Plan Set Requirements

Absolutely - here’s a cleaned up, organized, and de-duplicated version that keeps the technical intent but is much easier to read and act on:

Structural Requirements

• Provide maximum rafter spans for all roof areas.
• Any spans exceeding Structural Criteria Table 2 require a structural analysis demonstrating the roof’s ability to support the proposed PV loads.

Tilt Mount Array - Gravity & Wind Analysis

• Stating that gravity loads are below current code requirements is not sufficient.
• Provide a specific structural analysis verifying the existing roof framing can support:
• Gravity loads from the tilt-mounted PV system
• Wind loads imposed by the tilt-mounted array
• Live load may not be reduced or removed beneath tilted modules, as sufficient clearance exists for access.
• Revise calculations or provide additional justification accordingly.

Fire Classification

• AHJ requires Class A fire rating for all PV equipment, including:
• Modules
• Racking
• Associated system components

Roof Plan

• Provide maximum rafter spans for all roof areas. (Spans that exceed structural criteria table 2 will require a structural analysis to justify the adequacy of the roof to withstand the proposed PV loads.)
• Include all conduit run locations

Attachment Detail

• Specify all lag screws to be STAINLESS STEEL

Electrical Diagram

Standard

Electrical Diagram Notes

• All wiring must be properly supported by devices or mechanical means designed and listed for such use, and for roof-mounted systems, wiring must be permanently and completely held off of the roof surface.
• The inverter output connection shall be placed on the opposite end of the main breaker on the busbars per CEC 705.12(D)(2)(3).
