The overall efficiency increases with increased heat removal, lowering the cell temperature. The current study investigates the effect on heat removal rate using copper nanoparticles dissipated in volume fractions of 2% and 3% with pure water. Using mathematical modeling is constructed from the heat balance equation in different components of the PVT collector. It is found that as the volume concentration increases, the electrical performance is also increased. Average electrical efficiencies are 14.5%, 14.8%, 16.8%, and thermal efficiency are 30.59%, 27.32%, and 21.27% for summer, winter, and monsoon seasons, climatic condition of the city Ujjain of India, respectively.</p></abstract><kwd-group><title>Keywords</title><kwd>Electrical efficiency</kwd><kwd> Nanofluid</kwd><kwd> PVT collector</kwd><kwd> Solar energy</kwd><kwd> Thermal  heat gain</kwd></kwd-group><counts><ref-count count='' /><page-count count='' /></counts></article-meta></front></article>
