Abstract (EN): This paper presents the results obtained from laboratory testing of four liquid flat plate collectors. The collectors tested include a wavy fin collector, two flat plate heat pipe collectors, and a clip fin solar collector. The clip fin solar collector was tested, so as to compare this simple and inexpensive type of collector against the more costly wavy fin collector and the flat plate heat pipe collector. Using a similar basis of comparison, efficiency values have been formulated in order to compare the performance of the solar collectors. The experimental results show the clip fin solar collector to be promising, with experimental efficiencies approaching 86 per cent.

The collectors tested include a wavy fin collector, two flat plate heat pipe collectors, and a clip fin solar collector. The clip fin solar collector was tested, so as to compare this simple and inexpensive type of collector against the more costly wavy fin collector and the flat plate heat pipe collector. Using a similar basis of comparison, efficiency values have been formulated in order to compare the performance of the solar collectors. The experimental results show the clip fin solar collector to be promising, with experimental efficiencies approaching 86 per cent.Four types of liquid flat plate solar collectors were tested for use with a combined heat and power production system. The performance comparison was based on efficiency values for a wavy fin collector, two flat plate heat pipe collectors, and a clip fin device. The relatively inexpensive clip fin collector demonstrated promising performance, with experimental efficiencies approaching 86%. Indicative efficiencies for the wavy fin unit were estimated at 60%, and values for the two heat pipe collectors were in the 24-30% range.
