VI. OPERATION AND MAINTENANCE
Regular maintenance of the modules is not mandatory. However, it is recommended to perform regular inspec-
tion and maintenance of the PV modules.
The PV modules should be inspected visually for any
damage or other conspicuous features. In particular
the module surface as well as the junction box need
special attention. Additionally, the electrical connec-
tions should be examined for loose connections or
other conspicuous features.
Disclaimer:
DAS Energy is not liable for any damage to the substrate, on which the modules are bonded on, or
the modules themselves resulting from the dismantling of certain modules.
The DAS Energy PV modules operate efficiently even if
they are never cleaned. Due to the special soil-resistant
surface of the DAS Energy modules, dirt and grime are
usually washed away by rain. Nevertheless, the output
power can be increased by removing dirt on the mod-
ule surface. Dust, dirt, or other residue on the module
sur face can be regularly washed away with water.
Stubborn dirt can be removed with a soft cloth (dry or
moist with lukewarm water).
Please observe the following:
In case of damages or defects of the modules their dismantling or rather replacement may be necessary. The
dismantling of DAS Energy modules is possible at both screw-fastened mounting and bonded mounting.
Avoid cleaning the modules on hot sunny days, in
the middle of the day or when there is high irra-
diation lev els and high temperatures. The module
temperature should be between 10° and 30 °C.
Do not use micro-fiber cloths, scrapers (or other
meal tools), or high-pressure water cleaners.
Do not use aggressive cleaning agents, abrasive
cleaners, tensides or other chemicals.
Remove snow and ice without force (e.g. with a very
soft broom in order not to damage the protective
layer of the photovoltaic module).
Always wear rubber gloves whilst servicing, wash-
ing, or cleaning the modules to insulate and protect
your self from electric shock.

MODULE REPLACEMENT / DISMANTLING
Disconnect the MC4-Evo2 coupler connections of the PV module which should be dismantled or rather replaced
with the connected, adjacent PV modules according to V. Electrical installation: Connector.
DISCONNECTING THE MC4-Evo2 COUPLER CONNECTION
Before the dismantling of certain module or any other modification of the PV system please make
abso lutely sure that the electrical system is without voltage and secured against unauthorized ac-
tivation. The electrical connectors may never be disconnected under load. Non-compliance can be
highly dangerous!
