The First Solar Power Plant in Ukraine Using a SOLARsk Tracker System

 SOLARsk has completed the construction of the first solar power plant in Ukraine built on the domestic HSAT HORIZON STR-111 tracker system. This project marks an important milestone in the development of solar energy in Ukraine and demonstrates the potential of Ukrainian technologies.

Project Capacity and Scale

• Installed panel capacity: 997.84 kW
• Allowed (connected) capacity: 800 kW
• Land area: 1.7478 ha
• Number of installed trackers: 38 units of HSAT HORIZON STR-111

The construction of the plant took only five months — a true testament to the efficiency and professionalism of the SOLARsk team.

The HSAT HORIZON STR-111 tracker system is an adaptive, self-sufficient solution that automatically follows the Sun, adjusting the tilt angle of the photovoltaic modules throughout the day.

Thanks to its proprietary control algorithm, the system provides up to 20% higher efficiency compared to static structures, especially during peak electricity price hours — in the morning and evening. This not only increases energy generation but also optimizes energy sales on the market, which is critical in the context of dynamic pricing and new electricity price restrictions in Ukraine.

Project Uniqueness

This plant is the first in Ukraine built using a domestic single-axis tracker. It demonstrates how transitioning from traditional fixed systems to dynamic tracker technologies can enhance the profitability and competitiveness of renewable energy facilities.

“The market is changing, and we must stay one step ahead. Our trackers allow us to maximize solar potential and earn more precisely during the hours when electricity is most expensive,” said Yevhen Yaremenko, CEO of SOLARsk.

The use of the HSAT HORIZON STR-111 system helps reduce CO₂ emissions by approximately 20% more than static solar installations of the same capacity.

Project Payback Period — up to 7 years.

The company plans to expand the plant and integrate a BESS (Battery Energy Storage System), creating an efficient synergy of energy generation and storage for even greater stability and profitability.

Challenges and Achievements

Constructing the plant was a true test for the team: from improving the design of individual components to developing software for tracker management.

However, the result exceeded expectations: the facility operates stably, and the system demonstrates high reliability and precise solar tracking.

“HSAT HORIZON STR-111 is a product made in Ukraine for the world. We are proud to usher in a new era of tracker systems on the Ukrainian market,” said Andriy Antonov, Technical Director at SOLARsk.
