Arden Hills, MN 55112 REFERENCE: Greseth, Gabe Residence: 20806 Greenwood Avenue, Lakeville, MN 55044 Solar Array Installation To Whom It May Concern: Per your request,we have reviewed the existing structure at the above referenced site.The purpose of our review was to determine the adequacy of the existing structure to support the proposed installation of solar panels on the roof as shown on the panel layout plan. Based upon our review, we conclude that the existing structure is adequate to support the proposed solar panel installation. Design Parameters Code: 2020 Minnesota Residential Code (2018 IRC) Risk Category: II Design wind speed, Vult: 115 mph (3-sec gust) Wind exposure category: C Ground snow load, Pg: 50 psf Connection to Roof Mounting connection: (1) 5/16" lag screw w/ min. 2.5" threaded embedment into framing at max. 48" o.c. (portrait and landscape) along rails Install (2) rails per row of panels, evenly spaced Maximum panel dimension: 74x41.1 in Rail cantilever shall not exceed 50% of connection spacing Conclusions Based upon our review,we conclude that the existing structure is adequate to support the proposed solar panel installation. The glass surface of the solar panels allows for a lower slope factor per ASCE 7,resulting in reduced design snow load on the panels.The gravity loads,and thus the stresses of the structural elements,in the area of the solar array are either decreased or increased by no more than 5%.Stress decreases or increases of no more than 5%are considered acceptable. Therefore, the structure is permitted to remain unaltered. The solar array will be flush-mounted (no more than 10"above the roof surface)and parallel to the roof surface.Thus,we conclude that any additional wind loading on the structure related to the addition of the proposed solar array is negligible. The attached calculations verify the capacity of the connections of the solar array to the existing roof against wind (uplift), the governing load case.Increases in lateral forces less than 10%are considered acceptable.Thus the existing lateral force resisting system is permitted to remain unaltered. 651 W.

The unique water seal design is both elevated and encapsulated, delivering redundant layers of protection against water intrusion. In addition, the twist-on Cap perfectly aligns the rail attachment with the lag bolt to maximize mechanical strength. FlashFoot2 Twist-On Cap FlashFoot2’s unique Cap design encapsulates the lag bolt and locks into place with a simple twist. The Cap helps FlashFoot2 deliver superior structural strength, by aligning the rail and lag bolt in a concentric load path. Single Socket Size A custom-design lag bolt allows you to install FlashFoot2 with the same 7/16” socket size used on other Flush Mount System components. Three-Tier Water Seal FlashFoot2’s seal architecture utilizes three layers of protection. An elevated platform diverts water away, while a stack of rugged components raises the seal an entire inch. The seal is then fully-encapuslated by the Cap. FlashFoot2 is the first solar attachment to pass the TAS-100 Wind-Driven Rain Test. Water-Shedding Design An elevated platform diverts water away from the water seal. © 2016 IronRidge, Inc. All rights reserved. Visit www.ironridge.com or call 1-800-227-9523 for more information.

Date: September 7th, 2021 Re: Structural Certification and Span Tables for the 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 applying 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 7-16 Minimum Design Loads for Buildings and Other Structures (ASCE 7-16) •2018 International Building Code (IBC-2018) •2020 Minnesota Building Code •2015 Aluminum Design Manual (ADM-2015) •Report SEAOC (Structural Engineer Association of California) PV2-2017 Wind Design for Solar Arrays 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 provided in ASCE 7-16 for gable & hip roof profiles, and roof slopes of 8° to 45°. The tabulated spans are applicable when 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.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 conservatively deemed acceptable for 3 rail systems. 3.The underlying roof slope, measured between the roof surface and horizontal plane, is 8º to 45º. 4.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. 5.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”. 6.Module length and area shall not exceed the maximum values listed on the respective span tables. 7.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 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 7-16 Table 1.5-1. 2. Wind speed shall conform to ASCE 7-16 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 7-16 Fig. 7.2-1 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, it shall first be converted to a ground snow following the local building code/ amendments before the application of the attached span tables. 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. 4. The span tables reflect the ASCE 7 prescribed earthquake loads with the maximum magnitudes being: (a) For ground snow no greater than 42psf: Ss ≤ 2.0g for Site Class A, B, C, & D. (b) For ground snow greater than 65psf: Ss ≤ 1.0g for Site Class A, B, C, & D. (c) For ground snow between 42 and 65psf: Ss ≤ 1.5g for Site Class A, B, C, & D. 5. Roof zones are defined by ASCE 7-16 Figure 30.3-2A to Figure 30.3-2I and are organized into three groups in which the zones share the same External Pressure Coefficients (GCp). Roof zones comprising each group along with each roof zone’s size and location are depicted in Figures 2 and 3 below each span table. 6. 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”. 7. 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. 8. 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. 9. 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. © 2021 IronRidge, Inc. MN Flush Mount System Certification Letter - 3 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com 10. Systems using CAMO module clamps shall be installed with the following guidance: a) 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 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 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. 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. Additionally, irrespective of the lesser span, the shaded cells for the Exposed and Edge module conditions which reflect the UFO clamp usage limitation detailed in note 9 of page 2 shall apply to the respective condition. 1. Exposed Module conditions: A module is defined as Exposed (per Section 29.4.4 of ASCE 7-16) 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 its free edge to any other adjacent array or panel is greater than 4 feet. The allowable spans and cantilever shall only be applied to the portion of rail directly under Exposed Modules. 2. Edge Module conditions: 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 (2h2) where h2 is measured from the roof surface to the top surface of the module. The allowable spans and cantilever shall only be applied to the portion of rail directly under Edge Modules. Additionally, if the roof edge is the eave or ridge, only the rail nearest to that roof edge shall be considered for this span adjustment. © 2021 IronRidge, Inc.MN Flush Mount System Certification Letter - 4 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523IronRidge.com The span tables provided in this letter 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.
