General information, hazard warnings and
safety advice
Do not insert electrical components into
plugs and sockets.
Ensure that all tools and working conditions
are dry.
Do not use damaged modules.
Do not dismantle modules.
Do not apply paint, adhesives or sharp
objects to the reverse side.
Ensure that the correct period of time
between switching the inverter off and
restarting it, is observed as stipulated by the
manufacturer.
The PV module may not be installed near
open flames or in the immediate vicinity of
flammable materials.
Installation of the module in corrosive saline,
ammoniacal or sulphurous areas is not
permitted.
Never separate the solar generator from the
inverter while it is connected to the power
network.
Solar modules generate electricity, even
when they are exposed to low levels of light.
Arrays of modules can cause lethal shock
and burn hazards.
Only authorized and trained personnel
should have access to these modules.
To reduce the risk of electrical shock or
burns, modules may be completely covered
with an opaque material during installation.
Do not touch live terminals with bare hands.
Use insulated tools for electrical connections.
Site selection
In most applications Schüco modules should be installed in
a location where they will receive maximum direct sunlight
throughout the year.
In the Northern Hemisphere the modules should typically face
south and in the Southern Hemisphere the modules should
typically face north.
Modules facing 30° away from true South (or North) will lose
approximately 10% to 15% of their power output.
If the module faces 60° away from true South (or North), the
power loss will be 20% to 30%. When choosing a site, avoid
trees, buildings or obstructions which could cast shadows on
the solar modules especially during the winter months when
the arc of the sun is lowest over the horizon.

Module tilt angle
Schüco solar modules produce the most power when they are
pointed directly at the sun. For installations where the solar
modules are attached to a permanent structure, the solar
modules may be tilted for optimum performance. Depending
on the application it may be better to optimize the tilt for winter
production, summer production or total annual production. The
module tilt angle is measured between the solar modules and
the ground (Figure 1). Refer to Table 1 for the recommended
module tilt angle for your site.
As a rule of thumb, the highest annual electrical production
will occur when the modules are tilted at the angle of the site
latitude. That is, the further from the equator, the greater the
tilt angle. For optimizing summer production, a lower tilt angle
(e.g. latitude -15°) may be selected. For optimizing winter
production, a higher tilt angle may be considered. Note that
the higher the tilt angle, the higher the wind loading on the
modules and the stronger the support structure will need to be.
Modules tilted steeply however, will shed snow better.

Table 1: Recommended Tilt Angles for Fixed Systems Based on
Winter Performance
When modules are tilted, be sure that any shadows cast by the
modules do not fall on other modules behind them, particularly
in the winter time when shadows are longer. This can have a
very severe effect on overall system performance.
