About us

Greencells doesn’t just build solar plants — we help shape Europe’s energy future. With conviction, responsibility, and strong teams.

With more than 180 completed projects and over 3.3 GWp of installed capacity, we are one of Europe’s leading EPC and O&M providers for utility-scale solar power. We provide engineering, construction and technical O&M services for grid-connected PV plants in Germany, the Netherlands, the United Kingdom, Ireland, Romania and Hungary – efficiently, reliably, and always looking ahead.

What drives us:
We build clean energy solutions for a better tomorrow.

It’s not just a line – it’s what we stand for.

And how we work reflects that: We take ownership. We listen, think ahead and act with purpose. We stay pragmatic when things get complex. And we’ve got each other’s backs when it matters. For us, quality isn’t a commitment – it’s a mindset.

Whether you manage projects, design systems, balance books or shape communications – you’ll find freedom here, not rigid structures. Your ideas matter. Your initiative is welcome. And your impact is tangible – in results, in teams, in the energy transition.

At Greencells, you’ll work in intercultural, interdisciplinary teams – with flat hierarchies, real ownership and the chance to make your mark. Flexible working models, mutual trust and opportunities to grow are just as much a part of our culture as the shared ambition to move forward – professionally and personally.

If that sounds like the kind of place you’re looking for – we’d love to get to know you.
