7 Commissioning of the system
The commissioning of a photovoltaic system is part of the
proper and professional implementation and installation. It
must only be performed following a careful visual examina-
tion and a professional electrical inspection. Furthermore,
a report of the commissioning must be prepared.
Follow the below checklist during commissioning of the
system.
Visual examination:
Anchoring of the components to the roof structure
P P
Cable installation on modules, generator connection
P P
boxes, DC-sectioning points and inverters
Potential equalization (if applicable)

Electrical inspection
String open circuit voltages
P P
String open circuit currents (use load break switch)
P P
PV generator open circuit voltage

8 Maintenance and cleaning
This photovoltaic system requires extremely little mainte-
nance and servicing.
However, do inspect the system regularly and perform
a check every 6 months following this scheme:
Checking of the solar modules for scratches, optical
P P
changes or contamination
Checking of the module fastening, if accessible
P P
Checking of the wiring, if accessible (connection lead,
P P
fastenings, mechanical damage)
Checking of the electrical functions of all components
P P
Monitoring of the operational safety of the electrical
P P
components

claim on completeness.
Attention!
No high pressure cleaning!
Usually, the modules are automatically cleaned by rain.
With an inclination of more than 15° the modules generally
need no additional cleaning. In case the module surface
is contaminated by leaves, bird feces, pollen etc. we rec-
ommend cleaning with sufficient water without detergents.
The modules are best cleaned using a water hose and soft,
gentle cleaning equipment, e.g. a sponge or a car clean-
ing brush. To avoid micro-scratches, which may affect the
yield of the system or could lead to module damage in the
long run, the dirt must never be rubbed or scraped off the
surface in a dry state.
Please note:
Stepping onto the modules for cleaning purposes is not
allowed.
