General
The installation must only be carried out by competent
personnel.
The enclosed materials are those required for the install-
ations described (see page 12),. In special cases, these
may need to be supplemented. If in doubt, contact your
supplier. Information regarding applicable standards and
regulations must be obtained prior to the installation and
commissioning of the solar panel system. The electrical
installation, and notification to the power supplier, must
be carried out by a qualified electrician. The form for the
inverter must be enclosed with the notification Please
note that commissioning the installation before the
power supplier has given its approval is not permitted.
NOTE
Installation of a solar panel is an extensive in-
tervention on an existing roof. The roof cover-
ing, particularly on converted and inhabited loft
spaces or where the roof's minimum angle is
undersized (relative to the covering), may re-
quire further measures against moisture be-
cause of wind pressure and drifting snow, this
must be evaluated by the installer on a case to
case basis. The roof design must be able to
handle the wind and snow loading that can
occur in the region.
STATIC LOAD
The installation is only permitted to be performed on
roof surfaces or support structures with sufficient carry-
ing capacity and strength. If necessary, the static load
capacity of the roof and roof structure must be investig-
ated before the solar panels are installed. Great import-
ance should be placed on the condition of wooden roof
structures and the possibilities for screwing the
mounting devices for the solar panels to the structure.
The roof structure must be reinforced if necessary. In-
spection of the whole solar panel installation in accord-
ance with DIN 1055 part 4 and 5, or in accordance with
country-specific regulations, is required, in particular in
areas that experience snowfall and strong winds. The
characteristics of the installation’s location (prevailing
wind direction, whirlwinds, etc.) must also be included
in the calculation/estimate if these could involve in-
creased loads. The solar panels must be installed so
that snowdrifts resulting from snow guards or due to
special conditions in the installation location cannot occur
in the vicinity of the solar panels.
The distance from the outer edges of the roof must be
at least 0.35 m at the sides of roofs and 0.2 m at ridges
and eaves, in order to reduce the risk of the wind ripping
the solar panels off.
The installation system according to DIN 1055 part 5 for
snow zone II is intended for use up to 400 m above sea
level. If the installation is made on a tiled roof, it is re-
commended that the snow is cleared if it reaches a
depth of more than 30 cm on the solar panels (NOTE!
If the snow has melted, been packed down and then
more snow has fallen and so the density has increased,
the snow may need to be cleared - even though it is not
30 cm deep.)
If there is a risk that the snow will slide down onto the
panels and in particular behind the rear of raised panels,
snow guards must be installed to prevent this.
Also ensure that the material under roofs with roof tiles
is sufficiently stable to support the roof mounting points.
Otherwise the roof must be reinforced. The installer
must evaluate this and make a decision. If in doubt, a
structural engineer needs to be consulted. We also re-
commend that the roof tiles should be ground down so
there are no point loads between the roof and the roof
brackets. The minimum distance between roof tiles at
overlap points and the underside of the brackets is 3
mm, in order to allow for any movements in the
mounting system due to the loads that can arise.
SAFETY INSTRUCTIONS
• Safety regulations for working on roofs and similar
structures must be followed.
• Protection against falling parts must be installed. This
is particularly important in locations where people pass
below the roof/building.
• Personal safety equipment and/or scaffolding must
be used when working on roofs, according to applic-
able regulations.
9Chapter 3 | InstallationNIBE PV solar cell package
3 Installation

• Suitable measures must be taken during installation
to ensure that the solar panel does not come loose
and fall.
• Observe the safety distance to live conductors.
Installation and
positioning
Using the map and the diagram, it is possible to estimate
the annual value of the insolation on the surface where
the solar panels are placed.
100% is the insolation at a horizontal surface. The angle
of inclined surfaces is 45°.
The diagram shows insolation as a percentage of global
radiation in relation to surfaces at various orientations
and angles.
The map shows lines with the same global radiant flux,
i.e. the insolation measured at horizontal surfaces.

1. Calculate the annual solar radiation using the map.
The specific solar radiation for the installation is ob-
tained as a percentage, based on the location of the
solar panel according to the diagram.
2. Multiply the results by the installation’s peak output
(e.g. 3.2 / 6.4 / 9.6 / 12.8 / 16 / 19.2 / 22.4 kW).
3. Multiply the result 2 by a constant 0.9 to calculate
the energy production in kWh/year (with a reserva-
tion for shade, dirt and snow coverage).
Examples: Prague, 6.4 kW, 45°, installation south
(112 %).
1120 x (112/100) x 6.4 x 0.9 = 7225 kWh/year

Functions
MYUPLINK / NIBE UPLINK
With NIBE Uplink and the Internet, you can obtain a
quick overview and the current status of the solar panel
system on your property. You obtain comprehensive
and good supporting data, where you can see the cur-
rent power and history. In the event of any malfunction,
you also receive an alarm directly in the app, which al-
lows you to take prompt countermeasures.
WIFI COMMUNICATION MODULE CMO 11
/ CMO 22
With this accessory, you can connect the inverter to its
portal without NIBE Uplink.
CMO 11/22 communicates with your home network via
wifi.
See separate manual for more information and installa-
tion.
CMO 11 is used for inverter PVI 10 and CMO 22 is used
for PVI 20.
11Chapter 3 | InstallationNIBE PV solar cell package

Installing solar panels
in several groups
Examples of possible combinations per ten panels:
To reduce the risk of damage to the electric cables
between the groups of solar panels, these can be run
underneath the roof tiles or ceiling. To prevent moisture
penetrating under the roof tiles or through the damp
barrier at the holes for the electrical cables, diffusion
sealed lead-ins must be fitted.
Make sure that the cabling is properly secured so it does
not hang down and risk chafing.
Horizontal installation
The rails are installed vertically in the case of horizontal
mounting.
Specially adapted roof brackets for tiled roofs, sheet
metal roofs, felt roofs or seamed sheet metal roofs. The
type of roof bracket to be used must be specified when
ordering. If the panels are installed in a different forma-
tion, additional mounting materials may be required.
Caution
Additional connectors and mounting materials
may be required to install solar panels in differ-
ent groupings.
ADDITIONAL PANELS
Each package can be expanded with additional panels.
This means that you have extremely good flexibility, al-
lowing attractive roof installation.
Example
6.4 kW package installed on roof that is expanded by
e.g. four solar panels (7.7 kW)
6.2 kW package installed on roof where you have de-
cided not to install e.g. two panels (5.8 kW).

Number of solar panels per string and per
package
The table shows how many panels you can have per
string, as well as how many panels are standard and
how many the inverter can cope with. The inverter has
dual trackers, allowing the installation of different num-
bers of panels per string. If the number of panels is not
sufficient to achieve the minimum number for two
strings, you have to install all the panels in one string.
