2.2Requirements

Installation Site
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 Qcells, 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. Qcells 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).

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 Use customary clamps that satisfy the following requirements: Clamp width: 1.57in (40mm). Clamp height compliant with a 1.18in (30mm) frame height. Clamp depth: 0.28-0.47in (7-12mm). (applicable for all CL
clamping mounting options at section “2.3 Mounting options”) Clamps are not in contact with the front glass. Clamps do not deform the frame. Clamps that satisfy the structural requirements based on the
conditions of the installation site according to the applicable regulations and technical standards. Long-term stable clamps that securely affix the module to the mounting frame.
Module Orientation Requirements Vertical or horizontal installation is permitted.
Ensure that rain and melting snow can run off freely. No water accumulation. Ensure that the drainage holes in the frame are not covered. No sealing.
Maintain the permissible angle of inclination. Minimum angle of inclination: 3° Inclination angles above 75° may be limited by
local regulations Standing water on the modules glass needs to be avoided.

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 andDesign 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.

2.3Mounting options

REQUIREMENTS OF ALL MOUNTING OPTIONS
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 (40mm) and clamp depth = 0.39 in (10mm). 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.
Loads according to IEC 61215-2:2016 and UL 61730-2:2017 except for design loads lower than 1600 Pa which
do not fulfill the requirements of the standards. The test procedure is always according to IEC 61215-2:2016.
Design loads result from the safety factor 1.5.

2.4Electrical layout

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

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 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.

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 extralow voltage.

4.4After installation
Ensure that all necessary safety and functional tests have been carried out according to applicable standards.

Note! Module damage may occur!
Ensure that the plug connections are secured away from any water-channelling surface.

SOLAR
Danger! Risk of fatal injury due to electric shock! Ensure that all electrical components are in a proper, dry, and safe condition.

Do not connect modules with different orientations or angles of inclination in the same string.

Integrate the system into the existing lightening protection system in accordance with the applicable local regulations.

Warning! Fire Risk! Do not use light concentrators (e.g. mirrors or lenses).

Ensure for a tight connection between the plugs. Plugs click together audibly.

To avoid complex cabling arrangements, it is often advantageous to rotate some modules 180°. Module orientation can clearly be identified from the front side by the serial number and barcode labelled behind the module glass on the side with negative connection cable.

Ensure that the cabling is not exposed and/or hanging and is protected from dirt, moisture and mechanical friction.

5 Grounding

6 Faults and defects

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 Qcells 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 noncurrentcarrying metal equipment to the appropriately sized equipment grounding conductor (EGC) or racking system that can be used for integrated grounding.
Qcells 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.
Dimensions shown are in inches.
0.79″ ±0.08

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 Qcells 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 manufacturers’ instructions. An example of such 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 Qcells 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 Qcells 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.

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 Qcells Technical Customer Service Department.
7 Disposal
Do not disconnect modules by yourself. Please commission a trade specialist. Dispose of modules in accordance with the local disposal regulations.

Aluminum Frame

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.

8 Maintenance and cleaning

Qcells 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! 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.
0°

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.

Free the substructure from any dirt and debris (leaves, bird nests, etc.).
