Energy performance of partially covered N photovoltaic thermal-compound parabolic concentrator (PVT-CPC) collector for cold climate condition

In the paper, an attempt has taken to analyze the energy of N photovoltaic thermal (PVT)-compound parabolic concentrator (CPC) water collectors connected in series. The analysis has been examined for cold climate condition where high fossil fuels are need to get thermal energy. Two fluids has been considered: (i) water and (ii) air. The comparison has been made with two different fluids on partially covered N photovoltaic thermal-compound parabolic concentrator (PVT-CPC) collector connected in series. Here, the collector of proposed system is partially covered with 25% of PV module. The thermal modelling has been developed with basic energy balance equation of each component of proposed system. The outlet at N^th 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 Srinagar, India. The maximum thermal energy has been found 12.92 kWh and 3.72 kWh per day for fluid: water and air respectively and thermal exergy has been found 1.63 kWh and 0.55 kWh per day with eight number of collector.
