Analysis of solar PV potential for roofs and faades in high dense residential urban scenario of Singapore

Abstract

This paper aims to understand the potential of solar photovoltaics (PV) on building's roof and faades in the dense residential neighborhoods of Singapore. The physical urban morphological parameters such as height, built form, distance between the buildings, orientation, plot ratio, building volume ratio and site coverage have impacts on the solar irradiation on the roof and faades at various intensities. With these parameters in consideration, solar irradiation has been simulated and analyzed for 12 existing neighborhoods of Singapore along with 36 additional modified neighborhoods.
