ATTENTION

Ä The loads in the table are related to the mechanical stability of the solar modules. The mechanical stability of the mounting system including clamps has to be evaluated by the system supplier. The listed test load values for Q CELLS were 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.

Ä Ensure, that the sub construction does not touch the junction box (even under load). The clamps or insertion profiles etc. must also not touch the glass (even under load).

Ä Ensure, that the junction box’s connection cables do not run between the laminate and the mounting rails.

Ä CL1b: Minimum clearance between frame bottom edge and substructure: ≥ 30 mm, short rails are permissible if they overlap with the module less than 210 mm.

Ä A minimum support depth of 15 mm is required on the backside of the module for IP1, IP2, CL2b, CL3, CL4 and CL5. For the front side of the module for IP1 and IP2, this minimum support depth should be 10 mm.

Ä For CL1, CL2a and CL3 with rails: Ensure that the module frame is fixed directly on the rail of the substructure (no spacer allowed between the module and substructure).

Ä The module bends under loads. Therefore, sharp objects (e.g. screws) must not be mounted near the module backside.

Ä Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm or ≥ 0.62 in) for FB1 and FB2 mounting.

ELECTRICAL LAYOUT

Module Selection

For detailed key electrical data, please refer to the actual data sheet referring to the relevant Module (available at www.q-cells.com).

• 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 standardised test conditions. Please use a safety factor of 1.25 for the following:

• Calculating the voltage 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.
• Please refer to the latest revision of AS / NZS 5033 (including all relevant amendments) and the Clean Energy Council Guidelines (for Australia).

Series Connection

The connection of modules in series is only permitted up to the maximum system voltage as listed in the applicable datasheet of all the relevant modules to be installed.

1. 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.
2. 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:
• parallel-connected strings : Please refer to the latest revision of AS / NZS 5033 (including all relevant amendments) for parallel string overcurrent protection requirements.
• 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.

SAFETY AND TRANSPORT

PREPARATION OF INSTALLATION

MODULE INSTALLATION

ELECTRICAL CONNECTION

When disconnecting an electric circuit carrying direct current, electric arcs can occur that may result in life-threatening injuries.

• Do NOT unplug the cable when under load.
• Do NOT connect any exposed cable ends.
• Electrical work may only be performed by qualified and skilled personnel (see page 3).

A solar module generates electrical current and voltage even at a low intensity of illumination. Sparks and electric arcs may result from the separation of a closed circuit. These can result in life-threatening injuries. The danger increases when several modules are connected in series.

• Ä Please be aware of that the entire open circuit voltage is active even at low levels of solar irradiation.
• Please follow the valid national regulations and safety guidelines for the installation of electrical devices and systems.
• Please make sure to take all necessary safety precautions. With module or phase voltages of more than 120 V, the safety extra-low voltage range is exceeded.
• Carry out work on the inverter and the wiring with extreme caution.
• Ensure that the modules are disconnected at the inverter prior to separation.
• Be sure to observe the time intervals specified by the inverter manufacturer after switching off the inverter.
• Make sure that the plugs can not be connected unintentionally.
• Before working on the contacts, check them for safety extra-low voltage.

MAINTENANCE AND CLEANING

Q CELLS solar modules are known for a long operating life and minimal maintenance effort and expense. Dirt and grime are usually washed away by rain. If the module is fully or partially shaded by dirt or debris (e.g., plants, bird droppings), it needs to be cleaned to prevent a loss of performance.

Maintenance

• The PV system has to be inspected regularly by certified personnel:
• The time intervals and extent of the inspection can depend on local circumstances (e.g. salt, ammonia content in the air, high humidity etc.). The customer/operator must inform himself about time intervals and extend of necessary inspections.
• Inspections have to be performed especially after extraordinary events (e.g. storm, hail, high snow loads etc.)
• During the inspections, it has to be checked that the components are secure, undamaged and clean

Cleaning

• Only clean modules that have cooled down.
• Do not carry or wear any electrically conductive parts.
• Never access the installation area alone or without taking adequate security precautions.
• Please commission a trade specialist.
• Remove snow and ice carefully without force (e.g. with a very soft broom).
• Do not scratch off dirt.
• Rinse dirt (dust, leaves, etc.) off with lukewarm water or use, only for the glass surface, an alcohol-based glass cleaner. Do not use abrasive detergents or surfactants for any part of the panel.
• Use a soft cellulose cloth (kitchen roll) or sponge to carefully wipe off stubborn dirt. Do not use microfleece wool or cotton cloths. Isopropyl alcohol (IPA) can be used selectively to remove stubborn dirt and stains within one hour after emergence.
• Please follow the safety guidelines provided by the IPA manufacturer.
• Do not let IPA run down between the module and the frame or into the module edges.
