Abstract

Due to resource depletion and environmental pollution, research on renewable energy has been conducted for a few years in various professional communities. Building-Integrated Photovoltaics (BIPV) presents tremendous growth potential for building energy conservation. This paper compares the performance of two kinds of solar PV window in BIPV system: namely crystalline-silicon (c-Si) PV glazing and amorphous-silicon (a-Si) PV glazing. The study employs a typical office floor in Hong Kong as a case study. Based on the laboratory test and simulation results, this study reports the performance of two solar PV glazing systems in terms of the daylighting, thermal, electrical and total energy consumption. The analysis results suggest that the amorphous-silicon PV glazing system presents better-daylighting performance and thermal performance, while crystalline-silicon PV glazing performs better in the electrical part. Besides, the study considers the influence of dimming control being applied regarding energy performance. The study found no significant difference in the annual energy performance of two systems without dimming control, while crystalline-silicon PV glazing saves more energy when dimming control is integrated. The results suggest that the energy-saving performance of BIPV systems might be impacted by the type of solar PV system. The findings would provide an informative reference for BIPV technology applications in Hong Kong.
