Solar modules
Solar modules may only be used if they hold the following valid certification:

IEC 61215/IEC 61646 and protection class II/IEC 61730
Framed solar modules
Please note that the guarantee for the solar modules will be rendered void if modifications are made to the
module frames (e.g. by drilling additional holes). In order to comply with warranty conditions, the
installation instructions of the respective solar module manufacturer must be strictly observed.
Lightning and overvoltage protection
The lightning and overvoltage protection of the PV system must comply with the current specifications of

DIN/VDE 0185 parts 1 to 4

DIN/VDE 0100 part 712

VdS 2010.
Please refer to the specified directives and standards for detailed information. We generally recommend
integrating the mounting system and the module frame into the on-site equipotential bonding and using
overvoltage protective equipment.
Equipotential bonding is always required if the solar modules used do not comply with protection class II
and/or transformerless inverters are used.
The cross-section of the equipotential bonding conductor must correspond to the cross-section of the DC
main cable; however, it must be at least 6mm² (copper).
If the building is equipped with a lightning protection system and the PV generator is not located within the
protective area of the interception device, the module frame and the mounting system must be integrated
into the external lightning protection system and additional overvoltage protective equipment must be
installed.
The electrically conducting connection must have a minimum core size of 16mm² (copper). Please obtain
information on the currently applicable, technological standards!
