© 2021 IronRidge, Inc. MN Flush Mount System Certification Letter - 1 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com Attn: Corey Geiger, COO, IronRidge Inc. Date: March 15th, 2021 Re: Structural Certification and Span Tables for IronRidge Flush Mount System This letter addresses the structural performance and code compliance of IronRidge’s Flush Mount System. The contents of the letter shall be read in its entirety before being applied to any project design. The Flush Mount System is a proprietary rooftop mounting system used to support photovoltaic (PV) modules installed in portrait or landscape orientation and set parallel to the underlying roof surface. PV modules are supported by extruded aluminum XR Rails and secured to the rails with IronRidge mounting clamps. The XR Rails are side mounted to a selected roof attachment with 3/8” stainless steel bonding hardware and then attached directly to the roof structure or to a stanchion that is fastened to the underlying roof structure. Assembly details of a typical Flush Mount installation and its core components are shown in Exhibit EX-0015. The IronRidge Flush Mount System is designed and certified to the structural requirements of the reference standards listed below, for the load conditions and configurations tabulated in the attached span tables. • ASCE/SEI 7-10 Minimum Design Loads for Buildings and Other Structures (ASCE 7-10) • 2015 International Building Code (IBC-2015) • 2015 Minnesota State Building Code • 2015 Aluminum Design Manual (ADM-2015) The tables included in this letter provide the maximum allowable spans of XR Rails in the Flush Mount System for the respective loads and configurations listed, covering wind exposure categories B, C, & D, roof zones 1, 2 & 3, and roof slopes from 8º to 45º. The span tables are applicable provided that the following conditions are met: 1. Span is the distance between two adjacent roof attachment points (measured at the center of the attachment fastener) 2. The underlying roof pitch, measured between roof surface and horizontal plane, is 8º to 45º. 3. The mean roof height, defined as the average of the roof eave height and the roof ridge height measured from grade, does not exceed 30 feet. 4. Module length and area shall not exceed the maximum values listed on the respective span tables. 5. All Flush Mount components shall be installed in a professional workmanlike manner per IronRidge’s Flush Mount installation manual and other applicable standards for general roof construction practice. © 2021 IronRidge, Inc. MN Flush Mount System Certification Letter - 2 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com The parameters and adjustments allowed in the span tables are defined as the following: 1. The Flush Mount System is designed as a Risk Category II structure as defined by ASCE 7-10 Chart 1.5-1. 2. The wind speed selection shall conform to ASCE 7-10 Fig. 26.5-1A (Risk Category II wind) and any state & local county/city amendments to the IBC. No special wind topographic features are included in the span tables and the topographic coefficient (Kzt) is taken as 1.0. 3. The snow load used in the span tables is the ground snow and shall conform to ASCE 7-10 Fig. 7-1 and applicable state & local county/city amendments to the IBC. If the local jurisdiction specified snow load is in the format of a flat roof snow load, it shall first be converted to a ground snow following the local building code/amendment before the application of the attached span tables. No special snow conditions are considered including unbalanced, drifting, sliding, retention, or ponding snow. The span tables do not include buildings which are intentionally kept below freezing, kept just above freezing, or unheated. 4. The span tables reflect the ASCE 7 prescribed earthquake loads with the maximum magnitudes being: 1) For ground snow no greater than 42psf: Ss ≤ 2.0g for Site Class A, B, C, or D. 2) For ground snow greater than 65psf: Ss ≤ 1.0g for Site Class A, B, C, or D. 3) For ground snow between 42 and 65psf: Ss ≤ 1.5g for Site Class A, B, C, or D. 5. Roof zone size and definition conforms to ASCE 7-10 Fig. 30.4-2A to 30.4-2C. 6. Allowable span length in the charts may be multiplied by a factor of 1.08 if the rails are continuous over a minimum of three spans. 7. The maximum rail cantilever length, measured from the rail end to the nearest attachment point, shall be the lesser of the following two conditions: 40% of the allowable span provided for the respective load & configuration condition from the span tables, or 36”. 8. An array to roof clearance of 2” minimum must be provided. 9. No splices are allowed in the rail cantilever. For each XR splice type install per the following requirements: a) XR Bonded Splice cannot be installed in the center 1/3 of interior spans, or the outer 2/3 of end spans. b) BOSS Splice can be installed at any location within a span. 10. Shaded cells of the span tables indicate conditions in which UFO Mid Clamp connection capacity is exceeded. If such conditions are encountered contact support@ironridge.com. 11. When a roof attachment listed in IronRidge’s Flush Mount installation manual is considered, the span values provided in this letter can be adjusted using IronRidge’s online Design Assistant by checking the capacity of the selected roof attachment against the reaction forces provided in Design Assistant. © 2021 IronRidge, Inc. MN Flush Mount System Certification Letter - 3 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com 12. Systems using CAMO module clamps shall be installed with the following guidance: 1) For single module installations (“orphan modules”) using modules with a length greater than 67.5”, CAMO clamps shall not be installed in regions that experience ground snow loads of 70psf and greater: such scenarios are shown by asterisks in the applicable span table. 2) CAMO will function within a module’s design load ratings. Be sure the specific module being used with CAMO meets the dimensional requirements shown in the figure below and that the module selected is suitable for the environmental conditions of a particular project.

It is the responsibility of the installer or system designer to verify the structural capacity and adequacy of the aforementioned system components in regards to the applied or resultant loads of any chosen array configuration.
