solar modules. The mechanical stability of the mounting system including clamps has to be evaluated by the system supplier. The listed test load values have been determined with the following clamp parameters: clamp width = 40 mm and clamp depth = 10 mm.

The system installer is responsible for the determination of location-specific load requirements. Ensure, that the connection cables of the junction box do not run between laminate and mounting rails

Modules bend under load. Therefore, sharp objects (e.g. screws, ballast stones, rail ends, rails with burrs or sharp corners) must not be placed near the module backside so as not to touch the laminate under load.

Ensure that the junction boxes do not touch the mounting structure (e.g. shorts rails, ballast, etc.) or the rooftop under load. Clamps or insertion profiles etc. must not touch the glass (even under load).

Unbalanced loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased loads must be removed or avoided by technical measures.

CL1a| Clamping range 20 – 450 mm: The clamp position is variable in the given range but the distance between the clamps along the long side of the module (span) must not be larger than 1300 mm.
CL1a, CL2a, CL3, FB1, FB2, CL6a| Ensure that module frame is fixed directly on the rail of the substructure (no spacer allowed between the module and substructure).
CL1b| Using of short mounting rails are permissible, if they overlap with the module less than 210 mm. Maintain a minimum distance (clearance) of ≥ 35 mm between frame bottom edge and roof top or ballast
CL1b, CL2b, CL3, FB2| Minimum support depth of 15 mm is required on the back side of the module.
CL5| Minimum required support depth on the module backside is 10 mm on long frame side and 15 mm on short frame side.
IP1, IP2| Ensure minimum support depth of 15 mm on the backside and 10 mm on the front side of the module.
FB1, FB2| Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm) for mounting slots (Detail A, Fig.1). Mounting screws and washers should have the same material properties.
CL6c| Using of short mounting rails are permissible, if they overlap with the module less than 150 mm. Maintain a minimum distance (clearance) of ≥ 50 mm between frame bottom edge and roof top or ballast

Module Selection
For detailed key electrical data, please refer to the actual data sheet referring to the relevant Module (available at www.qcells. com/au/).

• For maximum energy yields, mismatches of specified electric current (IMPP) of more than 5% should be avoided for all modules connected in series.

Safety Factor
During normal operation, a module may generate a greater current and or higher voltage than that determined under standardized test conditions. Please use a safety factor of 1.25 for the following:

• Calculating the vol tage measurement values (VOC) of components
• Calculating the current measurement values (ISC) of conductors
• Sizing of control systems connected to the outlets of the solar modules
• Please follow the valid national guidelines for the installation of electrical systems.
• Prefer to the latest revision of AS/NZS 5033 (including all relevant amendments) and the Clean Energy Council Guidelines (for Australia).

Series Connection
Connection of modules in series is only permitted up to the maximum system voltage as listed in the applicable data sheet of all the relevant modules to be installed.

• Take into account all possible operating situations and all relevant technical norms and regulations when designing the system. It has to be ensured that the maximum system voltage, including all necessary safety margins, is not exceeded.
• Take the voltage limit of the inverter into account when determining the maximum number of modules in the string.

Parallel Connection
Modules may be damaged by the occurrence of reverse currents (caused by module defects, ground leaks, or defective insulation).

• Ensure that the maximum reverse current load capacity indicated in the data sheet is met.

In order to limit reverse currents that may occur, we recommend using the following safety options:

1. Layout with a limited number of parallel connected strings : Please refer to the latest revision of AS / NZS 5033 (including all relevant amendments) for parallel string overcurrent protection requirements.
2. Layout with string fuses : Use overcurrent devices (e.g. fuses) according to the relevant standards in each string. Use gPV-fuses according to IEC 60269-6. Observe the maximum permitted number of strings as indicated in the specifications provided by the respective string fuse manufacturer and the technical guidelines.

NOTE! When installing different product versions, the lowest minimum permitted reverse current load capacity applies.
Inverters
Inverters with or without transformers may be used.

• Never access the installation area alone or without taking adequate security precautions.
• Please commission a trade specialist.

NOTE! Module surface damage may occur!

• Remove snow and ice carefully without force (e.g. with a very soft broom).
• Do not scratch off dirt.
• Module cleaning has to be done by qualified personnel according to the state of the art and taking into account all relevant safety issues and general product properties, e.g., but not restricted to:
  • electrical safety
  • mechanical stability (load limits depending on the actual mounting options)
  • chemical suitability (no effect to any of the module‘s components, e.g. cable, connector, silicone)
  • no abrasive materials.

NOTE! Dust and dirt are abrasive materials!

• The situation for each individual project (or type of dirt) must always be professionally evaluated.
• Wrong cleaning may cause damages such as, but not limited to, damages to the glass surface (e.g. scratches) and AR coating, power loss, delamination, loss of frame-to-laminate bond, reduced snow and wind load capability etc.

Apart from the above, each customer is free to choose the method of cleaning. However, possible damages, caused by the cleaning or related to the cleaning tools or agents shall not be covered by the module‘s Product and Performance Warranty. Therefore it is recommended to use only the tools and agents which have already been successfully tested and used with PV modules, to prevent possible damage. Isopropyl alcohol (IPA) can be used selectively to remove stubborn dirt and stains within one hour after emergence.

• Note! Module damage may occur!
  • Do not clean modules with water if there is a risk of frost.
• Free the substructure from any dirt and debris (leaves, bird nests, etc.).
