☀️ PV Solar Panel Wind Load Certification (Roof-Mounted)

✅ Certified Wind Load Letter for Rooftop Solar Panel Systems (FBC 2023 / HVHZ Compliant)

This site-specific wind certification letter ensures your PV solar panel installation complies with the Florida Building Code (FBC) 2023 – 8th Edition, ASCE 7-22, and all applicable High Velocity Hurricane Zone (HVHZ) requirements.

Whether you’re using a tilt-rack, curb-mounted, or flush-mounted solar system, we’ll determine the required wind uplift resistance and verify that your structural system (rails, attachments, anchors) can meet code.

🧾 What’s Included:

• ✔️ Signed & sealed engineering letter by Florida PE

• ✔️ Site-specific ASCE 7-22 wind pressure calculations

• ✔️ Roof zone uplift pressure summary (Zones 1–3)

• ✔️ Tributary area-based loads per panel or group

• ✔️ Verification of rail, anchor, and standoff capacities (if provided)

• ✔️ FBC and HVHZ permit compliance language

• ✔️ Ready-to-submit stamped PDF

🔋 Use Cases:

• Residential Rooftop Solar (Shingle, Tile, or Metal Roofs)

• Commercial PV Arrays (Flat Roof or Tilted)

• Flush-Mount & Tilt Rack Systems

• Rail-Based and Curb-Mounted Installations

• Retrofitted Systems Needing PE Review

📐 Engineering Specs:

• Wind Speed: Site Specific Vult or per HVHZ requirements (whichever is larger)

• Risk Category: II

• Exposure Category: C or D (site specific)

• Roof Zones Covered: Zone 1, 2, and 3

• Design Methodology: LRFD (Ch. 30, Pt. 4)

• Load Types Analyzed:

  • Uplift (main concern for permitting)

  • Overturning / Sliding (if rack specs are submitted)

💬 FAQs:

Do I need this for my solar permit?
Yes — most Florida jurisdictions require a sealed wind letter showing your panel system is code-compliant. This is a wind-specific service, doesn't include electrical, or solar system engineering or design.

What if I don’t have the rail specs?
We can calculate required loads and provide pressure values — your installer must ensure hardware meets or exceeds those loads.

Is this valid outside of HVHZ?
Yes — this can be used in all Florida counties. We adjust wind speed and exposure as needed.

What if the panels are ballasted on a flat roof?
Ballasted systems may require a separate ballast calculation or structural anchorage confirmation — contact us first.
