THE SHORT ANSWER
Wind behavior changes around roof geometry. A property-specific structural and racking design should address edge, corner and obstruction effects rather than maximize module count blindly.
Map the real geometry
Document ridges, hips, valleys, eaves, parapets, dormers and rooftop equipment. A simplified rectangle can hide important pressure and access conditions.
Ask for zone-based decisions
Have the qualified designer identify the criteria controlling setbacks, attachment patterns and rail spans. Do not interpret a marketing wind-speed number as approval for every roof position.
Balance production and resilience
Moving a module can affect shade, orientation, pathways and annual output. Compare a revised PVWatts model with structural and code requirements without trading required safety for projected kWh.
Carry changes through documents
The site plan, structural detail, equipment count, permit set and utility record should all reflect the accepted layout.
Before your next conversation
- Map complete roof geometry.
- Request zone-based details.
- Remodel production after changes.
- Update every project record.
