We understand the importance of each additional percentage of energy generation for our customers, so the "system efficiency" parameter is a result of complex works on each system component as well as the application of modern materials, design and production technologies, anticorrosive protection, electronic control systems. The chart above illustrates the difference in energy generation when using different types of PV module mounting systems at the same installed capacity of the solar power plant.

The dynamic PV module mounting systems allow using sun energy for power generation in the most effective way comparing to the static systems. Currently, Ukrainian System Solar has a whole range of dynamic PV mounting systems - single- and double-axis solar trackers.

Benefits of using single-axis tracker

A single-axis solar tracker is a single-support dynamic PV mounting system that contains 8 sections of 60 PV modules in each. These 8 sections form a cluster of 480 PV modules of 140 kW installed capacity located on an area of 0.15 hectares. Moreover, it is possible to adapt the solar tracker to the land area of almost any shape.

Control system

Maximum efficiency

The single- and double-axis solar trackers are equipped with the integrated control system and a comprehensive sun irradiation sensor that has proved itself at the projects delivery. To improve the reliability, the system operates in two modes: active and passive.

In regular (active) mode, the system using a comprehensive sun irradiation sensor continuously analyzes the state of the sun and irradiation and directs the array of PV modules to the area of the maximum energy saturation, taking into account the diffused and reflected light. That is especially important in cloudy and gloomy days when the sun is covered with clouds.

In passive mode, the system starts to operate in case of the sun irradiation sensor’s failure. In such case, the tracker operates on the astronomical calendar.

Thus, automatically changing the installation angle of the PV module array, with help of the integrated control system, the double-axis solar tracker provides an annual increase in energy generation compared to a static system of up to 50%, and a single-axis tracker - up to 15-17% per annum.

Operational reliability

The complex control system provides reliable protection against wind and snow loads thanks to the integrated wind and snow sensor.

When the wind load exceeds the allowed values, the control system sets the PV module array to the feathering position (the smallest opposing the wind flow).

When the snowfall exceeds the defined allowance, the control system sets the PV module array to the position for the snow removal from its surface.





The system has 24/7 web monitoring function over the tracker’s operating condition.

The information on the tracker's technical condition is automatically transmitted by the control system to the dedicated server via the GPRS channel and displayed in the client's personal account on the company's web page. Thus, the solar tracker owner can remotely monitor its operation 24/7 from any location. The following options are available:

Materials and standards

Aluminum elements of static PV mounting systems are manufactured of the high-quality extruded aluminum profile of AlMg0.7Si 6063T66 based on EN 755-2.

Steel elements are made of С235 steel under the National State Standard 27772-80 and covered with a protective hot dip galvanizing coating with a thickness of up to 70 μm. The coating meets the requirements of the National State Standard 9.307-89.

Fastening elements of mounting systems are supplied in options:

A selection of materials used in the mounting systems fully eliminates corrosion degradation, including by electrochemical corrosion for at least 25 ÷ 30 years. A similar result has been achieved through a careful selection and reasonable combination of materials, as well as the use of protective new generation zinc- dispersed coatings Delta MKS®.

Static PV mounting systems manufactured by Ukrainian System Solar meet the requirements of the following standards:
