4.4 MECHANICAL INSTALLATION WARNINGS
• Installation and maintenance should be performed by qualified personnel only.
• Use insulated tools during installation, troubleshooting and maintenance of photovoltaic modules.
• Installers should adhere to all applicable local, regional, and national codes and regulations when designing and
constructing the photovoltaic system.
• Do not stand or walk on any surface of the modules. Do not place any objects or load on the surface of the modules.
• Precaution should be taken to avoid damage to the glass surface with or without anti-reflective coating due to improper
handling during installation.
• Mechanical structures should not contact the module backsheet under any expected load conditions.
• Additional mounting holes may not be drilled in the frame, glass or backsheet.
• Ensure that frame weep holes (see Appendix 8.1) are not obstructed by the mechanical installation.
• Mechanical installation of the module shall not cause the frame to torque more than 1 1/2".
4.5 ADDITIONAL MOUNTING METHODS
Use of the PanelClaw system (Part Number 500000501 and 500000701) is permitted with SunEdison solar PV modules.
Structures manufactured by PanelClaw Inc. use a special clamp, or "claw" designed to attached to the flange
of the PV module at all four corners, on the two short frame ends. PanelClaw is ULcertified for electric
bonding and grounding. See the PanelClaw installation guide for proper grounding management. For proper placement,
attach a claw over the module frame flange at each of the four designated locations and tighten the screw so that the
claws are flush with the long and short ends of the module flange. This mounting method has been tested to a maximum
rating of 50 psf in the negative and positive direction. See case two and three from above as well as the PanelClaw installation
guide for information on the installation of the clamps. The PanelClaw should only be used on modules with flanges of 30 mm.
Use of the SunEdison AP90 Single Axis Tracker is authorized for use as well. Please refer to the AP90 installation guide for
specific instructions. Installation guides can be found on the SunEdison website www.sunedison.com
