CHEETAH knowledge Exchange Portal is an integral part of CHEETAH project web site powered and developed by DTE unit of ENEA ©2014 - 2018 with support of all CHEETAH Partners. Starting from early 2018, CHEETAH KEP moved its first steps to became EERA Knowledge Exchange Platform for PV Technology (KEPT-PV). A new name for the previous platform characterizing our will to serve better and more efficiently in Knowledge Exchange a wider European and International PV RTD community.

Technical Info



The solar energy Unit UES of LNEG is involved in Solar Thermal, Solar Photovoltaic, Thermal Storage. Solar Energy Laboratory(LES) is an accredited Laboratory since 1993, by IPAC according to NP EN ISO/IEC 17025:2005. It can perform tests on solar thermal collectors and other solar components.

The  PV  unit of UES-LNEG is involved in Technological development of photovoltaic systems such as Organic solar cells (OPV) and Inorganic solar (CZTS-based) cells for new generation solar units, new multifunction modules (hybrid PV/T modules), modelling and monitoring of photovoltaic systems and their components and evaluation of power plants performance with and without concentrated photovoltaic (CPV)

PV Laboratory (PV Lab) is also included in the Lab for Renewable energies grid integration. PV Lab is also part of the national Nearly Zero Energy Buildings Infrastructure (nZEB Lab).

  • PV systems integrated in Solar XXI Building including a 12 kW PV facade a 6 kW
  • amorphous silicon car shading structure and a 10 kW CIS car shading structure, all systems completely monitored.
  • A PV/T trigeneration system providing Electricity, DHW, and heat and cooling for a residential load profile.
  • An hybrid PV/Wind stand alone system with 1.3 kW.
  • A Chemical Lab for conversion technologies.
  • Several equipment for PV Cells development.
  • Materials characterization through a SEM device and other materials characterization equipment.
