SUNTHINK - DEVELOPMENT OF A NOVEL SOLAR ACTIVE SUNSHADING SYSTEM WITH THIN FILM PV CELLS

摘要

SunThink is a novel photovoltaic system, integrating thin film solar cells in conventional sunscreen louvers (Venetian blinds). Multifunctional use of PV system and sun screen makes facade integrated PV economically feasible as an installation system and a one axis-tracking are already implemented, additionally increasing solar energy yield. Compared to conventional facade integrated PV, more than 50% solar energy surplus can be expected. Two south-oriented prototypes were built up in order to study energetic and thermal operation data. The energetic yield strongly is limited to the self-shading behavior of the horizontal louvers. As major research topics of the study, thermal behavior, the economically optimal PV area on each louver as well as the optimal tracking strategy will be discussed. Measurement data were used to validate a simulation model based on the platform INSEL.
