 10 inches below the roof decking.
The design of roof structures need.
The roof upon which these systems are installed shall be designed and constructed to support the loads imposed by such systems in accordance with chapter 8.

R324 4 1 r324 4 1 1 roof live load.
The first requirement is that when pv circuits are run below roof surfaces outside of the array perimeter they shall be no less than 10 inches from the roof decking.

The pv system is looked at essentially like cladding and thus the wind load table for cladding is what is used to determine the load the panel system must resist depending on factors such as exposure windspeed roof area roof slope and where the panels are located on the roof such as near an edge or in the center.
Clearly note number of panels and roof pitch i e.
Pathways shall be over areas capable of supporting fire fighters accessing the roof.
