Abstract

The combination of a solar thermal and photovoltaic system is called photovoltaic thermal system (PVT). The PVT system with and without -absorber has been intended to harvest both hot air and electricity. The hot air that is produced is used in the cooling process of the photovoltaic panel and then to improve the efficiency of the photovoltaic panel. The experimental investigation was conducted at the mass flow rate from 0.0069 kg/s to 0.0491 kg/s and solar radiation of 522 W/m2 and 820 W/m2 in the National University of Malaysia. The using -absorber collector increases exergy and exergy efficiency of PVT system. The improvement potential comparatively upsurges with cumulative the mass flow rate.

Abstract

The solution of the environmental problems because of fuel fossil is to use new and renewable energy. There are many studies about energy analysis of solar collector with v-groove but exergy analysis of photovoltaic thermal system with v-groove is still less especially by theoretical study. Photovoltaic thermal with v-groove collector has been conducted the exergy analysis by theoretical assessment. The matrix inversion methods were used to analyze the energy balance equation. The theoretical assessment was conducted under the solar intensity of 385 W/m2, 575 W/m2, and 875 W/m2 and mass flow rate between 0.01 and 0.05 kg/s. The maximum exergy efficiency and exergy of PVT system with v-groove collector were 17.80% and 86.32 Watt at the solar intensity of 875 W/m2.
