Problems in the solar industry: Upstarts Enpal and 1Komma5° are also affected. Enpal, a Berlin company that primarily rents out solar systems, more than doubled its sales to 900 million euros in 2023.

The situation is similar at the competing company 1KOMMA5°. Recently there was a conflict between start-ups and the industry association. Tariffs on Chinese products would directly affect the profits of the Berlin start-up - although it can switch quickly if necessary.
