KOSTAL Solar Electric

Smart connections. From tradition. Our experience for our customers.

KOSTAL Solar Electric - Quality and innovation. Smart combined

KOSTAL Solar Electric was founded in 2006 as a separate branch of the KOSTAL Group and since then has stood for smart power generation and use. We're continuously developing innovative solutions for the energy of the future so that our customers can use ecological and clean energy - right from their own roof!

So that we can offer our customers the best possible KOSTAL service, we work closely with partners from various sectors, such as the Smart Home sector. Because quality is just as important to us as customer satisfaction, KOSTAL Solar Electric carries out its development and production work in Germany to be able to guarantee the highest quality standards. We have over 100 years of experience as an automotive supplier: another of our plus points.

To ensure that our customers and partners feel safe and familiar with installing and setting up our products, we offer free product training courses from KOSTAL Solar Electric at various locations in Germany, Italy, Spain and France.

KOSTAL in Hagen houses the German headquarters of our parent company KOSTAL Industrie Elektrik, while KOSTAL Solar Electric has established its German headquarters in Freiburg im Breisgau. We've been successful since we were founded in 1912 and are doing our best to continue impressing people in the future with our usual KOSTAL levels of quality.
