3.0 MODULE OVERVIEW
SunEdison Silvantis Photovoltaic modules consist of a series of electrically interconnected crystalline silicon solar cells that are
sealed within a laminated sheet of tempered glass superstrate* and EVA/back-sheet substrate. These laminates are secured
inside an aluminum frame to provide rigidity and a means for attachment to mounting sub-structures. The frames should not be
modified or removed. * Tempered glass may have anti-reflective coating.
• Photovoltaic modules are designed and constructed 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 these labels. This
may be required for product identification.
• Damage to the glass surface or the anti-reflective coating can impact the power output and overall efficiency of the
system. Scratches, handling marks, or any damage to the glass surface must be avoided.
• For best performance and to avoid potential issues, keep the front side of the module clean and free of obstructions
including covers, tape, adhesives, paint and debris.

4.0 MECHANICAL INSTALLATION
4.1 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.
• For roof installations, utilize a fire-resistant roof covering rated for the application. A minimum clearance of 6 inches is
required between the roof and bottom of the module frame.
• Mechanical structures should not contact the module backsheet, any racking, or 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 such as: walls, buildings, trees, groundcover, snow cover, or dust and debris that have
the potential to shade or damage the modules.
c) Elevated temperatures will decrease energy yield, so designs should ensure adequate airflow across the back of
the module.
d) Allow a minimum spacing of 10 mm between modules for thermal expansion.
4.2 MODULE MOUNTING OPTIONS
For clamp or bolt mounting locations, please refer to table 4.2A
• 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. No more than two clamps per side may be used.
• 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 table 4.2A.
• 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 Table 4.2A. 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.

5.0 ELECTRICAL INSTALLATION
5.1 PLANNING AND DESIGN
• All modules are manufactured with a sealed junction box and 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 when connected on the
same string. 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 section 7.2 for connector types.
• 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 Vmpp. Modules may operate
under conditions which may be significantly different than STC. SunEdison suggests multiplying specified ratings by a
minimum of 1.25 times or more when specifying the system and balance of system components. Installer should adhere
to all local, regional and national codes before planning and design of the system. Refer to local codes before planning
and design of the system. For detailed electrical characteristics, please refer to Section 7.0, page 10 through 11 of this
Installation Manual.
• Determine the maximum number of modules connected in series using the following formula: Ns = Vmaxs/ Vocm
Where:
Nsequals the maximum modules in series
Vmaxsequals the maximum system voltage and is limited to a maximum of 1000 V for IEC and 600 V for UL
Vocmequals the module open circuit voltage at coldest conditions for the site (refer to local codes)
WARNING: Installers should 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 series by using Vocm
at the minimum expected operating temperature.
5.2 MODULE WIRING
• The module includes wires and polarized locking connectors from the junction box on the back of the module. The
wires have sufficient length to connect to adjacent modules in either a portrait or landscape configuration assuming
the minimum spacing between module frames. Field replacement of connectors or cables must be avoided and it will
invalidate the product warranty. Polarized locking connectors of the same type and make are required for all series string
wiring. The maximum operating temperature of wires and connectors should not exceed 85ºC.
• When installing panels in landscape orientation, use of the 1.3 meter lead lengths will ensure enough cable length
to make adjacent, module-to-module, string connections, assuming a maximum spacing of 50mm between adjacent
modules.
• When installation panels in portrait orientation, use of the .55 or 1.0 meter lead lengths will ensure enough cable length
to make adjacent, module-to-module, string connections, assuming a maximum spacing of 50mm between adjacent
modules.

• Always wire modules so that proper polarity is maintained. Avoid placing excessive tension on the cables.
• There is no limit to the maximum number of series strings that can be combined in parallel. However, when doing so,
each string must include overcurrent protection with a maximum rating of 15A. SunEdison recommends the use of DC
rated fuses or overcurrent protection devices with the appropriate maximum voltage rating.
• Do not connect modules of three or more strings directly to a parallel bus.
• The cross-sectional area 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 mm2wires insulated for a minimum of 85°C. Use copper wire only.
5.3 GROUNDING
WARNING: Only negative grounding circuits (negative polarity to ground) shall be used within the array design.
Transformerless inverters with floating grounding are not acceptable.
• All module frames and mounting racks must be properly grounded in accordance with all local and national electrical
codes, using methods and devices that are UL 1703/2703 certified.
• Lug Method: A copper, stainless steel, or tin plated grounding lug that is rated for outdoor use and uses no smaller than
a #12 wire is acceptable. The use of a copper split bolt connector is authorized for use as well.
• Alternative Methods: Other code compliant frame grounding methods that are certified to UL 1703/2703 are
acceptable.
• The frame has predrilled holes marked with a grounding sign as illustrated below. These holes should be used
exclusively for grounding purposes and may not be used for any other purpose. Do not drill additional or modify
existing holes in the frame.
