Sensitivity analysis of a hybrid photovoltaic thermal solar collector

In the present paper, a hybrid photovoltaic thermal (PVT) solar collector is considered. Due to the high complexity and non-linearity of the equations, investigation of the effect of each parameter on the performance of the system is an important task. In this work, the effects of four types of effective parameters including the climate conditions, the mass flow rate of the coolant water, the inlet water temperature and geometric variables are investigated. For investigating the effect of climate conditions on the PVT system, three cities in Iran with different climates including Tehran, Hamedan and Kerman are considered and the performance of the system during sunny hours in each city is presented. The considered geometric variables include PVT thickness, tube spacing and collector´s width. Results are shown by several graphs and discussed extensively.
