Solar-Log™ Company

From a Start-up to the Market Leader

The Solar-Log™ Success Story

In 2004, Jörg Karwath had the initial idea and started developing the first Solar-Log™ in his garage – a data logger to monitor photovoltaic plants. Three years later in 2007, the start-up company Solar-Log GmbH was founded by Thomas Preuhs and Jörg Karwath. Within a few year, the company established itself global presence and by 2011 the Solar-Log™ product range was already being sold in 20 countries.

Since 2015, Solar-Log GmbH is a subsidiary of BKW AG (Bern, Switzerland) – a global company for energy and infrastructure.

Photovoltaic is becoming more and more important as an energy source – both national and international markets constantly present new challenges to the Solar-Log™ energy management system. Solar-Log GmbH meets these challenges by offering a wide range of innovative solutions.
