Quantification of trade-offs between an urban policy dedicated to UHI mitigation and one dedicated to renewable energy production via rooftop PV panels
This research paper focuses on the critical examination of a common assumption – that solar panels inherently lead to reduced electricity consumption. While solar panels efficiently convert sunlight into electricity, at approximately 22% efficiency (best case), an intriguing paradox emerges. These panels also generate heat, potentially intensifying the cooling demands of buildings if the efficiency reduces to 8 to 13% (general case). Moreover, they can contribute to the Urban Heat Island (UHI) effect, a dynamic interaction that needs meticulous investigation. Thus, this paper is focused on using building physics and advanced simulations to dissect the reciprocal relationship between solar panels and UHI, specifically in high-temperature environments. As we look at pressing concerns related to climate change and energy efficiency, the impact of solar panels on electricity consumption and the UHI phenomenon is of paramount importance. Understanding how solar panels influence UHI can yield insights that directly inform urban planning and sustainable building design decisions. this paper has the potential to revolutionize our approach to solar panel integration, making it more environmentally conscious and efficient, and ultimately contributing to a more sustainable urban landscape.
