Deployment of rooftop solar photovoltaic electrification for residential buildings in Saudi Arabia’s industrial city: A study on public perception and acceptance in Yanbu Industrial City

Abstract

Solar-based power generation is gaining attention worldwide as it is environment-friendly, and highly sustainable. Saudi Arabia is bestowed with vast solar energy availability. This should be the driving force for generating solar electricity to the optimal. However, the installation of solar photovoltaic (PV) is not as widespread as expected. As purposed-built cities emerged from the Kingdom's new economic development and renewable energy initiatives, they should lead the way for solar energy utilization. This paper aims to investigate the public perception and acceptance towards rooftop solar electrification in such cities in Saudi Arabia. Survey questionnaires were distributed to a sample population of Yanbu Industrial City to measure the perception, and readiness towards installing rooftop solar systems and gauge the populace's concerns. The outcome shows a variation of awareness levels, positive perception, and mix-readiness towards installation. The main barriers are the relatively low cost of fossil fuel-based electricity and the lack of clear incentives from authorities. Homeowners are more willing to invest in solar electricity for long term gain. Household income also has significant effects on the willingness for investment. The scenario analysis indicated that less than six years of payback could be achieved with the PV system which can be an attraction.
