2.0 Safety

••Do not twist the module frame.

Ensure to follow all safety guidelines stated below. Failure to do so can cause injury, damages, or a void in the module warranty.

••Do not stand, step, walk or jump on the module. ••Do not mark the modules with sharp instruments. ••Do not leave a module unsupported or unsecured. ••Do not modify module in any way, which includes the frame, glass, eva, etc.

2.1  General Safety ••Modules are intended for outdoor use. ••Do not submerge modules in water at any time. ••The front and back of each module is labeled with a product bar code. Do not cover, remove or deface labels as they are necessary for product identification. ••Do not allow unauthorized persons near the installation site or module storage area. ••Troubleshooting should include planning, checking, disconnecting, cause seeking, replacement and record keeping. ••Do not wear rings, jewelry, watches or other metallic items while working with photovoltaic modules.

2.2  Mechanical Safety ••Damage to the glass surface or its anti-reflective coating will impact the power output and overall efficiency of the system. Scratches, handling marks or any other damage to the glass surface must be avoided. ••To avoid these and other performance prohibitive issues, keep the front side of the module clean and free of obstructions including covers, tape, adhesives, paint and debris. ••Packaged modules must be stored indoors; in a dry and ventilated area. ••Once opened, continue to store modules in a dry and ventilated room. ••To safely keep modules stored, they must remain packaged on the provided pallets, and must not be stacked more than two pallets high. ••Do not place or drop objects on the modules, including other modules.

••Upon unpacking, only carry a module by its frame with two or more people. Do not carry a module by the wires or junction box. ••All modules are manufactured with a sealed junction box, pre-attached cables and locking connectors. These components should not be modified or tampered with in any way. If connectors are not hooked up right away, SunEdison recommends attaching protective caps to prevent damage to the connectors. ••Do not install or handle the modules or their components when they are wet or during periods of high wind. ••Do not attempt to disassemble, repair or open any part of the module; including the junction box or sub-components. ••Do not artificially concentrate sunlight on a module. ••Do not install or handle broken modules. If a module is broken, or the back sheet is torn, contact with the surface or frame can cause an electrical shock.

2.3  Electrical Safety ••All installations must be performed in compliance with all applicable regional and local electrical codes or other applicable national and international electrical standards. ••Use only insulated tools during installation, troubleshooting and maintenance of the modules. ••Wear suitable protection to prevent direct contact with module’s electrical output and mechanical sharp edges. ••Cover the front of the modules with an opaque material to stop production of electricity when installing or working with a module or wiring.

WARNING: Precautions should be taken to avoid damage to the glass surface when unpacking, handling or storing the modules since any damage to the glass surface may impact the power output of the modules.

F-SERIES and R-SERIES  72-Cell Installation Guide ••Modules connected in a series should not be disconnected under illumination. Disconnecting modules under illumination may cause electrical arcing, which may result in burns, fires or other injuries and damages. ••Photovoltaic modules produce DC electrical energy from sunlight. When illuminated, each module can have a DC potential of over 45 V and should be handled with care. ••Always use a wire management system that keeps wires and cables out of direct contact with edged surfaces, which could cut or damage the insulation. Do not allow wires to rest on the ground or roof surface.

3.0  Mechanical Installation 3.1  Planning and Design ••Before installation, check to ensure the sub-structure will accommodate expected system loads. This includes and is not limited to roof, foundations, mechanical structure and mechanical connections. ••All Silvantis solar modules have a module fire resistance rating of Class C. According to the UL1703 test protocol, revised in 2014, all Silvantis solar modules also have a module fire resistance rating of Class A for spread of flame, and fire performance of either Type 1 or Type 2 classification as specified on the module label. Per UL, the fire rating of this module is valid only when mounted in the manner specified in the mechanical mounting instructions. The system fire rating is determined by the module, rack and roofing materials. SunEdison recommends not mixing module fire performance type within a system. ••Mechanical structures should not contact the module back sheet, any racking or the microinverter under any expected load conditions. ••Consider the following factors during system design, which will influence performance:

4



a. SunEdison solar modules produce the most power when they are pointed directly at the sun, and should be tilted for optimum system performance.



b. Proximity to obstructions have the potential to shade or damage the modules (examples below): • walls • buildings • trees • groundcover • snow cover • dust and debris



c. Designs should allow adequate airflow across the back of the module because elevated temperatures will decrease energy yield.



d. Allow a minimum spacing of 10 mm between modules for thermal expansion.

3.2  Module Installation Options For bolt and clamp mounting locations and allowable load capacities, please refer to the table on pages 6-7. ••Each module should be mounted using four bolts through the mounting holes on the rear side of the module, or with four clamps over the front side, within the region specified as shown in the mounting diagram below. ••Depending on the desired load capability of the array, modules may be mounted either perpendicular or parallel to the structure rails. Clamps can be mounted anywhere inside of the safe mounting range for each case illustrated in the table on pages 6-7. ••If using bolts, use a bolt stack no smaller than ¼"-20 or M6, with two flat washers and a locking washer as shown in Appendix 7.1. ••To ensure an adequate clamping area, all clamps must be able to clamp within the range specified in the table on pages 6-7. All fasteners used to fix the modules with clamps should be no smaller than ¼”-20 or M6.

3.3  Module Installation Using Center Mounting Brackets ••Modules may also be mounted using center clamps as shown in Appendix 7.2, for use with trackers. ••Center mounting clamps must meet SunEdison approved extrusion and hardware requirements. ••For module loads higher than 2400 Pa, module clamps and hardware must be pre-approved by SunEdison. ••SunEdison approved center clamps utilizing M8 bolts are to be tightened to 9.2-11.9 N·m (6.8-8.8 ft·lbs). ••Mechanical structures should not contact the module backsheet under any expected load conditions. ••Ensure that frame weep holes (see Appendix 7.1) are not obstructed by the mechanical installation. ••Mechanical installation of the module shall not cause the frame to torque more than 38 mm. ••A minimum clearance of 152 mm is required between the roof and bottom of the module frame.

••To provide adequate fixing or clamping force, torque the fasteners to the manufacturers torque specifications. ••For all cases, the area of the supporting structure in contact with rear side of the module must comply with the dimensions specified in Appendix 7.1. ••All other structural dimensions, such as clamp and rail thickness, should be sized appropriately for the intended site load.

F-SERIES and R-SERIES  72-Cell Installation Guide 4.0  Electrical Installation

4.2  Module Wiring

4.1  Planning and Design All modules are manufactured with a sealed junction box, pre-attached cables and locking connectors. These components should not be modified or tampered with in any way. Note: Installers shall ensure that the polarized locking connectors are from the same supplier. Do not mix polarized interlocking connectors from different manufacturers—including connections at the inverter, combiner boxes and modules. Doing so will void the warranty. Refer to the corresponding data sheet for connector types.

••The module includes wires and polarized locking connectors from the junction box on the back of the module. Field replacement of connectors or cables must be avoided and will void the product warranty. Polarized locking connectors of the same type, make and manufacturer are required for all series string wiring. The maximum operating temperature of the wires and connectors should not exceed 85 C. ••When installing modules in landscape orientation, use the 1.3 meter lead lengths to ensure enough cable length to make adjacent module-to-module string connections (assumes a maximum spacing of 50 mm between adjacent modules). ••Always wire modules so that proper polarity is maintained. Avoid placing excessive tension on the cables.

••Ensure connectors are clean and dry before establishing connection. ••Ensure that all wire, fusing and disconnects are appropriately sized for the system design according to national, regional, and local codes. ••Electrical characteristics are within plus or minus 5% of rated values for Isc, Voc, Impp and Vmp. Pmax ranges between 0% to +3% (R-Series) and 0 W to +5 W (F-Series) of rated Pmax at standard test conditions (STC). However, modules will operate under conditions that may be significantly different than STC. SunEdison suggests multiplying specified ratings by a minimum of 1.25 or more when designing the system and balance of system components. Refer to local codes before planning and designing the system. ••Determine the maximum number of modules that may be connected in series using the following formula Ns = Vmaxs/Vocm

••There is no limit to the maximum number of series strings that can be combined in parallel. However, each string must include overcurrent protection with a maximum rating of 15 A. SunEdison recommends the use of DC rated fuses or overcurrent protection devices with the appropriate maximum voltage rating. ••Do not connect modules directly to a parallel bus. ••The cross-sectional areas of cable and the connector type must be selected to align with the overall system design, and should include the maximum short circuit current of the system, maximum operating temperatures and cable run lengths. ••For field connections, use at a minimum #12 AWG/4 mm2 wires; insulated for a minimum of 85 C. Use copper wire only.

Where: Ns equals the maximum modules in series. Vmaxs equals the maximum system voltage. Please refer to module data sheet for actual Vmax rating, as some models are rated for 1000 V UL and 1000 V IEC. Vocm equals the module open circuit voltage at coldest conditions for the site (refer to local codes). WARNING: Installers shall adhere to all applicable local, regional, and national codes and regulations when designing and constructing the photovoltaic system Note: In colder climates, it may be necessary to further reduce the maximum number of modules in a series by using Vocm at the minimum expected operating temperature.

4.3 Grounding

Figure 2: Image of the grounding holes

Module frames and structures grounding must be compliant with all national and local regulations. SunEdison recommends grounding all module frames and associated structures in order to maintain a zerovoltage potential between the electrically conductive equipment and the earth in all scenarios. SunEdison modules use a coated aluminum frame for corrosion resistance. In order to ensure proper grounding the coating must be penetrated by the grounding method. A copper grounding wire with a minimum gauge of 12 AWG is recommended to carry the electrical ground load. Consult applicable codes to ensure the appropriate conductor diameter is used for the system. The grounding method must not allow direct contact of dissimilar metals with the frame of the module, as this would result in galvanic corrosion. UL 1703 recommends metal combinations not to exceed a voltage potential of 0.5. The frame has predrilled holes marked with a grounding sign as illustrated in Figure 2. These holes should be used exclusively for grounding. Do not drill additional holes or modify existing holes in the frame.

F-SERIES and R-SERIES  72-Cell Installation Guide 4.3  Option A: Metal Lug SunEdison recommends copper or tin plated grounding lugs rated for outdoor use and used with a #12 or larger wire. The use of a copper split bolt connector is authorized for well. Attach the grounding lug to the frame by referring to Figure 3 and the following steps: Figure 3: Option A Grounding Lug Assembly

Use stainless steel metric or English sets only. Please refer to the following list for the minimum hardware requirements for each set. Metric set - Stainless Steel Bolt M4 - Stainless Steel Nut M4 - Stainless Steel Flat Washer M4 - Stainless Steel Spring Washer M4 - Stainless Steel Lock-Toothed Washer M4 - Stainless Steel Slotted Washer M4 English set - Stainless Steel Bolt #8-32 - Stainless Steel Nut #8-32 - Stainless Steel Flat Washer #8-32 - Stainless Steel Spring Washer #8-32 - Stainless Steel Lock-Toothed Washer #8-32 - Stainless Steel Slotted Washer #8-32 Step 1: Place the grounding lug over the grounding hole on the exterior of the module frame. Step 2: Place a star washer directly between the bottom of the grounding lug and the exterior surface of the frame. Step 3: Place a bolt through the lug, star washer and frame grounding hole. Step 4: Secure the lug to the frame using a flat washer, split washer and nut. Step 5: Torque the bolt stack to approximately 1.5 –2.3 N·m (1.1–1.7 ft·lbs) to ensure the star washer penetrates the anodized frame.

4.3  Option B: Racking Manufacturer Integrated Grounding Methods

4.3  Option C: Bolt Wire Assembly

Integrated grounding methods must be appropriately certified to UL standards and must be in accordance with the specified instructions of the respective manufacturer. SunEdison modules can be grounded by bonding modules to a grounded racking system. SunEdison recommends using its internally developed integrated grounding clip, PN: 720256 with its piloted bolt, PN: 720230. The grounding clip utilizes a 304 stainless steel KEP nut to make the ground connection, and the geomet finished bolt carries the current to the grounded structure. The torque specification for the bolt and clip is 14.9 N·m (11 ft·lbs).

Step 1: Attach grounding lug at one of the designated aforementioned grounding hole locations. Using only stainless steel hardware, insert a stainless steel bolt first through the stainless steel cup washer, and then through the grounding hole. Step 2: Loosely add a stainless steel backing nut and a toothed lock washer to the bolt. Step 3: Bend the EGC into an Omega (Ω) shape to tightly fit between the partially installed bolt head and cup washer. The EGC will be exclusively in contact with the steel. Step 4: Tighten the bolt to approximately 4 N·m (35 in·lbs) of torque. The toothed washer must penetrate the coated aluminum.

Figure 4: Option B Grounding Lug Assembly

Step 5: Route the correctly sized ECG wire without bringing the wire into contact with the module frame.

Figure 5: Option C Bolt Wire Assembly

4.3  Option D: Alternative Grounding If the clip is not available, SunEdison also recommends using the BURNDY WEEBs integrated rack grounding, part numbers WEEB-ADC, WEEB-ADR, WEEB-WMR1 and WEEB-WMR2. These devices are made of 304 stainless steel that properly ground the modules with specialized teeth that penetrate both module and structure. Should you choose a rack integrated method that is not approved by UL please contact SunEdison before proceeding to determine compatibility.

To use other code compliant frame grounding methods that are UL certified contact SunEdison for approval.

F-SERIES and R-SERIES  72-Cell Installation Guide 5.0 Maintenance

5.1  String Grounding

Check the modules for any damages to the glass surfaces and frames on a regular basis. Routinely inspect all modules for safe electrical connections, sound mechanical connections, and for any shading or corrosion issues. If dirt or debris becomes built-up clean the glass using only a soft cloth, with a mild, non-abrasive detergent and water. SunEdison recommends using mild cleaning liquids; a neutral pH in the range of 6.0 to 8.0 is recommended. Chemicals with pH less than 6.0 or greater than 8.0 should be avoided as it may damage the glass surface and/or the anti-reflective coating. Please consult with the system designer to determine the best cleaning and inspection schedule based on local environmental conditions. Do not power wash, use harsh cleaning materials or coarse objects such as scouring powder, steel wool, scrapers, blades or other sharp instruments to clean the module. Use of any such methods and materials will void the product warranty. Do not wash modules with water that is more than 20 C cooler than the surface of the module. Doing so can cause the glass to crack. WARNING: Use caution when cleaning the back surface of the module to avoid scratching the substrate materials.

Silvantis F-series modules come in two types, PID-free and PID-resistant. PID-free panels have a “PID-free” designation on the nameplate label (Figure 6a) as well as a “P” on the right side of the bar code label (Figure 6b). String grounding requirements for the two types of modules are: ••PID-free modules do not require string grounding and are fully compatible with floating ground transformerless and micro-inverters, as well as with galvanically isolated inverters. ••PID-resistant modules: For string voltages greater than 100 V PID-resistant modules must be used with galvanically isolated inverters with the negative end of the string held at ground potential. Floating ground transformerless string inverters may not be used with PID-resistant modules. PID-resistant modules are fully compatible with microinverters where string voltage is less than 100 V, in which case string grounding is not required. Figure 6: PID-free module designations
