In recent years the issue of PV system bonding and. grounding has received .increased attention in North America from standards issuing bodies such as Undeivuriters Laboratories (UL), the National Fire Protection Association WPA) through the National Electfi-cal Code (NEC) and various Authorities Having lurisdicti:on (AH1). After issuing *Standard 1703 which, among other things, requires and tests for suitable connection of PV module frames to ground, UL has focused on the electrical bonding of the framework which supports the PV modules. This bonding includes electrically bonding the module frames to the support structure and the bonding of the various components of the racking structure to each other to forma single, continuously electrically bonded structure which can then be connected" to the system grounding electrode. Module bonding laHn lugs Because most PV mounting systems are constructed of mill -finish aluminum while most• PV module frames are anodized, the task of connecting the aluminum frame of the module to the mounting system has traditionally been cumbersome and expensive; The anodized layer on the module frame is essentially non-conductive and forms an insulating barrier between the frame and other elements of the mounting system. The nearly .universally accepted method of connecting or bonding ,the. module frame to the mounting system is via use of lay -in lugs (Figure 4) certified to UL Standard 467 as being suitable for .system bonding and grounding as specified in the NEC. These lugs are readily'�ava Table from various vendors. Figure la. Typical lay in lug kNut �_ sam1wWaWw '� MO&de from j � LAV -in lug I inAs Ral wastm A6er*e scmw Figure lb.

The serrated or star -washers _j pierce the anodized coating on the module and make contact with the conductive aluminum 'frame. A suitably sized copper wire is then inserted. and fastened in the•lug and connected to. the system grounding point. , Cay -in are expensive to purchase and time-consuming to install. Mounting Systems, Inc. has developed instead, an integral bonding system. Which eliminates the need for lay -in lugs , and ottier third party devices.,' Alpha' Clickstone bonding *.The Alpha' ickstone PV -mounting system provides an integrated bonding system comprised of Cl specially designed clamp bodies, -rail latching and threaded connections'. r 'There are two versions of rthe Alpha' clamp bodies. Pre -production and early production vetsions.of the Alpha' bonding_•clam.p employ stainless steel, cone point set screws (Figure 2) mounted in ti;e clamp body. After the clamp is secured on the modules, the set screws are tightened so that #tie points on the set screws pierce the anodized module coating and bond the, module frame to the clamp;body through the set screw threads'. Figure 2, Early production version clamp body with set screws Standard production versions of the bonding clamp use a proprietary, stainless steel bonding + , plate (Figure 3) preassembled on the Clickstone. The ' bonding plate -is formed with angled bonding teeth at each end. Bonding teeth r. Figure 3. Bonding plate - r Per U1 Subject 2703 Ed.2, Section 9.4, two or more threads in contact with the threaded body constitutes w an acceptable electrical bond. ` . mounting systems The plate is preassembled to the Alpha` clamp below the clamp body as shown in Figure 4. When the clamp is tightened into place on the module frame the teeth pierce both the anodized coating on the module and the oxide or anodized coating on the clamp body, thus forming an electrical path between the module frame and the clamp body. An external -tooth star washer' between the Clickstone bolt head and the clamp body serves to electrically bond the clamp body, bonding plate and module to the Clickstone bolt which threads into the actual Clickstone, itself. I Clamp body 2 Bonding plate 3 Clickstone bolt Figure 4a. Bonding plate assembled to bolt Figure 4b. Clickstone bolt assembly The Clickstone (Figure 5) anchors the module and clamp.to the Alpha' rail and plays an integral role in the system bonding. As shown in Figure 5, specially designed, sharp ridges on the latching mechanism of the Clickstone engage complementary, sharp ridges in the rail channel. As the clamp bolt is tightened, the latching teeth engage the rail channel ridges, crushing or piercing the oxide or anodized layers on each component to the base aluminum. This creates a solid, high-ampacity electrical connection. As the bolt is tightened to the recommended torque setting specified in the Alpha' Installation Manual (15 ft -lbs / 20 N -m), the complementary shapes of the Clickstone and rail channel form a seal, preventing further oxidation and ensuring a reliable electrical bond between the modules, clamp components and the rail. Bonding ridges Figure 5. Clickstone and rail ' Per UL Subject 2703 Ed.2, Section 9.4. A bolted, screwed or riveted connection that incorporates a star washer under the head of the fastener, a serrated screw head, or a bonding device between surfaces may be acceptable for penetrating nonconductive coatings. frio ntiPlg t' ; ^ systems ` -.

Alpha` bonding path Rail-to=Rail Bondingh of It is often the:case that module mounting rails are spliced together to form a longer lengt. ,. rail. The Mounting Systems Alpha' system uses a dedicated 'rail splice (Figure -7) for this purpose • Rail splice Splice shown connected to one rail , - Figuxe'-7 Alpha'- rail splice mounting systems The Alpha' splice, is comprised of the aluminum splice body, stainless steel bolts, stainless steel square nuts and stainless steel, external -tooth star washers as shown in Figure 8. Figure B. Alpha' rail splice components When the rails to be connected are inserted into the splice and the bolts are tightened to the torque recommendation in the Alpha' Installation Manual, the bolts pierce the oxide or anodized layer on the rails and create an electrical bonding path to the bolts. These bolts then connect through the square nut threads, to the star washers and then to the splice body, thus providing a conductive path through the body of the splice and electrically bonding the entire assembly as shown by the green line in Figure B. No additional, external bonding devices are required. Rail -Roof attachment bonding Alpha` rails are connected to the roof attachments (L -feet or various the roof hooks) by means of stainless steel hammer -head bolts and serrated nuts as shown in Figure 9. When properly tightened, the pressure on the bolt head is sufficient to break through the oxide or anodizing on the rail and form an electrical connection from the rail, through the bolt shaft to the serrated nut and then to the roof attachment device. .caw.—r4 mounting systems System grounding The combination of the Alpha' Clickstone clamp assembly, rail splices and roof attachment, devices provides a completely bonded PV structure. Grounding this bonded structure may be accomplished using approved lay -in lugs or other devices. Mounting Systems, Inc. recommends the use of Burndy WEEB=Lugs specifically intended for use on Alpha' rails. These preassembled lugs are available from Mounting Systems (Part Number 720-1235 [set of 4]). The WEEB-lug can be installed in'any of the three channels in the Alpha* rail. A UL listed bonding washer on the lug bonds the lug to the Alpha' rail. A suitably sized conductor can then be connected to the WEEB-Lug for connection to the system ground electrode. UL Subject 2103 Ed. 2 Compliance By virtue of the bonding methods described above, the Mounting Systems, Inc. Alpha' PV mounting system .is fully compliant with UL Subject 2703 Ed. 23. Extensive testing on key bonding components of the Alpha' system has been performed. Testing was carried out in excess of and under more rigorous conditions than required by UL Subject 2703 Ed. 2 as it is presently written. The system meets or exceeds all pertinent requirements. When assembled and installed per the instructions provided in the Mounting Systems, Inc. Alpha' Installation Manual and/or with appropriate use of third -party devices in compliance with instructions in their respective installation manuals or instructions, the Mounting Systems, Inc.. Alpha' system will be fully and securely bonded electrically and can be grounded by approved methods.
