“I started with one van and one promise.”
In 1998 I installed my first solar system on my parents’ barn in Kirchzarten. The promise was simple: nothing on your roof that I would not put on my own.
Today 38 people keep it. Every apprentice learns it on day one, and I still climb on every tenth roof myself.
