The panels had operated for 13 years on the roof of a toothbrush factory in the Black Forest before being dismantled. According to organizer BalkonSolar e.V., roughly 5% of the panels showed defects, while the remainder were suitable for immediate reuse. More than 500 citizens, alongside local organizations and public representatives, assembled 300 plug-in PV systems, each pairing two used modules with a Hoymiles microinverter and cabling.
