Taggart, Vice President Products Subject: Ground Mounting System — Structural Analysis — 4 Module Dear Sir: June 3, 2016 Page l of 51 We have analyzed the subject ground mounted structure and determined that it is in compliance with the applicable sections of the following Reference Documents: Codes: ASCE/SEI 7-10 Min. Design Loads for Buildings & Other Structures California Building Code, 2016 Edition Other: AC428, Acceptance Criteria for Modular Framing Systems Used to Support PV Modules, dated Effective November 1, 2012 by ICC -ES Aluminum Design Manual, 2015 Edition IronRidge Exhibit EX -0001 The structure is a simple column (pier) and beam (cross pipe) system. The piers & cross pipes are ASTM A53 Grade B standard weight (schedule 40) steel pipes or Allied Mechanical Tubing. Please refer to Exhibit EX -0001 for approved pipe geometry and material properties. The tops of the piers are connected in the E -W direction by the cross pipes which cantilever over and extend past the end piers. The cross pipes are connected by proprietary IronRidge XR1000 Rails spanning up and down the slope which cantilever over and extend past the top and bottom cross pipes. There are typically two rails per column of modules. The modules are clamped to the rails by the IronRidge Module Mounting Clamps as shown in the attached Exhibit. Gravity loads are transferred to the piers and foundations by the rails and cross pipes acting as simple beams. For lateral loads the system is either a cantilever structure or, when diagonal braces are provided, a braced frame. The effect of seismic loads (for all design categories A -F) have been determined to be less than the effect due to wind loads in all load conditions and combinations. The pier spacing in the N -S direction is 7'-6". The pier spacing in the E -W direction is selected from load tables determined by the structural design for the specified slope, wind load, and snow load. The governing criteria for the pier spacing is either the spanning capacity of the cross pipes or the cantilever capacity of the pier. Simplified Load Tables IA -F & 2A -F are included herein for reference. More comprehensive information covering all load combinations is available at the IronRidge website, IronR.idge.com: Starling Madison Lofquist, Inc.

If installing the system on a metal roof, you must ensure that the system is bonded to the roof in compliance with grounding methods as required by the AHJ. - This section is intended to provide a well-rounded understanding of all aspects of grounding, disconnect - '� requirements, and NEC compliance for SunPower Equinox; it contains excerpts from the SunPower AC Module Safety ' and Installation Instructions (#51744), as well as references to the applicable NEC Articles and UL Standards.,' SunPower AC Modules. meet all current code requirements for rapid shutdown as defined in NEC 690.12 Rapid �a Shutdown of PV Systems on Buildings. As part of the UL 1741 listing of the SunPower AC Module product being utility interactive, upon turning off the AC disconnect to de -energize the circuit to the AC Modules on the roof, each AC i Module output will shut off within 0.16 seconds to comply with IEEE 1547. In this manner, all wiring leaving each AC Module complies with the,controlled conductor limits in 690.12. The SunPower AC Module is one of the components that electrically bonds all of the metallic non-current. ' carrying components in the system, and is Listed to UL 1741. • Only AC equipment grounding requirements apply when installing Listed AC modules to racking that is Listed to ; UL 2703—neither DC system grounding requirements.(GEC) nor DC equipment grounding requirements (EGC) apply. ` The equipment grounding conductor (EGC) that's built into and Listed with the AC Module cable system is sized =� appropriately and meets all of the AC equipment grounding requirements for the system. • Th A i ranch circuit wiring from the distribution panel to the arra must include an equipment .z The C dedicated b g p Y 15 5:5 grounding conductor (EGC) in the same raceway or cable as the AC circuit conductors. This EGC must be 0 �� connected to the green conductor of the transition cable, which is part of the AC module cable system.!'1� The AC Module connectors (plugs and receptacles)'are rated for disconnect.' O 4 • If a module is removed from a circuit (for service or replacement, for example), remember that -the AC iq `) Module cable. system is daisy -chained and that therefore you must first disconnect all power and then Document #518101 RevA 17 SunPower Proprietary install a temporary EGC to bridge the gap by inserting an AC extension cable or other means, in order to maintain effective ground continuity to subsequent modules. Disconnecting a module from the circuit removes voltage and might also remove ground from the other downstream modules in the circuit. Extreme care should be taken to ensure that no other energized sources are adjacent to these, ungrounded modules. • A grounding electrode conductor (GEC) for the module or array is not required because the DC power is internal to the AC Module. The existing AC GEC at the premises or structure utility service serves as the NEC -required GEC for the AC Module system. • The AC cable grounding path has been tested by an NRTL, and its electrical continuity from the AC cable ground pin to the module frame has been evaluated as part of the AC Module Listing. • The AC Module interconnecting cable system provides an internal EGC for grounding the AC Modules. • Neither the AC Modules nor the array require a GEC. The AC Module must be connected to a dedicated AC branch circuit with an appropriately sized equipment grounding conductor (EGC). The EGC must be connected to a grounding electrode using the existing premises wiring system, typically originating at the building service entrance or service panel. • The AC interconnecting cable system attached to each module's microinverter is fully insulated and includes an internal EGC. The grounding pin is longer than the others in the plug, providing a "first to make, last to break" connection sequence. • The green conductor in the AC cable is connected to the EGC from the utility dedicated branch circuit ("the building ground"). • The AC ground wire inside the microinverter terminates on the microinverter chassis with a bolted connection, and is environmentally sealed. • The microinverter chassis is bonded to the module frame with stainless steel hardware to provide ground continuity to the module frame. Each SunPower AC Module includes a factory -integrated microinverter (MI) that does not require a neutral wire to be connected to it for operation or for compliance with IEEE 1547. Power produced is conducted on the L1-L2 240 VAC or 208 VAC grid connection. Utility interactive functions in the MI circuitry have been evaluated to IEEE 1547, and use the ground wire instead of the neutral to determine grid values. This functionality is part of its UL Listing. This product must only be connected to a single-phase system (LA) of a premises with the neutral (N) bonded to ground at the service entrance per code. (The MI does not reference the N to ground internally, therefore this reference must be accomplished only at the service entrance.) Ensure that the installation site has a high-quality N -to -ground reference at the service. The MI determines L -N voltages based on measuring internally from L to the MI chassis, which is connected to the EGC. Document #518101 RevA 18 sunPower Proprietary 4.1 NEC Compliance and the Ground Path The following are the grounding -related NEC Articles and applicability for SunPower AC Modules on rooftops: • 690.31(D) requires that the equipment be grounded using an equipment grounding conductor (EGC) inside the AC module cable. 690.41 does not apply to AC modules. • 690.42 does not apply to AC modules. • 690.43 covers equipment grounding, which is the only required type of grounding for an AC module. o 690.45 specifies that EGCs should be sized based on 250.122. • 690.46 modifies 690.45 when the EGC is not protected within a raceway. • 690.47 does not apply to AC modules: ■ 690.47(A) does not apply because the AC "system" was already existing on the premises (already installed per Section 250 of the code) and the AC Module system connects to the load side of this service. • 690.47(B) applies to DC systems; it does not apply to AC modules. • 690.47(C) does not apply (see 690.47(B)). • 690.47(D) only provides guidance for a "dc grounding electrode conductor." 690.49 does not apply. Note as well that Section 4.1 of the SunPower AC Module Safety and Installation Instructions (#51744) explains: As a Listed product, "SunPower AC modules shall be installed and used in accordance with any instructions included in the listing or labeling' (110.3(B)). In addition, SunPower AC Modules "shall be grounded using the integrated equipment grounding conductor ... no additional grounding conductor attachment to the AC module is required." 4.2 System Ground Path The system features: • Integrated module -to -rail as well as adjacent -module bonding (achieved through the mid clamp and end clamp). • Integrated rail -to -rail bonding (achieved through the self -drilling splice screws and the splice). • System bonding is achieved through the equipment ground conductor (EGC).

Document #509506 Rev B I '✓ MAFFEI STRUCTURAL ENGINEERING 11 August 2014 Guillaume Carre SunPower Corporation 1414 Harbour Way South Richmond, CA 94804 Subject: SunPower Invisimount Design Tool Structural Calculations Dear Guillaume, Per your request, we are pleased to present the findings from our review and testing of SunPower's Invisimount Design Tool, an online tool that: • Evaluates structural design loads on SunPower Invisimount solar arrays • Evaluates the maximum allowable spacing of attachments of the system to the roof to resist design loads • Estimates the bill of materials for specific projects to assist with ordering parts from SunPower SCOPE OF THE TOOL Invisimount by SunPower is a solar panel support system for installing solar photovoltaic arrays on sloped roofs of buildings. Typically such buildings are residential with shingle or tile roofs. Each row or column of modules is supported by two rails, which are attached to the roof structure. The number and spacing of attachments to the roof structure can vary depending on, for example, structural loads at a particular site, the type of attachment hardware used, and spacing of the building rafters. The attached "Engineering Basis of Calculations" describes the scope of the Invisimount Design Tool, its calculation procedures, and assumptions for use. SCOPE OF OUR REVIEW Maffei Structural Engineering 'collaborated with SunPower on the development of the Invisimount Design Tool, including the following tasks related to structural calculations: • Provided documents describing applicable building code formulas and the calculation procedure to be implemented by SunPower's programming team • Worked with SunPower and the programming team during implementation to answer questions related to structural calculations and test the functionality of the tool 415.329.6100 XI T;o�i� www.maffei-structure.com ��1,48 Hermosa Avenue Oakland, CA 94618 MAFFEI STRUCTURAL ENGINEERING 11 August 2014 SunPower Invisimount Design Tool Structural Calculations Page 2 Performed independent calculations for six example project sites, plus spot checks of other potential project conditions, to compare to the structural design loads and load combinations calculated by the tool to act on the arrays, rails, and attachments to the roof structure. For all of the examples that we checked, the loads and load combinations calculated by the tool are consistent with our independent calculations in accordance with the structural design standard ASCE 7-10 Minimum Design Loads for Buildings and Other Structures. Performed independent calculations for ten example project sites, plus spot checks of other potential project conditions, to compare to the bill of materials estimated by the tool. For all of the examples that we checked, the quantities of parts estimated by the tool are the same as the quantities from our independent calculations, or within a reasonable tolerance. The attached "Engineering Basis of Calculations" describes the procedure that the tool uses for estimating the bill of materials. SUMMARY OF FINDINGS To an extent consistent with, the scope of our review, our professional opinion is that the Invisimount Design Tool calculates structural design loads on the solar arrays, and maximum allowable spacing of attachments to the roof structure, that are consistent with the standards and procedures described in the attached "Engineering Basis of Calculations," including ASCE 7-10 Minimum Design Loads for Buildings and Other Structures, the 2012 International Building Code, and the 2013 California Building Code. DESIGN RESPONSEWILITY The Invisimount Design Tool is intended to be used under the responsible charge of a registered design professional' where required by the authority having jurisdiction. In all cases, the tool should be used under the direction of a design professional with sufficient structural engineering knowledge and experience to be able to: Evaluate whether the tool is applicable to the project, based on the "Engineering Basis of Calculations" document and the characteristics of the project, and Understand and determine the appropriate values for all input parameters of the tool. Results of the tool should be checked against the design professional's judgment. Excerpts from standards such as ASCE 7-10 are presented in the tool as pointers to the standard and are not intended to diminish the user's responsibility to consult the applicable figures and sections of the standard directly. The user or design professional in responsible charge assumes full. design responsibility. The tool does not check the capacity of the building structure to support the loads imposed on the building by the array, such as bending strength of roof rafters spanning between supports.

Calculations are based on user input and the assumptions described below: The tool references the following sections of ASCE 7-10: • Wind loads are calculated per Section 30.4 "Part 1: Low -Rise Buildings" (not the Part 2 "Simplified" method). • Snow loads are calculated per Chapter 7. • Seismic loads are calculated per Chapter 13. The force Fp is applied horizontally in the down-slope direction, concurrently with the downward vertical force 0.2SDsWp. • Combinations of loads are calculated using "Strength Design" (LRFD) per Section 2.3. Procedure for determining attachment spacing Per ASCE 7-10 Figure 30.4-2, the tool calculates the dimension, a, of roof wind zones near roof edges, ridges, and comers, where design wind pressure is greater than in the middle of the roof. For each roof wind zone, the tool determines the maximum allowable spacing of attachments to resist the design loads, and the maximum allowable cantilever of a rail and module beyond the last attachment in a row. Spacing is based on the strength of structural components of the Invisimount system and the specified attachment type. Table 1 shows an example of spacing requirements calculated by the tool. Figure 1 illustrates the definition of attachment spacing and cantilever distance on a portion of an example array. • Bending strength of aluminum rails is calculated according to the Aluminum Design Manual 2010 Section B.3.2.1 (LRFD). • The strength of attachments to the roof is from product information provided by the attachment manufacturer. Where capacities are given by the manufacturer in terms of Allowable Stress Design (ASD) loads, allowable loads are multiplied by 1.5 for use with strength design (LRFD) load combinations. • The tool determines attachment spacing and estimates quantities for the attachments listed in the "attachment type" field. If other attachment hardware is used instead, you as the Registered Design Professional are responsible for determining the amount and spacing of attachments and verifying that the attachment hardware complies with building code requirements and with the Invisimount system. • The maximum allowable attachment spacing is calculated by checking demand/capacity ratios for bending in the rail and tension, compression, and shear on attachments for all considered load combinations. The reported maximum allowable spacing is the greatest spacing, rounded down to the nearest 3 -inch increment, for which all demand/capacity ratios are less than or equal to 1.0. • The maximum allowable cantilever of a rail beyond the last attachment in a row is taken as 1/3 the maximum allowable attachment spacing. • For attachment types that attach to rafters, the spacing selected for design is equal to the maximum allowable spacing, rounded down to a multiple of the rafter spacing. Spacing is limited to 6 ft. maximum. • The tool calculates loads on rails and attachments assuming that each module is installed centered over a pair of rails as in Figure 2(a). In cases where one rail is closer to the midpoint of the module as in Figure 2(b), for the final design of the array, you as the Registered Design Professional may need q ok ® Ll August,2014 I ' SunPower Invisimount Design Tool MAFFEStructural Calculations STRUCTURAL ENGINEERING Page 5, ,`'to perform additional calculations: to evaluate whether the spacing and: number of attachments calculated by the tool is adequate for the project condition. For example, for a uniformly -loaded module in Figure 2(b), Rail Y would have load increased by a factor of .(L — 2X)l(L X -1) compared to the condition in Figure 2(a). In this case, the user can override the quantity of attachments in the bill of materials if needed.

MMMMM MMMMM MMMMM MAHEI STRUCTURAL ENGINEERING Assumptions for use 11 August 2014 SunPower Invisimount Design Tool Structural Calculations Page 8 To streamline the use of the tool, the tool includes assumptions that are, appropriate for normal applications of Invisimount. Assumptions include the following: • The building is assigned to Risk Category H per ASCE 7-10 Table 1.5-1. Risk Category H covers most residential buildings. • No live load acts on the panels. • The wind directionality factor Ka = 0.85 per ASCE 7-10 Table 26.6-1. • ASCE 7-10 Figure 30.4-2A, 30.4-2B, or 30.4-2C is applicable for determining roof wind zones and external pressure coefficient GCp for solar the arrays. For one of these figures to be applicable, the height h must be less than or equal to 60 ft, and the building must be either a gable roof with slope less than or equal to 7 degrees, a gable/hip roof with slope 8 to 27 degrees, or a gable roof with slope 28 to 45 degrees. See ASCE 7-10 Section 30.4 for details. • For wind on solar arrays, the internal pressure coefficient GCS; = 0 per ASCE 7-10 Table 26.11-1. • For snow loads, the thermal factor C, = 1.2 for the array per ASCE 7-10 Table 7-3. This applies to "unheated and open air structures" and is assumed to be appropriate for solar arrays that are separated from the roof. • For snow loads, the exposure factor CQ = 0.9 for the array per ASCE 7-10 Table 7-2. This applies to roofs that are "fully exposed," meaning that there are no obstructions such as "terrain, higher structures, or trees," parapets, or other rooftop equipment of a height and proximity that would cause increased snow buildup on the array. The "fully exposed" assumption may not be appropriate for situations where obstructions are located "within a distance of 10h,," of the roof, "where ho is the height of the obstruction above the roof level. If the only obstructions are a few deciduous trees that are leafless in winter, the `fully exposed' category" is appropriate (ASCE 7-10 p. 30). See ASCE 7-10 Table 7-2 for details. • For snow loads, the slope factor CS for the array per ASCE 7-10 Figure 7-2 is calculated assuming the array is an "unobstructed slippery surface" that will allow snow to slide off the eaves. This assumption may not be appropriate for cases where snow is prevented. from sliding off the array because of valleys in the roof, for example. See ASCE 7-10 Section 7.4. • For seismic loads, Site Class = D per ASCE 7-10 Section 11.4.2. See ASCE 7-10 Section 11.4 for details and other site conditions. • The seismic component importance factor I,, = 1.0 for the solar array per ASCE 7-10 Section 13.1.3. • For seismic loads, the component response modification factor R,, = 1.5, and the component amplification factor ap = 1.0, per ASCE 7-10 Table 13.5-1 or 13.6-1. This assumption is consistent with recommendations for other types of rooftop solar arrays in the guideline SEAOC PV 1 Structural Seismic Requirements and Commentary for Rooftop Solar Photovoltaic Arrays.

Typically such buildings are residential with shingle or rile roofs. Each row or column of modules is supported by two rails, which are attached to the roof structure. The number and spacing of attachments to the roof structure can vary depending on, for example, structural loads at a particular site, the type of attachment hardware used, and spacing of the building rafters. The attached "Engineering Basis of Calculations" describes the scope of the Invisimount Design Tool, its calculation procedures, and assumptions for use. SCOPE OF OUR REVIEW Maffei Structural Engineering collaborated with SunPower on the development of the Invisimount Design Tool, including the following tasks related to structural calculations: • Provided documents describing applicable building code formulas and the calculation procedure to be implemented by SunPower's programming team • Worked with, SunPower and the programming team during implementation to answer questions related to structural calculations and test the functionality of the tool CoulI1TA' 415.329.6100 to www.mallei-structure.com a lei®'�'L+X77 148 Hermosa Avenue .( Oakland, CA 94618 MAFFEI STRUCTURAL ENGINEERING 11 August 2014 SunPower Invisimount Design Tool Structural Calculations Page 2 Performed independent calculations for six example project sites, plus spot checks of other potential project conditions, to compare to the structural design loads and load combinations calculated by the tool to act on the arrays, rails, and attachments to the roof structure. For all of the examples that we checked, the loads and load combinations calculated by the tool are consistent with our independent calculations in accordance with the structural design standard ASCE 7-10 Minimum Design Loads for Buildings and Other Structures. - Performed independent calculations for ten example project sites, plus spot checks of other potential project conditions, to compare to the bill of materials estimated by the tool. For all of the examples that we checked, the quantities of parts estimated by the tool are the same as the quantities from our independent calculations, or within a reasonable tolerance. The attached "Engineering Basis of Calculations" describes the procedure that the tool uses for estimating the bill of materials. SUMMARY OF FINDINGS To an extent consistent with the scope of our review, our professional opinion is that the Invisimount Design Tool calculates structural design loads on the solar arrays, and maximum allowable spacing of attachments to the roof structure, that are consistent with the standards and procedures described in the attached "Engineering Basis of Calculations," including ASCE 7-10 Minimum Design Loads for Buildings and Other Structures, the 2012 International Building Code, and the 2013 California Building Code. DESIGN RESPONSIBILITY The Invisimount Design Tool is intended to be used under the responsible charge of a registered design professional' where required by the authority having jurisdiction. In all cases, the tool should be used under the direction of a design professional with sufficient structural engineering knowledge and experience to be able to: • Evaluate whether the tool is applicable to the project, based on the "Engineering Basis of Calculations" document and the characteristics of the project, and • Understand and determine the appropriate values for all input parameters of the tool. Results of the tool should be checked against the design professional's judgment. Excerpts from standards such as ASCE 7-10 are presented in the tool as pointers to the standard and are not intended to diminish the user's responsibility to consult the applicable figures and sections of the standard directly. The user or design professional in responsible charge assumes full design responsibility. The tool does not check the capacity of the building structure to support the loads imposed on the building by the array, such as bending strength of roof rafters spanning between supports. This The terms registered design professional and registered design professional in responsible charge are defined in the 2012 IBC Section 202. D D MAFFEI STRUCTURAL ENGINEERING 11 August 2014 SunPower Invisimount Design Tool Structural Calculations Page 3 requires additional knowledge of the building and is outside the scope of the design tool and our review.

Calculations are based on user input and the assumptions described below. The tool references the following sections of ASCE 7-10: • Wind loads are calculated per Section 30.4 "Part 1: Low -Rise Buildings" (not the Part 2 "Simplified" method). • Snow loads are calculated per Chapter 7. • Seismic loads are calculated per Chapter 13. The force F. is applied horizontally in the down-slope direction, concurrently with the downward vertical force 0.2SDsW,,. • Combinations of loads are calculated using "Strength Design" (LRFD) per Section 2.3. Procedure for determining attachment spacing Per ASCE 7-10 Figure 30.4-2, the tool calculates the dimension, a, of roof wind zones near roof edges, ridges, and corners, where design wind pressure is greater than in the middle of the roof. For each roof wind zone, the tool determines the maximum allowable spacing of attachments to resist the design loads, and the maximum allowable cantilever of a rail and module beyond the last attachment in a row. Spacing is based on the strength of structural components of the Invisimount system and the specified attachment type. Table 1 shows an example of spacing requirements calculated by the tool. Figure 1 illustrates the definition of attachment spacing and cantilever distance on a portion of an example array. • Bending strength of aluminum rails is calculated according to the Aluminum Design Manual 2010 Section B.3.2.1 (LRFD). • The strength of attachments to the roof is from product information provided by the attachment manufacturer. Where capacities are given by the manufacturer in terms of Allowable Stress Design (ASD) loads, allowable loads are multiplied by 1.5 for use with strength design (LRFD) load combinations. • The tool determines attachment spacing and estimates quantities for the attachments listed in the "attachment type" field. If other attachment hardware is used instead, you as the Registered Design Professional are responsible for determining the amount and spacing of attachments and verifying that the attachment hardware complies with building code requirements and with the Invisimount system. • The maximum allowable attachment spacing is calculated by checking demand/capacity ratios for bending in the rail and tension, compression, and shear on attachments for all considered load combinations. The reported maximum allowable spacing is the greatest spacing, rounded down to the nearest 3 -inch increment, for which all demand/capacity ratios are less than or equal to 1.0. • The maximum allowable cantilever of a rail beyond the last attachment in a row is taken as 1/3 the maximum allowable attachment spacing. • For attachment types that attach to rafters, the spacing selected for design is equal to the maximum allowable spacing, rounded down to a multiple of the rafter spacing. Spacing is limited to 6 ft. maximum. • The tool calculates loads on rails and attachments assuming that each module is installed centered over a pair of rails as in Figure 2(a).

' For the purpose of estimating the number of attachments in a bill of materials, if any portion of a module ; is located in roof wind zone 2 or 3, the tool assumes that the attachment spacing for that entire in corresponds to the worst case wind zone. This' is a conservative assumption in order to simplify the: user interface of the tool and to avoid underestimating the number of required parts. For. the final design of the t array, you as the Registered Design Professional may choose ,to do more specific •calculations to. determine..whether fewer attachments can be used. For example, in the case of'a module where only one rail (and half or less of the, module area) is'in zone 2, with the remainder of the module in zone 1, it may . ` be appropriate to use zone 2 attachment spacing for the rail in zone 2, and zone 1 spacing for the rail in zone 1. In this case, the user can override the quantity of attachments in the bill of materials if desired:" MODULE, TYP RAIL, i ATTACHMENT, TYR x, r atvxxx:a, ? •c�x-an-rxt £t�tg- . - °" ii' 77 {° Y ROOF ROOF ROOF f� EDGEWIND, WIND ATTACHMENT SPACING ZONE I ZONE 1 ZONE 2 ONLY.ONE RAIL ,AND ' %: OF MODULE AREA a.

Assumptions include the following: • The building is assigned to Risk Category H per ASCE 7-10 Table 1.5-1. Risk Category H covers most residential buildings. • No live load acts on the panels. • The wind directionality factor Ka = 0.85 per ASCE 7-10 Table 26.6-1. • ASCE 7-10 Figure 30.4-2A, 30.4-2B, or 30.4-2C is applicable for determining roof wind zones and external pressure coefficient GCp for solar the arrays. For one of these figures to be applicable, the height h must be less than or equal to 60 ft, and the building must be either a gable roof with slope less than or equal to 7 degrees, a gable/hip roof with slope 8 to 27 degrees, or a gable roof with slope 28 to 45 degrees. See ASCE 7-10 Section 30.4 for details. • For wind on solar arrays, the internal pressure coefficient GCpi = 0 per ASCE 7-10 Table 26.11-1. • For snow loads, the thermal factor. C, = 1.2 for the array per ASCE 7-10 Table 7-3. This applies to "unheated and open air structures" and is assumed to be appropriate for solar arrays that are separated from the roof. • For snow loads, the exposure factor G = 0.9 for the array per ASCE 7-10 Table 7-2. This applies to roofs that are "fully exposed," meaning that there are no obstructions such as "terrain, higher structures, or trees," parapets, or other rooftop equipment of a height and proximity that would cause increased snow buildup on the array. The "fully exposed" assumption may not be appropriate for situations where obstructions are located "within a distance of 10ho" of the roof, "where ho is the height of the obstruction above the roof level. If the only obstructions are a few deciduous trees that are leafless in winter, the `fully exposed' category" is appropriate (ASCE 7-10 p. 30). See ASCE 7-10 Table 7-2 for details. • For snow loads, the slope factor CS for the array per ASCE 7-10 Figure 7-2 is calculated assuming the array is an "unobstructed slippery surface" that will allow snow to slide off the eaves. This assumption may not be appropriate for cases where snow is prevented from sliding off the array because of valleys in the roof, for example. See ASCE 7-10 Section 7.4. • For seismic loads, Site Class = D per ASCE 7-10 Section 11.4.2. See ASCE 7-10 Section 11.4 for details and other site conditions. • The seismic component importance factor Ip = 1.0 for the solar array per ASCE 7-10 Section 13.1.3. • For seismic loads, the component response modification factor R,, = 1.5, and the component amplification factor a,, = 1.0, per ASCE 7-10 Table 13.5-1 or 13.6-1. This assumption is consistent with recommendations for other types of rooftop solar arrays in the guideline SEAOC PV 1 Structural Seismic Requirements and Commentaryfor Rooftop Solar Photovoltaic Arrays.
