Samenvatting:
A first, non-optimised prototype of a combi-panel was built of a PV-laminateand a sheet-and-tube absorber. The thermal efficiency at zero reduced temperature was found to be 54%, along with 8.5% electrical efficiency. The results of the measurements were used to verify the results of the simulations. It was concluded that the simulations and the measurements corresponded sufficiently well. Then, the simulations were used to find the annual efficiency of a PV/T-system that was used for hot-water production in a Dutch houshold, for which 33% themal and 6.7 electrical efficiency was found. Finally, the simulations were used to quantify the contribution of the various loss terms to the reduction in thermal efficiency of a PV/T-system with respect to a thermal collector.
