Documented cause
Zolar built a digital platform for residential solar installation in Germany, acting as a marketplace connecting homeowners with certified installers. The company raised over €100M, benefiting from Germany's clean-energy transition. But installer availability bottlenecks, post-pandemic supply chain disruptions for solar panels, and a customer acquisition cost that outpaced installation revenue pushed the company into insolvency in September 2023.
Lesson
“Green-tech marketplace businesses with no installer exclusivity and no panel supply contracts are exposed to simultaneous supply and demand shocks with no buffer.”
