understood. PV module connectors pass direct current
(DC) when exposed to sunlight or other light sources.
Contact with electrically active parts of the module, such
as terminals, can result in injury or death, irrespective of
whether or not the module and the other electrical
equipment have been connected.
Avertissement
Toutes les instructions devront être lues et
comprises avant de procéder à l’installation,
le câblage, l’exploitation et/ou l’entretien des panneaux.
Les interconnexions des panneaux conduisent du courant
continu (CC) lorsque le panneau est exposé à la lumière
du soleil ou à d’autres sources lumineuses. Tout contact
avec des éléments sous tension du panneau tels que ses
bornes de sortie peut entraîner des blessures ou la mort,
que le panneau soit connecté ou non.
General Safety
All modules must be installed by licensed electricians in
accordance to the applicable electrical codes such as, the
latest National Electrical Code (USA) or Canadian Electric
Code (Canada) or other national or international
applicable electrical codes.
Protective clothing (non-slip gloves, clothes,
etc.) must be worn during installation to
prevent direct contact with 30 V DC or
greater, and to protect hands from sharp
edges.
Prior to installation, remove all metallic
jewelry to prevent accidental exposure to
live circuits.
When installing modules in light rain,
morning dew, take appropriate measures
to prevent water ingress into the
connector.

Do not allow children or unauthorized
persons near the installation site or
module storage area.
Do not install modules in strong wind.
Use electrically insulated tools to reduce the risk of
electric shock.
If the disconnects and over current protection devices
(OCPDs) cannot be opened or the inverter cannot be
powered down, cover the fronts of the modules in the
PV array with an opaque material to stop the
production of electricity when installing or working on
a module or wiring.
Do not use or install damaged modules
Contact with module surfaces or frames may cause
electric shock if the front glass is broken or the
backsheet is torn.
The PV module does not contain any serviceable parts.
Do not attempt to repair any part of the module.
Keep the junction box cover closed at all times.
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.
2.1 INFORMATION PURSUANT TO ART. 33 OF
THE REACH REGULATION
Pursuant to Art. 33 of Regulation (EC) No 1907/2006 of the
European Parliament and of the Council of 18 December
2006 concerning the Registration, Evaluation,
Authorisation and Restriction of Chemicals (REACH),
establishing a European Chemicals Agency, amending
Directive 1999/45/EC and repealing Council Regulation
(EEC) No 793/93 and Commission Regulation (EC) No
1488/94 as well as Council Directive 76/769/EEC and
Commission Directives 91/155/EEC, 93/67/EEC, 93/105/EC
and 2000/21/EC (the “REACH Regulation”), we inform you
that our solar modules contain a Substance of Very High
Concern (“SVHC”) in a concentration above 0.1 % (weight
by weight).
The copper ribbons used in our solar modules to
interconnect solar cells use a thin solder coating layer that
contains lead (CAS no. 7439-92-1).
Under normal or reasonably foreseeable conditions of
use, exposure to the lead that is contained in our solar
modules can be excluded. However, a release of, and
exposure to, lead can take place (i) when the different
components of the solar modules are disassembled, in
particular for recycling purposes, and (ii) in instances of
fire. Lead may damage fertility or the unborn child, causes
damage to organs through prolonged or repeated
exposure, is very toxic to aquatic life with long lasting
effects, may cause cancer, is very toxic to aquatic life, and
may cause harm to breast-fed children.
Therefore, recycling and all other types of comparable
disassembly of the solar modules have to be performed
by a qualified waste management company, in
compliance with national and local waste management
regulations.
In the instance of fire, please keep away from the fire, and
call the local fire brigade.
3.0 MECHANICAL / ELECTRICAL
SPECIFICATIONS
Module electrical ratings are measured under Standard
Test Conditions (STC) of 1000 W/m2 irradiance, with an
AM1.5 spectrum, and a cell temperature of 25°C. Detailed
electrical and mechanical characteristics of Canadian
Solar crystalline silicon PV modules can be found in Annex
A (Module Specifications) on www.csisolar.com. Main
electrical characteristics at STC are also stated on each
module label. 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 rated
power. As a result, the module short-circuit current under
STC should be multiplied by 1.25, and a correction factor
should be applied to the open-circuit voltage (see Table 1
below), when determining component ratings and
capacities. Depending on your local regulations, an
additional 1.25 multiplier for the short-circuit current
(giving a total multiplier of 1.56) may be applicable when
sizing conductors and fuses.

Alternatively, a more accurate correction factor for the
open-circuit voltage can be calculated using the following
formula:
𝐂Voc = 𝟏 − 𝜶𝑽𝒐𝒄 × (𝟐𝟓 − 𝐓)
T is the lowest expected ambient temperature at the
system installation site.
αVoc is the voltage temperature coefficient of the selected
module (refer to corresponding datasheet).
Electrical calculations and design must be performed by a
competent engineer or consultant.
Please contact Canadian Solar’s technical support team
for additional information pertaining to engineering
optimization and approval of project specific module
string lengths.
4.0 UNPACKING AND STORAGE
PRECAUTIONS
Modules should be stored in a dry and ventilated
environment to avoid direct sunlight and moisture. If
modules are stored in an uncontrolled environment,
the storage time should be less than 3 months and
extra precautions should be taken to prevent
connectors from being exposed to moisture or sunlight,
like using connector endcaps.
Unpack module pallets carefully, following the steps
shown on the pallet. Unpack, transport and store the
modules with care.
Modules must always be unpacked and installed by two
people. Always use both hands when handling modules.
Do not lift modules by their wires or junction box, lift
them by the frame.
Stacks of modules should contain no more than 12
modules, and the frames should be aligned.
Do not place excessive loads on the module or twist the
module frame.
Do not stand, step, walk and/or jump on modules
under any circumstances. Localized heavy loads may
cause severe micro-cracks at cell level, which in turn
may compromise module reliability and void Canadian
Solar’s warranty.
All manuals and user guides at all-guides.com

EN-Rev IM/GN-RM-EU/1.21P Copyright © June, 2021. CSI Solar Co., Ltd. www.csisolar.com
Do not support the module by the backsheet when
handling or installing the module.
Do not carry modules on your head.
Do not drop or place objects (such as tools) on the
modules.
Do not use sharp instruments on the modules.
Particular care should be taken to avoid module
backsheets being damaged by sharp objects, as
scratches may directly affect product safety.
Do not leave modules unsupported or unsecured.
Do not change the wiring of bypass diodes.
Keep all electrical contacts clean and dry at all times.
Do not expose the modules and its electrical contacts
to any unauthorized chemical substance (e.g. oil,
lubricant, pesticide, etc.).
PRODUCT IDENTIFICATION
Each module has three identical barcodes (one in the
laminate under the front glass, the second on the rear
side of the module and the third on the frame) that act as
a unique identifier. Each module has a unique serial
number containing 13 (pre-March 2013) or 14 (post-
March 2013) digits.
A nameplate is also affixed to the rear of each module.
This nameplate specifies the model type, as well as the
main electrical and safety characteristics of the module.
5.0 MODULE INSTALLATION
PRECAUTIONARY MEASURES AND
GENERAL SAFETY
Prior to installing modules please obtain information
about any requirements and necessary approvals for
the site, installation and inspection from the relevant
authorities.
Check applicable building codes to ensure that the
construction or structure (roof, facade, support, etc.)
can bear the module system load.
Canadian solar modules have been qualified for
Application Class A (equivalent to Safety Class II
requirements). Modules rated under this class should
be used in systems operating at voltage above 50V or
power above 240W, where general contact access is
anticipated.
Canadian Solar modules have been certified as Type 1
or Type 4 according to UL 1703, Type1 or Type 2
according to UL 61730 and Class C according to IEC
61730-2 for fire class performance, please refer to the
datasheet or the product nameplate for the detailed
types.
Consult your local authority for guidelines and
requirements for building or structural fire safety.
UL 1703 SYSTEM FIRE RATING REQUIREMENTS
Photovoltaic systems composed of UL 1703 or UL 61730
certified modules mounted on a UL 2703 certified
mounting system should be evaluated in combination
with roof coverings in accordance with UL 1703 or UL
61730 standard, with respect to meeting the same fire
classification as the roof assembly.
Mounting systems with a System Fire Class Rating
(Class A, B or C), tested in conjunction with “Type 1” or
“Type 2” or “Type 4” fire rated modules, are considered
acceptable for use with Canadian Solar modules,
provided that the mounting system does not violate any
other requirements of this manual.
Any mounting system limitations on inclination or
accessories required to maintain a specific System Fire
Class Rating should be clearly specified in the
installation instructions and UL 2703 certification of the
mounting system supplier.
When installing modules, ensure the assembly is
mounted over a fire resistant roof covering rated for the
application.
The fire rating for this module is only valid when the
product is installed as specified in the mechanical

mounting instructions.
ENVIRONMENTAL CONDITIONS
The module is intended for use in general open-air
climates, as defined in IEC 60721-2-1: Classification of
environmental conditions Part 2-1: Environmental
conditions appearing in nature. Temperature and
humidity.
Please consult the Canadian Solar technical support
department for more information on the use of
modules in special climates, such as an altitude greater
than 2000m.
Do not install modules near open flames or
flammable materials.
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) or
sulfur (i.e. sulfur sources, volcanoes) incurs the risk of
module corrosion.
Do not expose modules and their connectors to any
unauthorized chemical substances (e.g. oil, lubricant,
pesticide, etc.), as modules may incur damages.
Canadian solar modules have passed salt mist
corrosion resistance test according to IEC 61701, but
the corrosion may still occur on where the modules
frame is connected to the bracket or where the
grounding is connected. Should the installation location
be near the ocean, Canadian solar recommends
stainless steel or aluminum materials be used in the
areas with direct contact with the PV modules, and the
connection point should be protected with anti-
corrosion measures. For more information, please
contact Canadian solar technical support team.
Failure to comply with these instructions will void
Canadian Solar warranty.
INSTALLATION REQUIREMENTS
Ensure that the module meets the general technical
system requirements.
Ensure that other systems components do not damage
the module mechanically or electrically.
Modules can be wired in series to increase voltage or in
parallel to increase current. To connect modules in
series, connect the cables from the positive terminal of
one module to the negative terminal of the next module.
To connect in parallel, connect the cables from the
positive terminal of one module to the positive terminal
on the next module.
The quantity of bypass diodes in the module’s junction
box provided may vary depending on the model series.
Only connect the quantity of modules that corresponds
to the voltage specifications of the inverters used in the
system. In addition modules must not be connected
together to create a voltage higher than the maximum
permitted system voltage stated on the module
nameplate, even under the worst local temperature
conditions (see Table 1 for the correction coefficients
that apply to open-circuit voltage).
A maximum of two strings can be connected in parallel
without using an over-current protection device (fuses,
etc.) incorporated in series within each string. Three or
more strings can be connected in parallel if an
appropriate and certified over-current protection
device is installed in series within each string. And it
shall be ensured in the PV system design that the
reverse current of any particular string is lower than the
module maximum fuse rating at any circumstances.
Only modules with similar electrical parameters should
be connected in the same string to avoid or minimize
mismatch effects in arrays.
To minimize risk in the event of an indirect lightning
strike, avoid forming loops with the wiring when
designing the system.
The recommended maximum series fuse rating is
stated in a table in the Annex A.
Modules should be safely fixed to bear all expected
loads, including wind and snow loads.
A minimum clearance of 6.5 mm (0.25 in) between
modules is required to allow for thermal expansion of
the frames.
The small drainage holes on the underside of the
module must not be blocked.
All manuals and user guides at all-guides.com

EN-Rev IM/GN-RM-EU/1.21P Copyright © June, 2021. CSI Solar Co., Ltd. www.csisolar.com
OPTIMUM ORIENTATION AND TILT
To maximize the annual yield, please calculate the
optimum orientation and tilt for PV modules in that
specific installation site. The highest yields are achieved
when sunlight shines perpendicularly onto the PV
modules.
AVOID SHADING
Even minor partial shading (e.g. from dirt deposits)
reduces yields. A module can be considered to be
unshaded if its entire surface is free from shading all
year round. Sunlight should be able to reach at least the
module even on the shortest day of the year.
Constant shading conditions can affect module service
lifetime, due to accelerated ageing of the encapsulation
material and thermal stress on the bypass diodes.
RELIABLE VENTILATION
Sufficient clearance (at least 102 mm (4.02 in)) between
the module frame and the mounting surface is required
to allow cooling air to circulate around the back of the
module. This also allows condensation or moisture to
dissipate.
According to UL 1703, any other specific clearance
required for maintaining a system fire rating should
prevail. Detailed clearance requirements pertaining to
system fire ratings must be provided by your racking
supplier.
5.1 MODULE WIRING
CORRECT WIRING SCHEME
Cable management scheme should be reviewed and
approved by the EPC contractor; in particular required
cable lengths should be cross-checked considering the
specificities of the tracker structure like bearing house
gaps. If longer cable or additional jumper cable is
requested, please contact Canadian Solar’s sales
representative in advance.
Ensure that the wiring is correct before starting up the
system. If the measured open circuit voltage (Voc) and
short-circuit current (Isc) differ from the specifications,
this indicates that there is a wiring fault.
When modules have been pre-installed but the system
has not been connected to the grid yet, each module
string should be kept under open-circuit conditions and
proper actions should be taken to avoid dust and
moisture penetration inside the connectors.
Do not connect different connectors (brand and model)
together.
The maximum distance between two adjacent module
frames should be within 50 mm (1.96in) for the side
with mounting clamps, and within 25 mm (0.98in) for
the side without mounting clamps, in order to meet the
system cable scheme.
CORRECT CONNECTION OF PLUG CONNECTORS
Make sure that all connections are safe and properly
mated. The PV connector should not be subject to stress
from the exterior. Connectors should only be used to
connect the circuit. They should never be used to turn
the circuit on and off.
Connectors are not waterproof when unmated. When
installing modules, connector should be connected to
each other as soon as possible or appropriate measures
(like using connector endcaps) should be taken to avoid
moisture and dust penetrating into the connector.
Do not clean or precondition the connectors using
lubricants or any unauthorized chemical substances.
USE OF SUITABLE MATERIALS
Only use dedicated solar cable and suitable connectors
(wiring should be sheathed in a sunlight-resistant
conduit or, if exposed, should itself be sunlight-
resistant) that meet local fire, building and electrical
regulations. Please ensure that all wiring is in perfect
electrical and mechanical condition.
Installers may only use single-conductor cable listed
and labeled as USE-2 or PV wire which is 90°C wet rated
in North America, and single conductor cable, 2.5-16
mm² (5-14 AWG), 90°C wet rated in other areas (i.e. TUV
2PfG1169 or EN50618 approved), with proper
insulation which is able to withstand the maximum
possible system open-circuit voltage.
Only copper conductor material should be used. Select
All manuals and user guides at all-guides.com

EN-Rev IM/GN-RM-EU/1.21P Copyright © June, 2021. CSI Solar Co., Ltd. www.csisolar.com
a suitable conductor gauge to minimize voltage drop
and ensure that the conductor ampacity complies with
local regulations (i.e. NEC 690.8(D)).
CABLE AND CONNECTOR PROTECTION
Secure the cables to the mounting system using UV-
resistant cable ties. Protect exposed cables from
damage by taking appropriate precautions (e.g. placing
them inside a metallic raceway like EMT conduit). Avoid
exposure to direct sunlight.
A minimum bending radius of 60 mm (2.36 in) is
required when securing the junction box cables to the
racking system.
Protect exposed connectors from weathering damage
by taking appropriate precautions. Avoid exposure to
direct sunlight.
Do not place connectors in locations where water could
easily accumulate.
5.2 GROUNDING
For grounding requirements in North America, a
module with exposed conductive parts is considered to
comply with UL 1703 only when it is electrically
grounded in accordance with both the instructions
presented below and the requirements of the National
Electrical Code. Any grounding means used with
Canadian Solar modules should be NRTL certified to UL
467 and UL 2703 standards. Please consult our
technical service team for the formal approval process.
For grounding requirements in other areas, although
the modules are certified to Safety Class II, we
recommend them to be grounded and that module
installation should comply with all applicable local
electrical codes and regulations. Grounding
connections should be installed by a qualified
electrician. Connect module frames together using
adequate grounding cables: we recommend using 4-14
mm² (AWG 6-12) copper wire. Holes provided for this
purpose are identified with a grounding symbol
(IEC 61730-1). All conductive connection junctions
must be firmly fixed.
Do not drill any extra ground holes for convenience as
this will void the modules warranty.
All bolts, nuts, flat washers, lock washers and other
relevant hardware should be made of stainless steel,
unless otherwise specified.
Canadian Solar does not provide grounding hardware.
The grounding method described below is
recommended for Canadian Solar.
GROUNDING METHOD: BOLT + TOOTHED NUT + CUP WASHER.
A grounding kit containing an M5 (3/16") SS cap bolt, an
M5 (3/16") SS flat washer, an M5 (3/16") SS cup washer,
and an M5 (3/16") SS nut (with teeth) is used to attach
copper grounding wire to a pre-drilled grounding hole
on the frame (see image above).
Place the wire between the flat washer and the cup
washer. Ensure that the cup washer is positioned
between the frame and the wire with the concave side
up to prevent galvanic corrosion. Tighten the bolt
securely using the SS toothed nut. A wrench may be
used to do this. The tightening torque is 3-7 Nm (2.2-5.2
ft-lbs).
To fix the wire between the
flat washer and cup washer,
place the cup washer
(concave side up) between
the frame and the wire.
Then tighten the bolt
using the toothed nut.

6.0 MOUNTING INSTRUCTIONS
The applicable regulations pertaining to work
safety, accident prevention and securing the
construction site must be observed. Workers
and third party personnel shall wear or install fall arrest
equipment. Any third party need to be protected against
injuries and damages.
The mounting design must be certified by a registered
professional engineer. The mounting design and
procedures must comply with all applicable local codes
and requirements from all relevant authorities.
The module is considered to be in compliance with UL
1703 or UL 61730 and IEC 61215 only when the module
is mounted in the manner specified by the mounting
instructions included in this installation manual.
The system designer and installer are responsible for
load calculations and for proper design of support
structure.
Any module without a frame (laminate) shall not be
considered to comply with the requirements of UL 1703
or UL 61730 unless the module is mounted with
hardware that has been tested and evaluated with the
module under this standard or by a field Inspection
certifying that the installed module complies with the
requirements of UL 1703 or UL 61730.
Canadian Solar does not provide mounting hardware.
Classic modules can be mounted onto a support
structure using one of several approved methods as
described below. For information about other
installation methods, please contact your local
representative. Failure to use a recognized installation
method will void the Canadian Solar warranty.
Use appropriate corrosion-proof fastening materials.
All mounting hardware (bolts, spring washers, flat
washers, nuts) should be hot dip galvanized or stainless
steel.
Use a torque wrench for installation.
Do not drill additional holes or modify the module
frame. Doing so will void the warranty.
Classic modules can be installed in either landscape or
portrait orientations. Refer to the detailed instructions
for further guidance. Please note that in areas with
heavy snowfall (> 2400 Pa) further countermeasures
such the use of additional support bars should be
considered to avoid snow loads damaging the lowest
row of modules.
In cases where an additional support bar is
recommended to improve both mechanical stability
and long-term module performance, we recommend
selecting a sufficiently resistant material. Canadian
Solar recommends bars with a minimum thickness of
50 mm (1.97 in). The support bar centerline should be
positioned within 100 mm (3.94 in) of the side frame
centerline (slight shifts may be necessary to access
module grounding holes).
The loads described in this manual correspond to test
loads. For installations complying with IEC 61215-
2:2016 and UL 1703 or UL 61730, a safety factor of 1.5
should be applied for calculating the equivalent
maximum authorized design loads. Project design
loads depend on construction, applicable standards,
location and local climate. Determination of the design
loads is the responsibility of the racking suppliers
and/or professional engineers. For detailed
information, please follow local structural code or
contact your professional structural engineer.
6.1 MOUNTING METHOD: BOLTING
The mechanical load test with these mounting methods
were performed according to IEC 61215.
Modules should be bolted to supporting structures
through the mounting holes in the rear frame flanges
only.
Each module must be securely fastened at a minimum
of 4 points on two opposite sides.

6.2 MOUNTING METHOD: CLAMPING
The mechanical load test with these mounting methods
were performed according to IEC 61215.
Top or bottom clamping methods will vary and are
dependent on the mounting structures. Please follow
the mounting guidelines recommended by the
mounting system supplier.
Each module must be securely fastened at a minimum
of four points on two opposite sides. The clamps should
be positioned symmetrically. The clamps should be
positioned according to the authorized position ranges.
Install and tighten the module clamps to the mounting
rails using the torque stated by the mounting hardware
manufacturer. M8 X 1.25 (5/16”) bolt and nut are used
for this clamping method.
Tightening torques should be within 16~20 Nm
(11.8~14.75 ft-lbs) for M8 (5/16”) coarse thread bolts,
depending on the bolt class. For the bolt grade, the
technical guideline from the fastener suppliers should
be followed. Different recommendations from specific
clamping hardware suppliers should prevail.
The system designer and installer are responsible for
load calculations and for proper design of support
structure.
Canadian Solar’s warranty may be void in cases where
improper clamps or unsuitable installation methods are
found. When installing inter-modules or end-type
clamps, please take the following measures into
account:
1. Do not bend the module frame.
2. Do not touch or cast shadows on the front glass.
3. Do not damage the surface of the frame (to the
exception of the clamps with bonding pins).
4. Ensure the clamps overlap the module frame by at
least 5mm (0.2in).
5. Overlap in length by at least
a) 80 mm (3.15 in) when uplift load > 2400 Pa is
required.
b) 40 mm (1.57 in) when uplift load ≤ 2400 Pa is
required.
6. Ensure the clamp thickness is at least 3 mm (0.12 in).
Clamp material should be anodized aluminum alloy or
stainless steel.
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
below, depending on the configuration and load. For
configurations where the mounting rails run parallel to
the frame, precautions should be taken to ensure the
bottom flange of the module frame overlaps the rail by
15 mm (0.59 in) or more.

7.0 MAINTENANCE
Do not make modifications to any component of the PV
module (diode, junction box, connectors or others).
Regular maintenance is required to keep modules clear
of snow, bird droppings, seeds, pollen, leaves, branches,
dirt spots, and dust.
Modules with sufficient tilt (at least 15°), generally may
not require cleaning (rain will have a self-cleaning
effect). If the module has become soiled, wash with
water and a non-abrasive cleaning implement (sponge)
during the cool part of the day. Do not scrape or rub dry
dirt away, as this may cause micro scratches.
Snow should be removed using a soft brush.
Periodically inspect the system to check the integrity of
all wiring and supports.
To protect against electric shock or injury, electrical or
mechanical inspections and maintenance should be
performed by qualified personnel only.
8.0 MODULE CLEANING GUIDELINES
This manual covers the requirements for the cleaning
procedure of Canadian Solar‘s photovoltaic modules. The
purpose of these cleaning guidelines is to provide general
information for cleaning Canadian Solar modules. System
users and professional installers should read these
guidelines carefully and strictly follow these instructions.
Failure to follow these instructions may result in death,
injury or damage to the photovoltaic modules. Damages
induced by inappropriate cleaning procedures will void
Canadian Solar warranty.
SAFETY WARNING
Cleaning activities create risk of damaging the modules
and array components, as well as increasing the
potential electric shock hazard.
Cracked or broken modules represent an electric shock
hazard due to leakage currents, and the risk of shock is
increased when modules are wet. Before cleaning,
thoroughly inspect modules for cracks, damage, and
loose connections.
The voltage and current present in an array during
daylight hours are sufficient to cause a lethal electrical
shock.
Ensure that the circuit is disconnected before starting
the cleaning procedure as contact with leakage of
electrically active parts can result in injury.
Ensure that the array has been disconnected to other
active components (such as inverter or combiner boxes)
before starting with the cleaning.
Wear suitable protection (clothes, insulated gloves, etc.).
Do not immerse the module, partially or totally, in
water or any other cleaning solution.
HANDLING NOTICE
Use a proper cleaning solution and suitable cleaning
equipment.
Do not use abrasive or electric cleaners on the
module.
Particular attention should be taken to avoid the
module backsheet or frame to come in contact with
sharp objects, as scratches may directly affect product
safety.
Do not use abrasive cleaners, de-greasers or any
unauthorized chemical substance (e.g. oil, lubricant,
pesticide, etc.) on the module.
Do not use cleaning corrosive solutions containing
hydrofluoric acid, alkali, acetone, or industrial alcohol.
Only substances explicitly approved by Canadian Solar
are allowed to be used for cleaning modules.
Canadian Solar recommends to avoid rotating brush
cleaning methods, as they could create micro-cracks in
the PV modules.
Dirt must never be scraped or rubbed away when dry,
as this will cause micro-scratches on the glass surface.
OPERATION PREPARATION
Noticeable dirt must be rubbed away by gentle cleaning
implement (soft cloth, sponge or brush with soft
bristles).
All manuals and user guides at all-guides.com

EN-Rev IM/GN-RM-EU/1.21P Copyright © June, 2021. CSI Solar Co., Ltd. www.csisolar.com
Ensure that brushes or agitating tools are not abrasive
to glass, EPDM, silicone, aluminum, or steel.
Conduct the cleaning activities avoiding the hottest
hours of the day, in order to avoid thermal stress on the
module.
We recommend the following to be used:
Water with low mineral content
Near neutral pH water
The maximum water pressure recommended is 4 MPa
(40 bar)
CLEANING METHODS
Method A: Compressed Air
Canadian Solar recommends cleaning the soft dirt (like
dust) on modules just with air pressure. This technique
can be applied as long as the method is efficient enough
considering the existing conditions.
Method B: Wet cleaning
If excessive soiling is present on the module surface, a
non-conductive brush, sponge, or other mild agitating
method may be used with caution.
Ensure that any brushes or agitating tools are
constructed with non-conductive materials to minimize
risk of electric shock and that they are not abrasive to
the glass or the aluminum frame.
If grease is present, an environmental friendly cleaning
agent may be used with caution.
