Energy Performance Analysis of A PV/T System Coupled with Domestic Hot Water System

Abstract

Abstract: In this paper, a standalone photovoltaics‐thermal solar panel is modelled using the TRNSYS simulation engine. Based on this, it is explored how such a system can be comprised with thermal and electrical storage components to provide electricity and hot water for a dwelling in a warm location in Europe. Furthermore, it is investigated how by cooling the temperature of the solar cells, the electrical power output and efficiency of the panel is improved. The performance of the system has also been studied and it is investigated by what amount the solar panel is able to convert the solar energy into electricity. Through this, it is discovered that when the temperature of the panel is reduced on average by 20%, the electrical power output is increased by nearly 12%. Moreover, it is demonstrated that the modelled system can provide hot water under different solar radiation conditions and during all seasons of the year.
