Present a one-line with clear conductor sizes, overcurrent devices, grounding, bonding, and points of connection labeled consistently with the site plan. Use standard symbols, page numbers, revision boxes, and manufacturer references. Legible callouts, readable scales, and photos of service equipment resolve doubts before anyone emails you corrective comments.
Roof approvals hinge on showing that rafters, trusses, attachments, and sheathing can safely carry loads. Provide stamped calculations or prescriptive tables, wind exposure categories, fastener patterns, and pull-test data if available. For ballasted systems, include uplift analysis and pathways; for steel, show corrosion protection, especially near coastal conditions.
Attach spec sheets and certifications for modules, inverters, optimizers, and racking, demonstrating compliance with UL 1703 or IEC equivalents for modules, UL 1741 SB and IEEE 1547-2018 for inverters. Call out rapid shutdown capability, temperature ratings, and grounding hardware. Clear data shortens review time and prevents follow-up requests.
