The present study is performed experimentally to determine the performance of a flat-plate solar collector and evacuated tube solar collector with using nanofluid. Three different nanoparticles are applied during the presented work WO3, CeO2, and Cu. These nanoparticles are used with different volume concentration. All the experiments are done under different mass flux values of the fluid. All nanofluids are prepared with new methods. The stability check of nanofluids is performed with the help of zeta potential measurements apparatus. The thermal conductivity of nanofluids is measured with transient plate source methods. The effect of using nanofluid on the area of the collectors is calculated. Based on the presented work, the flat plate solar collector maximum efficiency increases up to 13.48% compared with pure water when WO3/water is investigated. The stable CeO2/water nanofluid enhances the performance of the flat and plate solar collector with a maximum value of 10.74%. The evacuated tube solar collector is tested with the CeO2/water and WO3/water nanofluid and the results show that the collector thermo-optical efficiency increases up to 34% and 19.3%, respectively. The performance of the solar collector with copper/water nanofluid is shown an increase in the thermo-optical efficiency to 0.83. The needed area of the collector can be decreased with 34% for the application of the copper/water nanofluid. The present work shows that 312 kg of CO2 could be saved per year when copper nanoparticles are used in the collector. Moreover, the copper nanoparticles reduce the payback period up to 30.8%.
