1. Introduction
2. Local conditions and site survey
We are pleased that you have decided on AxSun
Solar modules for your PV-system. In order to
maintain our high quality modules in good
condition for many years, it is necessary to have
them installed and maintained by skilled
personnel. Read this instruction manual in its
entirety and keep this manual in a safe place.
AxSun Solar modules are proofed for use in
moderate climatic conditions (IEC 61215).
Operation temperature is from -40 °C to +85 °C. In
order to avoid loss of power, all modules
connected in series, should be installed in an allseason shadow-free area. Even partial shadowing
results in losses of yield and should be avoided.
Ventilation of the modules’ back side will prevent
heat build-up which affects the energy yield.
This instruction manual is addressed to installers
and plant operators who are in charge of
installation, commissioning and operating of AxSun
Solar modules. It contains useful information to
keep the photovoltaic system at its optimum over
its entire lifespan.
During installation work, follow all local laws and
regulations regarding fire protection (see also
paragraph 2.2 regulations and standards). The
installation of a PV system may affect the fire
safety of a building. Faulty installation may lead to
fire hazard. For this reason, AxSun Solar modules
shall be installed on suitable and fire resistant
roofings, only. In case of fire, the fire fighters must
have access to the PV system.
The purpose of the following instruction is to help
you to properly install the Axsun Solar modules. In
certain cases please ask for expert advice to
accommodate the local conditions. All applicable
international, national, and local regulations,
standards and requirements shall be followed.
Generally, it is recommended to insure for your PVsystem.
Solar modules are no explosion-protected
equipment. Modules must not be installed in the
vicinity of highly flammable gases, vapors or dusts
(e.g. gas tanks, filling stations, paint spraying
equipment). Modules must not be installed next to
open flames and highly inflammable material.
1.1. Intended use
AxSun Solar modules may only be used according
to their suitability. The use for any other purpose is
not allowed. The modules may not be technically
altered. Failure to comply with this instruction
manual will invalidate the module warranty.
The modules mentioned in this instruction manual
must not be used on vehicles of any kind and are
not suitable for building integration and overhead
glazing. Artificially concentrated sunlight shall not
be directed on the modules.
1.2. Safety information
AxSun Solar modules shall only be installed by
qualified professionals. Keep children and animals
away from the installation site. Inform people who
are in the building about your work. Follow local
and national regulations for photovoltaic systems
(see also paragraph 2.2 regulations and standards).
Failure to comply with the regulations can lead to
personal injuries and material damages. This
instruction manual is based on German law and
regulations.
Make sure that the modules will never be
submerged in water or be exposed to continuous
wetting (e.g. by fountains). Installation under
water or close to fountains is not allowed.
Exposure to salt or sulfur (sulfur sources,
volcanoes) implies a risk of corrosion. A distance of
500 meters to an ocean shall be kept. AxSun Solar
modules should not be affected by chemical
emissions (e.g. chemical industries).
1.3. Malfunction
2.1. Orientation and pitch
In case of a malfunction please call your local
installer. Do not try to repair the system by
yourself.
In order to avoid yield losses, all modules
connected in series should be arranged with the
same orientation and pitch. The best orientation
depends on the latitude. We recommend the use
of suitable software tools.

Solar modules generate direct current (DC). When
disconnecting an electric circuit carrying direct
current, electric arcs can occur that may result in
life-threatening injuries. Direct current electric arcs
are not self-extinguishing. This may result in mortal
burn and fire hazard. They can destroy connectors
and contact parts. Please observe the following:
 Remove or open the AC circuit breaker of the
inverter before you disconnect the inverter
from the grid.
 Never isolate the solar generator from the
inverter as long as the inverter is still
connected to the grid.

AxSun Solar modules are suitable for wind and
snow loads up to 5400 Pa when installed properly
according to this instruction manual.
 Clamps
must
fulfil
the
structural
requirements of the installation site.
4.5. Mounting structure requirements
 Use of long-term stable clamps that securely
fix the modules to the mounting structure.
Mounting frames and clamps must be compatible.
Requirements for the mounting structure are:
4.7. Selection of the modules
 Comply with local snow and wind loads.
Only connect modules of the same type and the
same power class to achieve optimal yield.
 Properly fastened to the ground, the roof or
façade.
4.8. Safety factor
 Forces acting on the modules are transferred
into the mounting substructure.
 Ensure that no mechanical stresses are
generated on the module (e.g. caused by
vibrations, twisting, or expansion).
During normal operation, it may occur that the
module provides a higher current and/or a higher
voltage than that determined under standard test
conditions. Therefore, please calculate a safety
factor of 1.25 when
 Ensure sufficient rear ventilation of the
modules.
 Determining the voltage design value (VOC) of
the components
 Allows for stress free expansion and
contraction due to temperature fluctuations.
 Determining the current design values of the
conductors (ISC) and
 Ensure long-term stability.
 Determining the ratings of the control units
connected to the solar module output.
 Ensure that no contact corrosion between
different metals occur due to its
electrochemical series.
Please always refer to local requirements and
regulations for the installation of electrical
systems.
4.6. Module installation
4.9. Series connection

This ensures that the maximum system voltage,
including all necessary safety margins, is not
exceeded.
4.12. Earthing
Warning!
During the planning phase of the PV system bear in
mind the voltage limit of the inverter when
determining the string size.
Wrong or faulty earhing increases fire hazard.
4.10. Parallel connection
The connected modules must be of the same
power class and type. The maximum reverse
current rating, indicated on the data sheet, has to
be observed. Modules may be damaged by the
occurrence of reverse currents due to module
defects, ground leak or defective insulation.
4.12.1. Functional earthing
Functional earthing is absolutely essential when
the installation of the system is < 500 m from the
sea.
Ensure that no hazard to life or physical condition
occurs when direct earthing. Observe all
regulations regarding fire protection and personal
security. (see paragraph 2.2.).
In order to install a safe functional earthing please:
In order to limit reverse currents that may occur,
we recommend using the following safety options:
 Version 1: Layout with a limited number of
parallel
connected
strings.
Without
undertaking further string overcurrent
protection, a maximum of three module
strings may be operated in parallel on an
inverter or MPP tracker.
 Only use inverters suitable for functional
earthing.
 Only earth the negative pole of the system.
 Only use earthing components that are
compatible with the inverter’s requirements.
 Version 2: Use of string diodes. When parallel
connection is planned the strings can be
protected against reverse current from the
remaining parts of the system by using a
corporate string diode. A maximum of three
strings may use one corporate diode if three
or more strings are supposed to be
connected in parallel.
 Observe the earthing instructions given by
the inverter manufacturer.
 Version 3: Layout with overcurrent
protection devices. Install overcurrent
protection devices in the positive and
negative conductors of each string. Observe
the
overcurrent

Meet and observe all local regulations and
standards. Fix the protective earthing (according
to the drawing) with a Parker screw to the earthing
points. The earthing points are labelled with this
symbol:
 Never open the junction box. Do not remove
bypass diodes.
4.13.2. Cables and plug connectors
When chosing and using cables and plug
connectors please observe the following:
Use Parker screws according to DIN 7981, Material
A2, Size 5.5 mm x 16 mm.
Use specified solar cables only. Use the same
connector systems and connector systems
compatible with the inverter within one solar
system.
Ensure that all electrical components are in a
proper, dry and safe condition. Thus, you can avoid
short circuits or hazardous touch voltage, caused
by faulty or damaged cables.
Ensure that the cabling is not under mechanical
stress.
Ensure for a tight connection of each of the plugs
(in particular to the inverter). Observe that the
plugs click together audibly.
4.13. Electrical installation
Electrical work may only be performed by
accredited and licensed electricians.
4.13.1. Safety regulations
 Disconnecting a DC circuit may cause electric
arcs which can lead to life-threatening
injuries.
 Never disconnect plugs under load.
 Ensure that the modules are disconnected at
the inverter prior to separation.
 Make sure to observe the specified time
intervals after switching off the inverter and
before starting further works. High-voltage

5. Handling of the modules
6. Maintenance
For completeness and visual lack of damage
inspect your consignment directly after delivery.
Any damages must be mentioned in writing on the
lorry driver’s waybill AND to AxSun Solar. Inform
your dealer of any damages immediately.
AxSun Solar modules have been built for extreme
longevity and need only little maintenance and
cleaning. Dirt and grime are usually washed away
by rain if the modules have been installed with
appropriate pitch. If the modules are strongly
contaminated by dirt (e.g. foliage, bird droppings,
moss, soot etc.) and the rain is not efficient
enough, additional cleaning may be necessary.
Usually, snow slides off the modules,
automatically.
Handle the modules with care. Copy the serial
numbers of the modules before installation and file
them together with your documentation. Follow
any safety instructions on the packaging and
observe transport and storage instructions to avoid
any damage of the modules. Always keep the
electrical contacts dry and clean. Never
disassemble the solar modules. Never open the
junction box. Do not remove parts, symbols or type
labels which have been fixed by the manufacturer.
6.1. Cleaning
Clean AxSun Solar modules only when module
temperature is between 10°C and 30°C e.g. early in
the morning or late in the evening. Water
temperature should not exceed 40°C. Do not clean
the modules when there is a chance of frost and do
not clean the modules when the temperature
difference between module and air and water is
too high. Use water which is deficient in lime or
even better water without any lime (e.g. rain
water). This will prevent lime spots on the
module’s surface. Do not use scrubby cleaning
tools or cleaning supplies and no tensides. Do not
scratch off dirt. Do not rub off dirt when the
modules are in dry condition. Use plenty of water
and a soft cloth or sponge. Remove dirt from the
mounting system. (foliage, bird’s nests, etc.).
Observe the growth of grass around groundmounted PV-systems and cut the grass in due time
to avoid shading. Beware of cables and stonechipping while mowing. Never step on the modules
and do not subject the modules to any mechanical
stress. While cleaning the modules please observe
the warnings according to paragraph 2.2
regulations and standards. Do not enter the
installation area alone and unsecured.
We
recommend entrusting a qualified contractor for
the cleaning work. Ask your local installer for
advice.
5.1. Transportation
AxSun Solar modules must be transported and
stored up-right. In order to avoid damages
modules and packaging units must not be stacked.
Assure that the modules do not tip over. It is
recommended that the modules are carried by two
persons. Never lift or move the module using the
connection cables or junction box. Lift or move the
module at the frame. Ensure that the modules do
not yield or bend under their own weight during
transportation. In order to avoid micro cracks the
modules must not be stepped on and must not be
subject to any mechanical stress. Do not drop the
modules.
5.2. Storage
Leave AxSun Solar modules up-right in their
original packaging until installation. Store the
modules securely in cool, dry and ventilated
rooms. The packaging is not weatherproof.
5.3. Back Sheet protection
Damaged back sheets may cause threat to life or
physical condition. Therefore, protect the rear side
of the modules from sharp objects, from colours
and from glues. The back sheet protects the AxSun
Solar module from weather conditions like
moisture and water and provides electrical
isolation. Damaged back sheets can cause
delamination e.g. correction of the defects needs
to be done exclusively by AxSun Solar.
6.2. Maintenance
Disconnect the photovoltaic modules from other
parts of the system by switching off the DC isolator
before starting maintenance work.
The system should be inspected by an installer
annually. Ask your local installer for a service
contract regarding the annual maintenance of your
PV-system. This way you make sure that your PVsystem will be serviced regularly. Your installer will
be able to fix damages or to prevent the system
- 8/12 -

Fax 07392/96 96 851
from damages to guarantee a reliable operation of
the system.
This manual does not constitute a warranty of
Axsun Solar GmbH & Co.KG. The scope of liability
covers the contractual agreements of the
framework or of assumed warranties of the
framework only. There is no liability beyond the
functionality and safety of the modules.
The installer should check that:
 The cables are in excellent condition. The
cables must be securely fastened with no
mechanical stress subjected to the cables.
Observe the instructions for all other system
components which may be part of the complete
PV-system. It may be necessary to carry out a
structural analysis for the entire project.
 The modules are securely fastened.
 The contact resistances must be in excellent
condition and securely fixed.
Text and figures of this manual correspond to the
current technical specifications at time of print.
AxSun Solar reserves the right to make changes to
the product, specifications or this manual without
prior notice.
 All mechanical connections must be clean
and undamaged, securely fixed and securely
connected.
 All system components must be free of

Damages and abnormalities must be fixed
immediately. In case that an AxSun Solar module
has to be repaired please absolutely contact AxSun
Solar. Never try to repair the solar modul by
yourself. Improper repair work may cause damages
which may lead to a breakdown of the electrical
insulation in some years. Insufficient insulation
may cause mortal danger. In order to avoid
secondary damages and performance loss any
damages should be reported and repaired
immediately.
Laupheim, June 2014

Amendment Solar Laminates

Following procedure is valid for all laminates of
the AX-P and AX-M series
 Never lift or move or draw the laminates
using the connection cables or junction box.
1. Introduction
 Observe the polarity of the laminates.
(reverse connection may destroy the bypass
diodes).
We are pleased that you have decided on AxSun
Solar laminates for your PV-system. In order to
maintain our high quality laminates in good
condition for many years, it is necessary to have
them installed and maintained by skilled
personnel. Read this instruction manual in its
entirety and keep this manual in a safe place.
 The laminates must not be installed in an
angle that allows water to run into the
junction box (screw connections). The
junction box must never be at the lower end
of the laminate.
The instruction manual for AxSun solar modules
(part 1-8) is the basis for the amendment for solar
laminates. All warning and safety and legal clauses
listed therein also apply to the solar laminates. This
amendment provides additional information about
installation.
 Do not fix AxSun Solar-laminates at intervals.
Use plane (large-scale) mounting systems.
 The laminates have to be put in the frames at
least at their long sides (four-sided support
surface).
 Laminates with width of more than 800 mm
need additional backing. Moreover, these
laminates need a four-sided support surface.
Install the backings parallelly to the long sides
of the laminates. Centralise the backings to
avoid deflection of the laminates. The
backing must not damage the back sheet. The
design of the backing must be absorbed and
large-scale in a way that potential wind and
snow loads cannot damage the laminates.
When determining the mounting system, your
installer takes a significant impact on the longevity
of the laminates. Improper installation may cause
damage to the AxSun solar laminates for which
AxSun Solar is not liable.
2. Intended use
AxSun Solar laminates may only be used according
to their suitability. The use for any other purpose is
not allowed. The laminates may not be technically
altered. Failure to comply with this instruction
manual and in particular to safety regulations will
invalidate the module warranty. This manual is for
the use of laminates to fit into roof-integrated PVsystems
 Do not use glues or adhesive tapes to fix the
laminates.
 Only use mechanical mounts and clamps to
install the laminates.
 The edges of the laminates must never be in
retained water. Make sure that water resp.
snow can drain off.
 Please note that the edges of the laminates
are
shock-sensitive
despite
the
implementation of high quality, tempered
glasses.
3. Installaton instructions
 The laminates may not be stepped on
 Avoid build-up of heat on the back side of the
laminates..
 Observe the manufacturer instructions of the
mounting system as well.
 The mounting system must be suitable for
the installation of AxSun Solar-Laminates. The
suitable mounting system must ensure that
no mechanical tensions of the body assembly
may be transferred into the laminates.
Mechanical tensions cause cracks and
deformations of the back sheet.
Particularly, observe the distance between
the laminates. It must not happen that the
laminates touch each other due to possible
extensions of the materials (min. 10mm
 AxSun Solar assumes no liability for electronic
damages caused by heat build-up due to
inadequate ventilation (heat accumulation
beneath the laminate).
Penetration of
moisture e.g. by diffused melting water, may
cause significant loss of power.

 Delamination of laminates may be caused by:
 Heat or heat build-up due to a nonconforming mounting system.
 Cracks in the back sheet due to
incorrect installation
 Retained water due to incorrect
installation
 Make sure that all laminates are always
properly installed.
