Thermal Management Solutions DE Oberboihingen GmbH is investing in a sustainable future. In collaboration with CUBE CONCEPTS, a comprehensive photovoltaic project is being developed at the Oberboihingen site. The goal is to strengthen self-sufficiency with environmentally friendly electricity, significantly reduce CO₂ emissions, and secure long-term competitiveness.
Rooftop solar PV system
The photovoltaic system was officially inaugurated on August 14, 2025, as part of a symbolic ceremony. The ceremony was attended by Managing Director Holger Kiebel, Head of Quality & Environment Lars Petry, Mayor of Oberboihingen Ulrich Spangenberg, Managing Director of Südwestmetall District Group Neckar-Fils Ralph Wurster, and representatives from CUBE CONCEPTS.
A total of 986 solar modules were installed on a roof area of approximately 5,800 m².
Thermal Management Solutions DE Oberboihingen GmbH on their path to climate-neutral production at the Oberboihingen site:
With its roof-mounted photovoltaic system, CUBE CONCEPTS aims to make Thermal Management Solutions DE Oberboihingen GmbH more independent from rising electricity prices. As a world-leading manufacturer of thermostat and oil temperature regulators for the automotive and commercial vehicle industries under the ‚Wahler‘ brand, the company focuses not only on product quality but also on its ecological footprint.
The PV system is the final piece of the puzzle, alongside several avoidance, reduction, and offsetting projects, on the path to climate-neutral production at the Oberboihingen site. The company has already been confirmed by the certification body TCS (Technical Certification Services GmbH) on July 7, 2025, for the successful implementation of CO₂-neutral production. By using green PV electricity, the Oberboihingen plant will continue to be a strong partner for its customers in the future and further expand its competitive advantages.
With this commitment, Thermal Management Solutions DE Oberboihingen GmbH underscores its responsibility for the environment and society, and relies on innovative energy partnerships to ensure the long-term sustainability and efficiency of the site.
Voices on the PV Project
Mayor of Oberboihingen Ulrich Spangenberg is pleased about the CO₂-neutral electricity production on the existing roof areas of the Oberboihingen-based traditional company: „With this extraordinary commitment, Thermal Management Solutions has built what is probably the largest photovoltaic system on an existing building in Oberboihingen. Especially at energy-intensive industrial sites, using roof areas for electricity production for self-consumption and for feeding into the general power grid is an important step to save CO₂ in a sensible and sustainable way.“ He hopes that other companies will follow this example. Ultimately, he is convinced, this will also be an important factor in terms of the necessary resilience to changes in the electricity and energy markets.
Ralph Wurster, Managing Director of the Südwestmetall District Group Neckar-Fils, remarked: „Especially in economically challenging times like these, it is a strong signal when a company not only believes in its location but also specifically invests in its future viability. With this photovoltaic project, Thermal Management Solutions DE Oberboihingen GmbH demonstrates that economic action and sustainable responsibility are not mutually exclusive, but can be purposefully combined. The commitment to the Oberboihingen location and the investment in climate-friendly technologies are exemplary for future-oriented industrial policy in the SME sector – and a clear sign that transformation can also be actively and successfully shaped in an industrial environment.“
