The technological feasibility of the PVT4EU technologies will be extensively studied with a strong methodological structure through five phases within the project: Design and Development, Modeling, Prototyping and Testing, Integration, and Impact Evaluation. PVT4EU generates impact in a multitude of areas and sectors. It can be grouped into 5 different main impact groups relating to technological, economic, environmental, and societal impacts:

SolarPeak Collector (PVT-SP)

Version 1.0

PVT-SP V1

SolarPeak has developed a novel heat recovery media (HRM) for HVAC systems, featuring a design that creates zigzag flow to enhance heat transfer efficiency. Unlike conventional parallel tube designs in PVT collectors, this HRM promises better performance and potential adaptation for retrofitting PV panels into innovative PVT collectors with further improvements.

  • Outer dimensions (L x W x H): 1661 x 551×5 mm
  • Material: Polymer
  • Heat loss coefficient: 19.282 W/m2·K
  • Optical Efficiency (Thermal): 48.57%

Version 2.0​

pvt4eu

PVT-SP V2 is a lightweight polymer thermal absorber with increased surface coverage and optimised flow geometry for improved heat transfer. Designed for low-temperature heat recovery, it can retrofit existing PV modules or be integrated into new PVT systems. Its lightweight design makes it easy to handle and install on residential and small commercial rooftops.

  • Outer dimensions (L x W x H): 1465 x 920×8 mm
  • Material: Polymer
  • Heat loss coefficient: 23.36 W/m2·K
  • Optical Efficiency (Thermal): 50%

Solarus Collector (PVT-MG)

Version 1.0

v1
The Double MaReCo (DM) is a symmetric CPC reflector geometry that is specifically designed for PVT collectors to increase the annual output at all latitudes. The bifacial PVT absorber has eight elliptical channels to increase the heat transfer between the aluminum receiver core and the HTF, increasing in this way the HTF temperature and thereby enhancing the electrical efficiency. Figure demonstrates the current version of the DM collector. Further improvements can be made to this collector to increase the thermal output and electrical efficiency.
  • Outer dimensions (L x W x H): 2310 x 1054 x 128 mm
  • Heat loss coefficient: 19.282 W/m2·K
  • No of cells: 76
  • PV Cell type: Silicon mSi
  • Optical efficiency (n0): 53.76%
  • Optical efficiency (n0): 20.1%
  • Peak electric power: 59,66 W
  • No of diodes: 4

Version 2.0

pvt mg v2

PVT-MG V2 is a low-concentration PVT collector using Double MaReCo CPC reflectors to achieve higher operating temperatures and improve heat transfer. Its redesigned PV module and selectively coated rear surface enhance thermal performance while simplifying the electrical design, making it suitable for new installations requiring electricity and higher-temperature heat, such as commercial buildings, district heating, and industrial applications.

  • Outer dimensions (L x W x H):2310 x 1054 x 128 mm
  • Heat loss coefficient: 3.719 W/m2 K
