Please read this installation and operation guide completely and carefully before you transport, install and operate the solar modules! It contains (among other information) important safety information which you must know. When solar modules are used without observing all instructions in this guide, all warranty and guarantee claims towards us shall lapse. We reserve the right to update the information in this guide without prior notice.

The installation, setup and commissioning of solar mod

ules requires a high level of expertise and experience, and therefore must be performed solely by specialists (e. g. a specialist electrician) who can verify the successful com

pletion of suitable training.

Safety guidelines | 3

2 Safety guidelines

The setup and commissioning of the electrical system may only be performed by a specialist electrician in observance of the following guidelines, since improper performance of this work can lead to damage and injury. When performing work on solar generators – primarily on roofs – suitable safety precautions (e. g. fall arresting devices) must be used. The regulations set forth by Employers‘ Liability Insurance Associations must abso

lutely be observed. For your own safety and to safeguard your solar module, please observe the following safety

guidelines:

 During the setup and maintenance of solar modules,

the valid regulations and safety guidelines for the installation of electrical devices and systems, as well as the regulations set forth by the competent energy supply company for the parallel grid operation of solar power systems.

 Prior to setup, the solar module must be inspected

for mechanical soundness. Damaged solar modules (e. g. modules with broken glass, damage to the insu

lation ﬁlm at the reverse) may not be set up.

Damage to the insulation ﬁlm at the reverse has se

vere potential consequences (delamination, endangerment of life and health).

 You should mount the solar module in such a way that

it is not aﬀected by shade (even temporary or partial shade caused by dormers, trees or similar obstacles). Shaded PV arrays can lead to PV generator failure and losses in performance.

 The serial connection of the modules (addition of the

module voltages) may result in voltages above the safety extralow voltage of 120 V DC!

 The modules have been classiﬁed for Application

Class A: dangerous voltage (IEC 61730: 50 V, EN 61730: greater than 120 V)

 Even when the light intensity is low, one must reckon

with the full atrest voltage of the modules – that is to

Important notice!

say, in the course of setup, one must always exercise

the greatest caution with regard to electrical faults (e. g. short circuits). 

The separation of conductors which carry direct cur-

rent can lead to light arcs. Therefore, prior to perform-

ing any work on the solar system – particularly prior to

separating the plug connectors in the direct-current

circuit – it is essential to disconnect the frequency

inverter from the alternating-current grid.  For roof-mounted systems, the modules must be

attached above a ﬁreresistant surface.  Solar modules may not be installed near easily-

ﬂammable substances, gases or vapors.  The guidelines on ﬁres in electrical systems

(e. g. VDI 3819) apply hereto. 

The maximum permissible totalsystem voltage for

the frequency inverter may never be exceeded. In

addition, due to the negative temperature coeﬃcient

of the solar modules, the atrest voltage of the total

system at the minimum permissible temperature

must also be calculated (see data sheet and module

type sign).  The solar module is to be treated as a glass product

and may therefore not be used or walked on under

any circumstances in the transport container or used

as a placement area (e. g. for toolboxes), since this

can lead to visible or even invisible damage (e. g.

microcracks in the cells and with that, a premature

drop in output – among other faults).  The module frames may not be drilled, nailed or

welded to a contact surface.  The solar modules may not be held or transported by

their connector cables or by the connector socket.  Solar modules may never be left standing freely or

unsecured.  The safety guidelines set forth by the manufacturers

of other components of the solar system must be

followed.  The drainage drill holes in hollowchamber frames may

not be covered. Bosch Solar modules meet the building regulation list

requirements for PV modules having a maximum glass

surface of by 2 m² as established by the DIBt

(Deutsches Institut für Bautechnik, [German Institute

for Building Technology]).

3 Positioning guidelines

In order to achieve the highest-possible annual energy yield, we recommend positioning the module so as to fulfill the following criteria: You should mount the solar module in such a way that

it is not aﬀected by shade (even temporary or partial shade caused by dormers, trees or similar obstacles). Shaded PV arrays can lead to PV generator failure and losses in performance.

Prerequisite to installation on a flat roof is a hard

roofing seal per DIN 4102, Parts 4 and 7 – if there is uncertainty about the roofing surface, please ask your roofer.

When arranging modules in open field systems, suit

able measures must be taken to ensure that readily ignited organic materials (e.g. dry grass, hay) are permanently removed from the vicinity of the system.

Position the front of the solar module, so that it faces

the Equator.



Select the angle of inclination according to the local and structural factors (30° ± 15°). You will find spe

cific data on optimum module positions in the pertinent specialized literature. The calculation of the angle of inclination can be based on the following formula: angle of inclination = latitude of the posi

tioning locality - 20°.

All modules of a photovoltaic generator are to be

aligned at the same angle (horizontal as well as vertical). In the event of angle deviations, separate frequency converters are to be designated.

In order to ensure sufficient selfcleaning, the angle of

inclination must amount to at least 10°.

For optimized selfcleaning, a 15° minimum angle of

inclination is recommended.

Always ensure that the reverse side of the module is

well ventilated.

Attention!

Due to heat accumulation under the modules there is an increased fire hazard associated with rooftop installations which do not meet the aforementioned requirements.

You should mount the solar module in such a way that

it is not affected by shade (even temporary or partial shade caused by dormers, trees or similar obstacles), since this may lead to damage in the solar module, such as formation of hot spots, PV generator failure and losses in performance

Important note!

Take into account additional loads produced by the PV system's weight and structural mount when carrying out the structural analysis for the overall structure.

Modules must be mounted so that the rear of the

module does not come into contact with objects behind it, even if a mechanical load is applied.

To avoid increased strain of the modules due to wind

load, it is necessary to observe minimum distances from building boundaries according to DIN 1055-4.

A concentration of sunlight on the modules via mir

rors or lenses is prohibited.

Avoid contact with salty water! The crystalline solar modules made by Bosch Solar

Energy have been tested in accordance with the following norms for their response to contact with

salty air: – IEC 61701: 1995 – DIN EN 61701: 2000-08 – IEC 60068-2-52.

Please observe the test conditions indicated in the norms when using the modules in salty air.

The system installer or operator must provide an

analysis of the building structure’s stability, deflec-

tion and loads.  Mount the modules on an adequately dimensioned,

permanently corrosion resistant, stable substructure.  The installation proﬁles are to be positioned in paral

lel to one another.  The fastening points are to be aligned symmetrically

(see Figure 1).
