JAS Energy SOLutions Team - Teamwork

Teamwork

Interdisciplinary experts working side by side – from the first site assessment through detailed planning all the way to commissioning your system.

  • Construction, energy and engineering
  • Dedicated points of contact
  • Planning and execution from a single source

What drives us

Technical integrity

We never say “good enough” when it isn’t. Roofs that are not structurally sound won’t be fitted with modules. Systems that don’t pay off don’t get sold. We want results we can stand behind.

Energy independence for our clients

Generating your own power instead of buying everything from the grid – that is our promise. We build systems that reduce grid consumption, make electricity costs more predictable and stabilise property value.

Working as equals

Open communication, short decision paths and a dedicated project team for every installation.

Dipl.-Ing. Julian Roth

Managing Director & Founder

As a TU Vienna electrical engineering graduate, I have worked in renewables for over five years. I am driven by developing technical solutions that perform in the long term and contribute to a sustainable energy supply. In my free time I love to play tennis.

Dipl.-Ing. Ali Khreis

Managing Director & Founder

Sustainable energy solutions are, for me, the key element of a future-proof energy supply. PV systems are only the first step. I focus on energy modelling and strategies that make the expansion of renewables plannable, controllable and truly implementable – with the clear aim of measurably advancing the energy transition.

Managing Director & Founder

During my civil engineering studies I became increasingly involved with renewables. Throughout my career I have contributed to numerous construction projects, gaining extensive experience in planning, supervision and execution. I am passionate about sport and actively shaping our built environment. My goal is to make Vienna greener.
