Please note the following guidelines that apply to the installation site:

• Solar modules are not explosion-proof and are not suitable for use in explosive environments.
  • Do not operate solar modules near highly flammable gas and vapors (e.g. gas tanks, gas stations).
  • Do not install modules in enclosed space.
  • Do not install modules in locations where they may be submerged in water (e.g. floodplains).
  • Do not use modules as a substitute for the normal roofing (e.g. modules are not watertight).
  • Do not install modules in close proximity to air conditioning systems.
  • Do not install modules above 13,120ft (4,000m) altitude above sea level.
  • Contact with saline water (e.g. spray water from the sea) and salt aggregation on the modules must be avoided.
  • Do not bring any chemical substance (e.g. oil, solvent etc.) into contact with any part of the panel. Only substances, which are released by Q CELLS, are allowed to be used during installation, operation and maintenance.
  • Any installation of modules on surfaces of water is prohibited. This includes installations on floating as well as pile-based platforms. Q CELLS may extend the coverage of its warranty to such installations, based on a case by case assessment of the system design and location. A prior written consent by the warrantor is required in any case.

Prevention of Shadowing Effects
Optimal solar irradiation leads to maximum energy output:

• For this reason, install the modules so that they face the sun.
• Avoid shadowing (due to objects such as buildings, chimneys or trees).
• Avoid partial shading (for example through overhead lines, dirt, snow).

Limitations
The solar modules are designed for the following applications:

• Operating temperatures from –40°F to +185°F.
• Pull loads and push loads according to chapter 2.3 (‘Test Load’ in accordance with IEC 61215 and ‘Design Load ×1.5’ in accordance with UL 61730).
• Installation using a mounting structure for solar modules.

Mounting Structure Requirements
Requirements for the mounting structure:

• Conform to the necessary structural requirements.
• Compliant with local snow and wind loads.
• Properly fastened to the ground, the roof, or the façade.
• Forces acting on the module are relayed to the mounting substructure.
• Ensures sufficient rear ventilation of the module.
• Avoid the usage of different metals to prevent contact corrosion.
• Allows for stress-free expansion and contraction due to temperature fluctuations.
  • Ensure that no additional forces are applied through the mounting system into the module except for the wind and snow loads. Additional forces and moments of torque at the mounting positions caused by torsions, displacements or vibrations in the mounting system are not allowed.
  • Ensure that the clamps and the mounting frame are compatible.

Clamp System Recommendations

MOIUNTING OPTIONS| REQUIREMENTS
---|---
All|   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 have been determined with the following clamp parameters: clamp width =

1.57 in (40 mm) and clamp depth = 0.39 in (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, CL2a, CL3, FB1, FB2|   Ensure that module frame is fixed directly on the rail of the substructure (no spacer allowed between the module and substructure).
CL1a|   With push test loads of 5400 Pa: 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 55.12 in (1400 mm).
CL1b|   Using of short mounting rails are permissible, if they overlap under the module less than 8.27 in (210 mm). Minimum clearance between frame bottom edge and roof top must be ≥ 1.38 in (35 mm).
CL1b, CL2b, CL3, FB2, CL6c, CL6d|   A minimum support depth of 0.59 in (15 mm) is required on the back side of the module.
CL5|   The minimum required support depth on the module backside is 0.39 in (10 mm) on long frame side and 0.59 in (15 mm) on short frame side.
IP1|   Ensure minimum support depth of 0.59 in (15 mm) on the backside and 0.39 in (10 mm) on the front side of the module.
FB1, FB2|   Use M8 corrosion-proof screws and washers (diameter ≥ 0.62 in (15.8 mm)) for mounting slots (Detail A, Fig.1). Mounting screws and washers should have the same material properties.
CL6c, CL6d|   Use of short mounting rails under the modules are permissible, if they do not touch the laminate under load.

ELECTRICAL LAYOUT

Module Selection
For detailed key electrical data, please refer to the product data sheet for the respective product. (available at www.q-cells.us)

• 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. Accordingly, the values of ISC and VOC marked on the module should be multiplied by a facot of 1.25 when determining:

• the component voltage ratings,
• conductor ampacities,
• fuse sizes,
• size of controls connected to the PV output.

Refer to Section 690-8 of the National Electrical Code for an additional multiplying factor of 125 percent (80 percent derating) which might be applicable.

• Please follow the valid national guidelines for the installation of electrical systems (refer to section 690-8 of the NEC for an additional multiplying factor of 125 percent [80 percent derating] which may be applicable).

Series Connection
Connection of modules in series is only permitted up to the maximum system voltage as listed in the applicable datasheet.

• Take into account all possible operating situations and all relevant technical norms and regulations when designing the system. This will ensure 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:
Layout with a limited number of parallel connected strings:
Without undertaking further current blocking measures, a maximum of two module strings may be operated in parallel on a single inverter or MPP tracker.
Layout with string fuses:
Use overcurrent devices (e.g. fuses) according to the relevant standards in each string. Use PV-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

DANGER!
Risk of fatal injury due to electric shock!
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.

• 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 120V, the safety extralow 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

AFTER INSTALLATION

GROUNDING

Protective Grounding
In order to prevent electrical shock or fire, the frame of the module as well as any non-current-carrying metal parts of the system must be grounded. While this section provides some information about grounding the Q CELLS frames and modules, reference should be made to local statutes and regulations for specific requirements on grounding. The U.S. National Electrical Code addresses these issues in Article 250. A module with exposed conductive parts is considered to be in compliance with this standard only when it is either electrically grounded in accordance with the manufacturer’s instructions and the requirements of the National Electrical Code, ANSI/NFPA 70 (2014-2017), or when the bonding means has been evaluated with this module to UL 2703. Proper grounding is achieved by bonding all exposed non-current carrying metal equipment to the appropriately sized equipment grounding conductor (EGC) or racking system that can be used for integrated grounding. Q CELLS frames are protected from corrosion with an anodized coating, which has to be penetrated in order to ensure proper bonding. The different methods listed below are suggested methods for an appropriate bond between the frame and the EGC or racking system (that will have to be properly grounded). The method appropriate for any individual installation will depend on multiple factors.

Option A: Use of a grounding lug
A listed grounding lug can be bonded to the frame using the grounding
holes pre-drilled in the frame. These holes are marked with a ground symbol, as shown below on the frame section drawing: To install the grounding lug, follow the specified instructions of the manufacturer. The grounding lug should be made of stainless steel or tin plated metals such as aluminum to avoid corrosion. The grounding lug should be attached to the frame grounding hole using a stainless steel screw, toothed lock washer or KEPS nut (in order to penetrate the anodized layer) and backing nut. Care should be taken to avoid the use of grounding hardware of dissimilar metals, which may lead to corrosion.
Option B: Integrated grounding methods
The Q CELLS modules can be bonded with the racking system using UL1703 or UL2703 certified integrated grounding methods.The racking system will then have to be grounded so that the overall system is properly grounded. The listed racking system and grounding device should be installed in accordance with the manufacturer’s instructions. An example of such an integrated grounding method is the use of a WEEB clip or Schletter plate between the module and the racking system, when mounting the module. The WEEB washers are generally compatible with Q CELLS modules, however each combination module/racking system requires a specific WEEB washer size. Note that WEEB clips are intended for single use only; they must not be reused after removal or loosening. Refer to Wiley’s installation instructions for the specific use of WEEB washers. An example of such integrated grounding method is the use of a washer recognized as meeting UL2703 requirements between the module and the racking system, when mounting the module. For example, WEEB washers are generally compatible with Q CELLS modules, however each combination module/racking system requires a specific WEEB washer size. Note that WEEB washers are intended for single use only; they must not be reused after removal or loosening. Refer to Wiley’s installation instructions for the specific use of WEEB washers.

FAULTS AND DEFECTS

DANGER!
Risk of fatal injury due to electric shock!

• Do not attempt to fix any problems yourself (e.g. glass cracks, damaged cables).
• Please contact an installer or Q CELLS Technical Customer Service Department.

DISPOSAL

• Do not disconnect modules yourself.
• Please commission a trade specialist.
• Dispose of modules in accordance with the local disposal regulations.

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
WARNING!
Risk of injury due to hot and live modules!

• Only clean modules that have cooled down.
• Do not carry or wear any electrically conductive parts.

WARNING!
Risk of falling due to unsecured access!

• 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.

• 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.

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.).
