Under normal conditions, a photovoltaic module is likely to experience conditions that produce more
currents and/or voltage than reported at standard test conditions. Accordingly, the values of ISC and
VOC marked on this module should be multiplied by a factor of 1.56 when determining component
voltage ratings, conductor ampacity, fuse sizes, and size of controls connected to the PV output.
Please refer to section 690-8 of the National Electrical Code (NEC) for any additional multiplying
factors of 156 percent, which may be applicable.
Installation should be in accordance with CSA C22.1, Safety Standards for Electrical Installations,
Canadian Electrical Code, Part 1.

Operating Environment
Climate Conditions
Install the PV module in the following conditions:
● Environment temperature: -20°C to 40 °C.
● Operating temperature: -40°C to 80 °C.
● Water resistance: Do not dip the modules into water or it will continually explode under water.
● Antisepsis: Keep away from salt erosions and sulfurous places.
Installation Notes
Modules’ electrical performance in a system is the same. In series connections, all modules must
have the same amperage. In parallel connections, all modules must have the same voltage. The
quantity of modules connected must match the voltage specifications of the devices used in the
system. Modules can not be connected to create a voltage that is higher than the permitted system
voltage.
In order to minimize the risk of an indirect lightning strike, avoid forming loops when designing the
system.
Modules must not be fitted as overhead glazing. Ensure that the installed system can withstand the
anticipated wind and snow loads.
2
The maximum load on the module must not exceed 1.44 kN/m . To avoid exceeding the maximum
load, site-specific environmental loads such as wind and snow should be accounted for.
Precipitations can run off through small openings on the back side of the module, which should not
be covered or blocked after installation.
The installed project must face north in the southern hemisphere, or south in the northern
hemisphere. The electricity will be comparatively lower when the project is facing west or east.
Incorrect installation will result in power loss.

Modules must be connected in the same angle. Otherwise, power loss will occur due to the
difference in sunlight intensity. Solar modules generate power to the maximum when facing directly
at the sun. When mounting modules to a permanent structure, modules should be tilted at an angle
for optimum winter performance. As a rule, if the system power output is adequate during the winter,
then performance will be satisfactory for the other seasons of the year. The module tilt angle is
measured between the solar modules and the ground.
Avoid installing modules under shadows, even module factories use bypass diodes to decrease the
loss of energy. Shadows will result in the loss of power output.
Grounding
All module frames must be attached to solid ground. A qualified electrician must complete ground
connections. The cable utilized in connecting modules to the ground must be copper wire with
14(12)AWG.

1. Copper wires with M5 cupped washer should be placed through the bolt.
2. Put the cut washer through the bolt. The bolt must be placed through the designated hole in
the aluminum frame.
3. Use the nut and the cut washer to secure all the parts. The copper wire can not be attached to
the aluminum.

Do not interrupt or manipulate the conductive connection during daily maintenances. All crunodes on
the conductive connection must be firmly attached. The fastness does not depend on soldering.
Suggested Maximum Number of Modules in Parallel and in Series
We recommend that the maximum number of modules in a parallel system should be no more than
four modules. The maximum number of modules in a series system should be no more than eight.
Mounting
Each module must be securely fastened at a minimum of 6 points (14 mm × 9 mm). The frame is
stress tested for mounting on the long sides. Its short sides should not be securing the module.
We recommend to use a torque wrench for installation. The tightening torque (using Stainless steel
M6 bolts, Stainless steel washer, and Stainless steel M6 nut) should be around 15-20 Nm. Modules
should be secured using existing holes. There is no need to drill any additional holes, which will
automatically void the product warranty. Appropriate corrosion-proof fastening materials should be
used.
An open space between the module frame and the mounting surface may be required to prevent the
junction box from touching the surface and to circulate cool air around the back of the module. We
recommend the standoff method or the rack method if the modules are installed on a rooftop or a
building wall. In the standoff method, the support for modules is parallel to the roof or building wall.
An open space is also required between the frame and the mounting surface to prevent wiring
damages and to allow air circulation to the back of the module. The recommended height for the
standoff method is 115 mm. If other mounting methods are employed, the Listing for Fire Class
Ratings may be affected.

Installation on the Rooftop
During rooftop and building wall installations, make sure that the modules are securely fastened. This
will prevent modules from falling down in extreme weather.
Please comply with safety standards and regulations and use the appropriate securing equipments.
The back sides of modules need to be sufficiently ventilated to prevent any hydrometeor.
A minimum distance of 50 mm needs to be observed between the installed planes and the back sides
of modules.
Wiring
The modules use TYCO 1740971-1 type junction box, located on the back side of the module. This
box is weather resistant and is compatible with standard wiring or conduit connections. Wiring
methods should be in accordance with the NEC. Each module is packed with a set of bypass diodes
and cable clamps.
● Correct Wiring Method
In order to minimize the risk of an indirect lightning strike, avoid forming loops when designing the
system. Check to make sure the wiring is correct before starting up the generator. If the measured
open circuit voltage (UOC) and short-circuit current (ISC) differ from the specifications, then there
is a wiring error.
● Correct Contact Plug Connections
The plug connector has its own polarity. Make sure that the connection is safe and secure. The
plug connector should not receive external stresses. Otherwise, it can only be used in circuit
connections.

● Use of Suitable Material
Use cable extensions and plugs that are intended for outdoor use. Ensure that they are in perfect
electrical and mechanical conditions. Use only cables that have one conductor. Select the
appropriate cable diameter to minimize voltage drop (to calculate the minimum cable diameter and
the fuse, and to calculate controls, multiply the UOC and ISC by a factor of 1.25).
If the module is connected to the control box, the control box with Female type Connectors TYCO
1394462-2 and Male type Connectors TYCO 1394461-4 must be used.
Bypass Diodes
The type, voltage rating, current rating of the diodes are SL1515, 40V, 16A, respectively. The
plastic material has an UL classification of 94V-0.
Partial shading of an individual module can cause reverse voltage to occur across the shaded
module. The electrical current is then forced through the shaded area by other modules.
When a bypass diode is wired parallel with the series string, the forced current will flow through the
diode and bypass the shaded module minimizing module heating and array losses of current.
Diodes used as bypass diodes:
Set a Rated Average Forward Current of 12A, above maximum system current at highest module
operating temperature.
Set a Rated Repetitive Peak Reverse Voltage 40V, above maximum system voltage at lowest
module operating temperature.
There are three bypass diodes per module and 20 cells per bypass diode
Battery
When charging batteries for solar modules, the battery must be installed in a proper manner to
protect system performance and user safety. Keep the battery away from any human and animal
traffic flows. Select a site that is well ventilated and protected from sunlight, rain, snow, and debris.
Do not light matches or create sparks near battery banks, as explosion causing hydrogen gas is
generated during the charging process. Outdoor installations of batteries should be in an insulated
and ventilated protective case intended for this purpose.
Maintenance and Cleaning
Do not change the PV components without consultation (diode, junction box, plug connectors, and
etc).
Give modules a sufficient tilt of at least 15°. Cleaning the modules is not necessary as rainfall will
produce a self-cleaning effect. Heavy soiling on modules will result in output reductions. Do not
scrape or rub away any dry soil accumulations, which will cause micro-scratch. We recommend
cleaning modules with plenty of water from a hose. Do not use any cleaning agents, the use of a
8
gentle cleaning application such as a sponge is sufficient. The system should be inspected at
regular intervals.
Checklists
● All connecting points are tight, secure, and free of corrosion.
● All cable connections are secure, tight, clean and free of corrosion.
● Cables should not be damaged in any manner.
● Check module frame’s conductivity to the earth.
Danger of Death from Electrical Shocks!
Solar modules generate electricity immediately after exposure to sunlight. A single module on its own
is below the extra low voltage safety level. When multiple modules are connected in series (adding up
the voltage) or in parallel (adding up the current), a potential danger is present. The following points
must be observed when handling the solar modules to avoid risks of fire, sparks, and fatal electric
shocks.
● Do not insert electrical conducting parts into plugs or sockets.
● Do not fit solar modules and wiring with wet plugs and sockets.
● Exercise utmost caution when carrying out work on wiring and safety equipments. Appropriate
protective gears should be used when applicable.
● Do not use modules if they are damaged in any manner. Do not dismantle modules. Do not mark
the rear of modules using sharp objects.
● Exercise utmost caution when working on wiring and the inverter. Be sure to follow manufacturer’s
installation instructions carefully.
● Artificially concentrated sunlight should not be directed at modules or panels at any time.
Danger of Death from Arcing!
Modules generate current under direct sunlight. An arc may be produced when connections are
separated. Thus, we recommend covering modules with a lightproof cloth during installation. When
breaking a connected string of modules (e.g. disconnecting the DC line from the inverter under load),
a lethally strong arc can occur:
● Never disconnect the solar generator from the inverter when the inverter is still connected to the
main grid—remove the fuse from the AC side on the inverter first.
● Ensure cable connections are in perfect condition (no splitting, soiling, or other contamination).
Remark: All sizes are measured in mm, with a tolerance of ±2 mm.
