3. Warning notices and handling instructions
Warning notices
ATTENTION:
Danger of death from electric shock
Solar modules start to generate electricity as soon as they are exposed to light. Solar panels can produce life
threatening High voltage! especially when connected in series.
The fully insulated plug-in contacts do provide
insulation protection. However, you should nevertheless
observe the following when handling photovoltaic modules:
• Do not insert electrically conductive parts into the plugs and sockets.
• Do not install solar modules and wiring with wet plugs and sockets. Working conditions and tools must be dry.
• All work performed on the wiring must be carried out by authorized specialist personnel with the utmost
caution and only with the aid of safety equipment.
• High voltages may be present in wiring, modules and inverters even when they are switched off. Undertake all
work with the appropriate level of caution – risk of death due to electric current!
• After switching off the inverter, before beginning any further work it is essential to wait for the time interval
specified by the manufacturer so that the high-voltage components can discharge.
• Be sure to carefully follow the inverter manufacturer’s installation instructions!
WINAICO modules are designed to meet the requirements for the IEC 61215, IEC 61730 and UL 1703 standards for
operation in a temperate climate (the module operating temperatures are between -40 °C and +85 °C). Hazardous
voltages (IEC 61730: higher than 50V DC; EN61730: higher than 120V DC),
hazardous power applications (higher than
240W) where general unrestricted access is anticipated. Modules qualified
for safety through EN IEC 61730-1 and
61730-2 within this application class are considered to meet the requirements
for Safety Class II).
ATTENTION:
Danger of death from electric arcs
Modules generate direct current (DC) when exposed to light irradiation and a deadly electric arc
can result when
opening a closed section (e.g. when separating the DC cable from the inverter under
load).
Product protection
Protect the modules from incorrect handling.
• Do not lay any objects on the modules, never walk on the modules and do not drop them.
• Only undertake modifications on the module if these have been confirmed in writing by WINAICO.
• Do not work on the modules with pointed objects.
• Keep all electrical contacts clean and dry.
• It is recommended that the serial numbers be noted for system documentation.
• The solar module is not saltwater-resistant, and shall not be in direct contact with salt water.
• The module must not be subjected to unusual chemical loads (e.g. emissions from manufacturing plants).
• Do not use lenses or mirrors to concentrate light (danger of overheating).
• If solar modules are to be connected to storage batteries, the safety precautions of the battery manufacturer
must be observed.
• Do not stand or step on the PV module, this is prohibited. There can be risk of micro-crack which may cause a
sharp decline of module’s power performance; what’s more, it may threaten your safety.
• Do not hit or put excessive load on the glass or back sheet. There can be risk of micro-crack which may cause a
4

SIM2002-01(EN)
sharp decline of module’s power performance; what’s more, it may threaten your safety.
Under the anticipated conditions, a PV module can supply a higher current and/or voltage than specified in the
standardised test conditions. The voltage rating of components, current rating values of conductors, fuse sizes and
rating of controllers connected to the outputs of PV modules should be at least 1.25 times the module Isc and Voc. For
systems installed in North America, refer to Section 690-8 of the National Electrical Code for an additional 1.25
multiplying factor where applicable. The highest rating value for the overcurrent protection (reverse-current strength)
is 20 A.
4. Module Handling
Safety
•A pallet of solar panels weighs over 600kg
•Solar panels weigh up to and over 20kg, and at over 1.5m long can be cumbersome to handle. Care should be
taken to avoid injury
•It is hazardous to install solar panels in high wind conditions
•It is hazardous to install solar panels in wet weather
General
Take care when transporting and handling solar panels. Many issues caused by rough handling will arise years after the
installation. Taking additional care can save considerable time and money from avoided service calls and replacements.
•It is recommended that you inspect all deliveries immediately to ensure there have not been any issues during
transit. If there are any problems contact WINAICO immediately
•Never walk on a solar module or place or drop a heavy object onto one
•Modifications or repairs must be confirmed by WINAICO in writing
•Keep all electrical contacts clean and dry
•Do not work on the modules with sharp objects
•Record module serial numbers for system documentation
Transport
•Transport vehicles and equipment should
be fit for purpose and well maintained
•Secure boxes in transit to avoid collisions
or impacts during transportation
•Treat boxes and pallets with care, do not
drop or allow the boxes to receive impacts
•Any other freight being transported with Solar Modules should be properly secured to prevent impacts
•Any panels transported outside of their boxes should be properly secured and not allowed to move
independently
Storage
•Store in a cool dry place. The cardboard
box while strong is not waterproof
•WINAICO Pallets can be stacked once on
top for storage. Do not stack more than
two pallets high
•Leave modules in packaging until they are
ready for install

SIM2002-01(EN)
Unpacking
• Unpacking is a two people job
• Lift the 1st module vertically with both hands to avoid frame scraping
• Avoid horizontal movement when lifting module.
• Carry the modules with both hands and wear safety gloves or use glass
suction cups for removal and transport.
• Under no circumstances use the junction box or connection lines as
handles.
5. Application area and mounting site
Application area
• The module is intended for use in temperate climatic conditions. The extreme weather temperature might affect
the power output and efficiency of the solar module.
• The module must not be exposed to concentrated light. It must not be immersed in water or constantly
exposed to water spray (e.g. from fountains).
• There is risk of corrosion with exposure to salt and sulfur (sulfur sources, volcanoes). Therefore, the
module must not be installed in the vicinity of salt, salt water and sulfur.
• The permissible module temperatures are between -40 °C and +85 °C.
• Sufficient ventilation from behind the module should be ensured to prevent raised module temperatures.
• Do not subject modules to strong chemicals.
• Make sure that the modules and module components are never standing or lying in water.
• The module may not be installed adjacent to naked flames or flammable materials. Solar modules are non-
explosion-protectedequipment.
Mounting site
• Orientation
The performance of WINAICO Panels is dependent on the available solar resource, as well as their positioning in
relation to the movement of the sun. Optimal panel tilting will be determined by the installation location, local
siting restriction, and the load profile or desired generation profile. Your local WINAICO office can assist with
optimum system design.
A minimum tilt of 15 degrees is recommended to allow for water and dirt run off. Tilt angles less than this are
permitted if additional maintenance is planned to keep the panels clean, and a proper design analysis has been
completed.
• Location
The mounting site should be as free as possible from shade of any kind (houses, trees, branches, leaves, cables,
antennas, etc.), because shade can significantly reduce the output of the solar modules. Partial shade can also
reduce the energy yield. A module is regarded as free of shade if the entire surface is free of shade throughout
the year, and with unhindered exposure to sunlight over a period of several hours per day, even on the most
unfavorable days of the year.
• Ventilation from behind
Solar modules decrease in power output as their temperature increases. Ventilation from behind allows air
convection to cool the module, with greater spacing increasing the cooling rate. This is particularly import for
modules with black backsheets and for flush mounting.
WINAICO recommends that modules be mounted with a minimum of 120mm clearance from a flat surface.
6

SIM2002-01(EN)
• Winter
When mounting a module it is essential to ensure that the water drainage openings on the rear side of
the frame are not covered of the
module are not covered, in order to avoid damage from frost. The solar
installation should be mounted such
that as little snow as possible can remain on the modules. Solar
modules from WINAICO are certified for snow
loads up to 5400 Pa.
6. Mounting and installation
ATTENTION:
Risk of fire if module components are damaged!
• Only install undamaged solar modules.
• Before the installation ensure that the junction box, cables and connectors are undamaged.
• Never open the junction box chassis.
Safety precautions
• Store the modules safely in cool and dry rooms. The packaging is not weather-proof!
• Incorporate the installation in the existing lightning protection system in line with local requirements.
• WINAICO recommends only mounting and installing the system in dry weather.
• Observe the relevant accident prevention regulations.
• Do not carry out installation work in high winds.
• Secure yourself and other persons against falling.
• Prevent the possibility of falling objects.
• Secure the work area so that no other persons can be injured. Keep children away from the installation site.
• All parts of the module should be protected from mechanical stress (e.g. caused by pressure, tension, torsional
stress) during transport and installation. Ensure that the radius doesn't fall below the minimum permissible
bend radius of 60 mm for cables at the junction box output either during installation or system operation.
• Do not damage, pull, bend, or place heavy material on cables.
Fire protection
The installation of on-roof systems can affect the fire safety of a building; improper installations can be a fire hazard. In
the case of on-roof applications, the WINAICO modules must be mounted above a fire-resistant surface.
The module is “non-explosion-protected equipment”. The use of improper installation methods and/or defective parts
may result in the unexpected occurrence of an electrical arc during operation. Therefore, it may not be installed near
highly flammable gases and vapors (e.g. filling stations, gas tanks or paint spraying systems). The module may not be
installed adjacent to naked flames or flammable materials.

SIM2002-01(EN)
6.1 Mechanical module mounting
WINAICO modules are suitable for both vertical and horizontal installation methods due to their high degree of stability.
The modules must be clamped in place at a minimum of 4 points. The modules are always installed with the junction
box pointing upwards, such that the junction box is located on the rear side of the module in the
upper section.
Examples of incorrect installations:
Reverse installation with junction box
pointing downwards, are not suggested.
Examples of correct mounting methods: clamps and mounting with screws.
The modules can be mounted on the substructure by clamps from the front or by screws from behind. The clamping
area (Figure below) for each fastening point must have an area of at least 135 mm2. A torque wrench must be used for
assembly. In the examples shown, the tightening torque (using M8 bolts produced from V2A) is 20 Nm. Use the existing
drilled holes for securing the module. Do not drill any additional holes (doing so will void the product warranty). Use
appropriate corrosion-resistant fastening materials and use washers to fasten the PV module.
When the aluminum frame is mounted on a bracket of different metal material, the two metal parts should be isolated
to avoid galvanic corrosion, especially for humid or coast areas.

SIM2002-01(EN)
Maximum mechanical load
Ensure that the maximum mechanical load is not exceeded, also taking into account any site-dependent loads (See
Chapter 2. PRODUCT DESCRIPTION). Please note that the module can bend under heavy loads. Do not use cable ties or
other fastening
elements on the rear side of the module, because uneven structures can damage the modules.
Note
The middle clamps can be used as spacers between the module rows when mounting the modules. To avoid any
possible stresses and failure to comply with dimensions, a gap should be maintained between the module rows. We
recommend a gap of approximately 2 cm. For aesthetic reasons we recommend using black clamps for mounting our
module series with black anodized frame and black backsheet. Do not touch live terminals with bare hands, and always
use insulated tools for electrical connections.
Laying the cables
To avoid conductor loops, the strings (+ and –) should be laid together. Cable trays can be used if required. Roof
penetration should be minimized to one if possible. PVC cables are not recommended. Bare copper H07RN cables are
not recommended because the contact resistance of crimping location will probably exceed the permitted value as the
copper wires oxidise over time. WINAICO recommends installers should use certified solar cables (EN 50618: 2014) for
direct
current (DC) wiring in PV systems. The minimum wire size should be 12 AWG.
ATTENTION:Lightning protection is recommended for PV systems that are to be installed in
locations with high
probability of lightning strikes.
6.2 Electrical installation
Module selection
Ensure the module meets the technical requirements of the system as a whole. Ensure that other system components
do not exert damaging mechanical or electrical stresses on the module. When connected in series, modules must all
have the same current rating. When connected in parallel, the modules must all have the same voltage rating. The
modules must not be connected together to create a voltage higher than the permitted system voltage. Ensure that the
mounting system can also withstand the
anticipated loads, e.g. wind and snow loads. There are openings at the base
of the module frame to allow water from
precipitation to drain away. Ensure that the functionality of these openings is
not restricted by the module installation.
Diodes and fuses
The shading of individual solar cells or solar modules can lead to the shaded area heating up as it begins to consume
electrical energy, as opposed to generating. The use of bypass diodes to bridge the shaded areas results in a
reduction in the heating process, and mitigates the
performance losses of the respective PV system. WINAICO
solar modules are factory-fitted with integrated bypass
diodes or other design elements, which offer efficient
protection to the solar cells. Please be noted that the bypass diodes are not overcurrent
protection devices.
As per IEC 62446-1, the installation of additional blocking diodes or fuses is necessary with the parallel connection of
module strings because the
integrated bypass diodes are only for module internal protection and do not regulate the
current flow in a
parallel circuit in the event of the shading or defect of individual module strings. A failure to comply
may result in the
corresponding solar modules (including the electronic components contained within them) being
damaged.
10

WINAICO is a trademark of Win Win Precision Technology Co., Ltd.
www.winaico.com
SIM2002-01(EN)
WINAICO recommends the DC fuse should be used in each module string, in order to protect the solar modules in the
event of a malfunction (e.g. an inverter defect). The fuses must be configured according to the
maximum series fuse
rating, which is quoted in the data sheets pertaining to the respective modules.
Cables and connectors
A PV module has a pair of male and female waterproof connectors.
• Connect the output cable to the other equipment in the system correctly.
• Connect the required number of PV modules to meet the voltage specification of other equipment used in the
PV system.
• Wire the output cable connectors so they do not exert any force or pressure on the PV module’s junction box.
Attach the cable to the mounting frame using approved fasteners. The connectors should be placed behind the
mounting frame so that the connectors can’t be directly exposed to sunlight, wind and rain.
• To extend the cable, use certified solar cables and connectors that can withstand outdoor use for long
periods. Select the appropriate cable size according to its length to avoid voltage drop.
• Connectors of different brands and models cannot be mated.
ATTENTION: WINAICO connectors’ protection level is IP68. They cannot be under water for a long time.
Sunlight
exposure and immersion in water of the connectors should be avoided. Do not allow installed
PV connectors and
cables to be in contact with the roof surface or the ground.
ATTENTION: Faulty connections can result in arcs and electrical shock. Check that all electrical
connections are
securely fastened. Make sure that all locking connectors are fully engaged and locked.
ATTENTION:
To prevent electric shocks, please turn off the power when installing PV connectors. Do not pull apart
the PV connector under load. Turn off the DC/AC inverter or turn on DC circuit breaker to disconnect PV
connectors
from load. Then insert and extract under voltage is permitted.
ATTENTION:
The cable must not be bent or crushed at the joints to connectors and junction box. A minimum bending
radius R≥5×cable diameter must be maintained. The cable must be routed in a way that tensile
stress on the
conductor or connection is prevented.

SIM2002-01(EN)
Safety precautions
ATTENTION:
Please ensure the correct connection of the sockets and sleeves.
Do not cut the module cable connectors. The strings (+ and – cables) are fed into the inverter via the DC solar inputs.
The polarities of the module connectors are specified. The cable on the + connector of the module should be connected
to the inverter at the + input. The same procedure applies to the – connector and – inverter input. The cables can lie in
cable trays. It is important to make sure that no water remains in the cable trays. Holes can be drilled into the trays to
facilitate drainage. Only certified socket connectors can be used to connect the
solar cables to the modules and
inverters. The inverters should be
connected in accordance with the manufacturer’s instructions.
ATTENTION:
Depending on design requirements and inverter used, different string lengths are possible. It is essential
to follow the assembly instructions for the inverter! Make sure each individual string is de-energised prior
to connecting to the inverter. It is absolutely imperative that the inverter is connected to the public grid
power by a certified specialist.
ATTENTION:
High voltage direct current can occur even at low levels of radiation. Never touch exposed live cables.
6.3 Grounding
Proper grounding on the module frames is the responsibility of the solar installer. Grounding must be performed by an
authorised installer for the safety and maintenance of the system in accordance with all national, state and local
electrical codes and regulations and standards.
Proper grounding is achieved by connecting the module frame(s) and structural members contiguously using a suitable
“grounding conductor”. Careful selection of the grounding components dictates that when using connecting different
materials together, they shall not lead to galvanic corrosion of one another. As such, when using copper hardware,
contact with the aluminium frame shall be avoided. For North American customers, the grounding conductor, or strap,
may be copper, copper alloy, or other materials acceptable for use as an electrical conductor per NEC. The grounding
conductor must then make a connection to earth using a suitable earth ground electrode.
If an external lightning protection system is already provided or planned for the building, the photovoltaic system must
be integrated into the system to protect against direct lightning strikes. The grounding hole is marked on the module
frame.
12

WINAICO is a trademark of Win Win Precision Technology Co., Ltd.
www.winaico.com
SIM2002-01(EN)
For grounding purposes, an M4 stainless screw, nut and washer are used. PV modules have an anodized coating on
aluminium frames for corrosion resistance. In order to properly ground the modules frames, the coating must be
penetrated. Please observe the national standards when grounding. If national standards do not require grounding,
WINAICO still recommends all PV module frames to be grounded to ensure the voltage between the exposed metal
parts (ex. frame) and earth ground is zero in all circumstances.
When installing in North America, a module with exposed conductive parts is considered to be in compliance with UL
1703, only when it is electrically grounded in accordance with the instructions presented above and the requirements
of the National Electric Code. 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 of 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 UL 1703, may be used for grounding connections in accordance with the instructions provided with the
module.

7. Cleaning and maintenance
As the operator, you should regularly remove dirt from the modules and check if all system components are functioning
properly. The following points should be noted:
• Never stand on the module surface. Do not exert any mechanical load on the modules.
• Do not clean with water if there is a risk of frost or major differences in temperature between the module,
water and air.
• We recommend decalcifying hard water. This will prevent lasting water stains. Remove standing water from
the module.
• Do not use abrasive cleaning agents or detergents. Do not scrape off dirt as this may damage the surface of the
module.
• Check if all cables and connector accessories are undamaged and properly secured.
• PV modules are not shaded by unwanted obstacles or any foreign material.
• Mounting and grounding components are tightly secured with no corrosion.
ATTENTION:
Please make sure that the earth connection is not interrupted or damaged!
ATTENTION: WINAICO recommends PV systems to be periodically inspected by the installer, or
other qualified
person.
8. Liability disclaimer
These installation and assembly instructions apply in general to standard systems. No responsibility is accepted for the
correctness of this information. WINAICO does not provide any guarantee of the usability and serviceability of the
modules if the user fails to observe this user information. As compliance with this user information and the conditions
and methods for the installation, operation, use and maintenance of the modules from WINAICO cannot be checked or
