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 Solare Datensysteme GmbH (SDS) was founded by Thomas Preuhs and Jörg Karwath. Within a few short years, the company established itself as a global leader and by 2011 the Solar-Log™ product range was being sold in 20 countries.
Solar-Log® first entered the U.S. market in 2010 under the newly founded subsidiary, Solar Data Systems, Inc (SDSI). Since then the product line has increased to include the Solar-Log 350, 360, and 370, made for the U.S.A., in the U.S.A.
In 2014, Dr. Frank Schlichting was added to the management team as the CEO. Since then, in addition to the ongoing technical developments, there has been a strong focus on expanding in the North American, Chinese and Indian markets. Since 2015, SDS is a subsidiary of BKW AG (Bern, Switzerland) – a global company for energy and infrastructure.
Solar power is becoming an increasingly popular energy resource both nation-wide and in international markets. New challenges and every-changing market demands continue to drive the Solar-Log® innovation to meet these requirements successfully and efficiently.
