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.

TECNALIA-Facilities for BIPV systems

  • Capabilities, facilities and equipment (SW, characterization devices) to offer services in the field of BIPV systems: optical/mechanical/thermal simulations
  • PV modules & devices characterization
  • indoor and outdoor testing of BIPV modules and BOS, etc.

Technical Info


BIPV-TECNALIA comprises a set of capabilities, facilities and equipment (SW, characterization devices) which allows TECNALIA to offer services in the field of BIPV systems: optical/mechanical/thermal simulations, PV modules & devices characterization, indoor and outdoor testing of BIPV modules and BOS, etc.

TECNALIA’s facilities on BIPV systems allow to design, develop and test any sort of PV product / solution in the frame of “photovoltaic in buildings” systems, for the whole value chain of the BIPV technology, taking advantages of a great compilation of equipment, capabilities and experience. It includes services for both (1) BIPV modules and (2) BOS components, typically power conversion systems (inverters, module level power electronics-MPLE) and energy management systems (EMS, including storage-based solutions). Designs and solutions are then tested at lab level and/or in outdoor conditions, thanks to TECNALIA’s infrastructures in this field (e.g. KUBIK), and for BIPV modules, tests under the new BIPV standards can be offered. In total, 16 researchers work in this field in TECNALIA.
