Experiments on Aluminum-Copper Alloys Properties as Solar Absorbers

In this paper, selecting absorber materials for solar collectors is experimentally investigated. Copper and aluminum alloys were cast at four different percentages of each, then their grain structure was examined and comprehensive solar tests were conducted to measure the heat capacity of each alloy and compare that with the available solar irradiance available at the test site at the Hashemite University in Zarqa, Jordan.
