This existing structure is found to have adequate structural capacity to support all loads that are indicated below for this photovoltaic project. Location"R2"-2x12 spruce pine fir rafters spaced 16"on center.This existing structure is found to have adequate structural capacity to support all loads that are indicated below for this photovoltaic project. Roof Loading: - .3 psf solar dead load(modules plus mounting hardware) 10 psf roof materials dead load - 40 psf ground snow load Exposure category B, 117 mph basic wind speed,Veit This installation design will be in general conformance to the manufacturer's specifications,and complies with all applicable laws,codes,ordinances,and the MA Residential Building Code 780 CMR 9th Edition. The spacing and fastening of the mounting brackets is to have a maximum of 48"o.c. span between mounting brackets and secured using 5/16"diameter corrosive resistant steel lag bolts.To evenly distribute the load across the roof rafters,there shall be a minimum of(2)mounting brackets per rafter and a minimum 3"penetration of lag bolt per bracket, which is adequate to resist all wind live loads including wind shear/uplift.Per NDS section 12.1.4,a 7/32" diameter lead hole shall be bored into the framing member to the same depth of penetration as the threaded shank of the lag to avoid splitting of the rafter.Attached on the next page is the solar layout plan for your file.

In this application note,we will discuss one particular aspect of the Equinox system—integrated equipment grounding through the use of Listed Equinox components. Specifically,we will provide: • . An overview of the equipment grounding solution incorporated into each Equinox system • A discussion of common questions and concerns relevant to the National Electric Code and electrical inspections • Guidance on interpretation of the relevant Listing materials By following the guidance in this application note,you will have even more confidence building code-compliant SunPower Equinox systems the way they were designed and engineered,and be fully empowered to educate Allis and inspectors on the benefits of its Listed grounding solution. References • NFPA 70:2014 National Electric Code("the Code") Unless otherwise indicated in the text,ail Code references are from the 2014 National Electric Code. • NFPA 70:2017 National Electric Code. • Analysis of Changes, NEC 2017. Document#518101 RevD 139 SunPower Proprietary Equinox Integration Features and Design Benefits SunPower Equinox has been designed and engineered to be an integrated solar power system. Key components include AC modules,AC module extension cables and accessories, InvisiMount"" mounting hardware,and EnergyLinkTM monitoring hardware. In the context of this Application Note's discussion about equipment grounding,"integrated"means SunPower AC modules are engineered and Listed to work with SunPower AC module extension cables and InvisiMount mounting hardware. There are clear benefits to an integrated system for installers and Ails,including: 9. Use of components exclusively Listed and identified for the specific purpose 2. All components sourced from a single supplier 3. Factory integration 4. 100%end-of-line factory testing 5.. Easier installation,with fewer opportunities for mechanical failure or installation error 6. Fewer specialized skills required for installation 7. Easier inspection phase due to clear installation instructions and fewer opportunities for field modification All of this adds up to a solution that enables installers and Ails to have increased confidence in the quality of installation and the integrity of the ground solution-all while reducing the number of components and installation steps. There are several aspects to this integration:the frame of SunPower's AC module includes an external flange that is designed to be captured and penetrated by the teeth of the InvisiMount mid clamp.And the AC module cables include just three conductors:two ungrounded conductors and an equipment grounding conductor; unlike the output of most inverters,SunPower AC modules are designed and Listed to operate without a neutral. A key aspect of this integration is equipment grounding.All of the rooftop hardware components are designed to electrically bond the non-current-carrying components of the system to each other. Every component in this electrical bonding system includes features that complete the bond,and which are Listed to perform their function. The diagram on page 5 summarizes the components of the Equinox system and how they are bonded to each other.The third and fourth columns in the diagram's table reference relevant Code and listing considerations. Ultimately the system is connected to ground(permanent earth or building ground),so well start from there and work our way up to the array components: Document#518101 RevD 140 SunPower Proprietary 1. Grounding Electrode&Grounding Electrode Conductor(GEC): For most residential installations,a grounding electrode and GEC is already installed. Most AHJ's require the installer to verify that the grounding electrode is adequate for all services and equipment at the site. Generally, all grounding electrodes must be bonded together and all household equipment must be bonded together, and the equipment and grounding electrodes are connected by a single conductor—the GEC. If the existing grounding electrode and GEC are adequate,no further grounding work by the solar system installer is necessary. 2. Equipment Grounding Conductor(EGC):This is a field-installed conductor that must be installed along with the AC module output-circuits.Typically it will originate at the grounding busbar or terminal block in the main service panel. It should be routed with the power circuits in the same raceway, conduit, or cable.The conductor should be installed according to NEC 690.43 and sized based on 690.45. For most AC module circuits,this means the EGC will be a minimum of 12 AWG(although it is not uncommon to use 10 AWG). 3. Rooftop Junction Box to AC Module Extension Cable: The EGC originating at the service panel must be connected to the EGC originating at the array, and its connection completes the electrical bond between the metallic frames and non-current-carrying hardware on the roof and on the ground. This connection is typically made inside an attic or a rooftop junction box.The Listed SunPower AC module cable(integrated into the module at the factory;as well as the standalone AC extension cables)include a 12 AWG equipment grounding conductor.The installer connects the EGC in the cable to the EGC from the service panel using a Listed device (such as a IDEAL's Buchanan®crimp hardware, or the grounding busbar inside a SolaDeck°"junction box). 4. AC Module Extension Cable to AC Module Microinverter(MI): The Listed AC module cable carries the equipment ground to grounding terminal inside the MI.The AC module extension cables are Listed and specifically identified for use with SunPower AC modules. The MI is a part of the Listed AC module. 5. Ml to AC Module Frame:The MI is bonded to the module frame in the factory. This is part of the product Listing, and the product is tested for all dead metal parts of the AC module (including the frame and the Ml)to be grounded through the ground wire in the AC module extension cable. 6., AC Module Cable to AC Module Cable: The AC module cable not only connects the EGC originating at the service panel to the first AC module—it also carries the equipment ground from module to module. This is not only very helpful because it eliminates the need for any external equipment grounding, it is also required by 690.31(D). Document#518101 RevD 141 SunPower Proprietary 7. AC Module Frame to InvisiMount Rail Using Mid Clamps:Adjacent AC modules are mounted to the rail in an Equinox system using InvisiMount mid clamps.These mid clamps are part of the Listed InvisiMount mounting system, and they include teeth which not only secure the module in place, but also bite through the anodized coating on both the external flange of the module frame and rail to create a durable,high-quality electrical bond. InvisiMount rails and mid clamps have been evaluated by UL specifically for bonding the AC module frame to the rail. 8. AC Module Frame to InvisiMount Rail Using End Clamps: Nonadjacent modules(such as the last module in a row)are mounted to the rail using InvisiMount end clamps. Like the mid clamps,end clamps have been evaluated for bonding the rail to frame.The end clamp includes two stainless steel pins that penetrate the anodized coating of the module frame and rail to complete the bond. 9. Rail-to-Rail Splice:Adjacent sections of InvisiMount rail are connected together using rail splices and splice screws.The InvisiMount splice attaches to the rail by installing the screws into the pre-drilled holes in the splice and the rail ends,thereby both securing and bonding the rail and splice bar to each other.The splice and screws are part of the product Listing and have been evaluated for bonding rail sections together.

(It is typically only in the case of a ground-mounted system or a home that has an inadequate existing grounding system that additional grounding electrodes or new grounding electrode conductors are required). But this approach is relatively new and still unfamiliar to many designers, installers,and AHJs, hence commonly asked questions include: • Does the Code allow for an integrated grounding system? • Does the Code also require an external grounding system or components in AC module systems? • What are the disadvantages to external grounding components? • Shouldn't SunPower Equinox require an auxiliary grounding electrode and GEC? Let's take a closer look at each of these questions. • Does the Code allow for an integrated grounding system? Yes, in fact the Code requires an integrated grounding system for AC modules. SunPower AC modules use type TC-ER cables for connections between AC modules and from the AC modules to the field-installed cables or conductors. This cable includes one black, one red, and one green 12 AWG conductor. The Code specifically allows for TC-ER cables to be used: 690.31(0)Multiconductor Cable. Multiconductor cable Type TC-ER or Type USE-2 shall be permitted in outdoor locations in PV inverter output circuits where used with utility interactive inverters mounted in locations that are not readily accessible.The cable shall be secured at intervals not exceeding 1.8 m(6'). Equipment grounding for the utilization equipment shall be provided by an equipment grounding conductor within the cable. We should also keep in mind that an AC module is effectively an inverter output circuit (690.6(B)), and that rooftop-mounted AC modules are typically not readily accessible, so 690.31(D)requires that equipment grounding for the modules be accomplished by using the equipment grounding conductor within the cable. In this sense,grounding an AC module is very similar to grounding a consumer appliance such as a refrigerator: by plugging the AC module into a circuit having an equipment grounding conductor, the AC module is grounded. Document#518101 RevD 144 SunPower Proprietary • • Does the Code also require an external grounding system or components in AC module systems? No,for residential rooftop AC system installations there is nothing in the Code that would require the use of external grounding components such as lugs or copper wire. This question boils down to this:does the equipment grounding solution integrated into every Equinox system meet the equipment grounding requirements of 690.41 through 690.49? We can address each of these provisions in turn: o 690.41 does not apply to AC modules.This section applies to the grounding of DC circuits(e.g.,positively grounded PV systems).As such,it applies to photovoltaic source circuits or photovoltaic output circuits. Per 690.6,the output of an AC module is an inverter output circuit and the requirements of 690 that pertain to photovoltaic source circuits or output circuits do therefore not apply to AC modules. o 690.42 does not apply to AC modules for the same reasons 690.41 does not. o 690.43-SunPower Equinox fully complies with the relevant portions of 690.43: • 690.43(A)-SunPower Equinox is grounded when installed according to the instructions and connected to an equipment grounding conductor bonded to the premises grounding electrode system. • 690.43(B)-SunPower Equinox requires the installation of an equipment grounding conductor between the array and other equipment(typically originating at the rooftop junction box and terminating at the grounding busbar or terminal in the main service panel). • 690.43(C)- InvisiMount end clamps and mid clamps are Listed and identified for bonding module frames to rails. • 690.43(D)- InvisiMount end clamps and mid clamps are Listed and identified for bonding module frames to rails, • 690.43(E)-InvisiMount mid clamps are identified for the purpose of grounding modules: • 690.43(F) The integrated AC module cable and AC module extension cables do include an equipment grounding conductor.Installers shall ensure that field-installed cables or conductors in raceways also contain the equipment grounding conductor along with the other circuit conductors. Document#518101 RevD 145 SunPower Proprietary c. 690.45-SunPower Equinox meets this requirement by including a 12 AWG equipment grounding conductor.The EGC in every AC module cable is 12 AWG.The maximum overcurrent protection for an AC module circuit is 20 A.The minimum EGC size based on the table at 250.122 is 12 AWG. If multiple circuits are routed with a single EGC for the array,250.122(C)allows the installer to use 12 AWG for the combined EGC. o 690.46 does not apply to SunPower Equinox.It modifies 690.45 by requiring a larger conductor when the EGC is not routed with circuit conductors and installed outside of a raceway. But SunPower Equinox does comply with 690.31(D)which requires that the EGC be contained within the cable assembly.690.46 was inserted into the Code to prevent installers from using small conductors such as 14,12,or 10 AWG to ground rails in systems having no integrated grounding. 690.47(A)does not apply to SunPower Equinox.Installing AC modules constitutes the installation of new"equipment'on an existing AC system.As such,the existing system already has a grounding electrode system,and the only requirement is to connect the new equipment to that system. c. 690.47(B)does not apply to SunPower Equinox.This section pertains only to DC systems in which a photovoltaic source circuit would be either grounded or ungrounded; but 690.6 exempts AC modules from requirements pertaining to photovoltaic source circuits. 690.47(C)does not apply to SunPower Equinox for the same reasons that 690.47(A) and 690.47(B)do not apply. c 690.47(D)does not apply to SunPower Equinox on residential rooftops where there is an existing adequate premises grounding electrode system.This will be discussed in detail later in this App Note, but in most cases(99%),the premises wiring electrode eliminates the need for an additional array grounding electrode(Exception No.2)and the equipment grounding conductor connected to the grounding busbar or terminal in the main service panel is sufficient for connecting the metallic surfaces of the array to ground. c 690.48.When an AC module is removed from a SunPower Equinox system,it interrupts the circuit and equipment grounding connection between modules.This can leave the equipment ungrounded if it is not returned to service. Upon a module's removal,the modules downstream of the removed module are reconnected using an AC module extension cable to bridge the gap,which reestablishes the equipment grounding connection. 690.49 does not apply to SunPower Equinox because it refers to photovoltaic source and output circuit grounded conductors. 690.50 does not apply to SunPower Equinox because equipment bonding jumpers are not used. Document#518101 RevD 146 SunPower Proprietary Returning to the original question,"Does the Code require any external grounding for SunPower Equinox?'we can see that when installed in accordance with the manufacturers instructions,other than a properly sized and installed EGC originating at the array junction box and terminating at the main service panel, no additional grounding components are required. • What are the disadvantages to external grounding components? Yes,external grounding components are subject to damage and corrosion,must be properly installed(sometimes using specialized tools and components),and must be properly specified including verifying the proper size,type,identification,and Listing.All of this adds up to opportunities for the external grounding components to be less effective than integrated grounding components. With SunPower Equinox,the EGC is sized appropriately;protected by the cable sheath and insulation; 100%end-of-line factory tested; and part of the product Listing. Metallic hardware in the system is bonded using components Listed and identified to work together and requires no specialized skills or tools to complete either mechanical or bonding connections.Completing grounding connections is as simple as tightening a mounting bolt or connecting a plug to a receptacle. With external grounding components,the All must verify that the EGC is sized appropriately,and that it's upsized when installed separately from circuit conductors on the rooftop.EGCs must be connected to lugs that are Listed and identified for the purpose and suitable for the environment. Set screws or terminations must be installed correctly and tightened properly. Exposed copper must be isolated from other metals.This adds up to numerous opportunities for failure that in addition are difficult to detect or inspect.And even if the installation is completed properly,there is ample evidence that exposed ground lugs and exposed copper wire may not provide effective equipment grounding for the life of the system in some environments. In short,exposed copper and external ground lugs are not more effective than the SunPower Equinox internal grounding system—hence all of its achieved Listings and certifications. • Shouldn't SunPower Equinox require an auxiliary grounding electrode and GEC? Because 690.47(D)does not apply to SunPower Equinox on residential rooftops where there is an existing adequate premises grounding electrode system,this simply leaves the question of how to connect the array to the premises wiring electrode. This section has been the subject of much controversy and misunderstanding in recent years, but the intention of this section is simply stated: The array must be connected to a grounding electrode located at the structure that supports the array. Document#518101 RevD 147 SunPower Proprietary • For a ground-mounted array,this might require the installation of new grounding electrodes unless the ground structure meets the requirements of 250.52.But the vast majority of residential rooftop arrays can use the existing premises wiring electrode.So how do we interpret the phrase,"as close as practicable to the location of roof-mounted PV arrays"?This phrase would simply apply to a structure that does not have an existing grounding electrode (such as a shed or barn). The fact that a new grounding electrode and an associated grounding electrode conductor are not required for a residential rooftop array with an adequate premises grounding electrode system is illustrated in two ways: The new 690.47(A)clarifies the requirements for a structure to have a grounding electrode. 690.47(B)makes a grounding electrode and grounding electrode conductor optional,but not mandatory: 690.47(B)Additional Auxiliary Electrodes for Array Grounding.Grounding electrodes shall be permitted to be installed in accordance with 250.52 and 250.54 at the location of ground-and roof-mounted PV arrays.The electrodes shall be permitted to be connected directly to the array frame(s)or structure.The grounding electrode conductor shall be sized according to 250.66.The structure of a ground-mounted PV array shall be permitted to be considered a grounding electrode if it meets the requirements of 250.52. Roof mounted PV arrays shall be permitted to use the metal frame of a building or structure if the requirements of 250.52(AX2)are met. The intention of the 2014 Code and the explicit changes to the 2017 Code are further illustrated by IAEI's Analysis of Changes, NEC 2017(emphasis added): ...The provisions of 690.47(D)[now 690.47(B)]pertaining to additional auxiliary electrodes for PV array grounding have been revised to clarify that auxiliary electrodes are permitted but not required.For most PV systems installed on a rooftop,the large quantity of conductive metal increases the likelihood of a lightning strike.An auxiliary grounding electrode system would help to minimize the effects of such a lightning strike.The primary purpose of an auxiliary grounding electrode is to maintain the frames of the PV array to as close to local earth voltage potential as possible. This potential con also be achieved through a properly installed equipment grounding conductor back to an established grounding electrode system for the building or structure.As indicated by the language of 250.54 for auxiliary grounding electrodes,the additional grounding electrodes are permitted to be installed but are never a requirement as implied by the previous language at 690.47(D)and in the 2014 NEC. Note in particular the language that states the intention of an auxiliary grounding electrode can be achieved through a properly installed EGC back to the premises grounding electrode. SunPower Equinox meets this intention for rooftop arrays by using the integrated grounding system along with a properly sized and installed EGC. Document#518101 RevD 148 SunPower Proprietary Use and Interpretation of Listing Materials Innumerous locations,the Code requires that PV equipment be Listed and identified for the use. In this context,"listed"and"identified"have the same meanings in the Code.SunPower Equinox components have been Listed by UL,and have been specifically tested and are recognized by UL to perform certain functions identified in the Listing reports. Additionally,the Code requires that Listed equipment be installed and used in accordance with instructions included in the Listing or labeling.This means that SunPower Equinox must be installed in accordance with the AC Module Safety and Installation Instructions,and the SunPower Equinox lnstollation Guide. Each of these documents includes instructions that are part of the Listing. The following is a list of key Listing documents and some notes on their interpretation with regard to grounding SunPower Equinox: • Certificate of Compliance-AC Modules.This is the proof of Listing for AC modules to UL 1741.The SunPower AC module product includes a Listed PV Module(UL 1703)and a Listed Microinverter MI 1741), integrated at the factory.The Listing Report includes evaluation of the bond between the MI and AC module frame and states the requirement that AC modules shall be grounded using the integrated equipment grounding conductor. It identifies SunPower AC module extension cables as being the sole acceptable wiring between modules. • Certificate of Compliance- SunPower Microinverter.This is the proof of Listing for the SunPower microinverter incorporated in the AC module to UL 1741.While technically a subcomponent of the Listed AC module,this is provided as evidence of the evaluation of the bond between the AC module cable and MI chassis and states the requirement that the MI shall be grounded using the integrated equipment grounding conductor. It identifies SunPower AC module extension cables as being the sole acceptable wiring between modules. • Certificate of Compliance-AC Module Cables.This is the proof of Listing for AC module cables to UL 9703 - Standard for Distributed Generation Wiring Harnesses.This listing is for the models identified in the AC module and MI Listings. It specifies the internal wiring of the AC module extension cable and includes evaluation of the grounding connection. • Certificate of Compliance InvisiMount.This is the proof of Listing for InvisiMount to UL 2703,including evaluation for structural integrity,grounding,and fire classification.The Listing Report includes evaluation of the bond between SunPower G5 module frames(the frames used on SunPower AC modules)and InvisiMount rails using mid damps and end clamps;between L•feet and the rails;and between adjacent rail sections using the InvisiMount splice. Document#518101 RevD 149 SunPower Proprietary • Certificate of Compliance-PV Module.This is the proof of Listing for the SunPower PV. modules that are incorporated into the AC module to UL 1703.This includes identification of InvisiMount as an acceptable means of grounding and bonding. • SunPower AC Module Safety and Installation Instructions. These instructions are part of the Listing for AC modules. In Section 4.1 they state that SunPower AC modules shall be grounded using the integrated grounding and that no external or additional connection to the AC module is required.It further states that grounding of mounting rails and other components is achieved through the proper installation of InvisiMount. • SunPower Equinox Installation Guide. These instructions are part of the Listing for InvisiMount and for SunPower AC modules. In Section 4 there's a detailed description of the integrated equipment grounding solution and installation instructions for InvisiMount components required to complete the grounding connection. Summary SunPower Equinox includes an integrated equipment grounding solution that is easy to install and easy to verify.Equinox offers substantial benefits over external equipment grounding solutions. Integrated grounding for AC modules is not only a benefit for installers(it is easier and faster to install),and:AHjs(it is easier to inspect and verify proper installation)-it is required by the Code. The integrated grounding solution incorporated into SunPower Equinox is 100%end-of-line tested and Listed by UL.This consolidated information in this App Note will satisfy even the most diligent and pickiest of AH)s.
