A new concept of biresin hybrid solar tile (HWST) is specifically designed to be used in environments where constraints related to the available surfaces are numerous and sometimes are not entirely overcome by the solutions available on the market, while the energy needs are twofold (thermal and electrical). A dedicated mold provides tailored channels to create  lower and upper shells with a sealing system.
It is also comprised of special systems for detaching the hybrid tile after laying. Moreover, two of the four side walls within which the tile is to be laid are removable in order to guarantee perfect modularity during production. In  comparison to conventional selflocking tiles, the HWST neither require any additional skill for laying, nor its thickness differs.


  • 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.
