  • Page 17: Top Mounting

    It is recommended all array positions be designed to mechanically accommodate the FS-6XXX-P / FS-6XXXA-P model types, given their ability to be utilized in all array zones. For the same reason, First Solar will typically provide these FS-6XXX-P / FS-6XXXA-P model types as spares and/or warranty replacements.

    First Solar Series 6™ Modules | USER GUIDE FIRST SOLAR 15 of 29 7.5 SPEEDSLOT MOUNTING The Series 6 Module frames include six SpeedSlots on each side, as shown in Figure 7. SpeedSlot clamps must either extend 10 mm (0.39 in) beyond the inner edge of the frame, or have a retention feature to prevent module frame dislodgement under load.

  • Page 19: Module Orientation

    First Solar Series 6™ Modules | USER GUIDE FIRST SOLAR 16 of 29 7.6 MODULE ORIENTATION PV performance modeling software, such as PlantPredict (http://www.plantpredict.com), should be used to determine the optimum orientation and tilt angle for each location. Mount modules in portrait orientation for applications where row-to-row shading could occur. Landscape orientation is permitted only in flat mount applications where the module long edge is not completely shaded and when compliant with Section 7.7 Module Shading Considerations.

  • Page 22: Electrical Interconnection

    Module-to-module and module-to-harness interconnection must utilize the same manufacturer and type of connectors. First Solar cannot guarantee that connectors from different manufacturers or type of connectors will be mateable. Any damage to the module resulting from any such interconnection will not be covered by the First Solar module warranty.

  • Page 23: Inverter Compatibility

    First Solar Series 6™ Modules | USER GUIDE FIRST SOLAR 20 of 29 Wiring harnesses are recommended in system designs. The shorter string size and low string current of Series 6 Modules make it possible to connect multiple strings together in parallel and return a single pair of DC cables to the combiner box or string inverter.

  • Page 24: Grounding Method

    21 of 29 7.11 GROUNDING METHOD First Solar recommends Series 6 Modules be used in negative-grounded systems. Modules must not be subjected to negative voltage bias conditions that can occur in voltage floating or bi-polar systems (subjecting modules to conditions that could drive potential induced degradation).

  • Page 26: Maintenance

    Other snow clearing methods, such as blowers, may be used depending on snow conditions and if approval by First Solar. To prevent pile up and overload, periodically clearing snow from the bottom modules first in an array is a critical process.

  • Page 27: Module Cleaning Guidance

    First Solar Series 6™ Modules | USER GUIDE FIRST SOLAR 24 of 29 8.2 MODULE CLEANING GUIDANCE Series 6 Modules do not require cleaning in most climates. Installed modules may collect a light layer of dust and/or dirt (soiling) over time and periodic rainfall should be sufficient to remove light soiling in most cases.

  • Page 28: Module Disposal

    First Solar recommends no more than 90 lb (40.8 kg) per module that is evenly distributed while cleaning. Specific contact points (wheels or belts) can affect the load and pressure placed on the modules.
