Solar-Log GmbH

In 2004 Jörg Karwath had the initial spark and developed the first Solar-Log TM in his garage, a data logger as a monitoring device for photovoltaic systems. Three years later, in 2007, the start-up company Solar-Log GmbH was founded by Thomas Preuhs and Jörg Karwath. In just a few years, the company expanded worldwide, so that by 2011 the Solar-Log TM hardware family was already being sold in 20 countries. Since 2015, Solar-Log GmbH has been a subsidiary of BKW AG from Switzerland, an international energy and infrastructure company based in Bern. Photovoltaics is becoming more and more important - both nationally and internationally, and the markets are constantly posing new challenges for the Solar-Log TM energy management system. Solar-Log GmbH meets the requirements and offers innovative solutions.
