XR Flush Mount System Certification - 7.22 - Rev B - 1 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com Report #7.22 XR10: Engineering Certification and Span Tables for the IronRidge XR10 Rail Flush Mount System, for Gable and Hip Roofs, Rev B. This report addresses the structural performance and code compliance of IronRidge’s XR Rail Flush Mount System. The contents of the report shall be reviewed in its entirety before application to any project design. The XR Rail 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 roof attachment with 3/8” stainless steel bonding hardware and the attachment is secured directly to the underlying roof structure. Assembly details of a typical XR Rail Flush Mount System installation and its core components are shown in Exhibit EX-0015. The IronRidge XR Rail 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. • Minimum Design Loads for Buildings and Other Structures, ASCE/SEI 7-22 • SEAOC (Structural Engineers Association of California) report PV2-2017 Wind Design for Solar Arrays • AC428, Acceptance Criteria for Modular Framing Systems Used to Support Photovoltaic (PV) Panels, November 1, 2012 by ICC-ES • Aluminum Design Manual (ADM) 2020, by the Aluminum Association, Inc. The span tables provided in this report are certified based on the structural performance of IronRidge XR Rails only with no consideration of the structural adequacy of the chosen roof attachments, PV modules, or the underlying roof supporting members. 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. This report certifies the IronRidge products referenced within this document and provides no determination of the project specific conditions including site loads, building profile, & roof zones, which remain the responsibility of the installer or system designer. The span tables included in this report provide the maximum allowable spans of XR Rail Flush Mount System for the respective loads and configurations listed, covering wind exposure categories B, C, & D, roof zones provided in ASCE 7 for enclosed and partially enclosed gable & hip roof profiles with roof slopes of 8° to 60°. The tabulated spans are applicable when the following conditions are met: A. Span is the distance between two adjacent attachment points and is to be measured with respect to the center of the attachment fastener. B. Each module shall be supported by 2 rails (2 rail system) or 3 rails (3 rail system). Spans are calculated based on 2 rail systems and are conservatively deemed applicable for 3 rail systems. C. The underlying roof slope, measured between the roof surface and horizontal plane, is 8º to 60º. D. The mean roof height, defined as the average of the roof eave height and the roof ridge height measured from grade for roofs with pitches above 10 degrees and defined as the eave height for roofs with pitches less than or equal to 10 degrees, does not exceed 30 feet. © 2024 IronRidge, Inc. XR Flush Mount System Certification - 7.22 - Rev B - 2 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com E. A clearance from the underside of the array to the roof surface of 2” minimum shall be provided and the height of the array, the distance from the module top surface to the roof surface (defined as h2), shall not exceed 10”. F. Module length and area shall not exceed the maximum values listed on the respective span tables. The maximum module length within the scope of this report is 98.5 inches. The maximum module length specified within ASCE 7-22 is 80.4 inches. Wind pressure loads used to generate the span tables for modules with lengths above this value are based on the wind tunnel study “Wind Loads on photovoltaic arrays mounted on sloped roofs of low-rise building, parallel to the roof surface.” referenced in ASCE 7 Section C29.4.4. G. All Flush Mount components shall be installed in a professional workmanlike manner per IronRidge’s Flush Mount Installation Manual and other applicable standards for the general roof construction. 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 7-22 Table 1.5-1. 2. Wind speed shall conform to ASCE 7-22 Fig. 26.5-1B (for Risk Category II) and applicable state & local county/city amendments to the IBC. No special wind topographic features are included and both topographic coefficient (Kzt) and wind ground elevation factor (Ke) are taken as 1.0. 3. Snow load used in the span tables is the ground snow and shall conform to ASCE 7-22 Fig. 7.2-1B 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, it shall first be converted to a ground snow following the local building code/ amendments before the application of the attached span tables. 4. No special snow conditions are considered including unbalanced, drifting, sliding, retention, or ponding snow. No rain-on-snow surcharge load is considered. The span tables do not apply to buildings which are intentionally kept below freezing, kept just above freezing, or unheated without first converting the snow load based on the difference in Thermal Factor and snow sliding. The Thermal Factor, Ct, is assumed to be 1.101, the roof exposure factor is assumed to be 1.0, and the Sliding Factor is based on ASCE 7-22 Figure 7.4-1b for a warm roof with unobstructed slippery surfaces. 5. The span tables reflect the ASCE 7 prescribed earthquake loads with the maximum magnitudes being: a) For ground snow no greater than 58psf: S s ≤ 2.0g for Site Class A, B, C, & D. b) For ground snow greater than 90psf: S s ≤ 1.0g for Site Class A, B, C, & D. c) For ground snow between 58 and 90psf: S s ≤ 1.5g for Site Class A, B, C, & D. 6. Roof zones are defined by ASCE 7-22 Figure 30.3-2B to Figure 30.3-2G. Roof zone size and location to be used with the spans in this report are depicted in Figures 2 and 3 below each span table. 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. 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. This factor may not be used in determining maximum cantilever length. © 2024 IronRidge, Inc. XR Flush Mount System Certification - 7.22 - Rev B - 3 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com 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 techsupport@ironridge.com. 11. Systems using CAMO module clamps shall be installed with the following guidance: a) For single module installations (orphan modules), CAMO clamps shall not be installed in regions that experience ground snow loads in exceedance of what is listed in the following table. Such scenarios are shown by asterisks in the applicable span tables b) 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. Figure 1: CAMO Module Frame Dimensional Requirements Maximum Ground Snow load for Orphan Modules using CAMO per ASCE 7-22 Module Area 21.7 ft2 23.5 ft2 28.0 ft2 30.5 ft2 Ground Snow 80 psf 75 psf 60 psf 55 psf © 2024 IronRidge, Inc. XR Flush Mount System Certification - 7.22 - Rev B - 4 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com Spans for Exposed and Edge Modules Span values for Exposed and Edge module conditions, as defined below, are included in the attached span tables and shall be used when each condition exists. A module is defined as Exposed (per Section 29.4.4 of ASCE 7) if the distance from any of its free edges (an edge with no connectivity to other modules) to its facing roof edge (such as eave, ridge, rake, or hip) is greater than 0.5h (h is ASCE defined building height) AND if the distance from the same free edge to any other adjacent array or panel is greater than 2h2 where h2 refers to the array height. A module is defined as an Edge Module when its distance from any side of the module to its facing perimeter roof edge (such as eave, ridge, rake, or hip) is less than 2 times the height of the array (2h 2) where h2 is measured from the roof surface to the top surface of the module. The maximum allowable span for Exposed or Edge modules shall be the lesser of the following two: 1. The span value for the Exposed or Edge module condition. 2. The span value determined by site wind speed and ground snow load. The allowable spans and cantilever shall only be applied to the portion of rail directly under Exposed or Edge Modules. Additionally, the shaded cells for the Exposed and Edge module conditions indicate conditions in which UFO Mid Clamp connection capacity is exceeded. If such conditions are encountered, contact techsupport@ironridge.com.

Those systems with unique characteristics may be handled with small additions to this Expedited Permit Process or may require much more information, depending on the uniqueness of the installation. The following pages contain forms for the Micro-Inverter to use with the Expedited Per- mit Process. The Standard String, AC Module, and Supply-Side Connection forms are also available as interactive PDF files at www.solarabcs.org/permitting. In jurisdic- tions that have adopted the Expedited Permit Process for PV Systems, these forms can be filled out electronically and submitted in either printed form and via email. An elec- tronic format is used so that the supplied information is standardized and legible for the local jurisdiction. Expedited Permit Process for PV Systems — Micro-Inverter 2 Expedited Permit Process for Small-Scale PV Systems Micro-Inverter The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review, and when an installation is more complex. It is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required Information for Permit: 1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3’ perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specification sheets and installation manuals (if available) for all manufactured components including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1: Structural Review of PV Array Mounting System Is the array to be mounted on a defined, permitted roof structure? l Yes l No If No due to non-compliant roof or a ground mount, submit completed worksheet for the structure WKS1. Roof Information: 1. Is the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc…)__________________________ ____________________________________________________________________________________________________ If No, submit completed worksheet for roof structure WKS1 (No = heavy masonry, slate, etc…). 2. Does the roof have a single roof covering? l Yes l No If No, submit completed worksheet for roof structure WKS1. 3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk).____________________________ Mounting System Information: 1. Is the mounting structure an engineered product designed to mount PV modules with no more than an 18” gap beneath the module frames? l Yes l No If No, provide details of structural attachment certified by a design professional. 2. For manufactured mounting systems, fill out information on the mounting system below: a. Mounting System Manufacturer ___________Product Name and Model#________________________________ b. Total Weight of PV Modules and Rails ___________lbs c. Total Number of Attachment Points____________ d. Weight per Attachment Point (b÷c)_________________lbs (if greater than 45 lbs, see WKS1) e. Maximum Spacing Between Attachment Points on a Rail ______________inches (see product manual for maximum spacing allowed based on maximum design wind speed) f. Total Surface Area of PV Modules (square feet)_________________ ft2 g. Distributed Weight of PV Module on Roof (b÷f)_______________ lbs/ft2 If distributed weight of the PV system is greater than 5 lbs/ft2, see WKS1. Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: 1. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The total inverter capacity has a continuous ac power output 13,440 Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One of the standard electrical diagrams (E1.1, E1.1a, E1.1b, or E1.1c) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can effectively communicate, provide an alternative diagram with appropriate detail.
