Presented at: ISES Solar World Congress, Jerusalem, Israel, 4-9 juli 1999.
Abstract:
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.
