A new concept of bi-resin hybrid solar tile (HWST) is specifically designed to be used in environments where constraints related to the available surface are numerous, while the energy needs are twofold (thermal and electrical). It is comprised of special systems for detaching hybrid tile after laying. Moreover, two of the four walls within which the tile is to be laid are removable in order to guarantee perfect modularity during production. The HWST neither require any addionali skills for laying in comparison to conventional tiles.



  • maximizes energy production 
  • eliminates all the functional and technical constraints 
  • facilitates laying, cleaning and maintenance of the tiles
  • when laid on the ground, allows handy transformation  of existing flooring


  • boating
  • campervans
  • industrial floors
  • terraces and plain roofs

Il gruppo di ricerca Fabbri-Greppi-Proli è stato selezionato a presentare la tecnologia brevettata in occasione dello Start Up Ecosystem Day che si è svolto il 20 Ottobre 2017 presso la Bologna Business School.
