At SUNOTEC, we offer expertly integrated solar solutions, activated international expertise, and a lived commitment to resource efficiency and business reliability to all our partners.
YOUR JOURNEY TO SOLAR BRILLIANCE BEGINS EVERYWHERE
Discover how we lead the way in pioneering solar solutions, setting new standards for a sustainable and energy-efficient future, with our new integrated solar solution approach.
The year 2023 marks the first ownership of Bulgarian plants as well as the construction of the largest EPC project with 124 MWp in the Verila mountain range.
By 2027, a pipeline worth 1.3 GWp will be installed. The solar parks will be operated by SECURSUN, the joint venture between German developer securenergy
and SUNOTEC.
Since joining the Danish market in 2017, we have constructed projects worth over 2.8 GWp. This makes Denmark SUNOTECs largest market overall.
As one of our first country markets, France now marks our second-largest market with 840 MWp being installed since 2017.
The year 2024 sees us evolving from a construction partner into a turnkey service provider. Over the past year, more than 200 MWp capacity was installed.
This market emerged in 2023, with two projects totalling an installed capacity of 174 MWp.
Our second EPC project has just been confirmed here.
We are expanding our horizon to West Africa, taking on the role of turnkey provider. With 66 MWp, this plant will be the largest in the country.

🏆 SUNOTEC Wins “Building of the Year”
SUNOTEC’s new administrative and logistics complex in the Stochna Gara area has been awarded “Building of the Year” in the Office Building category, recognising excellence in architecture, sustainability, and urban development.
More than a building, the project demonstrates how thoughtful, sustainable design can drive the regeneration of industrial urban areas. Strategically located in a central industrial zone, the complex initiates the long-term transformation of the Stochna Gara district into a modern, integrated urban hub where business, logistics, and community coexist.
The complex is not merely an administrative building, but a multifunctional business space designed to be the home of SUNOTEC’s culture, vision, and energy.
The project was realised through close collaboration with key partners:
▪ Irkon and Partners Ltd. – architectural design
▪ Barrage Group Ltd. – general contractor
A strong example of how vision, partnership, and responsibility come together to shape the future of work and cities.

A new chapter begins for SUNOTEC as we open the doors to our new home, built to inspire our people, empower our growth, and reflect the sustainable future we are creating together. 🌱
This multifunctional business building is the new, thoughtfully designed home for our teams, with smart architecture, daylight-rich spaces and modern amenities that support wellbeing, focus and collaboration. Every detail reflects SUNOTEC’s ambition to grow sustainably and responsibly while providing a best-in-class environment for our colleagues.
By bringing key functions together under one roof, the new HQ becomes a strategic hub for coordinating across markets and disciplines, strengthening how we plan, build, and operate large-scale solar projects worldwide. 🌍
“A place that strategically unites SUNOTEC teams, creating conditions for effective communication, productive collaboration and a sense of belonging.”
— Ivan Prodanov, Managing Director of SUNOTEC Property and SUNOTEC Machinery.
This new home is a clear statement: SUNOTEC continues to invest boldly in the future of renewable energy, and in the people who make it possible.

Europe’s energy transition is entering its next chapter. Storage will define it. SUNOTEC is already building it.
🔋 As renewable capacity surges, the need for large-scale, intelligent BESS solutions is accelerating to transform solar from a weather-dependent resource into reliable, dispatchable power to stabilise grids, minimise curtailment, and create new long-term value for investors.
Instead of just participating in this shift, SUNOTEC is engineering it.
Through strategic collaborations, cross-market agreements, and the rollout of hybrid and standalone storage assets, the company demonstrates what true integration looks like.
✔ uniting PV, BESS, and substation infrastructure into high-performance energy systems for accelerated deployment
✔ intelligent EMS/SCADA architecture
✔ assets engineered to remain future-ready in evolving market landscapes
✔ dedicated O&M built for the complexity of modern BESS
Today, SUNOTEC is the largest developer and operator of BESS in Bulgaria, powered by a growing pipeline and a fully integrated services portfolio covering engineering, construction, manufacturing and long-term O&M.

What does sustainability look like when it goes beyond clean energy?
In a new interview with SeeNext, our Head of Sustainability Dimitar Dimitrov shares how SUNOTEC is evolving from a solar EPC into a fully integrated energy partner, shaping not only renewable production, but also circularity, biodiversity, and community impact.
With Bulgaria’s renewable expansion now market-driven and battery storage demand accelerating, the clean-energy transition is entering a mature, self-sustaining phase. And SUNOTEC is helping drive that momentum.
This interview captures an important moment for SUNOTEC and for the broader decarbonisation journey in Bulgaria and across Europe.

When technology meets purpose, powerful things happen.
At SUNOTEC, we believe sustainability goes beyond building solar power plants. It is about creating lasting change for people and the planet.
That is why, through the SUNOTEC Foundation, we invest in projects that strengthen the communities where we live and work, supporting initiatives in education, healthcare, culture, sports, environmental protection, and entrepreneurship.
We are taking the next step in our mission to make clean energy accessible through a new partnership with the Sopowerful Foundation, an organisation dedicated to bringing clean, reliable solar energy to schools, hospitals, and vital institutions in underserved regions across Malawi, Tanzania, and beyond.
In less than six years, Sopowerful has:
☀️ Implemented 43 solar projects
☀️ Installed 523 kWp of solar capacity and 1,023 kWh of battery storage
☀️ Driven a 28% rise in school exam pass rates
☀️ Impacted 350,000+ people
“Sustainability is about more than technology; it’s about people,” said Bernhard Suchland, CEO of SUNOTEC. “Working together with Sopowerful allows us to extend the benefits of solar power to communities where access remains limited and where energy can change lives.”
Through this partnership, we are turning sunlight into opportunity and helping build self-sustaining futures.
