The IES provided the optical design and helped to select component suppliers. The scope of the project is to provide a state-of-the-art system with minimal technical risk: i.e. a well-executed rather than novel system that leveraged the capabilities of the current CPV supplier ecosystem. Early on, a choice was made to use all-glass optics: a silicone-on-glass primary lens combined with a molded glass secondary optical element (SOE) as the choice that would combine high performance and reliability. As recent work has shown, when designing concentrator systems with SOG lens their high sensitivity to temperature must be taken into account, and it is shown how an appropriate SOE can reduce this sensitivity. In this paper, we discuss best practices for implementing concentrator systems using SOG primaries and DTIRC SOEs, and show how a range of characterization techniques may be used to optimize them, including the study of their performance sensitivity to focal distance and temperature. We discuss early performance results for the system and show how the final system shows reduced thermal and spectral sensitivity compared to other systems. date: 2012 date_type: published id_number: 10.4229/27thEUPVSEC2012-1AV.3.11 full_text_status: public pres_type: paper pagerange: 194-198 event_title: 27th European Photovoltaic Solar Energy Conference and Exhibition event_location: Frankfurt, Germany event_dates: 24/09/2012 - 28/09/2012 event_type: other institution: Ies department: otro refereed: TRUE book_title: Proceedings of 27th European Photovoltaic Solar Energy Conference and Exhibition rights: by-nc-nd citation: Askins, Stephen and Victoria Pérez, Marta and Herrero Martin, Rebeca and Domínguez Domínguez, César and Anton Hernandez, Ignacio and Sala Pano, Gabriel and Coutinho, Andre and Amador, Jose Carlos (2012).
