Project Challenges:
- Decarbonization of a production plant of automotive supplier MAHLE
- High energy demand for heating and process heat
- High investment costs for geothermal energy
- Comparatively few suitable roof areas available
Solution with Sunmaxx PVT:
- Switch from gas heating to renewable system
- Use of low-temperature heat with PVT and brine heat pump
- PVT for ground probe regeneration: reduction in drilling meters with significant cost savings
- Design of the PVT system as a rooftop and ground-mounted system
MAHLE Leads the Way by Decarbonizing its First Plant in Vaihingen-Enz PVT for Heating and Process Heat Generation and Power Supply
Automotive supplier MAHLE is setting a good example: MAHLE is decarbonizing its production site in Vaihingen-Enz with 1,000 PVT modules from Sunmaxx. From the end of 2025, the heat and electricity supply will be mostly autonomous and climate-neutral. The switch saves the plant 900 tons of CO₂ annually, while at the same time reducing project costs with PVT from an initial €10 million to less than €3 million.

One System, Two Technologies – Maximum Space Utilization with Sunmaxx PVT
Since there was only limited roof space available at the site, the system was divided: one part operates as a flat roof system, while the other was installed on an adjacent open space. Directly below, geothermal probes store the heat generated seasonally so that it is available again in winter. This clever combination makes the site’s energy supply highly efficient and predictable all year round. MAHLE is thus demonstrating how industrial decarbonization is already economically and technically feasible today.
