1 Notesonthisguide
Thank you for choosing Centrosolar S-Class Integration/S-
Class Integration Deluxe modules. If you have any ques-
tions regarding the system components please contact
our technical support: [phone].
The maintenance and operation of a PV system require
a sound technical knowledge. Therefore, any work on the
system may only be carried out by qualied and authorized
personnel. Make sure to read these assembly instructions
carefully before installing, commissioning or servicing the
system, and store these instructions in a well accessible
location. This guide is part of the product. It is applicable
only to S-Class Integration/S-Class Integration Deluxe so-
lar modules by Centrosolar AG. Please pay special atten-
tion to the notes on the safe use of the system. Centroso-
lar is not liable for any damage resulting from disregarding
this guide.
Targetgroups
The target group of this guide, especially chapter 5 (Safe
installation) are skilled craftsmen. All relevant informa-
tion for the operator can be found in section 8 (Mainte-
nance and cleaning).
Information regarding your safety
and the protection of the device is
highlighted.
Pleasenote:
Disregarding the instructions of this installation guide may
void any warranties, guaranties and product liabilities.
2 SystemS-ClassIntegration(Deluxe)
2.1 Description
The S-Class Integration (Deluxe) mounting system replac-
es the conventional roong of pitched roofs and is used for
a roof inclination of more than 10 degrees. It is laid onto
the existing roof lathing and is suitable for old and new
buildings alike.
Due to the arrangement of the system lathing, the S-Class
Integration (Deluxe) mounting system provides for a back-
side ventilation in order to cool the modules from the back.
For the electrical connection, HUBER+SUHNER prefabri-
cated connectors are used.
2.2 Tightness
The S-Class Integration (Deluxe) mounting system offers
a rain resistance which is comparable to a standard pan-
tiled roof. It does not mean that a roof is water tight! Under
certain climatic conditions, snow akes, driving rain oder
water may penetrate under the modules from the eaves.
For a proper drainage of ingressed water or condensate,
an intact sub-roof is required. If not available, such a roof
must be erected/retrotted prior to installation of the mod-
ules.
2.3 Sub-roof
The general rules, which are valid for roofers, shall ap-
ply to the design and the backside ventilation of the sub-
roof. In order to extend the lifetime of the substructure, the
backside ventilation should be enhanced by means of the
module lathing and ventilation orices at the eaves and
ridge. In addition, backside-ventilated crystalline modules
will offer a higher yield.
A structural stability of the roof and/or the roof substructure
with regard to wind and snow load, which allows the re-
sulting loads and forces to be absorbed and transfered by
the roof substructure – the rafters, lathing and connecting
elements – is a basic requirement for the installation of a
photovoltaic system .

5 Safeinstallation
Direct-currentconnection(DC)
Since the module and string cabling will be inaccessible
after the installation of the PV in-roof system, the open-
circuit voltage of each string must be checked after it has
been laid and wired.
GroundingofthePVgenerator
A grounding of the PV generator is not mandatory. How-
ever, atmospheric inuences and reactions of the invert-
ers may lead to a charging of the metallic frames of the
generator eld to earth potential. The resulting contact
voltages are not hazardous, as the leakage currents will
be monitored by the inverter. Nevertheless, these contact
voltages can lead to startle reactions and therefore result
in "secondary damage".
Whenever persons may come into contact with the PV
eld during operation of the PV system, the metallic parts
of the generator eld must be grounded.
Overvoltageprotection
The overvoltage protection generally serves to protect the
inverter and the systems against indirect lightning strikes.
This subject will not be dealt with in detail here.
Pleasenote:
It is strictly forbidden to direct articially concentrated sun-
light onto the module or panel, as this will damage the
module.
5.1 Preliminaryremarks
 The PV generator, or the generator area respectively,
must be integrated rectangularly into the roof (see "3-
4-5 rule"). Therefore, it must be parallel to eaves and
verge.
 For non-rectangular roofs (e.g. old buildings), the PV
generator should be parallel to the verge for optical
reasons.
 Any unevenness of the roof structure must be leveled
to an extend that allows a level mounting of the mod-
ule lathing.
 The roof structure must be tted or retrotted (if re-
quired) with an intact trussed sheet.
 The screwed connections must be pre-drilled in order
to avoid splitting or breaking of the wood. Hole diam-
eter = 0.7 x screw diameter in mm.
 The module lathing must be screw fastened on the
roof lathing. Therefore, always check whether it is fas-
tened rigidly on the rafter! Please note that regular
nails (wire nails) are not allowed as fasteners. Always
use ribbed nails or screws according to DIN 1052.
 For the module lathing, 38 mm x 58 mm roof laths
must be used.
 Prior to module installation, the DC main lines must
be laid according to the module connection diagram
prepared for the respective site.
 The module connection cables must not be subjected
to tensile stresses.

RectangularintegrationofthePVgenerator
The 3-4-5 rule is a good way to determine the right angle.
Divide a cord by knots or marks into sections with a pro-
portion of 3 to 4 to 5 (e.g. 3 meters, 4 meters, 5 meters).
Stretch the cord on the roof as shown in the gure. The
knots must be placed in the corners. The angle between
the sides 3 and 4 is a right angle.

5.2 Installationofthemodules
Figure 1
In order to screw fasten the roof lath (a) for the
lower roof connection, a lath thickness corre-
sponding to the existing roof lathing must be
used. The distance between the upper edge of
the roof tile and the lower edge of the roof lath
should be 180-200 mm. The roof lath end must
be located outside the PV generator and placed
on rafters.
Figure 2
To fasten the roof connection, use 4.5 x 35 Spax
screws. The right hand and the left hand edge
should overlap the PV generator eld by ap-
prox. 250 mm. The overlapping onto the roof
tiles should be approx. 80-100 mm (overlapping
joints of roof connection approx. 100 mm for
new rolls).
Figure 3
Measure the location of the rst module lath

Vertical position: 20 mm overlapping on addi-
tional roof lath (see above).
Use 5 x 10 Spax screws (not supplied) for fas-
tening.

When installing with a horizontal orientation,
make sure that the "right hand" roong sheets
sufciently reach under the neighboring roof
tiles. According to type, the left hand hanging
cams of the roof tiles must be cut off, or the
neighboring roof tiles must be trimmed. In this
example, a half roof tile is used.
Figure 5
In order to install the supporting structure, place
the module laths "Field" and "Frame" (prepared
with brackets) onto the roof and position them
horizontally at a distance which roughly corre-
sponds to the module width of the rst module
lath and vertically approx. 100 mm below the
nal position.
