Who We Are

Johann von Gott Thoma

Johann von Gott Thoma

I made my first products in 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 everyone and nearly every stringer on the market is using it.


Since 2001, I’ve been consulting with solar module startups all over the world. With the start of our online E-course, we are taking the next steps to help even more people become successful producers of solar panels.

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

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