Extend the
lifecycle of your
PV power plant
and the warranty
of your installed
components! Our
maintenance
team inspects,
repairs and
updates your
power plant on a
continuous basis.
Our highlytrained control
room team, with
its extensive
experience in
renewable
energies,
provides
permanent
management,
monitoring,
documentation
and analysis of
your PV power
plant.
skytron PV plant
monitoring and
control solutions
are
comparatively
unique in the
young solar
market. For a
good
introduction and
to cover the
basics of our
monitoring
concept, we offer
regular training
workshops at our
head office in
Berlin.
We provide the
complete
configuration of
necessary
technology, data
communication
and data banks,
in addition to the
adjustment of
the power plant
control system to
meet the
requirements of
the local public
utility company.
F_R01-02_121205
Avoid expensive
retrofitting from
the outset depending on
the installation
site and the
applied PV plant
components, our
project
engineering team
plans all the
measurement
points that
require
monitoring.
