1.0 INTRODUCTION

The purpose of this guide is to provide general information regarding the proper installation and handling of SunEdison
photovoltaic modules that serve residential, commercial, and industrial segments. System design, construction, and
commissioning should be performed by qualified personnel only.

To ensure system integrity, designers, installers and operators must meet all mechanical and electrical requirements for
the system and its components. It is the responsibility of the system designer and installer to ensure that all codes and
requirements are followed as well.

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 PHOTOVOLTAIC MODULES PRODUCT CODE

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.

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 pallets 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

people.

• Precaution should be taken to avoid damage to the glass surface with or without anti-reflective coating due to improper
handling during storage or unpacking. Do not place or store modules with the glass facing down.

• Keep all electrical contacts clean and dry.

• 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.

• Do not allow unauthorized persons near the installation site or storage area of modules.

• Do not place any load on the module or twist the module frame.

• Do not stand, step, walk, or jump on the module.

• Do not drop or place objects on the modules such as tools.

• Do not handle modules with bare hands and avoid scratches, handling marks, or any damage especially to the front

glass of the module, backsheet, or electrical components.

• Do not mark the modules with sharp in struments.

• Do not leave a module unsupported or unsecured.

• Do not modify module frames in any way.

3.2 SAFETY

The following safety guidelines and best practices should be followed:

• All installations must be performed in compliance with all applicable regional and local electrical codes or other national
or international electrical standards.

• Use insulated tools during installation, troubleshooting and maintenance of photovoltaic 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.

• 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 problems.

• Follow industry best practices when commissioning, trouble shooting, disconnecting, or connecting a PV system.

• Trouble shooting should include planning, checking, disconnecting, cause seeking, replacement, and record keeping.

• 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 junction box or sub-components.

• Do not artificially concentrate sunlight on a module.

• Do not install or handle any broken modules. If a module is broken, or the back sheet is torn, contact with the surface or

frame can cause an electrical shock.

• Do not wear rings, jewelry, watches, or other metallic items while working with photovoltaic modules.

3.3 MAINTENANCE

Check modules, glass, and frames for damage. Regularly inspect all SunEdison 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 scratching the substrate materials.
