ANALYSIS OF A PHOTOVOLTAIC/THERMAL SOLAR COLLECTOR FOR BUILDING INTEGRATION

The idea of combining photovoltaic and solar thermal collectors (PVT collectors) to provide electrical and heat energy is not new, however it is an area t hat has received only limited attention. With concern growing over energy sources and their usage, PVTs have become a focus point of interest in the field of solar energy research. Although PVTs a re not as prevalent as solar thermal systems, the integration of photovoltaic and solar thermal colle ctors into the walls or roofing structure of a building could provide greater opportunity for the use of renewable solar energy technologies in domestic, commercial and industrial applications. A s such, the design of a novel building integrated photovoltaic/thermal (BIPVT) solar collector is the oretically analysed through the use of a modified Hottel-Whillier model. The thermal efficiency under a range of conditions was subsequently determined and results showing how key design parameters influence the performance of the BIPVT system are presented.
