The current work investigates experimental characteristics of the
Photovoltaic Thermal system integrated with CuO-Water spiral flow heat
exchanger and compared with non-cooled PV module. The work describes detailed
procedure of Nanoparticles (NPs) preparation, SEM characterizations and heat
extraction characteristics of Nanofluid (NFs) in PVT application. The heat
exchanger was pasted at the back of polycrystalline PV module to form PVT
system to examine cooling ability, power generation, thermal-electrical yield
and overall efficiency at a different volume concentration of CuO NPs at
steady mass flow rate of 0.08 kg/sec. From the experiments, it was concluded
that the CuO-Water NFs assisted to lessen surface temperature of PV module by
extracting heat that enhanced electrical efficiency by an average of 3.53%.
It was also seen that electrical and thermal performance was improved at
higher volume concentration and overall efficiency of 30.77% and 36.59 % were
obtained at 0.01% and 0.03% of volume concentration.
