Energy Surplus
by exact tracking technology
The sonnen_system can be employed at all places where the operation of dual-axis tracking systems guarantee both,
reliability and economy of the investment. Due to the consistent integration of high-quality components sonnen_systems are
perfectly adapted even to the demands of the most different climate zones.

sonnen_systems will typically
optimize the energy yield of a
photovoltaic unit in many ways.
The accurate tracking technology of sonnen_systems
as well as the direct and indirect cooling and the
increased self cleaning effect of the module surface
lead to additional yields of up to 45 % compared to
stationary systems.

6. Communication
Control your system –
wherever you are!
6
The integration of the SolTrk into SMA communication ensures constant control and monitoring of sonnen_systems.
Each control unit is connected with the Sunny WebBox, which represents the link between sonnen_system and the Internet.
Thus, every sonnen_system is permanently in touch with the Sunny Portal, where all data of the system are processed,
archived and visualized.
The interface of the Sunny
WebBox shows a listing of all
connected SolTrks. Here, each
system can individually be
selected and read-out.
All parameters and instan-taneous
values can be seen
at a glance. They inform you
about firmware, adjustment
angle, current and operating
mode of the sonnen_system.
Via remote maintenance,
diagnoses about function and
condition of sonnen_system
can be made. Moreover, each
system can be remote controlled
and thereby ensures a fast,
beneficial and simple service
of every sonnen_system.

7. Via our new Apple iPhone based application track_app the tracking system’s astronomical
control can be directly accessed and therewith initial operation and the complete service
can be carried out. Instant status messages on the iPhone device allow immediate reactions
from anywhere in the world.
Additionally, built-in remote diagnostics and remote functions directly process and com-plete
most messages. Even the inverters can be diagnosed from distance and their yields
7
Data exchanges between the system operator and sonnen_system can
be carried out differently. The user can directly and indirectly access all data of sonnen_system.
In case of a system outage an event log is generated automatically and immediately informes system operator
and service staff to minimize down times and deficits in yield.
are shown in real-time via the clearly laid-out display.
The Sunny Portal provides an interface, in which all operational data of the sonnen_systems are converged.
Here, tables, charts and reports are compiled to monitor, evaluate and visualize the sonnen_system.

Astronomical
Control
Each sonnen_system is equipped with a separate control unit.
Thus, one big advantage is that each system can be accessed and parametrised individually.
Only a supply cable, a feed-in cable and a communication cable are needed for the operation. Their entry
points are all at the bottom side of the SolTrk. The cable enterings are designed as PG-screwings each and
marked according to their sonnen_system configuration. Thus a simple, fast and proper connection is ensured.
This way, up to 25 sonnen_systems can be summarized in one group and multiple of such groups can be pooled
to huge solar power plants. A costly laying of control wiring thereby becomes redundant.

Cabling Communication
All devices of one sonnen_system are connected to a Sunny WebBox via RS 485 communication bus.
Every SolTrk is equipped with a COM-IN and COM-OUT plug-in to integrate them into the bus. The inverter is connected
to the appropriate SolTrk via branch line.

To prevent sonnen_systems
from shadowing each other,
sufficient amount of space per
system is needed.
The crucial factors are the
dimensions of the module sur-face
and the radiation angle
of the sunlight. As these factors
vary on type and location of
the system, we differentiate
floor space requirements for
sonnen_systems.
The rail rack of the sonnen_system
allows an extremely versatile and
flexible arrangement of all current
PV modules.
The layout of sonnen_systems can
be individually adapted to the quantity
and size of the applied module type,
and thus, the most different module
allocations can be realized.
