PVT & Geothermal Probes: Storage Solution for Solar Energy · Commercial Building, Neuweiler, Baden-Württemberg

Project Challenges:

  • Several geothermal probes in a comparatively small space
  • Explicit customer request to regenerate the geothermal probes
  • Maximizing the efficiency of the heat pumps: increasing the annual coefficient of performance

Solution with Sunmaxx PVT:

  • Transfer of excess heat from summer months to geothermal probes
  • Dual use of geothermal probes as a heat source and heat storage
  • Geothermal probe regeneration using PVT, sustainability of geothermal system secured

Also a Great Idea in Combination with Geothermal Energy – PVT for the Regeneration of Geothermal Probes

PVT as competition for geothermal energy? Wrong! Besides monovalent systems and the interaction of PVT and ice storage systems, our hybrid modules can also be perfectly combined with geothermal probes. Our partner, a drilling company from Baden-Württemberg, has recognized the unique interaction between PVT and geothermal energy – the geothermal probes under the company building serve as seasonal storage for excess heat from the summer months, which is transported into the ground using PVT and brine heat pumps.

Geothermal Probe as Sustainable Heat Supplier: Only with PVT Regeneration

Geothermal probes cool down over time. Especially with many probes in a confined space (so-called geothermal probe fields), more heat is extracted from the ground via the brine heat pump than can flow in. Geothermal probes can only be operated and used sustainably through regeneration, for example with the help of solar heat. Our PVT modules generate the energy required for this over the summer months.
