LNEG Advances Photovoltaic-Thermal Innovation with PVT4EU

The National Laboratory of Energy and Geology (LNEG), PT,  a dedicated ESEIA member, is actively contributing to the development of next-generation photovoltaic-thermal (PVT) collectors through its participation in the PVT4EU project. This CETPartnership-funded initiative brings together six partners from Sweden, Denmark, and Portugal to create efficient and cost-effective PVT solutions for residential heating and cooling and low to medium-temperature industrial processes (20℃-140℃).

Key Developments in PVT4EU:

  • Performance Analysis: Theoretical assessment of the first version of two innovative PVT collectors, Solarpeak PVT (PVT-SP) and MG-Solarus (PVT-SOL).
  • Experimental Testing: Characterization of these prototypes in northern climates, currently under development at DTU – Technical University of Denmark.
  • Environmental Impact Evaluation: Life Cycle Assessment (LCA) to determine sustainability benefits.
  • International Collaboration: Participation in the IEA SHC Task 73 Kick-off meeting in Berlin (February 2025), reinforcing global engagement in solar energy advancements.

Impact and Future Prospects

The PVT4EU project aims to integrate PVT collectors with other renewable heat sources, such as heat pumps, using efficient thermal energy storage for both industrial and residential applications. The advanced PVT technology will:

  • Increase thermal and electrical energy output per unit area
  • Reduce the levelized cost of energy
  • Enable higher operating temperatures for broader applications

By enhancing energy efficiency and decarbonization in both residential and medium-low temperature industrial sectors, PVT4EU supports the transition to a more sustainable energy future.
