This paper reports an experimental investigation on the performance evaluation of a linear solar collector using a hybrid nanofluid of CuO and TiO2. The scanning electron microscope was employed to study the morphology of the nanomaterials. A linear fresnel lens was used to concentrate solar energy on the required length of the glass tube. The nanofluid was made to flow through the glass tube and absorb the solar energy. Transmittance spectrum of samples indicated optimum properties for 0.20% volume concentration of CuO and 0.25% volume concentration of TiO2 based on which the hybrid nanofluid was prepared. The results indicated superior thermal and optical properties for the hybrid nanofluid. The absorbance of the nanofluid was found to increase with the concentration of CuO nanoparticles. Temperature profile indicated that the hybrid nanofluid could absorb more heat then water and the base fluid even at lower concentrations. Further, the photo-thermal conversion rate of the samples was found to increase with the absorptivity of the nanofluid.
