HIPERION: Scale-up of hybrid planar micro-tracking solar panels for rooftop compatible CPV

Within the EU-funded project HIPERION, significant progress has been made on the Insolight solar panel: a high-efficiency rooftop compatible micro-CPV device with integrated planar microtracking and diffuse collection via additional low-cost Si solar cells. The IES-UPM and other R&D centers in the consortium have been tasked with characterizing the various generation of this technology. In this work we discuss the evolution of the module design and present the latest results for "Gen1" solar panels showing significant improvement in performance in self-tracking compared to earlier results even in the face of a 5X increase in module area.
