Today, electric power generated from wind is making a significant contribution to the transition to clean energy. Due to the increasingly larger and more powerful wind turbines, the technology is consistently becoming more advanced. This leads to continued growth worldwide. Professional monitoring is also needed for the production of power from wind energy to ensure that electricity is produced without any problems.

For this reason, the company  Solar-Log GmbH in Berlin was founded. The company develops innovative software solutions for the professional monitoring of wind parks.


Sustainability as a Matter of Principle: Vision Becomes Reality

A large portion of CO2 emissions worldwide come from energy produced from the fossil fuels. CO2 emissions can only be reduced with the increased use of renewable energy. Our products and solutions actively promote the continuous production of energy from renewable sources and the direct consumption of this energy. A clean environment is essential for us! By taking a look at the building of our headquarters in Geislingen-Binsdorf, one realizes that we do not only promote the production of energy from renewable sources: The energy for the building and for our daily work comes from renewable sources.

We use the hidden energy from our ice store system to heat our building. Two heat pumps first extract energy from the water in our storage tanks and then use this energy from the phase change (between liquid water and frozen ice) so that a large ice cube forms in the storage tank at the end of the heating phase. We use this cooling potential during hot summer months to keep the building cool.

Summ Summ

Biodiversity and nature conservation are not just buzzwords for us. As a further measure we have now established a bee colony on our premises in cooperation with an organic beekeeper. Organic beekeeper Matthias and our colleague Dirk take care of the honey producers.
