2. Safety instructions
General safety instructions
Repair and operation of a PV system require sound expert
knowledge. Therefore, all work on the system may only
be carried out by appropriately qualied and authorised
technical specialists. It is essential to read these moun-
ting instructions carefully and attentively before installing,
commissioning or maintaining the PV system, and keep
the instructions easily accessible. Non-observance of the
safety instructions can lead to personal injury and
damage to property. Keep children away!
We are constantly striving for the further improvement of
our products through innovation and research activity.
We therefore reserve the right to change the information
contained in this mounting manual without prior notice.
Applicable safety regulations
The modules of the system may only be used in accordan-
ce with their suitability. The modules may not be techni-
cally modied. During mounting, make sure that the locally
applicable building regulations, standards and accident
prevention regulations are observed. Ensure that the ne-
cessary safety instructions for mounting and operation of
other system components are also followed.
Using the modules
Please note the following points in particular when using
our solar modules:
+The installation and/or operation of the solar modules
is permitted up to a max. altitude of 2000 m above sea
level.
+e function of the modules is tested at an ambient
temperature of -40 to +85°C. This range should be
observed.
+The modules must not be exposed to exceptional
chemical loads (e.g. emissions from manufacturing
companies)
+When connecting solar modules to power storage-
units, the respective safety instructions of the
manufacturer must be observed.
Attention: Danger to life!
Danger to life from electric shock!
Solar modules generate electricity. If they are exposed
to light, they are live and can pose a danger. Even if the
voltage of a single module is still low at less than 50 V DC,
the total voltage adds up as soon as several modules are
connected in series.
When several modules are connected in parallel, the cur-
rents add up. Although the fully insulated plug contacts
provide protection against accidental contact, the follo-
wing must be observed when handling the solar modules
to avoid re, sparking and, above all, fatal electric shock:
+Do not insert electrically conductive parts into the plugs
and sockets
+Do not wear metal jewellery during mechanical and
electrical installation work.
+Do not wear metal jewellery during mechanical
and electrical installation work.
+Keeep moisture away from tools and the working
environment. Only install solar modules and cables
with dry plugs and sockets
+ Proceed with extreme caution and care.
+ Only use insulated tools to carry out all work on the ca
bles and also wear insulated gloves.
+Do not disassemble modules. Never remove parts or
type plates attached by the manufacturer. Only use
faultless modules. Do not use sharp objects, paints
or adhesives on the back of the module.
+ Do not expose solar modules to articially concentra-
ted sunlight.
Please note that the wiring of modules may only be
carried out by qualied and authorised specialists.

Transport, intermediate storage and safe
unpacking
The modules are sensitive technical components that re-
quire great care when handled. Be especially careful, there-
fore, when transporting and temporarily storing the modu-
les and leave them in their packaging until they are used.
Always lift and carry the modules with both hands and do
not use the junction box as a hand grip.
Do not drop the modules or place them roughly on hard
ground or on the module corners. Do not place objects on
the modules. Do not stack modules on top of each other
without protection.
Avoid bending the modules. Do not step on the modules.
Do not work with sharp objects and keep all electrical con-
tacts clean and dry.
If intermediate storage of the modules is necessary, a dry,
ventilated room should be provided.
Clean, non-slip gloves must be worn during all transport
and installation work to prevent injury from cuts on module
edges. In addition, avoid soiling the solar glass with nger-
prints, as they can damage the special coating of the glass.
It is essential to observe the warnings on the packaging
and the enclosed unpacking instructions
Danger to life due to high voltage!
Highcontactvoltagescanstilloccurintheinverterevenwhen
it is disconnected. For this reason, the following applies:
+Exercise extreme caution when working on the inverter
and the cables.
+In order for the high-voltage components to discharge,
it is essential to observe the time intervals specied by
the inverter manufacturer after switching off the inver-
ter and before starting any further work. Always observe
the mounting instructions of the inverter manufacturer.
Danger to life from electric arc!
When exposed to light, solar modules produce direct cur-
rent. If a closed circuit is opened, e.g. when the DC line is
disconnected from the inverter under load, a fatal electric
arc can occur.
+Under no circumstances disconnect the solar genera-
tor from the inverter as long as it is connected to the
mains.
+ Ensure awless cable connections.
+Connect cables seamlessly and keep them free from
dirt.
Electrical installation
The solar modules are designed for use in PV systems of
application class A and can therefore be operated in sys-
tems with dangerous direct voltages (greater than 120 V
DC according to EN 61730) and power ratings.PV modules
of this application class may be used in systems with un-
limited accessibility.
Solar Factory GmbH modules of the Mono S4, Mono S3,
Mono S2, M and P series, which are qualied within this
application class according to EN 61730, meet the require-
ments of protection class II when installed in accordance
with regulations.

purpose, earthing holes are provided on the back of the
module frame.
These earthing holes are marked with a stamped earthing
symbol.
3. Installation of the module
Ensuring safe installation
Secure yourself and other persons against falls; do not car-
ry out installation work in strong winds and prevent objects
from falling if possible. Carefully secure the working area
to avoid danger or injury to persons.
Always comply with the permissible maximum
mechanical load in accordance with DIN EN
1991-1-3/DIN EN 1991-1-4
Ensure that the maximum mechanical load is not exceeded
and take into account any location-dependent loads such
as wind or snow. Remember that the module could bend
under high load.
When using fastening elements, cable ties or comparable
connecting materials between the back of the module and
the cross proles, ensure that the module is not damaged
by pointed or uneven structures.
Ensuring that the modules are properly earthed
In accordance with the provisions of Solar Fabrik GmbH, it
is not necessary to earth the module frames and rack for
trouble-free operation. To avoid the risk of electric shock
(e.g. from static charges) as far as possible, Solar Fabrik
GmbH recommends having the installer carry out profes-
sional earthing.
If an external lightning protection device is available, a
technical specialist must integrate the PV system in the
lightning protection concept while observing country-spe-
cic standards and regulations
A qualied electrician must check the earthing connec-
tions between the modules. A qualied electrician must
also connect the main earthing.
An earthing method approved by Underwriters Laborato-
ries (UL) is mandatory in the USA and Canada. For proper

Correct handling of AR glass modules
The nano-porous coating on the glass surfaces of the solar
module reduces reection losses. Compared to uncoated
glass, a deviation of the irradiation angle from the vertical
can result in an angle-dependent transmission of up to 2
% more power. To maintain this effect and to avoid visual
impairments, we urgently recommend observing the follo-
wing instructions:
+Handle the modules with care due to the coated glass.
+Handle the modules with care when unpacking
and mounting. We recommend only touching
the surfaces with clean gloves because the
special reective properties make light soiling
easier to detect. Especially grease and oil are
visible even in small quantities and can inuence the
transmission.
+We advise against attaching stickers or labels
to the coated surface. Depending on the material used,
this can result in very ne residues
that are dicult to remove.
+In rare cases, there may be visible white residues of
the coating uid and colour variations
in the edge area (≤ 5 mm). These are fully functional
modules and there is no reduction in
quality.
+ If it is necessary to clean the modules due to
heavy soiling, we recommend the following
procedure:
+ Clean the modules when they have cooled down
(e.g. during the morning hours)
+ For moderate to strong residues, we recommend
cleaning with lukewarm, de-mineralised water and
clean, lint-free cotton cloths, microbre cloths or
paper towels
+ For particularly heavy and stubborn soiling, we
recommend detergents containing surfactants
+ Avoid cleaning with strong acids, alkaline solutions,
petrol-based cleaners, steam and hot cleaners, clea
ners with silicone oils, uorides or waxes,
polishes, alkaline cleaners and cleaners with scou-
ring agents and high-pressure cleaners.
+
This so-called anti-reective coating is subject to
coating tolerances, making the colour image of the
individual module different; this is most noticeable
in diffuse light.
Conrmation can be made that the anti-reective
coating may result in increased power yields and is
not a negative quality feature.
The phenomenon of optical differences should get
better after the rst few years of yield due to clima-
tic conditions, meaning that the system can be
operated in combination with these modules
without any reservations .
Technical Explanation of the cell production
process used in the manufacture of solar
modules
+The cells we use in the production of our panels are
classied as ‚A-Grade‘ cells without exception. Howe-
ver, the cell sorting process is undertaken both manu-
ally and mechanically. This can already lead to hetero-
geneous cell colours, which become visible through a
black backing lm.
+The cells used are both 166mm x 83mm and 182mm
x 91mm Mono Perc P-Type Halfcut cells or TOPCon N-
Type Halfcut cells. These module cells were subjected
to a coating thickness tolerance, this process can also
result in differences in colour.
+The cells were also treated with plasma-enhanced
chemical vapour deposition (PECVD) during the pro-
duction process. This separation process guarantees
improvements in eciency. However, it can also result
in differences in colour within the blue colour family.
Consequently, module cells may be light blue to grey
colour.
Independent of these processes, Solar Fabrik modules are
tested again by an independent test laboratory. Here, the
electro luminescence shows the desired quality characte-
ristics. This guarantees worry-fee operation.

Ensuring comprehensive re protection
Under certain circumstances, the installation of roof-
mounted systems can have an impact on the re safety of
a building. Improperly executed installations in particular
can lead to a re hazard. As the modules are not explosi-
on-proof equipment, do not install the modules near highly
ammable gases and vapours, e.g. in the vicinity of gas
containers, paint spraying systems or lling stations. Also,
do not install the modules next to naked ames and am-
mable materials.It is important that the installation always
complies with local conditions, laws and regulations.
Ensuring a suitable environment
The modules are primarily intended for use in moderate
climatic conditions. Make sure they are not exposed to ar-
ticially concentrated sunlight, submerged or continuously
exposed to splashing water at their destination. There is a
risk of corrosion if the modules are subject to exceptional
loads of salts or sulphur.
Suitable installation situation
It is of utmost importance that the module meets the tech-
nical requirements of the overall system. Therefore, make
sure that no damaging mechanical or electrical effects
(e.g. overvoltage) are exerted on the module by other sys-
tem components. When connected in series, only modules
of the same amperage may be used; when connected in
parallel, only modules with the same voltage may be used.
The modules may only be operated with the permissible
system voltage; operation with a higher voltage is not in-
tended.
Correct mounting location
The module must not be mounted as overhead glazing, e.g.
on a facade. In addition to the module itself, the mounting
system must also be able to easily withstand the expected
load from the conditions at the installation site (snowfall,
wind).
The underside of the module frame is provided with pe-
nings that allow precipitation water to run off. During in-
stallation, make sure these openings are not restricted in
their function.
If used in an upright installation, the socket can be moun-
ted pointing upwards and downwards. Otherwise only ins-
tallation with the junction box facing upwards is permitted.
Assuring yield through optimum alignment and
inclination
We recommend planning the suitable orientation and cor-
rect tilt angle of the modules before installation, so that
the system can achieve optimum yield performance. Ideal
conditions for power generation prevail when the sun‘s rays
hit the generator surface perpendicularly.
To avoid any loss of performance when connected in se-
ries, please make sure that all modules are installed with
the same orientation and inclination.
Installing the module free from shade
Even slight shading reduces the yield from the system.
It is therefore particularly important to install the modu-
le as free of shading as possible. There should be no full
shading throughout the year, and unhindered exposure to
sunlight should be ensured for several hours, even on days
when the calendar is unfavourable.

Ensuring sucient rear ventilation
ucient rear ventilation ensures that performance-redu-
cing heat accumulation can be avoided.
Secure mounting
In order to mount the modules as intended, they must each
be securely fastened by at least four points. Framed PV
modules may be clamped on the short and on the long si-
des.
NOTE: Ensure that the maximum mechanical load capacity
of the modules is observed, taking into account the wind
and snow load zones as well as the terrain category and
building height.
Instructions for installation
The modules can be connected to the substructurein vari-
ous ways: either by clamping the modules from the front
(see example 1) or by screwing the modules into the moun-
ting holes provided from behind (see example 2).
Use a torque wrench during installation. In the examples
shown, the tightening torque to be applied is between 16-
20 Nm. Please note that 20 Nm must not be exceeded.
M8 screws made of V2A must be used. Only use the exis-
ting drill holes for installation. The drilling of further holes
would lead to a loss of warranty.
Loads
Depending on the type of mounting, the solar modules are
able to withstand the respective load. In principle, make
sure that the solar modules are not subject to unnecessary
stress.
When using the clamp-on mounting method (see example
1), the xing points in extended clamping areas must be ta-
ken into account. A graphic representation of the clamping
areas can be found on page 10.
Please note that failure to comply will void any claim
on corresponding warranty services.

Proper cabling
Under no circumstances open the junction box. The mo-
dules are already equipped ex works with the necessary
cables and connectors.
Ensuring correct wiring
The integrated connecting cables are UV-resistant. The
connecting cables have a conductor cross-section of 4
mm².
For connection, the connecting cables have pre-assembled
connectors that are protected against reverse polarity. En-
sure that the total area of all conductor loops is kept as
small as possible to reduce voltages caused by indirect
lightning strikes. It is essential to subject the wiring to a
thorough nal check before the generator is put into opera-
tion. If the measured open-circuit voltage deviates from the
specication, there is a connection error. Also make sure
the polarity is correct.
Insert the plug connectors correctly. Connectors may only
be inserted in a dry condition. Also make sure that gap-free
connection is possible. In addition, the requirements of the
inverters that are used must be observed.
The modules are connected in parallel, appropriate over-
current protection must be used. Fuses for DC voltage
must be used for this purpose, which prevent a reverse cur-
rent greater than 15 A.
Also observe the connection conditions and the design gui-
delines of the inverter manufacturers.
Check the plug-in connection of the supplied modules be-
fore installation and if the completed strings are working
correctly after completion of each string. This is performed
by means of a voltage test. Explicit attention must be paid
here to the snap-in between the plastic cable sheath and
the aluminium cable sheath. The snap-in should be audible.
If the string and/or the plug-in connection does not appear
to work correctly, contact Solar Fabrik GmbH immediately.
Using suitable materials only
The system may only be wired with special solar cables in
accordance with DIN EN 50618 class 5
and suitable plugs.
It is of utmost importance that all materials used are in
perfect electrical and mechanical condition. Only use sing-
le-core cables and select the appropriate conductor cross-
section to minimise the voltage drop.
Only use suitable cables with a minimum cross section of 4
mm² for the further connection of the modules. For longer
distances, the cable cross section must be adjusted accor-
dingly. For cable laying, also follow the specied require-
ments in accordance with DIN VDE 0298-3.

Protecting the cables from damaging
environmental inuences
Only use UV-resistant cable ties to x the cables to the
mounting system. Protect exposed cables from possible
damage, e.g. by laying them in plastic pipes. Avoid direct
sunlight.
Under normal conditions, a PV module can deliver a higher
current and/or voltage than specied in the standardised
test conditions under expected conditions. To determine
the rated voltage values of components, rated current va-
lues of conductors, sizes of fuses and dimensioning of
controllers connected to the output of PV modules.
The values of Isc and Uoc edges. Furthermore, avoid soi-
ling indicated on the module should therefore be multiplied
by a factor of 1.25.
Ensuring the plug connectors are
correctly installed
To ensure that connectors are used correctly, it is permitted
to disconnect the module cable shortly before the module
connector and to install an alternative connector approved
in writing by Solar Fabrik GmbH .
The connectors marketed by Solar Fabrik GmbH are ap-
proved for mounting. Further informations are available
on request. Please contact your Solar Fabrik GmbH sales
representative.
The mounting of the connector on the module must be car-
ried out according to the mounting instructions enclosed
with the connector. The complete reassembly of the plug
connector may only be carried out at ground level. It is also
important to ensure that the module is not connected to
the generator eld during operation.
The photoactive front side of the module should be cove-
red as far as possible or face the ground during all work
steps to keep the voltage low. If all installation instructions
are observed and the installation is carried out by a tech-
nical specialist, the product guarantee of the modules re-
mains in full force.
Maintenance and cleaning
Usually rainfall ensures that the modules are cleaned au-
tomatically. With sucient inclination (greater than 15°),
it is therefore generally not necessary to specially clean
the modules. In the event of heavy soiling, we recommend
cleaning with plenty of water, but without cleaning agents.
Wear clean, non-slip gloves during all transport and instal-
lation work to prevent injury from cuts on module edges.
Furthermore, avoid soiling the solar glass with ngerprints,
as they can damage the special coating of the glass.
In case of heavy soiling, we recommend cleaning with
plenty of water with low levels of lime. The pH value of
the water should be between 6.0 and 7.5. Please do not
use any nozzle attachment and only an appropriate water
pressure and temperature. The use of cleaning agents and
scratching cleaning equipment would damage the special
anti-reective coating and invalidate the product and per-
formance guarantee.
Never scrape off or rub off impurities when the module is
dry. Damage to the highly ecient antireective surface
can lead to optical changes of the module surface as well
as to power losses.
The use of automatic cleaning machines for solar systems
is at your own risk and is not approved by Solar Fabrik
GmbH.
Inspect the system regularly and checkthe system for:
+Secure attachment and that all fastenings are free of
corrosion
+Safe connection, cleanliness, integrity and that all
cable connections are freed from corrosion
+ Contact resistances of the potential equalisation
