FIRST SOLAR First Solar Series 6™ Modules | USER GUIDE 12 of 29
© FIRST SOLAR, INC. | PD-5-200-06 REV 5.0
Series 6 Modules have been evaluated to operate in an ambient air temperature range of -40°C to +40°C
and have been tested to wind/snow loads as detailed in Tables 4.1 and 4.2. Test loads include a safety
factor of 1.5 above the design loads.
Series 6 Modules meet the following load ratings when mounted as specified in this User Guide and
evaluated according to the listed standard in Tables 4.1 and 4.2.

Symmetrically secure the module using a minimum of four frame contact points regardless if mounted with
top clamps or with SpeedSlot clamps. Other mounting solutions not discussed in this User Guide (Such as -
asymmetric mounting, higher load ratings, alternative clamp geometry, etc.) may be permitted, but require
