uma Schreibgeräte Ullmann GmbH from Fischerbach in the Black Forest is investing in self-sufficient electricity production. “Late last year we installed a photovoltaic system on our roofs, and now, in April 2023, it is fully operational. This investment marks a further considerable improvement in our ecological footprint. It means we’re not just ‘writing’ sustainably, we’re living sustainably too,” reports Managing Director Alexander Ullmann.

The extensive system is mounted on all 3 site buildings, one to the west, one to the south and one to the east. With this, uma attains a self-sufficiency rate of 40%, which is considerably above the average for conventional systems. At approx. 450 kW/peak, it is one of the larger systems in the Kinzig Valley / Black Forest. The whole of production, the offices and the warehouse have a self-sufficient electricity source immediately at their disposal. Electricity not used on site – anticipated to be 240 MWh annually – will be fed into the public grid. “By doing this, we’re not only taking care of green electricity at uma, but also contributing to supplying the region sustainably,” Ullmann emphasises.
