Experimental Study of Exergy Analysis on Flat Plate Solar Photovoltaic Thermal (PV/T) Hybrid System

Abstract

The objective of present study is to conduct exergy analysis on flat plate solar photovoltaic thermal (PV/T) hybrid system. The solar insolation, current, voltage, inlet and outlet air temperature of the cooling duct, ambient air temperature, and solar panel surface temperature are the major parameters used to calculate the energy and exergy efficiency. An amended electrical efficiency is used to estimate the electrical output and performance of PV/T hybrid system. Further, an enriched equation for the exergy efficiency of a PV/T hybrid system has been used for exergy analysis. Finally, parametric studies have been carried out. An extensive energy and exergy analysis is carried out to calculate the electrical and thermal parameters. The experimental results are in good agreement with the earlier studies. In addition to that, the electrical efficiency, thermal efficiency, electrical thermal efficiency, overall energy efficiency and exergy efficiency of PV/T hybrid system is found to be about 9.78%, 24.22%, 27.17%, 44.84% and 11.23% respectively.

Electrical and thermal efficiency of air-based photovoltaic thermal (PVT) systems: an overview

“…An exergy analysis of flat plate air based PVT system had been conducted by Srimanickam et al [33]. It had been attained that the system had generated 9.78%, 24.22%, 44.84% and 11.23% respectively of electrical, thermal, overall energy efficiency and exergy efficiency.…”

Modelling and Optimization of Photovoltaic Serpentine Type Thermal Solar Collector With Thermal Energy Storage System For Hot Water and Electricity Generation For Single Residential Building

“…Solar energy is typically used to generate heat energy and electric energy using thermal collectors and PV systems. While the use of solar energy has grown, some limitations, such as high installation costs (Fakouriyan et al, 2019;Srimanickam et al, 2015), low energy conversion e ciency (Srimanickam et al, 2017;Srimanickam and Saranya, 2021) and the need for storage systems due to supply and demand curves that differ (S. Thakur et al, 2020) have a negative impact on its use in comparison to other renewable energy sources. An enormous amount of research articles on photovoltaic/thermal (PV/T) technologies have been published in an attempt to resolve the above said barriers (Giwa et al, 2020;Lamnatou et al, 2021;Reji Kumar et al, 2020).…”
