Thank you for choosing SunEdison's Silvantis modules. This guide provides information regarding the proper installation and handling of Silvantis modules.
Silvantis modules consist of a series of electrically interconnected monocrystalline solar cells that are sealed within a laminated sheet of tempered, low glare anti­reflective coating (ARC) glass superstrate, and EVA back sheet substrate. These laminates are secured inside an aluminum frame to provide rigidness and a mounting mechanism to affix to sub-structures. Do not modify or remove frames.
Please review all the sections that pertain to proper installation of modules listed in this guide. The instructions detailed in this guide must be followed throughout the module’s lifetime deployment. If you need additional information about the safe, proper use and handling of SunEdison photovoltaic module products, please contact SunEdison.

2.0 Safety
Ensure to follow all safety guidelines stated below. Failure to do so can cause injury, damages, or a void in the module warranty.
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.
• Do not twist the module frame.
• 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.
• 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:
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.
• 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.
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.
