Do not install or handle the modules when they are wet or during periods of high wind.
Do not use or install broken modules.
If the front glass is broken, or the back sheet is torn, contact with any module surface or the frame can cause
electric shock.
Keep the junction box cover closed at all times.
Do not attempt to repair any part of the module. There’re no serviceable parts within the PV module.
Do not disassemble a module or remove any module part.
Do not artificially concentrate sunlight on a module.
Do not connect or disconnect modules when current from the modules or an external source is present.
3.0 MECHANICAL / ELECTRICAL SPECIFICATIONS
The module electrical ratings are measured under Standard Test Conditions (STC) of 1 kW/m2irradiance with an
AM1.5 spectrum, and cell temperature of 25°C. The detailed electrical and mechanical characteristics of EDF
ENR PWT. crystalline silicon PV modules can be found in table A-2 of this manual (see Annex). Main electrical
characteristics at STC also appear on each module label. The maximum system voltage for all modules series is
either 600V or 1000V. Please refer to the datasheet or the product nameplate for the maximum system voltage.
Under certain conditions, a module may produce more current or voltage than its Standard Test Conditions (STC)
rated power. Accordingly, a module's open-circuit voltage and short-circuit current at STC should be multiplied
by 1.25 when determining component voltage ratings, conductor ampacities, overcurrent device ratings, and size
of controls connected to the PV output. An additional 1.25 multiplier for a short-circuit current (for a total of
1.56), for sizing conductors and fuses may be applicable, as described in section 690-8 of U.S. NEC.
3.1 DIODES

Do not change the wiring of bypass diodes.
Keep all electrical contacts clean and dry.
5.0 MODULE INSTALLATION
Precautions and General Safety
Before installing modules, contact the appropriate authorities for site, installation and
inspection permission and requirement.
Check applicable building codes to ensure that the construction or structure (roof,
facade, support, etc.) can withstand the module system load.
When installing the modules, please ensure the assembly is mounted over a fire resistant roof covering rated
for the application. EDF ENR PWT modules have been listed as Class C according to UL790 standard.
The fire rating of this module is valid only when mounted in the manner specified in the
mechanical mounting instructions.
CAUTION: In any case DO NOT STAND OR STEP on the modules, as localized high
loads may induce severe micro-cracks at the cell level, which in turn may compromise
module reliability. Failure to comply with above caution will void EDF ENR PWT
warranty.
Environmental conditions
The module is intended for use in general open climates, as defined in IEC 60721-2-1: Classification of
environmental conditions Part 2-1: Environmental conditions appearing in nature - temperature and

Do not immerse modules in water or constantly expose modules to water (either fresh or salt) (i.e. from
fountains, sea spray).
Exposing modules to salt (i.e. marine environments) and sulfur (i.e. sulfur sources, volcanoes) risks module
corrosion.
Requirements of installation
Ensure that the module meets the technical requirements of the system as a whole.
Ensure that other systems components do not exert damaging mechanical or electrical influences on the
modules.
Modules can be wired in a series to increase voltage or in parallel to increase current. To connect in series,
connect cables from the positive terminal of one module to the negative terminal of the next module. To
connect in parallel, connect cables from the positive terminal of one module to the positive terminal on the
next module.
Quantity of bypass diodes provided can vary depending on model series.
Connect the quantity of modules that match the voltage specifications of the inverters used in the system.
Modules must NOT be connected together to create a voltage higher than the permitted maximum system
voltage, even under the worst local temperature conditions.
Similar electrical performance modules should be connected in the same series to avoid or minimize
mismatch effects in arrays.
To minimize risk in the event of an indirect lightning strike, avoid forming loops when designing the
system.
The recommended maximum series fuse rating is tabulated in annex.
Modules should be firmly fixed in place in a manner suitable to withstand all expected loads, including
wind and snow loads. A minimum clearance of 6.5 mm (1/4 of an inch) or more between modules is
required to allow for thermal expansion of the frames.
Small openings for water draining on the underside of the module should not be blocked after mounting.
Optimum orientation and tilt
Find out the optimum orientation and tilt of the PV modules for your region to achieve the maximum annual
yield. Generation of maximum power occurs when sunlight shines perpendicularly onto the PV modules.
Avoid shading
Even the slightest partial shading (e.g., from dirt deposits) will cause a reduction in yield. A module is
considered "shadow-free" if it is unobstructed across its entire surface for the whole year. Even on the
shortest day of the year, unobstructed sunlight can reach the module.
Reliable ventilation
Sufficient clearance (at least 10 cm) between the module frame and the mounting surface is required to
allow for cooling air to circulate around the back of the module. This also allows for condensation or
moisture to dissipate.

5.1 MODULE WIRING
Correct wiring scheme
When designing the system, avoid forming loops (to minimize risk in the event of an indirect lighting
strike). Make sure that wiring is correct before starting up the system. If the measured open circuit voltage
(Voc) and short-circuit current (Isc) differ from the specifications, then there is a wiring fault.
Correct connection of plug connectors
Make sure that the connection is safe and tight. The plug connector should not receive outer stress. The
connector should only be used to connect the circuit. It should never be used to turn the circuit on and off.
Use of suitable materials
Use special solar cable and suitable plugs only (wiring should be placed in conduit that is sunlight-resistant
or, if exposed, should be sunlight-resistant) in accordance with local fire, building and electrical code.
Ensure that they are in perfect electrical and mechanical condition.
The permitted type of solar cable is single conductor cable listed and labeled as USE-2 or PV Wire, 90°C
wet rated, with proper insulation to withstand the maximum possible system open-circuit voltage. The
conductor material should use copper only. Select a suitable conductor gauge to minimize voltage drop and
ensure conductor ampacity complies with local regulations (such as NEC 690.8(D)).
Cable protection
Secure the cables to the mounting system using UV-resistant cable ties. Protect exposed cables from damage
with appropriate precautions (e.g. locate them within plastic conduit). Avoid exposure to the direct sunlight.
5.2 GROUNDING
A module with exposed conductive parts is considered to be in compliance with U1703 only when it is
electrically grounded in accordance with the instructions presented below and the requirements of the
National Electrical Code.
Although the modules are certified to safety class II, it is required that they be grounded. And the module
installation complies with all local electrical codes and regulations.
The earth grounding connection should be made by a qualified electrician.
Connect module frames to each other using suitable grounding conductor. Holes provided for this purpose
are identified with a grounding symbol.
Use 6-12 AWG (4-14 mm2) copper wire only. The bolts, nuts, flat washers, lock washers or other relevant
hardware should be made of stainless steel, unless otherwise specified.
Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers, flat washers and the
like) is used to attach a listed grounding/bonding device, the attachment must be made in conformance with
the grounding device manufacturer’s instructions.
Common hardware items such as nuts, bolts, star washers, lock washers and the like have not been
evaluated for electrical conductivity or for use as grounding devices and should be used only for
maintaining mechanical connections and holding electrical grounding devices in the proper position for
electrical conductivity. Such devices, where supplied with the module and evaluated through the

requirements in UL1703, may be used for grounding connections in accordance with the instructions
provided with the module.
All the junctions on the conductive connection must be fixed. Metal containing iron in the conductive
connection should be made with stainless steel or be treated against corrosion by anodizing, spray-painting,
or galvanization to prevent rusting and corrosion.
Grounding hardware is not provided by EDF ENR PWT.
One grounding method approved by North-American certification body (CSA) is recommended for
Photowatt modules, as described below. For alternative CSA qualified grounding methods, please refer to
Annex B.
Method: Bolt + Nut with teeth + Cup washer
When diameter of the grounding holes is 5mm (CSA certified).
A grounding kit with M5 size SS cap bolt, M5 size SS flat washer, M5
size SS cup washer, and M5 size SS nut (with teeth) is used to attach a
copper grounding wire to grounding hole pre-drilled on the frame (see
picture below).
Attach the wire between the flat washer and the cup washer. Ensure the
cup washer is between the frame and wire with concave side up to
prevent corrosion due to dissimilar metal. Tighten the bolt securely
using the SS nut with teeth. A wrench may be used in this application. The tightening torque is 1 Nm.

The mounting design must be certified by a registered professional engineer. The mounting design and
procedures shall comply with local electrical and building codes.
The module is considered to be in compliance with UL 1703 only when the module is mounted in the
manner specified by the mounting instructions below.
Mounting hardware is not provided by EDF ENR PWT.
EDF ENR PWT modules can be mounted to a support structure by several approved methods, either using
the mounting holes located on the back frame (see Example A), or by means of clamps (see Example B).
For other installation hardware, please contact your local representative for further information. Failure to
use a recognized installation method will void EDF ENR PWT warranty.
Only the bolting method has been qualified by all major North-American certification bodies (CSA, and
Intertek) during testing and listing of EDF ENR PWT modules according to UL1703 standard. For
inlay-systems or other installation hardware, please contact your local representative for further information.
Alternative mounting methods qualified internally by EDF ENR PWT are described in Annex C.
Example A: Example B:
Bolting (INTERTEK and CSA qualified) Clamping on (INTERTEK qualified)
Use appropriate corrosion-proof fastening materials. All mounting hardware (bolt/spring washer/flat
washer/nut) should be made with stainless steel M6 size for bolting method (A), and M8 size for clamping
method (B).
Use a torque wrench for installation. The above figure shows methods of fastening module to support
structure. Tightening torques should respectively be within 4~6 Nm and 10~17 Nm for M6x1 (Example A)
and M8x1.5 (Example B) coarse thread bolts, depending on bolt class. Different recommendations from
specific clamping hardware suppliers should prevail.
EDF ENR PWT modules can be installed in either landscape or portrait position, refer to the detailed
instructions (see table 6-1) for further guidance. Note that further countermeasures such the use of
additional support bars should be considered in heavy snow areas (> 2400 Pa), to avoid damage by the snow
accumulating in the lowest row of modules.
When the addition of a support bar is recommended to enhance mechanical stability and module long term
performance reliability, material of suitable resistance should be selected. EDF ENR PWT recommends a
minimum thickness of 50mm for the bar. The support bar centerline should be positioned within 100 mm of
the side frame centerline (slight shift may be necessary to access module grounding hole).
6.1 MOUNTING METHOD: BOLTING
Modules should be bolted to support structures through mounting holes located in the frame's back flanges
only. Do not drill additional holes or modify the module frame. Doing so will void the warranty.
Each module must be securely fastened at a minimum of 4 points on two opposite sides, using the most
inner mounting holes. If additional wind loads are anticipated for this installation, additional mounting

7.0 MAINTENANCE
Regular maintenance is required to keep modules clear of snow, bird droppings, seeds, pollen, leaves,
branches, dirt spots and dust.
If a module has a sufficient tilt (at least 150), it generally is not necessary to clean the modules (rainfall will
have a self-cleaning effect). When there is a noticeable buildup of soiling deposits on the module surface,
wash the PV array with water and a gentle cleaning implement (a sponge) during the cool part of the day.
Dirt must never be scraped or rubbed away when dry, as this will cause micro-scratches.
If snow is present, a brush with soft bristles can be used to clean the surface of the module.
Periodically inspect the system to make sure all wiring and supports stay intact.
If you need electrical or mechanical inspection or maintenance, it is recommended to have a licensed,
authorized professional carry out the job to avoid hazards of electric shock or injury.
Do not change the PV components (diode, junction box, plug connectors).

ANNEX B: ALTERNATIVE GROUNDING METHODS
All the requirements of paragraph 5.2 should apply to the alternative grounding methods. Each method has
been qualified by at least one North-American certification body, as specified.
For grounding methods A and B, connect module frames to each other using suitable grounding conductor
with ring terminals.
A copper terminal ring is recommended (please see below picture for reference). The d2 diameter should be
5.3mm and the size of d1 is determined by the size of the grounding cable. Proper crimping tool and method
should be used to crimp the terminal onto the grounding cable. Once crimped, each terminal should be
visually checked according to the following points:
1. The insulator jacket is correctly crimped in
the first collar
2. The conductor core is correctly crimped in
the second collar
3. The conductor core does not run over the
functional part of the ring terminal
4. The ring terminal should not be bent or
deformed during the crimping operation.
GROUNDING METHOD B: Bolt + K-nut + Ring terminal (copper)
When diameter of the grounding holes is 5mm
Connect the grounding hardware to the grounding hole on the frame as
shown in the picture.
A K-nut is used to penetrate the frame’s anodizing (protective
coating) to create conductive connection.
A torque moment of about 3Nm should be used to fasten the
grounding parts to module frame.
ANNEX C: ALTERNATIVE MOUNTING METHODS
All the requirements of paragraph 6.0 should apply to the alternative mounting methods, unless otherwise
specified.
C.1 MOUNTING METHOD A: CLAMPING
The mounting method has been qualified by EDF ENR PWT and certified by CSA.
Top or bottom clamping methods will vary and are dependent on the mounting structures. Follow mounting
guidelines recommended by the mounting system supplier.

Each module must be securely fastened at a minimum of 4 points on two opposite sides. The clamps should
be positioned according to the authorized position ranges defined in table C-1. Install and tighten the
module clamps to the mounting rails using the torque stated by the mounting hardware manufacturer.
System designer and installer are responsible for load calculations and for proper design of support
structure.
EDF ENR PWT warranty may be void in cases where improper clamps or unsuitable installation methods
are found. When installing inter-modules or end type clamps, take measures so as:
1. Not to bend the module frame
2. Not to touch or cast shadow on the front glass
3. Not to damage the surface of the frame
4. To ensure the clamps overlap the module frame
by at least 5 mm.
5. To ensure the clamps overlap length is at least
40 mm.
Clamp material should be anodized aluminum alloy. Floating type clamps are not authorized.
Clamp positions are of crucial importance for the reliability of the installation, the clamp centerlines must
only be positioned within the ranges indicated in table C-1, depending on the configuration and load.
For configurations where the mounting rails run parallel to the clamps installation side, precautions should
be taken to ensure the module frame (C-shape) overlap the rail by 15mm or more.
