In is necessary to ensure that all mountings are properly installed to protect the wiring from
moisture and damage.
UV-resistant cables with a minimum cross-section of 4mm² must be used.
The heat resistance of the cables must be at least - +85°C.
Diodes
Bypass Diodes
If the modules connected in the series are partially shaded, a reverse voltage can occur in the
cells or modules as the electricity from the other cells of the same series connection
necessarily flow through the partially shaded area. As a result, undesired heat may develop.
By using a diode to bypass the shaded area, the heating as well as the reduction of electricity
in the affected group is minimised.
Every module from PV Products GmbH is equipped with bypass diodes during manufacturing.
The diodes installed by the manufacturer provide suitable protection of the respective circuit
of a system within the given system voltage so that additional bypass diodes are not
necessary.
Certifications
The modules shown in table 2 are certified by TÜV and meet the requirements according to IEC
61215, IEC 61730-1 and IEC 61730-2 and carry the CE marking.

Maintenance
To maintain optimal output performance of the photovoltaic modules, a certain level of
system maintenance is recommended.
Contamination on the surface of the module may reduce the output.
Cleaning the surface of the module with water and a soft cloth or sponge is recommended.
Persistent dirt can be dissolved with a mild, non-abrasive cleaning agent.
Inspecting the electrical and mechanical connections once a year is recommended.
If you intend to perform electrical or mechanical inspections or maintenance, it is
recommended that you commission an authorised specialist to avoid the threat of an electric
shock or injuries.
Returning modules from PV Products GmbH is only possible following written consent from
PV Products GmbH.
