6 Handling aleo modules
6.1 Intended use
6.1.1 Appropriate use
aleo modules are used for generating electrical power in
stationary, photovoltaic systems which are connected to
the grid. If you would like to use the modules for another
purpose, such as for charging an accumulator directly, you
may need additional components (e.g. string diodes).
aleo modules are suitable for installing near livestock farms
and coastal regions.
Observe all the applicable legislation, regulations, guidelines
and standards when installing and operating the modules.
6.1.2 Inappropriate use
NOTE
• Do not install aleo modules on vehicles and do not
use them in air, space or seafaring applications and
also not 2000m above sea level.
• Do not use aleo modules if they are exposed to con-
centrated sunlight or strong artificial light, or if they
could be immersed in water or other liquids or expo-
sed to vapour.
6.1.3 Product-specific information
Product-specific information (e.g. the data sheet) contains
details of a particular type of module.
Only use aleo modules for the intended purpose outlined in
the product-specific information.

Quick Reference Manual Rel. 4.7, 08/2020, EN Page 5/20
Severe or fatal injuries from electric shock!
• If the circuit of your photovoltaic generator is
earthed, remove the earth before you carry out
electrical work on the generator.
_________________________________________________________________________
WARNING!
Contact with live parts due to unsuitable tools
or weather conditions. Risk of electric shock!
• Only use approved, insulated tools for maintenance
work on live parts.
• Work in dry conditions. Ensure that the electrical
connections of the solar module, the cables and the
tools, are dry.
_________________________________________________________________________
RECOMMENDATION
Work in pairs so that in an emergency one person is
able to help in the case of injury. This is because the
modules generate voltage as soon as they are expo-
sed to light. Therefore, parts of the system are
nearly always energised during the daytime.
6.2.2 Mechanical safety precautions
WARNING!
Glass can crack, break or splinter. Beware of
injury!
• Never step or sit on solar modules.
• Avoid knocking and bumping the surface,
the edges and corners of the glass panels.
________________________________________ _________________________________
WARNING!
Exposed live parts due to damaged glass. Risk of
electric shock!
• Only use modules with the insulation in perfect
condition.
________________________________________ _________________________________
CAUTION!
Sharp glass edges or flying glass splinters.
Beware of injury!
• Always use suitable protective equipment (e.g.
gloves and goggles).
• Be especially careful with the glass edges and
corners of laminates (frameless modules).
________________________________________ _________________________________
■ Insulating back sheet
WARNING!
Damaged insulating back sheet. Risk of electric
shock and burns!
• Avoid any contact with the back of the module with
sharp or pointed objects.
• Ensure that the back sheet remains undamaged.
_______________________________________________
This module is rated for use in application class A accor-
ding to iEC 61730. For the electrical data please refer to
the data sheet or the name plate.
Under normal conditions, solar modules are likely to
experience conditions that produce more current and/or
voltage than reported at standard test conditions.1
Accordingly, the values of ISC and VOC marked on the mo-
dules should be multiplied by a faktor of 1.25 when deter-
mining component voltage ratings, conductor ampacities,
fuse sizes, and size of controls connected to the PV output.
Data sheets may change without prior notice. If the infor-
mation in the data sheet differs from this manual, the data
sheet takes precedence

7 Preparing for installation
7.1 Handling aleo modules
7.1.1 Storing modules
■ Framed modules
Modules in packaging units:
NOTE
• Store the aleo modules upright in the packaging
units. Make sure that each module has sufficient
support.
• Do not stack the packaging units. This could damage
the modules.
• Store the modules in dry conditions. Packaging is
not waterproof.
• Store the modules at an ambient temperature of
max. 40°C.
Individual modules:
NOTE
• Store individual aleo modules in an upright position
on wedges with suitable padding. Use adequate pad
ding between the individual modules.
• Avoid stacking individual modules, as well as the
pallets they rest on.
• Store the modules in dry conditions.
• Store the modules at an ambient temperature of
max. 40°C
7.1.2 Unpacking modules
■ Framed modules
NOTE
• Using an underlay, incline the pallet (e.g. with a
beam, height approx. 10 cm for 5° inclination), so
that the opening on the front of the box is elevated.
The modules then lean back in the box which makes
it easier to remove them.
• Use an underlay for inclining which supports the
whole side of the pallet (e.g. a beam). This keeps
the modules supported in the box along their entire
width.
• Remove the module from this side only. Remove the
module with the help of another person, if possible.
• Observe the unpacking instructions on the module
box.
7.1.3 Checking modules
NOTE
• Before installation, check each aleo module forme-
chanical defects. Pay particular attention to possible
damage to glass panels and insulated back sheets.
• In addition, check the insulation on the cables,
connectors and junction boxes.
• If you discover any defects, report them to the
supplier or transport company immediately.
7.1.4 Transporting modules to the installation site
■ Framed modules
NOTE
• Always carry the aleo module with one other per
son. Take hold of the module on its long sides.
• When transporting individual modules, make sure
that you do not put any strain or pressure on the
junction box and cables.
7.2 Safety precautions
DANGER!
When installing on roofs or other elevated sites,
objects may fall down.
Severe or fatal injuries are possible!
• Block off the danger zone for people and animals
before beginning installation work. If possible,
remove all objects from the danger zone.
_______________________________________________
DANGER!
Electric arcs form when electrical connections
are made or disconnected incorrectly.
Severe or fatal injuries from electric shock or
severe injury from burns!
• Disconnect the photovoltaic generator before you
carry out any work on the electrical components of
the photovoltaic generator.
_______________________________________________
DANGER!
High DC voltages, even when the photovoltaic
generator is disconnected, if the generator is
earthed.
Severe or fatal injuries from electric shock!
• If the circuit of your photovoltaic generator is
earthed, remove the earth before carrying out
electrical work on the generator.
_______________________________________________
WARNING!
Exposed live parts on damaged modules.
Danger of electric shock!
• Only use components which are in perfect condition
for use in photovoltaic systems. Do not install solar
modules with visible damage to the glass panels,
the insulating back sheet or on the insulation of
electrical connections.

8 Mechanical Installation
8.1 Mounting orientation for modules
8.1.1 Vertical (portrait) mounting
When mounting the module vertically, make sure that the
cables are facing towards the ground and the junction box
is facing upwards.
8.1.2 Horizontal (landscape) mounting
When mounting horizontally, make sure that the exit holes
for the cables on the module or the junction box are positi-
oned on the inside of the photovoltaic generator. Avoid the
lateral outer edges of the photovoltaic generator to minimi-
se the effect of ambient conditions, such as wind or rain.
8.1.3 Inclination
Incline the surface of the modules at an angle of at least
10° horizontally, so that precipitation can drain off which
supports the modules self-cleaning.
For optimum self-cleaning, we recommend an angle of at
least 15° horizontally.
Fig.1 Recommended position of the junction boxes for
horizontal mounting (facing the middle of the
generator)
8.2 Safety precautions
NOTE
• Do not drill any additional holes in aleo modules
or their frames.
8.3 Improper mounting
NOTE
• Do not attach the modules using nails. The
vibration created in the process can cause micro
fissures and loss of yield, and results in loss of
warranty rights.
• Do not attach the modules by welding. The
temperatures created in the process can cause
delamination, micro fissures and loss of yield, and
results in loss of warranty rights.
8.4 Intervals
8.4.1 Intervals between modules with standard frames
NOTE
• Leave a minimum clearance when mounting
modules. This prevents mechanical tension due to
thermal expansion.
• When mounting at intervals
Leave a clearance of 3 mm or more between the
individual module frames.
• For edge-to-edge mounting
Allow for an expansion joint of 20 mm aer a
maximum of 7 m.
• The recommended maximum clearance is 30 cm,
based on the modules‘ standard cable length.
aleo solar recommends mounting at intervals. Also note
the information from the mounting equipment vendor.
This could specify larger intervals.

Page 8/20
8.4.2 Clearance under the modules
■ Minimum clearance
NOTE
• Rooop or freefield mounting
Ensure a clearance of at least 4 cm between the rear
edge of the frame and the mounting surface (e.g.
the roof tiles) for the rear ventilation ohe aleo
module.
• Roof-integrated mounting
Ensure an appropriate interval, for example, to the
trough of the mounting system. Also ensure ade-
quate ridge ventilation, for example, with a roof
ridge ventilator.
■ Maximum clearance
NOTE
• The largest permissible clearance is defined by
national standards. This is used to design the instal
lation on the assumed effects of wind and suction.
• The actual maximum clearance of an installation is
determined by the sub-structure. Ensure that your
sub-structure adheres to the permissible
clearances.
8.5 Avoiding seals
NOTE
• Avoid the use of a seal between aleo modules and
their mounting surface.
• Dry and cool operation can have a positive effect
on the performance as well as the service life of an
aleo module.
• Also for roof-integrated mounting, ensure good
rear ventilation to minimise loss of output which
results from a higher module temperature. Ensure
adequate ridge ventilation, for example, with a
roof ridge ventilator.
8.6 Clearance under the modules
NOTE
• Keep the space behind the laminate free of any
objects. This prevents damage to the insulating
back sheet and the junction box.
• Ensure that sharp or conductive parts (e.g. screws
or nails) do not protrude into the space behind the
module.
• If possible, take measures to prevent foreign
objects (e.g. snow, ice, leaves, twigs, branches
from being able to get behind the module.
8.7 Shadowing
8.7.1 Avoidance of shadowing
NOTE
• Avoid shadowing of solar modules. This applies also
and especially for shadowing of small areas due to close
small objects like antennas or lightning protectors.
• If there is systematical shadowing in the course of the
day or year because of adjacent objects at the site and
you do not have any opportunity to affect the shado-
wing, then:
- take another site into consideration
- only plan with the non-shadowed parts of your site
when you configure your photovoltaic-generator
8.7.2 Effects of shadowing
NOTE
Even shadowing of a single module or solar cell can
appreciably affect the power output of your photovoltaic
plant.
If shadow falls on single solar modules of a photovoltaic
generator or on single solar cells of a solar module, the
shadowed parts generate less or no electrical power
anymore. This may affect the yield of the whole module
string and therefore the whole generator.
Furthermore, shadowing oen causes the solar cells to
consume the otherwise in the module generated electri-
cal power. This may cause warming of the shadowed cells
in comparison to the not shaded cells, which in extreme
cases can raise the risk of fire.
Constant or systematic shadowing can cause a serious
yield loss and may accelerate the aging process and
therefore causes power loss or failures of the photovol-
taic generator. Avoid shadowing e.g. caused by building
parts, depending on day time or season (esp. in winter) to
optimize the yield and durability of your plant.
8.7.3 Protective devices of the modules
Aleo modules are equipped with bypass-elements to limit
the temperature rising because of the internal power con-
sumption induced by shadowing to a non-critical grade and
thus protect the module. Avoid systematic shadowing also
because the bypass-elements are not suited for constant,
long lasting loads.

• PV-JM601 connectors
• Only plug PV-JM601 connectors into PV-JM601
connectors.
9.1.3 Replacing the connectors
You can remove the connector on a module and replace
it with another connector, which is released by aleo (see
Chapter 9.1.2) if necessary. You retain the manufactu-
ring warranty if you remove and mount with approved
tools in the proper way and according to the connector
manufacturer‘s instructions.
9.2 Laying the string cables
CAUTION!
Brittle fractures in junction boxes due to contact
with unsuitable connection cables: Risk of fire!
• Only use connection cables without plasticisers.
______________________________________________
2The original Multicontact® MC4 connectors are referred to as “MC4” in the data sheet.
NOTE
NOTE
• Avoid any tensile and pressure loads on the
junction box when mounting.
• When mounting, avoid heavy tensile loads on any
connectors already plugged in.
NOTE
• Bend the cables from the connector at least 4 cm
aer they exit from the connector.
• Bend the cables from the junction box as well, at
least 4 cm aer they exit from the connector.
• This keeps the cables waterproof at the cable
outlet.
Observe the guidelines on laying the respective cables.
Lay all cables ensuring that:
• You adhere to the minimum bend radius (e.g.
5-fold cable diameter).
• You avoid laying near sharp corners and edges or
protect the cables accordingly.
• cables must not lay between module backside and
mounting system parts.
• You protect them from direct sunlight and
precipitation.
• You secure the cables with UV resistant cable clips4
or other suitable cable fasteners which protect the
cable insulation.
• Cables from module strings are laid as near to
each other as possible to minimise the effects of
being struck by lightning.
9.2.1 Weather protection
NOTE
• Lay the cables so that they exit the junction box
from below. This prevents water, which runs along
the cable, from collecting at the point where the
cables exit the junction box.
• For modules mounted horizontally, lay the cables
in a U-form away from the junction box.
• Modules mounted vertically do not usually need
any additional adjustments.
Fig.2 U-form cables at the junction box for a horizontally
mounted module
3Some countries specify a larger bend radius, e.g. 8-fold wire diameter in the USA (NEC
Codebook 2011).
4For attaching the cable clip, use a suitable tool which can fully tighten at a defined
low force. Avoid cable clips and tools which constrict or damage the cable insulation
when tightening.

Lay cables carefully to protect against damage from:
• Direct environmental factors, such as precipitation
• movement (e.g. from wind)
• Indirect environmental factors, e.g. snow or ice,
which slip down behind the modules, and
• Chaffing on the insulation due to the cable moving
(e.g. from wind or ice).
9.3 Potential equalisation (earthing) of module
frames
NOTE
• Local regulations may specify potential equalisation
(earthing).
• When earthing the module frame, establish a safe
electrical connection to the earth potential or
earthed sub-structure.
• Observe the requirements and recommendations
of the inverter manufacturer, as well as insurance
policies.
• The module frames are made of aluminium. When
mounting onto other materials, take suitable mea-
sures to prevent electric corrosion, e.g. by using a
coating.
NOTE
Potential equalization does not serve as lightning
protection. Lightning protection may be necessary
in addition to potential equalization.
2Some countries specify a larger bend radius, e.g. 8-fold wire diameter in the
USA (NEC Codebook 2011).
3For attaching the cable clip, use a suitable tool which can fully tighten at a de-
fined low force. Avoid cable clips and tools which constrict or damage the cable
insulation when tightening.

9.5 Parallel and serial connection
PV modules of the same type can be connected in parallel.
The PV modules in this series are fundamentally designed
for series connection.
• Only use PV modules of the same type and output
for parallel connection. Take measures for over-
current protection (e.g. line fuses) if necessary. Never
exceed the specified reverse current loadability of
the PV modules. Maximum number of module strings
that are allowed to be switched in parallel: 2 (fuse
rating / (short-circuit current x1.25)+1)
• Make sure that only PV modules with the same
amperage (Impp) are interconnected for series con-
nection and make sure that the voltages of strings
connected in parallel are the same. Even at low tem-
peratures, never exceed the maximum permissible
system voltage of the PV modules. Maximum number
of PV modules that are allowed to be switched in
series: maximum system voltage / (open circuit
voltage x 1.25), with respect to the temperature
coefficient.
• Make sure that the number and connection of the
PV modules match the electrical values specified by
the devices connected to the photovoltaic system.
• Make sure that the polarity is correct.

10.2 Clamp mounting for modules with standard
frames
Lay cables carefully to protect against damage from:
• Direct environmental factors, such as precipitation
• movement (e.g. from wind)
• Indirect environmental factors, e.g. snow or ice,
which slip down behind the modules, and
• Chaffing on the insulation due to the cable
moving (e.g. from wind or ice).

frames
NOTE
• Local regulations may specify potential
equalisation (earthing).
• When earthing the module frame, establish a safe
electrical connection to the earth potential or

9.4 Lightning protection
WARNING!
Absence of or inadequate lightning protection.
Risk of fire or electric shock!
• Leave the planning and installation of the external,
and if required internal, lightning protection to be
carried out by qualified technicians at all times.
• It is essential to integrate an arrestor for
connecting the lightning rod with the lightning
protection. This ensures the safety and reliability
of the lightning protection as well as the
photovoltaic system.
• Do not under any circumstances include the
module frame or its earth as an active part of the
lightning protection (e.g. as a lightning arrestor).
_______________________________________________
NOTE
If you earth the module frame, the only task of this
earth is the potential equalisation between the
module frame and the supporting structure.
