INTRODUCTION
First thank you very much for choosing GRUPPOSTG PV modules!
This installation manual covers key electric and mechanical installation
information, so please understand such information before installing GRUPPOSTG
modules. In addition, this manual also covers some safety information that you
shall get familiar with. All contents in this manual are intellectual properties of
GRUPPOSTG which originates from long term of technical exploration and
experience accumulation of GRUPPOSTG.
This installation manual does not entail any explicit or implicit quality warranty and
does not stipulate on compensation schemes for losses, module damages or other
costs caused by or related to module installation, operation, utilization and
maintenance process. If patent rights or the third party rights are infringed by use
of modules, GRUPPOSTG will not take any responsibility. GRUPPOSTG reserves the
rights for modifying product manual or installation manual without notice in

such as electric law, building law and electric connecting requirements. These
regulations differ with different installation sites, such as building roofing
installation, vehicle-mounted application. Requirements may also differ with
installation system voltage, DC or AC. See specific clauses in local authorities.
General information
3.1 Module identification
Each module is pasted with 3 labels providing information below:
1. Nameplate: It describes product type, standard rated power, rated current, rated
voltage, open circuit voltage, short circuit current under testing conditions,
certification indicator, maximum system voltage, etc.
Installation Manual PV Modules High Power Half Cut 3

2. Current level label: Divide modules as per their optimal working current and
there are values:
H, M or L (H means the highest current level). The best practice is to install
modules with the same current level (such as H) in one strand in the process of
installation.
3. Serial No.: Each module has a unique serial number which is solidified inside the
module permanently and it can be seen from front top of the module. Each serial

3.2 Regular safety
Installation Manual PV Modules High Power Half Cut 4
GRUPPOSTG 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.
When the module is installed on roof, it is necessary to take the overall fire rating
of the finished structure as well as later overall maintenance into account. The
roofing PV system shall be installed after assessment by construction experts or
engineers and with official analysis results for the entire structure. It shall be
proved capable of supporting extra system bracket pressure, including PV module
weight.
For your safety, please do not work on the roof without safety protective measures
which include but not limited to fall protection, ladder or stair and personal
protective articles.
For your safety, please do not install or handle modules in unfavorable conditions
including butnot limited to strong wind or gust, damp or sandy roofs.

3.3 Electric performance safety
PV products will produce DC in the sunlight, so there may be electric shock or
burning when touching module connecting line metals. 30V DC voltage or higher
voltage can be fatal.
In case of no connected load or external circuits, modules can also produce
voltage. Please use insulation tools and wear rubber gloves when operating
modules in the sunlight.
PV modules doe not have switch. PV modules can only stop work when they are
kept from sunlight or covered by cloth, hard board or light-proof materials or when
front side of modules are placed on smooth and flat surfaces.
To avoid electric arc or electric shock hazards, please do not break down electric
connection in loaded conditions. Wrong connections will also lead to electric arc or
shock. Keep connectors dry and clean and make sure that they are in good
working condition. Do not insert other metals into the connectors or carry out
electric connection by whatever means.
Snow and water in surrounding environments will intensify light reflection and
lead to increase of current and output power. And module voltage and power will
increase under low temperature.
If module glass or packaging materials are damaged, please wear personal
protective articles and isolate modules from the circuit.
Working is only allowed in dry conditions by means of dry tools. Do not operate
when modules are wet unless you wear the proper electric shock protection
device. Please operate following the cleaning requirements in this manual when
cleaning modules.
3.4 Operation safety
Do not open GRUPPOSTG Package in transportation and storage process unless
the modules arrive at the installation site.
Do not damage the package and do not make packaged modules on pallet fall
directly.
Do not exceed the highest layer limit indicated on the packaging carton when
piling modules up. Put packaging carton in the ventilated, rain-proof and dry
places before unpacking of modules.
Open GRUPPOSTG’s packaging carton following unpacking instructions.
Do not hold the connecting box or wires to lift the entire module in any cases.
Do not stand or walk on modules.
Installation Manual PV Modules High Power Half Cut 5

Do not pile one module onto another.
To avoid glass damage, do not put heavy objects on module glass.
Be careful when placing modules on a surface and at corners in particular.
Do not try to unpack the module or remove nameplate or parts of modules.
Do not paint surface of modules or apply any other glues.
Do not damage, grad or scratch back film of modules.
Do not drill frame of modules, which may reduce frame loading capacity or lead
to frame corrosion.
Do not scratch anodic coating of aluminum alloy frame except for grounding
connection.
Scratch may lead to frame corrosion and reduce frame loading capacity. Do not
repair glass or modules whose back film is damaged on your own.
3.5 Fire safety
Installation Manual PV Modules High Power Half Cut 6
Please consult local laws and regulations before installing modules and abide by
requirements on building fire protection. Fire rating of GRUPPOSTG modules is
Type4 according to UL 1703.
The roof shall be coated with a layer of fireproof materials of such rating for roofing
installation and make sure that the back plate and the mounting surface are fully
ventilated.
Difference of roofing structures and installation modes will affect fireproof
performance of buildings. Improper installation may lead to fire disasters.
To guarantee roof fire rating, the module frame shall be at least 10cm from the roof
surface.
Adopt proper module accessories such as fuse, circuit breaker and grounding
connector according to local regulations.
The fire rating of this module is valid only when mounted in the manner specified
in the mechanical mounting instructions.
Please do not use modules if there are exposed inflammable gases nearby.
Installation conditions
4.1 Installation site and working environments
The modules can only be used on earth but not in outer space.
Do not focalize sunlight with mirrors or magnifying glass artificially onto modules.

GRUPPOSTG modules shall be installed on proper buildings or other appropriate
places (such as ground, garage, building outer wall, roof, PV tracking system) but
shall not be installed on any mobile vehicles.
Do not install modules at such places as that are possible to be submersed.
GRUPPOSTG suggests that modules be installed in the working environment with
the temperature of - 20 °C to 46 °C which is the monthly average highest and
lowest temperature of the installation places. The extreme working environment
temperature for modules is -40°C to 85 °C.
Make sure that installed modules do not suffer wind or snow pressure that exceeds
the permissible maximum load.
Modules shall be installed in places free from shades throughout the year. Make
sure there are no light-blocking obstacles in the installation places.
Carry out lightning protection for modules installed in places with frequent
lightning and thunder. Do not install modules in places with possible inflammable
gases.
Modules can not be used in environments with too much hails, snows, flue gas, air
pollution and soot or in places with strong corrosive substances such as salt, salt
mist, saline, active chemical steam, acid rain, or other substances corroding
modules, affecting module safety or performance.
Please take protective measures to ensure reliable and safe installation of modules
in severe environments such as heavy snow, cold and strong wind or islands close
to water and salt mist or deserts.
4.2 Selection of tilt angles
Tilt angle of modules: Included angle between module surface and horizontal
surface; the module will obtain the maximum power output in direct facing of
sunlight.
Modules are preferred to be south-facing in the north hemisphere and north-
facing in the south hemisphere.
A specific installation angle shall be determined according to installation guide for
standard modules or suggestions from PV module installer.
GRUPPOSTG suggests that module installation tilt angle be no less than 10° so
module surface dust can be washed away easily by rainfall and times of cleaning
can be reduced. And it is easy for ponding to flow away and avoid water print on
the glass due to long time of water ponding which may further affect module
appearance and performance.
Installation Manual PV Modules High Power Half Cut 7

Mechanical installation
5.1 Regular requirements
Make sure that module installation mode and bracket system are solid enough to
bear the expected load, which is requisite assurance that the bracket installer must
provide. Installation bracket system shall be tested and inspected by the third
party testing institution with static mechanical analysis capacity in accordance
with local national or international standards.
Module bracket shall be made from durable, corrosion resistant, ultraviolet proof
materials. Modules shall be fixed on the bracket solidly.
Use higher brackets in places with heavy snow accumulation so the lowest point of
modules will not be covered by snow for a long time. In addition, make the lowest
point high enough so as to avoid sheltering of vegetations and woods or damage
of flying sands and stones.
If modules are installed on brackets parallel to the roof or wall, the minimum gap
between the module frame and the roof/wall shall be 10cm for air ventilation so as
to prevent module line damage.
Do not make holes on glass or frame of modules.
Make sure the building is suitable for installation before installing modules on roof.
Moreover, seal permeable parts properly to prevent leakage.
The module frame has thermal expansion and cold contraction so the frame
interval between two adjoining modules shall be less than 10mm.
Make sure that back plate of modules will not contact bracket into the module or
building structures, especially when the module surface is imposed by pressure.
GRUPPOSTG Solar Modules have been certified for a maximum design static load
on the back of the Modules of up to 1600Pa*1.5 (i.e. wind load) and a maximum
design static load on the front of the Modules of up to 3600Pa*1.5 (i.e. wind and
snow load), depending on the clamp mounting (please refer to follow installing
data for this information). And this is printed on the label of modules.
Module installation methods can not lead to electrochemical corrosion between
module aluminum frame and different metals. Electrochemical potential
difference of contacting metals shall not exceed 0.6V as is recommended in UL1703
Appendix Flat Plate Photovoltaic Modules and Panels.
Modules can be installed horizontally or vertically.
Installation Manual PV Modules High Power Half Cut 8

5.2 Way of installation
Module and bracket system connection can be realized by clamp or embedded
systems. Installation shall follow the demonstration and suggestions below. If
installation mode is different, please consult GRUPPOSTG and obtain approval.
Otherwise, modules may be damaged and quality warranty will become invalid.
5.2.1 Use clamps to install modules
Use the special clamp to install modules. See Figure 3.
A. Fix the modules on the support profiles using metal clamps. The following
clamps or those clamps recognized by module system installer are recommended.
Width: no less than 40mm;
Thickness: no less than 3mm;
Material: aluminum alloy;
Bolt: no less than M6.
B. Torque range for bolt fastening: 18N•m to 24N•m
C. The clamp shall not contact glass or make module frame deformed in any case.
The contacting surface of the clamp and frame front side shall be neat and
smooth. Otherwise, frame and module may be damaged. Make sure that the clamp
will not produce shading effect. Drain holes can not be sheltered by the clamp.

5.2.2 Position of installation connecting points
Low/normal load working condition applies to most environments: the
maximum static load for backside is 1600Pa*1.5 (equal to wind pressure) and the
maximum static pressure for the front side is 1600Pa*1.5 (for 4 clamps
installation) (equal to wind pressure and snow pressure).
Higher load applies to severe environments (such as wind storm, heavy snow):
the maximum static load for backside is 1600Pa*1.5 (equal to wind pressure) and
the maximum static pressure for the front side is 3600Pa*1.5 (for 6 clamps
installation) (equal to wind pressure and snow pressure).
Electric installation
6.1 Electric performance
Module electric performance parameters such as Isc, Voc and Pmax nominal values
have ±3% error with those under standard testing conditions of: irradiance of 1000
W/m2, cell temperature of 25°C and air mass of AM1.5.
Under normal conditions, a photovoltaic module is likely to experience conditions
that produce more current and/or voltage than reported at standard test
conditions. The requirements of the National Electrical Code (NEC) in Article 690
shall be followed to address these increased outputs. In installations not under the
requirements of the NEC, the values of Isc and Voc marked on this module should
be multiplied by a factor of 1.25 when determining component voltage ratings,
conductor ampacities, overcurrent device ratings, and size of controls connected to
the PV output.
When modules are in series connection, the final voltage is sum of that of the
single module. When modules are in parallel connection, the final current is sum of
the single module. See Figur 5.

1500V
The number of modules in series connection in each strand shall be calculated as
per requirements. The open circuit voltage value under the expected lowest
temperature shall not exceed the maximum system voltage value stipulated for
modules (GRUPPOSTG module maximum system voltage is DC1500V according to
UL 1703) and other values required by DC electric parts.
Maximum series overcurrent protective device, where required.
If there is reverse current exceeding the maximum fuse current flowing through
the module, use overcurrent protection device with the same specifications to
protect the module; if parallel connection strands are more than 2, there shall be
an overcurrent protection device on each strand of module. See Figure 5.
6.2 Cables and connecting lines
In module design, adopt enclosed connecting boxes with the protective level of
IP68 for on- site connection to provide environmental influence protection for
wires and connections and contacting protection for non-insulating electric parts.
The connecting box has well connected cables and connectors with the protective
level of IP68. These designs facilitate parallel connection of modules. Each module
has two independent wires connecting the connecting box, one is negative pole
and the other is positive pole. Two modules can be in parallel connection by
inserting the positive pole at one end of wire of one module into the negative pole
of the adjoining module.
Cables connecting modules shall satisfy the module maximum short circuit
current. Adopt the special PV system sunlight resistant cables.
The minimum standards of cables connecting modules are:
When cables are fixed on the bracket, avoid mechanical damage to cables or
modules. Do not press cables by force. Adopt special designed light resistant wires
and clamps to fix cables on the bracket. Though cables are light resistant and
water proof, it is still necessary to prevent cables from direct sun radiation and
water immersion.
6.3 Connector
Please keep connectors clean and dry. Make sure connector nuts are fastened
before connection. Do not connect connectors that are damp or dirty or under
other status. Protect connectors from direct sun radiation and water immersion or
fall onto ground or roof.
Wrong connection may lead to electric arc and electric shock. Please make sure
that all electric connection is reliable. Make sure all connectors with lock are fully
locked.
Installation Manual PV Modules High Power Half Cut 13

6.4 Bypass diode
GRUPPOSTG solar module connecting box contains bypass diode which is in
parallel connection with the cell strands. If heat spot occurs locally with the
module, the diode will come into operation to stop the main current from flowing
through the heat spot cells with the view to restrain module heating and
performance loss. But bypass diode is not the overcurrent protection device.
If the diode is found or doubted to get out of order, the installer or system
maintenance supplier shall contact GRUPPOSTG. Please do not try to open the
module connecting box on your own.
Grounding
In design of modules, the anodized corrosion resistant aluminum alloy frame is
used for rigidity support. For safety utilization and to protect modules from
lightning and static-electricity damage, the module frame shall be grounded.
The grounding device shall be in full contact with inner side of the aluminum alloy
and penetrate the frame surface oxide film.
Do not drill additional grounding holes on module frame.
To get the optimal power output, GRUPPOSTG suggests that DC negative pole of
the module array shall be grounded in installation of modules. Otherwise, the
system power output will be reduced.
Module installation methods can not lead to electrochemical corrosion between
module aluminum frame and different metals. Electrochemical potential
difference of contacting metals shall not exceed 0.6V as is recommended in UL1703
Appendix Flat Plate Photovoltaic Modules and Panels.
Holes on the frame shall be drilled in advance and grounding signs shall be
indicated. These holes are only used for grounding but not for installation of
modules.
A module with exposed conductive parts is considered to be in compliance with
UL1703 only when it is electrically grounded in accordance with the instructions
presented below and the requirements of the National Electrical 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
manufacturer’s instructions.
GRUPPOSTG recommends must thoroughly detail the attachment means in the
module installation instructions.
Installation Manual PV Modules High Power Half Cut 14

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.
Grounding methods below are permissible:
7.1 Grounding by grounding clamp
There is a grounding hole with the diameter of Ø4.2mm at the edge of the module
back frame. The central line of the grounding sign and that of the hole overlaps
and is consistent with the frame length direction.
Grounding between modules shall be confirmed by qualified electricians and
grounding devices shall be manufactured by qualified electric manufacturer. The
torque is recommended to be 2.3N•m.
12 AWG copper core wire is used for the grounding clamp. And copper wires can
not be pressed damaged in installation.
Installation Manual PV Modules High Power Half Cut 15

Figure 6 Grounding Clamp Installation
Note: TYCO. 1954381-1 (recommended) is used in figures above.
7.2 Grounding by unoccupied mounting holes
Mounting holes on modules that are not occupied can be used for installing
grounding devices.
1.Align grounding clamp to the frame mounting hole. Use grounding bolt to go
through the grounding clamp and frame.
2.Put the tooth side of the washer on the other side and fasten the nuts. The
recommended torque for nut fastening is 2.0Nm to 2.2Nm.
3.Put grounding lines through the grounding clamp and grounding wire material
and dimension shall meet requirements in local national and regional law and
regulations.
4.Fasten bolts of grounding lines and installation ends.

Figure 7 Way of Installation
7.3 The third party grounding devices
The third party grounding device can be used for grounding of GRUPPOSTG
modules but such grounding shall be proved to be reliable. Grounding device shall
be operated in line with stipulations of the manufacturer.
Operation and maintenance
Carry out regular inspection and maintenance for modules and this is the user’
responsibility within the quality warranty period in particular; and, inform the
supplier within two weeks when modules are found to be damaged.

Installation Manual PV Modules High Power Half Cut
8.1 Cleaning
Accumulated dust on module surface glass will reduce the power output and lead
to local heat spot, such as industrial waste water and birds droppings. The degree
of influence is determined by transparency of wastes. Small amounts of dust will
affect sunlight strength and evenness but are not dangerous and power will not be
reduced remarkably in general.
During operation of modules, there shall be no environmental factors projecting
shades or shelter partial or the entire module, including other modules, module
system bracket, birds, dust, soil or plants. These will reduce output power.
GRUPPOSTG suggests that the module surface should not be sheltered in any
case.

Frequency of cleaning depends on dirt accumulation speed. In normal situations,
rainwater will clean the module surface and the cleaning frequency is reduced
therefore. It is suggested to use damp clean water sponge or soft cloth to wipe the
glass surface. Do not use acid and alkaline detergents to clean modules.
8.2 Module appearance inspection
Module glass cracks.
Corrosion at welding parts of the cell main grid: it is caused by moisture into the
module due to damage of surface packaging materials during installation or
transportation.
Check whether there is burning traces on the module back plate.
Check module appearance defects visually, especially:
1.
2.
3.
8.3 Inspection of connectors and cables
Check connector sealing and cable connection solidness.
Check whether sealant of the terminal box is cracking with gap.
It is suggested to carry out a preventive inspection once every 6 month:
