Energy transition "Made in Sonthofen": BHS bets on massive photovoltaic power.

September 14, 2026

BHS-Sonthofen is taking another concrete step toward sustainable and energy-efficient production. In collaboration with regional partner Elektro Uhlemayr GmbH & Co. KG, a pioneering large-scale photovoltaic system has been installed at the Sonthofen site.

As a technology company focused on industrial performance and innovation, BHS-Sonthofen is taking responsibility for a more sustainable energy supply at its own facility. The new photovoltaic system utilizes existing roof space to generate and consume the largest possible share of required electricity directly on-site.

220.8 kWp photovoltaic capacity for the Sonthofen site

A total of 480 Heckert Solar modules are being installed across a roof area of approximately 959 m². The roof’s east-west orientation and 15° pitch allow for a broad distribution of power generation throughout the day. The system features a modern inverter setup utilizing SMA Sunny Tripower 125-70 and Sunny Tripower X 60 units. The projected annual yield is approximately 209,259 kWh. Of this, 84.2%—or 176,168 kWh—is intended for direct on-site use in the company's own processes.

In doing so, the photovoltaic system not only contributes to the use of renewable energy but also supports an efficient and cost-effective energy supply for the site.

Another step toward a more sustainable site

With the new photovoltaic system, BHS-Sonthofen is moving toward a more independent and renewable energy supply at its Sonthofen location. The high projected rate of self-consumption demonstrates that a large portion of the generated energy can be utilized immediately within operational processes.

The project thus combines technological capability, regional collaboration, and concrete measures for greater sustainability.

Special thanks go to Elektro Uhlemayr GmbH & Co. KG for planning and implementing the project!

The energy transition begins locally—and that is exactly where BHS-Sonthofen is taking action.
