Energy analysis of partially covered number (N) of photovoltaic thermal-compound parabolic concentrator collectors connected in series at constant collection temperature mode

Abstract

In present study, study has taken attempt to show the analysis of N-number of photovoltaic thermal (PVT)-compound parabolic concentrator (CPC) water collectors connected in series water collectors under constant collection temperature mode for the point of user's demand unlike constant flow rate mode. The performance has been examined for thermal energy, thermal exergy and overall thermal energy of partially covered (N) number of Photovoltaic thermal-compound parabolic concentrator collectors connected in series has been analyzed. Here, the collector of present system is partially covered with 50% of PV module. The thermal modelling has been developed with basic energy balance equation of each component of proposed system. The outlet at Nth of partially covered Photovoltaic thermal (PVT)-compound parabolic concentrator (CPC) collectors has been obtained. The expression of analytical temperature dependent electrical efficiency of proposed system has been derived. The analysis has been carried out for clear day condition in month of January at New Delhi, India. The maximum thermal energy has been found 18.14 kWh per day and electrical energy has been found 1.30 kWh per day with constant outlet collection temperature at 67 °C.
