About us

Our company with the place of business in Dresden / Saxony was founded in 1990. Climatic changes and rising energy costs were the reasons for us to look rather closely at renewable energies and the use of them through various conversion techniques.

In 2002 therefore we founded the independent Engineering Consultancy for Renewable Energy Systems (Ingenieurbüro für Regenerative Energiesysteme Dipl.-Ing. (FH) Joachim Siebert).

With the market growth and the increasing specialization in 2010 we decided to split the responsibilities and founded the second company Solarsysteme Sachsen GmbH. The consultancy for renewable energy systems (Ingenieurbüro für Regenerative Energiesysteme Dipl.-Ing. (FH) Joachim Siebert) is still responsible for planning , research and development. Solarsysteme Sachsen GmbH supports the project management including assembling and installation of the proposed systems.

An high specialisation of our staff and a vast network of innovative and qualified partners guarantee optimum solutions with the best results.

We advise independently, neutrally and customer-focused, regardless of manufacturer and products. We are there for you...from the first steps to the pre-stage of the economic characteristics, the handover of the designed project, the installation of the systems and the service & maintenance in the future. The best quality for your needs is our main focus.
