Men checking the solar tracking system in a photovoltaic system

Solar tracking Get the most out of the sun

The yield from solar panels can be optimized with the help of a single- or double-axis tracking system. Exact tracking aligns the solar cells to the sun so that sunlight invariably falls perpendicular to the solar panels.

This guarantees optimum power generation. Continually monitoring the system status is of great importance in this regard. With software and hardware from Phoenix Contact, you can implement an efficient and reliable monitoring system for your solar tracking park.

Your advantages:
✔ Quick startup via web browser and function block libraries
✔ Remote access to your tracking park over Ethernet or a cellular network
✔ Ideal, motor-driven alignment of your photovoltaic panels by using solar altitude calculations

Drive control

Small-scale controllers with an integrated Modbus interface are ideal for controlling tracking systems.

Step motor drivers and frequency converters can be connected directly without any additional modules. Analog or incremental input channels are available for position detection.

Motor starter for tracking photovoltaic panels

Durable motor starters are ideal for tracking


The hybrid motor starter offers four functions for tracking the photovoltaic panels: forward running, reverse running, motor protection, and emergency stop.

In comparison to mechanical contactors, the motor starter is significantly more durable, saves space, and can be wired quickly.

Complex function blocks for solar altitude calculation

Function block libraries

Phoenix Contact provides a comprehensive library with complete function blocks. This includes, among other features, complex blocks with DIN/NREL algorithms for solar altitude calculation and for monitoring the photovoltaic trackers.

It ensures that the photovoltaic panels are always aligned perfectly with the sun at any time of the day or year and provide maximum yield.

Efficient open and closed-loop control of solar tracking systems

Increase the yield from your photovoltaic system by systematically tracking photovoltaic panels.
