    1 of 26 INTRODUCTION This document provides information on First Solar Series 6 Plus modules (including both Series 6 Plus SL and Series 6 Plus HL) for system designers, installers, and maintenance personnel. In instances that do not apply to both the Series 6 Plus SL and Series 6 Plus HL, the User Guide will specifically name and detail both product types as necessary.

  • Page 5: Safety

    All instructions and safety information should be read and understood before attempting to handle, install, or electrically connect First Solar modules. Failure to follow safety, installation, and handling instructions may result in injury. Only qualified personnel should install, operate, or maintain PV modules or systems.
  • Page 6 DANGER Reverse currents higher than the rated values for a First Solar module, may result in module failure, including module breakage due to RCOL. Extreme and continuous RCOL conditions may cause a fire or create electrical shock hazards. To avoid RCOL: Maintain equivalent voltage in parallel strings by installing an equal number of modules ►...

    Plus First Solar Series 6 Plus Modules | USER GUIDE FIRST SOLAR 11 of 26 7.2 MOUNTING LOCATIONS & LOAD RATINGS The interface of the mounting structure to the module frame must meet the technical requirements specified in this User Guide. The mounting system design must provide adequate support for the module to prevent load damage from occurring based on the loading requirements for the given application and the chosen mounting locations.
  • Page 15 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 evaluation by First Solar (technicalsupport@firstsolar.com). First Solar reserves the right to reasonable access to validate proper installation.
  • Page 16 Plus First Solar Series 6 Plus Modules | USER GUIDE FIRST SOLAR 13 of 26 • Design the Series 6 Plus module mounting interfaces to utilize the SpeedSlot feature, given the universally consistent interface dimensions for both Series 6 Plus SL and HL module types. This avoids the potential risk in managing the different rail top clamp height dimensions between Series 6 Plus SL and HL products.

  • Page 17: Top Mounting

    Figure 5. Module clamps may not continuously span the top of the frame across the midpoint of the long edge frame (to allow for module deflection). Clamps that do not meet the minimum requirements may not preserve module certifications or warranty and must be evaluated by First Solar (technicalsupport@firstsolar.com).
