This study is to evaluate the electrical efficiency and heat gain of the PVT system by implementing a rectangular shape absorber design of size 0.03 × 0.01 m2 and aspect ratio 0.003 using nanofluid TiN/w at volume portion 4% by weight as a coolant with a flow velocity ranging from 2 × 10−4 to 4 × 10−4 m/s for two different cities (Nagpur and Jaisalmer) in India, a numerical model has been established to analyze the PVT collector's electrical efficiency and heat gain by employing an energy balance equation of different components of the PVT system. The numerically evaluated highest daily electrical efficiency and heat gain of PVT systems are 16.18, 15.13% and 308.17 and 338.05 Wh, respectively, for Nagpur and Jaisalmer cities.

This study is to evaluate the electrical efficiency and heat gain of the PVT system by implementing a rectangular shape absorber design of size 0.03 × 0.01 m2 and aspect ratio 0.003 using nanofluid TiN/w at volume portion 4% by weight as a coolant with a flow velocity ranging from 2 × 10−4 to 4 × 10−4 m/s for two different cities (Nagpur and Jaisalmer) in India, a numerical model has been established to analyze the PVT collector's electrical efficiency and heat gain by employing an energy balance equation of different components of the PVT system. The numerically evaluated highest daily electrical efficiency and heat gain of PVT systems are 16.18, 15.13% and 308.17 and 338.05 Wh, respectively, for Nagpur and Jaisalmer cities.
