SUNSAY NRG — a team of experts in solar energy and battery energy storage systems (BESS) for businesses.

We provide end-to-end services: calculation, design, construction, and maintenance of solar power plants and energy storage solutions.

With more than 7 years of experience, our team of skilled engineers and managers brings deep expertise to the renewable energy sector. We have successfully delivered thousands of solar and BESS projects across Ukraine and Europe — proof of our consistent engineering quality and dedication to customer support.

Together, these systems have already generated nearly 12 million kilowatt-hours of clean energy, preventing around 6,150 tons of CO₂ emissions. Over the next 20 years, they will deliver even more — saving an additional 70,000 tons of CO₂ from entering the atmosphere.

Our mission is clear: to accelerate the global transition to sustainable energy. By combining solar power with smart storage, we help businesses achieve energy independence, resilience, and the long-term benefits of green technology.
