3.0 MODULE OVERVIEW
MEMC 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 modied or removed.
* Tempered glass may have AR 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 identication.
• Damage to the glass surface or the anti-reective coating can impact the power output and overall eciency 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.
3.1 STORAGE, UNPACKING, AND HANDLING
• Packaged modules must be stored in a dry and ventilated area.
• Packaged modules must not be exposed to rain, snow, hail or other environmental conditions that may compromise the
packaging material and the modules.
• Packaged modules must be on appropriate provided pallets and must not be stacked more than two pallet high for storage.
• Once the modules are opened, store modules in a dry and ventilated room.
• Modules should never be stored in a wet environment.
• Upon unpacking, do not carry a module by its wires or junction box. Only carry a module by its frame with two or more

3.3 MAINTENANCE
Check modules, glass, and frames for damage. Regularly inspect all MEMC Silvantis Solar Modules for safe electrical connections,
sound mechanical connections, and freedom from shading and corrosion. If dirt or debris buildup becomes excessive, periodically
clean the glass only with a soft cloth using mild, non-abrasive detergent and water. When 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 AR coating. Please consult with system designer to decide the cleaning and inspection frequency
according to local environmental conditions.
Do not power wash or use harsh cleaning materials or objects such as scouring powder, steel wool, scrapers, blades, or other sharp
instruments to clean the glass surface of the module. Use of such materials will invalidate the product warranty.
WARNING: Use caution when cleaning the back surface of the module to avoid penetrating the substrate materials.

4.0 MECHANICAL INSTALLATION
4.1 PLANNING AND DESIGN
• Before installation, check to ensure all 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 re-resistant roof covering rated for the application.
• Mechanical structures should not contact the module backsheet under any expected load conditions
• Consider the following factors during system design, which will inuence performance:
a) MEMC 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 airow across the back of the
module.
d) Allow a minimum spacing of 10 mm between modules for thermal expansion.
4.2 MODULE INSTALLATION OPTIONS FOR MOUNTING LOCATIONS
For mounting locations for clamps or bolt for specied load, please refer to Table on page 6.
5 of 14
• 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.
• 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 below (referring
to chart showing clamp and bolt mounting locations).
• If using bolts, eight mounting holes are provided on the rear side the module frame as shown in Appendix 8.1. Use a stainless
steel bolt stack no smaller than ¼"-20 or M6, with two at washers and a locking washer as shown in Appendix 8.2.
• To ensure an adequate clamping area, all clamps used should comply with the following general conditions:
1. Clamp height must correspond to 50 mm frame height
2. Clamp must have a minimum width of 38 mm
3. Clamp depth must be between 6 mm to 10 mm
• All fasteners used to x the modules with clamps should be stainless steel, and no smaller than ¼”-20 or M6.
• To provide adequate xing or clamping force, torque the minimum recommended fasteners to 13.6 - 16.3 N.m [10 - 12 ft lb].
• 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 modied or tampered with in any way.
8 of 14
NOTE: Installers should ensure that the polarized locking connectors are from the same supplier when connected on the
same string. We do not recommend mixing polarized interlocking connectors from dierent manufacturers—including
connections at the inverter, combiner boxes, and modules.
• 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 signicantly dierent than STC. MEMC suggests multiplying specied ratings by a minimum
of 1.25* or more when specifying the system and balance of system components. 1.25* 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: N
= Vmaxs / Voc
s
m
Where:
equals the maximum modules in series
N
s
equals the maximum system voltage
Vmax
s
is limited to a maximum of 1000 V for IEC and 600 V for UL
Vmax
s
equals the module open circuit voltage at coldest conditions for the site (refer to local codes)
Voc
m
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 Voc
m
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 sucient length to connect to adjacent modules in either a portrait or landscape conguration. 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 needed for all series string wiring. The maximum operating temperature of wires and connectors should
not exceed 85ºC.
© Copyright 2012 MEMC Electronic Material
Installation Manual: MEMC Silvantis 60 cell PV Modules
WARNING: It is not recommended to mix connectors from dierent suppliers within the same string. This includes
connections at the inverter, combiner boxes, and 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. MEMC 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 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 eld connections, use at a minimum #12 AWG/4 mm
5.3 GROUNDING
• The module frame includes several labeled grounding holes. These holes may not be used for any other purpose.
• MEMC recommends a Burndy BGBL-4 AL lay-in lug for grounding.
• Only Negative grounding circuits (negative polarity to ground) shall be used within the array design.
• Attach the grounding lug to the frame as follows:
wires insulated for a minimum of 85°C. Use copper wire only.
9 of 14
Step 1: Use stainless steel hardware.
Step 2: Place the grounding lug over the grounding hole on the exterior of the module frame.
Step 3: Place a star washer directly between the bottom of the grounding lug and the exterior surface of the frame.
Step 4: Place an M4 or #8-32 bolt through the lug, star washer and frame grounding hole.
Step 5: Secure the lug to the frame using a at washer, split washer and M4 or #8-32 nut.
Step 6: Torque the bolt stack to approximately 1.5 N.m (or 1.1 foot pounds) to ensure the star washer scratches the
anodized frame.
