Performance Analysis of Double Glass Water Based Photovoltaic/Thermal System

In order to improve the photovoltaic (PV) system efficiency and to get a high yield per unit area, much research has been done in the field of hybrid photovoltaic thermal (PV/T) system. This system co-generates both heat and electricity with better yield compare to independent photovoltaic and solar thermal systems. The present study experimentally analyzes the performance of an in-house developed double glass water based PV/T system under the climatic conditions of Surat, India (21.1702° N, 72.8311° E). Under the tested condition, the average value of the electrical efficiency of the system was observed to be 13.8% while thermal efficiency was found to be 66%. Besides, it was observed that the present system was capable to support hot water requirement of the domestic sector with an average overall efficiency of 80%.
