Abstract: In lieu of the rising awareness and concerns of global warming, rate of adoption of solar photovoltaic panels have since grown exponentially. Despite such widespread adoption, knowledge of the impacts of such mass deployments of PV panels on the local microclimate is limited. With studies conducted thus far having yet been able to yield a unanimous conclusion on the potential impacts. However, some researches have postulate that urban PV installations may potentially cause a “heat-island” effect, further exacerbating another issue that plagues the urban environment, the UHI. Therefore, it is imperative to ascertain this potentially detrimental effect and also to identify and evaluate other influencing factors that may contribute or minimise this threat for future successful implementation of rooftop PV panels. This study employs a qualitative and quantitative approach in tackling the above question. Results of findings have identified that even though PV panels act as a heat source during the day, the indirect effect of shading still supersedes that of the effects from the emission of longwave radiation, having an overall cooling effect on the local environment. However, in the night-time, PV panels may have a moderate heating effect due to impairment of ventilations. Through literature reviews and field measurements, environmental and PV configuration related variable were also positively identified and assessed on their impacts. Results of this research would aid in adding on to the currently limited body of knowledge in this field and provide a certain degree of empirical data to be built upon in future studies with the goal of promoting a synergistic relationship between rooftop PV panels and their local environment.
