Overall energy and exergy performance of partially covered N-photovoltaic thermal (PVT)-compound parabolic concentrator (CPC) collectors connected in series

In this study; the analysis has been carried for overall thermal gain and equivalent electrical exergy of partially and fully covered N photovoltaic thermal-compound parabolic concentrator connected in series. Here; it is a basically comparative study to find to choose the best system for use for thermal gain and electrical gain. The outlet temperature at N
^th
collector has been derived. The thermal modelling has been done by considering certain assumption. The electrical efficiency of solar cell has been derived. The annual analysis has been taken for location New Delhi; India and clear day type whether condition. The maximum annual overall thermal energy gain has been obtained 1220.03 kWh which is for partially covered N photovoltaic thermal(PVT)-compound parabolic concentrator (CPC) and maximum annual electrical gain has been found 141.76 kWh in fully covered N PVT-CPC collector. The maximum overall exergy has been obtained 133.62 kWh for N PVT-CPC collector.
