IronRidge Solar Racking Approved in Florida
In 2020, IronRidge became the first High Velocity Hurricane Zone (HVHZ) approved solar system in accordance with 7-10 building code. We are happy to share that the Flush Mount System is now HVHZ-approved in accordance with 7-16 as well. We are committed to safe solar, even in extreme environments.
The rigorous evaluation process for Florida Product Approval includes testing for resistance to high wind forces (TAS 202) and wind-driven rain [TAS 100(A)], and ongoing auditing of quality assurance programs.
Our Florida Product Approval (FL#29843) covers all Flush Mount components and applies to all regions of the state of Florida both inside and outside the high-velocity hurricane zones (HVHZ), up to 100 PSF of wind pressure. The approval also lists allowable rail spans for configurations using either XR10, XR100, or XR1000 mounting rails as well as multiple IronRidge roof attachments.
Maximum Wind Uplift Pressures
The following tables were prepared by IronRidge to provide a quick reference for the maximum wind uplift pressures on gable and hip roofs at different tilt angles (see Florida Approval Pressure Tables document for official stamped version). Other system documentation can be found on our Pitched Roof Resources page.
Does this approval work with any solar module?
Every module has its own tested capacity for resisting wind pressure. Check the module manufacturer’s cut sheet or manual for load rating. A third rail may be required to increase the module load rating to meet the uplift pressure.
Where can I find the documentation?
IronRidge’s Florida Product Approval (FL29843) is available on the IronRidge website or through the FBC’s approved products database: https://www.floridabuilding.org/pr/pr_app_lst.aspx
Do I still need an engineer to stamp my project?
This approval covers structural engineering of solar racking and should eliminate the need for project-specific engineering. Confirm with your jurisdiction any local requirements.
Does this apply to Tilt or Ground Mount systems?
This approval only applies to the IronRidge Flush Mount system on roof pitches 2:12 to 12:12 (9.5° to 45°).
Does this apply to other hurricane-prone regions?
Florida’s building code and testing standards are often used or cited in other such regions, but official approval depends on the local Authority Having Jurisdiction.
