Ukrainian trackers enter the market: a new stage in the development of solar energy

The Ukrainian company SOLARsk has completed the construction of the country’s first solar power plant built on the basis of a domestically produced tracker system — HSAT HORIZON STR-111.
This project has become a landmark case for the industry, demonstrating that innovations created in Ukraine can be an effective tool for improving the productivity, flexibility, and profitability of solar power plants.

A new standard of efficiency

The plant has an installed panel capacity of 997.84 kW and a permitted (connected) capacity of 800 kW.
Located on a 1.7478-hectare site, the facility is equipped with 38 units of HSAT HORIZON STR-111 trackers.
Construction lasted only five months — a short cycle that highlights the team’s efficiency and the technology’s readiness for scaling.

The core element of the system is a single-axis tracker that automatically orients itself toward the sun, adjusting the tilt of the photovoltaic modules throughout the day.
Thanks to its proprietary control algorithm, the HSAT HORIZON STR-111 increases energy output by up to 20% compared to fixed structures, especially during peak electricity price hours — in the morning and evening.
In today’s market, where prices fluctuate hourly, this means not only more kilowatt-hours but also higher profitabilityfrom day-ahead market sales.

Ukrainian technology, designed for Ukrainian conditions

The HSAT HORIZON STR-111 tracker is a fully localized innovation — from its mechanical design to its control software.
The SOLARsk team tailored the system for Ukraine’s climate: resistant to strong winds, temperature variations, and capable of operating autonomously, reducing maintenance needs.

The engineers also developed a tilt angle control algorithm that considers not only the sun’s position but also economic indicators — such as spot price dynamics.
This allows the system to optimize generation in real-time market conditions. Technologically, it brings the station closer to the concept of a “smart” solar plant, where generation is synchronized with demand and price.

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

Innovation as an economic driver

The use of trackers in solar power is not new globally, but for Ukraine, this case marks a new chapter.
Until now, most local stations were built on fixed structures, which simplified installation but limited generation.
The implementation of HSAT HORIZON STR-111 makes it clear: the transition to dynamic systems is the next stage of market maturity.

An increase in energy generation of up to 20% translates into a payback period of under seven years, even under the current regulated tariff environment.
Moreover, tracker systems allow for an estimated 20% reduction in CO₂ emissions compared to equivalent static installations — due to more efficient land and solar resource use.
This strengthens the argument for adopting such systems not only for private investors but also for municipal and corporate projects aligned with ESG strategies.

From pilot project to technological norm

According to SOLARsk, the process of developing and implementing the HSAT HORIZON STR-111 presented a major engineering challenge — from structural calibration to control software development.
The result exceeded expectations: the system operates stably and demonstrates high tracking precision under various conditions.
The next step for the company is the integration of Battery Energy Storage Systems (BESS) — combining tracker-based generation with flexible storage to balance daily load fluctuations.

“HSAT HORIZON STR-111 is a product created in Ukraine for the world. We’re proud to be launching a new era of tracker systems in the Ukrainian market,”
said Andrii Antonov, CTO of SOLARsk.

Why it matters for the market

The emergence of a domestic tracker technology is of systemic importance for Ukraine’s energy sector.
First, it reduces dependence on imported equipment, which has dominated the country’s solar supply chain.
Second, it creates local added value — from component manufacturing to engineering services.
And third, it opens the door for scalability: HSAT HORIZON STR-111 can be deployed across a wide range of projects, from commercial to municipal installations.

For investors and developers, this represents a new model — higher generation output on the same land area with lower long-term capital costs.
For the state, it’s an opportunity to build a domestic technological segment in renewable energy, fully aligned with Ukraine’s strategy of transitioning to 100% renewables.

Perspective: from pilot to series production

Industry experts note that such projects could form the foundation for developing a serially produced Ukrainian solar engineering product.
This opens the way for exports, partnerships with international players, and financing for localized renewable technologies.
SOLARsk plans to expand the current station and test new tracker configurations with enhanced energy efficiency.
Thus, HSAT HORIZON STR-111 may become the first step toward establishing an industrial benchmark for Ukraine’s solar sector.

For Global 100 RE Ukraine, this case is proof that the country’s renewable energy sector has entered a new phase of technological maturity.
Local solutions, strong engineering expertise, and a systemic focus on efficiency are building the foundation for a sustainable, climate-neutral energy future.
Innovations developed in Ukraine hold not only practical but also strategic value. They show that energy transformation is achievable — even under challenging conditions — when engineering vision, business motivation, and market support align.

Global 100 RE Ukraine sees the advancement of such technologies as a key pillar of national energy resilience.
