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 x GEN-I: Accelerating the Future of Energy Storage in Southeast Europe
SUNOTEC and GEN-I, d.o.o. have entered into a 5-year partnership to advance two battery energy storage facilities in Bulgaria, totalling 200 MW and 505 MWh, which are set to be operational by the end of March 2026.
Under this agreement, GEN-I will serve as the exclusive asset optimiser and trading partner for two SUNOTEC-developed storage facilities. This cooperation brings together SUNOTEC’s engineering, construction, and project delivery expertise and GEN-I’s advanced 24/7 trading, algorithmic optimisation, and market integration.
“This agreement marks a significant milestone in SUNOTEC’s long-term energy storage strategy,” said Kaloyan Velichkov, Founder and CEO of SUNOTEC. “As we scale our investment portfolio and integrate BESS solutions into our core development, collaborating with experienced and forward-thinking partners like GEN-I is essential. We aim to establish a strong foundation for our IPP strategy while building resilient energy infrastructure 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.

2024 was a year that once again reminded us of the urgency of action. It broke numerous global climate records and marked a pivotal moment in our planet’s history.
Renewable energy stands at the forefront of the global response. We at SUNOTEC believe that this transition to alternative forms of energy must not only be clean and reliable but also affordable and inclusive. It should empower communities, enable equitable access to energy, and drive long-term economic growth.
That’s why Sustainability is woven into everything we do, from how we design and construct, to how we operate and maintain our plants.
🌱 The publication of our Sustainability Report 2024 is a reminder of the tangible impact we can achieve for people, the planet, and our shared resources, one project at a time.
Click below to see the impact our integrated solutions approach to large-scale solar and BESS has, and the importance of embracing cutting-edge technologies, offering reliable operations, maintenance and re-powering services to allow our plants to operate as long and efficiently as possible.

Sustainability is not a chapter in our strategy. It is the foundation of how we build the future.
2024 reminded us why our mission matters more than ever. Global temperatures exceeded pre-industrial levels by more than 1.5°C for the first time. At SUNOTEC, we view this as a call to action, and we are responding with speed, scale, and responsibility.
🌱 In just one year, we installed 2.3 GWp of new solar capacity and added 200 MWh of battery storage to the grid.
🌱 Our projects have avoided over 525,000 tons of CO₂e emissions, which is almost double our own footprint.
🌱 We created 700+ local jobs and welcomed colleagues with humanitarian status into our workforce.
🌱 Beyond energy, we contributed €660,000 to community initiatives and charities.
But numbers only tell part of the story. What makes us proud is how we do it: transforming degraded land into clean energy hubs, designing biodiversity-friendly solar parks, manufacturing steel mounting systems with recycled content, and setting ambitious goals, such as becoming net zero by 2050.
Our journey is far from over, and it is one we want to take with our partners, communities, and peers.
