Please observe the specific instructions for handling solar modules with AR glass.
Compared with non-coated glass, the surface of AR glass has a similar resistance to mechanical influences. The
resistance to corrosion and chemical influences is considerably higher than with non-coated glass. The AR layer should
be handled with the same care to avoid any damage to it. Due to its special reflective properties, light soiling is more
noticeable than on non-coated glass. In particular, fats/oils are visible even in small amounts and change the reflection
and thus also the appearance of the module. In order to avoid these marks, the modules should only be touched with
clean gloves or suction cups with covers.
4. Information on the module
Certification and Performance Data
For the performance data and instructions on certificates for our brand modules, please refer to the datasheets for
the respective series.
Use
Please observe the following points in particular for the use of our brand modules:
Installation or operation of the solar modules is permissible up to an altitude of max. 2000 m above sea level.
The function of the modules is tested at an ambient temperature of -40 to +40°C or an operating temperature
of -40 to +85°C. This area should be adhered to.
The solar module is not suitable for use in seawater.
When installing in salty air, functional earthing must be provided.
The module must not be subjected to unusual chemical loads (e.g. emissions from manufacturing plants).
Do not immerse the solar module in liquid.
Do not install the module in the immediate vicinity of air-conditioning units.
Do not use any lenses or mirrors to concentrate light (risk of overheating).
Avoid damage to the module from using carbide or diamonds.
Protect solar modules from overvoltage, e.g. voltage peaks from battery-charging devices, generators or
alternators etc. (Please ask your specialist retailer in case of any doubt).
If solar modules are connected to energy-storage devices, the safety instructions of the respective manufacturer
must be followed.
Keep children away from solar modules.
In southern regions, a PV module can supply greater power and/or a higher voltage than stated for the standardised
test conditions (standard test conditions). Therefore, to determine the voltage ratings of components, current ratings
of conductors, sizes of fuses connected to the output of PV modules, the values of I
sc
and U
os
indicated on the module
should be multiplied by a factor of 1,25. The highest rated value for overcurrent protection (reverse current resistance)
is 20 A.
5. Module installation
General instructions on module installation
All modules can be fitted both horizontally and vertically independent of the connector sockets.
The modules must not be subject to stress during installation. The modules cannot be used as a rigid linking or fixing
element.
Please be advised that the holes in the frame and in the corners must remain free in order to allow condensed water
to flow out.
Load on the modules
The load capacity of standard solar modules is independent of the installation situation and the system used. Please
observe the installation situations in the following table and the resulting maximum load capacity of the modules.
The values shown (Fig. 3) correspond to the design load in accordance with IEC 61215: 2016. The cyclical load test is
carried out according to the standard of a 1.5 times higher test load.
