I made my first products for the solar industry more than 20 years ago in 1996. I invented a patent to solder solar cells in a reflow soldering process. The patent is now open for all and nearly every stringer on the market is using this process.


Since 2001 I ​have been consulting for solar module startups all over the world. ​​With the start of our online e-course, we are now taking the next step to help even more people be successful producers of solar panels.

I have been making business plans since 2003. In 2006, together with my father and one investor, I started our own solar module production line in Europe.


I have been a shareholder of this company for more than 10 years. From 2005-2009, I was CEO of this company and was completely involved in all production processes. My goal is to help other entrepreneurs start their own local production in their country.
