Solar Panel Wind Zone & Attachment Visualization

Illustrates how location (Wind Speed), surroundings (Exposure), building height, and roof dimensions influence wind zones. Select an attachment type and max span. Attachments (dots on rails) are placed on rafters based on calculated spacing needed to resist uplift vs. attachment strength, respecting the max span. Orange dots indicate rafters where the distance from the previous attachment exceeds the calculated requirement (but respects the max span).

Calculated Required Spacing:

(Max distance based on load vs. strength)

  • Zone 1 (Field): N/A ft
  • Zone 2 (Edge): N/A ft
  • Zone 3 (Corner): N/A ft

Actual placement also respects Max Span input and rafter locations.

Relative Uplift Factors:

  • Higher Wind Speed = Higher Pressure
  • Exposure D > C > B
  • Higher Building Height = Higher Pressure
  • Corners (3) > Edges (2) > Field (1)

Note: Simplified illustration. Real engineering required.

Surrounding Environment:

Reflects selected exposure category.
