3 General information
the Module Data Sheet provided with this product. Determine local permits, installation and inspection requirements before installing module(s). If not otherwise
specified, it is recommended that the requirements of
the U.S. National Electric Code (NEC) be followed.
This photovoltaic module produces electricity when
exposed to the sunlight, even at low light levels or when
other sources illuminate the front face. The electrical
hazard from the voltage and current of a single module is
low. However, the voltage increases as modules are
connected in series and the available current increases
as the modules are connected in parallel. Thus, for a
module connected within a system, contact with electrically active parts of the module such as terminals can
result in lethal shock, sparks, and burns. The only way to
eliminate this hazard is to prevent exposure of the
module(s) to light.
Important Notice!
To avoid the hazard of electric shock and injury when
installing, wiring, operating and maintaining the PV modules

1 Introduction
This manual contains information regarding installation,
operation, maintenance and safety handling of Bosch
Solar Energy AG photovoltaic modules. Before installation
or using the PV modules, it is important to read this manual and understand the instructions carefully.
The installation of solar PV modules requires a great
degree of skill and DC voltage exceeds 100 V, it only be
performed by a qualified licensed professional, including,
without limitation, licensed contractors and licensed
electricians. The installer assumes the risk of all injury
that might occur during installation, including without
limitation, the risk of electric shock.
Important Notice!
For your safety and the safety of others, please read the
entire Installation, Operation and Maintenance Manual
carefully prior to installing, wiring, operating and performing maintenance of PV modules. Also, carefully read
Cover the entire front surface of the PV modules with
a dense, opaque material such as the cardboard box,
during installation and handling of the modules.
Do not expose Back sheet foil directly to sunlight
Work only under dry conditions, with dry modules
and tools.
Be sure to completely ground all modules.
Since sparks may occur, do not install the module
where flammable gases or vapors are present.
Module installation and operation should be per-
formed by qualified personnel only.
Children and unauthorized persons should not be
allowed near the installation of PV modules.
Use module for its intended function only.
Be sure that all other system components are compat-
ible, and they do not subject the module to mechanical or electrical hazards.
Do not touch terminals while module is exposed to
light or during installation.

Provide suitable guards to prevent contact with
30 VDC or greater. As a Precaution use properly insulated tools only.
Do not damage or scratch the back sheet of the
module.
Do not use the junction box to hold or transport the
module.
Do not drop module or allow objects to fall on mod-
ule.
Do not stand or step on the module.
Do not disassemble, modify or adapt the module or
remove any part or labeling installed by the manufacturer.
Do not drill holes in the frame or glass of the mod-
ule.
Do not treat back sheet and front surface of the
module with paint and adhesives.
Do not artificially concentrate light on the module.
Do not wear metallic jewelry while installing or
trouble shooting the module.
Do not change the wiring of bypass diodes.
Do not disconnect modules under load
To help avoid breakage problems
Always transport and store the module in the ship-
ping container provided.
When carrying a module two or more people should
carry it by its frame and wear non-slip gloves (to
avoid injury by a slipping module, to a foot, or cuts by
the edge of a frame, and so on).
Do not leave the module unsupported or unsecured
prior to installation. For example, wind can cause a
module which is leaning against a fence to fall and
break. Avoid application of excessive bending or
twisting forces to the module.
A module with broken glass or torn back-skin cannot
be repaired and must not be used since contact with
any module surface or the frame can produce electrical shock.
Broken or damaged modules must be handled care-
fully and disposed of properly.
Broken glass can be sharp and can cause injury if not
handled with the appropriate protective equipment.
4 Genaral safety
Follow all permission, installation and inspection requirements.
Before installing modules, contact the appropriate
authorities to determine permissions, installation,
and inspection requirements which should be followed.
Electrically ground modules for all systems of any
voltage.
If not otherwise specified, it is recommended that
requirements of the latest National Electrical Code
(USA) or other national or international electrical
standards be used.
Be sure that the construction or structure (roof,
facade, etc.) where the modules are being installed
has enough strength. For modules mounted on roofs,
special construction or structures may be required to
help provide proper installation. Both roof construction and module installation design have an effect on
the fire resistance of a building. Improper installation
may contribute to fire hazards. Additional devices
such as ground fault, fuses, and disconnects may be
required.
Do not use modules of different specifications in the
same system.
Follow all safety precautions of other system compo-
nents used.
To satisfy regulatory requirements, when installing the
modules, be sure to:
1. Use only stranded or solid copper single-conductor
type UF cable or USE cable rated sunlight resistant,
for modules and modules interconnect wiring that is
exposed to weather.
2. Observe the requirements described in sections
labeled INSTALLATION and SPECIFICATIONS of this
manual.
3. Grounding of the module frame is required. When
2
ground wires greater than 6 mm
required, the installer will need to provide suitable
terminal connectors.
(No.10 AWG) are
4. Under normal conditions, a photovoltaic module is
likely to experience conditions that produce more
current 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 1.25 when determining component voltage
ratings, conductor capacities, fuse sizes, and size of
controls connected to the PV output.
5. Refer to section 690-8 of the National Electric Code
(NEC) for an additional multiplying factor of 125 %
(80 % de-rating) which may be applicable.
6. Conductor recommendations: single conductor cable,
type USE-2 12 AWG, rated 600 V/1000 V minimum,
90° C minimum, marked sunlight resistant.
5 Installation
Important Notice!
General
Please read this guide completely before installation
or use of the modules. This section contains electrical and mechanical specifications needed before
using your Bosch Solar Energy AG PV modules.
Modules should be firmly fixed in place in a manner
suitable to withstand all expected loads, including
wind and snow loads. Module mounting holes are
provided for easy installation and proper mechanical
loading.
Modules should be mounted with the orientation and
tilt angle required for consistent performance (sea-
sonally, yearly). The location should be selected to
have direct access to sunlight from 9:00a.m. to
3.00p.m. on the shortest day of the year. Calculate
the tilt angle by using the site latitude plus 20 degrees, with modules facing south in the northern
latitudes and north in the southern latitudes. This
will result in consistent energy output throughout the
year.
The appropriate material should be used for mount-
ing hardware to prevent the module frame, mounting
structure, and hardware itself from corrosion.
Install modules where they are not shaded by obsta-
cles like buildings and trees.
Especially pay attention to avoid partially shading the
modules by objects during the daytime.
For roof mounted systems, provide adequate rear
ventilation under a module for cooling (100 mm: 4in
gap minimum)
Clearance of 7mm: 0.25” or more between modules
is required to allow for thermal expansion of the
frames.
Observe the specifications for mounting areas ac-
cording to Illustrations 1 and 2.
Attachment with clamps on the narrow sides of the
solar module may not be performed.
The attachment of the solar module can be per-
formed with clamps (or as an alternative, directly on
the installation holes). When clamping systems are
used, the clamp surface per attachment point on the
module must amount to at least 400 mm².
Position of the installation drill holes in accordance
with Illustrations 3
Please contact your Bosch Solar Energy AG authorized
representative with questions regarding
mounting profiles for modules.

Notes on Installation
Clearance between the module frame and the mount-
ing surface is required to allow cooling air to circulate around the back of the module. This also allows
any condensation or moisture to dissipate. The module should never be sealed to the mounting surface
with sealant that prevents air from circulating under
the module.
Leave 4 inches of clearance between the roof and the
module frame.
Refer to your local authority for guidelines and re-
quirements for building or structural fire safety.
For roof application, the modules should be mounted
over a fire resistant covering rated for the application
Standard Operating Condition
Bosch Solar Energy AG recommends that modules be
operated under Standard Operating Conditions (SOC).
An installation location with conditions exceeding SOC
or with other Special Conditions (see below) should be
avoided. SOC of Bosch Solar Energy AG modules is as
follows:
1. Standard Operating Conditions (SOC)
The modules should be operated only in terrestrial
applications. No space or other Special Conditions
(see below).
The measured ambient temperature of the installa-
tion location should be within –20º C (-4° F) to 40º C
(104° F).
The lower and upper temperature limit is defined as
the monthly average low or high of the installation
location.
The relative humidity should be within 45 % to 95 %.
The installation place should be less than 1,000 m
(3,280ft) above sea level.
Installations more than 1,000 m (3,280 ft) are allowed
only if the wind pressure load for a module is less
2
than 2,400N/m
(50PSF).
2. Special Conditions
The ambient temperature of the installation place
exceeds SOC.
The salt damage is heavy at the installation place.
The hail and snow damage is heavy at the installation
place.

Note: Modules in parallel can be done as applicable
General
All wiring should be done in accordance with applicable
electrical codes.
All wiring should be done by a qualified, licensed
professional. Wiring should be protected to help
ensure personal safety and to prevent its damage.
All Bosch Solar Energy AG modules are equipped
with wires and quick connectors. Modules have been
designed to be easily interconnected in series.
Modules can be wired in series to increase voltage.
Connect wires from positive terminal of one module
to the negative terminal of the next module. All mod-
ules connected in series should be of the same
model number and/or type. Make sure the number of
modules connected in series does not exceed: ((Max-
imum system voltage / Open circuit voltage of the
module) – 1) at standard condition, AM1.5G, 25
degrees temperature, 1,000 W/m
Connect modules in parallel to increase current.
Connect wires from the positive terminal of the one
module to the positive terminal of the next module.
Do not connect modules in parallel without using a
connection box. The number of parallel strings de-
pends on the system integrator’s requirements and
the inverter ratings.
These modules contain factory installed bypass
diodes. If these modules are incorrectly connected to
each other, the bypass diodes, cables, or junction
box may be damaged.

The term “array” is used to describe the assembly of
several modules on a support structure with associated wiring. Use copper wire that is sunlight resistant
and is insulated to withstand the maximum possible
system open circuit voltage. Check your local codes
for requirements.
Use system wiring with suitable cross-sectional areas
and connectors that are approved for use at the
maximum short-circuit current of the module.
The maximum open circuit voltage of the system
must not be greater than the specified maximum
system voltage for the module.
When reverse currents can exceed the value of the
maximum protective fuse marked on the back of the
module, a properly rated and certified over current
device (fuse or circuit breaker) must be connected in
series with each module or string of modules.
The fuse used is a glass / HRC type of rating 15
Amps. The fuse rating has to begreater than or equal
to 135 % of the module’s short circuit current.
The rating of the over-current device shall not exceed
the value of the maximum protective fuse marked on
the back of the module.
Match the polarities of cables and terminals when
making the connections; failure todo so may result in
damage to the module.
Connecting modules in reverse polarity to a high
current source, such as a battery, will destroy the
bypass diodes and render the module inoperative.
Bypass diodes are not user replaceable.
The junction box is under no circumstances being
opened. Opening the junction box may void the
warranty.
Modules with a suspected electrical problem should
be returned to Bosch Solar Energy AG for inspection
and possible repair or replacement as per the warranty conditions provided by Bosch Solar Energy AG.
8 Grounding 9 Diodes
Bypass Diodes
Important Notice!
Bonding connection
Module frames should be connected to an earth ground
for safety and protection from lightning. A good connection between the grounding hardware is essential for an
effective ground. The anodization on a module frame
provides a coating to minimize the corrosion due to
weather and it acts as a barrier that reduces the effectiveness of the grounding connection. For an adequate
ground, the grounding hardware should pierce the anodization layer.

When the modules are shaded partially, it may cause
reverse voltage across cells or modules, because the
current from other cells in the same series is forced to
flow through the shaded area. This may cause undesirable heating to occur. When a bypass diode is wired in
parallel with the series string, the forced current will
flow through the diode and bypass the shaded module,
thereby minimizing module heating and array current
losses.
The use of a diode to bypass the shaded area can minimize both heating and array current reduction.
All Bosch Solar Energy AG modules are equipped with
factory installed bypass diodes. The factory installed
diodes provide proper circuit protection for the systems
within the specified system voltage, so that you do not
need any other additional bypass diodes. If your system
specifications require you to add or change diodes,
please contact authorized Bosch Solar Energy AG representative for recommendations for the proper diode type.
Blocking Diodes
Blocking diodes are typically placed between the battery
and the PV module output to prevent battery discharge
at night. Bosch Solar Energy AG modules do not contain
a blocking diode when shipped from the factory. It is
recommended that a charge controller be used to prevent the batteries from being overcharged and discharged at night.
10 Maintenance
away by periodic rainfall, but in some instances some
maintenance is recommended to clean the surface of
the glass with water and a soft cloth or sponge. A
mild non-abrasive detergent may be applied for per-
sistent dirt.
However it is advisable to perform periodic inspec-
tion of the modules for damage to glass, back-skin,
frame, junction box or external electrical / loose
connections and corrosion by the authorized profes-
sional.
No aggressive and abrasive cleansers or chemicals
should ever be used on the coated front glass. No
alkali based chemicals should be used, including
ammonia based solutions.
Always wear rubber gloves for electrical insulation
while maintaining, washing or cleaning modules.
Once a year, check that growing foliage has not
caused module shading. Correct if this condition has
occurred.
As required, check that the system voltage and cur-
rent output (or power output) is consistent with the
expected output. Such a check will help to determine
if array cleaning is needed, if there are loose or cor-
roded connections, or if there is a component prob-
lem.
Warning: Do not attempt to clean a module with a
broken glass over or a perforated backsheet. Such a
module can present a serious shock hazard.
