description The efficiency of a flat plate solar collector using water based CuO nanofluid as a working fluid is analyzed theoretically.

The use of the CuO-water nanofluid as a working fluid could improve the efficiency of flat plate solar collector up to 5% compared with water as a working fluid under the same ambient, radiant and operating conditions.
