Abstract
In the present study an investigation was conducted on the temperature distribution effect for several tank capacities (100 L, 120 L, 150 L and 200 L) having two different aspect ratios (H/D) for each capacity. Hot water is supplied to these tanks by a Hybrid PV/T collector of 4 m² illuminating area. The circulation of water within PV cells cools its surface area to solve the problem occurred in PV cells, where each 1°C increase in the surface module 0.45% of the electrical efficiency decrease. A pump circulates water from the bottom of the tank to PV/T collector and then dropped it at the top of the tank in order to maintain thermal stratification. It was obser...
