A sensitivity study for n similar partly enclosed with photovoltaic thermal flat plate collectors having series connection

Abstract

A sensitivity study for N similar partly enclosed with photovoltaic thermal flat plate collectors with a series connection (N-PVT-FPCs) has been carried out in this research study. The analysis has been done for a typical day of May, wherein data for the ambient conditions of New Delhi (India) has been received from the India metrological department (IMD), Pune, India. In addition, further computational work has been carried out on the MATLAB programme for the daily heat gain of N-PVT-FPCs. One-at-a-time (OAT) methodology has been used for the sensitivity analysis. From the sensitivity analysis, it has been found that the heat gain from the proposed system is more sensitive with respect to the number of collectors (N) followed by inclination angle, mass flow rate (MFR) and packing factor (PF). The sensitivity figure has been found to be 0.08, 0.17, 0.25 and 0.94 for daily heat gain of N-PVT-FPCs with respect to PF, MFR, inclination angle and N, respectively.
