Solar Panel Wind Load Calculator

Model design wind load on a photovoltaic module with a simplified ASCE-style equation that multiplies dynamic pressure by exposure and pressure factors.

Preliminary estimate only; consult a licensed engineer for code-compliant structural calculations.

Examples

  • 35 m/s wind, exposure 1.2, coefficient 0.8, area 4.5 m² ⇒ 520.63 N
  • 28 m/s wind, exposure 0.9, coefficient 1.1, area 6.0 m² ⇒ 283.89 N

FAQ

Does this replace structural analysis?

No. It offers a quick estimate; final mounting design should follow the applicable building code and be reviewed by an engineer.

Can I input mph instead of m/s?

Convert mph to m/s first (1 mph ≈ 0.44704 m/s) to keep the calculation accurate.

What if the panel area changes?

Enter the projected area of the array that faces the wind. Larger areas increase the calculated force proportionally.

Additional Information

  • Dynamic pressure uses 0.613 × V² (SI units) where V is wind speed in m/s.
  • Exposure factor adjusts for terrain or height, while the pressure coefficient captures panel tilt and shape effects.
  • Multiply the result by a safety factor per your local structural code before finalizing designs.
