*SolTrk Control: *The control unit SolTrk was developed in cooperation with SMA Technology AG. An algorithm for precise solar tracking is stored in the astronomic control unit. All properties help to achieve maximum power outputs and optimum energy efficiency of the solar power systems.
*Communication:* For an extensive monitoring capability, the SolTrk control unit is incorporated in the SMA communication infrastructure. This enables remote access to the control unit via the SMA Sunny WebBox. Integration in the free SMA Sunny Portal enables long-term monitoring of the systems and their outputs.
*Safety:* The core element of the safety concept of the solar power system is the safeguard. This is responsible for smooth operation and protects the system against such things as storm damage and power supply failures.
*Foundation:* The foundation of the solar power system can take various forms such as underground concrete foundation, overground concrete foundation, screw foundation or drilled foundation.
*Output:* Depending on the installation location, the dual-axis tracking solar power system generates up to *45% more output* than optimally fixed elevated photovoltaic systems.
Dual-axis tracking unit fits 40m² (430 sq ft) of surface area may fit up to 32 modules depending on the type of module. The system includes the following:
