New research confirms rooftop PV affects urban temperatures, cooling demand
Using Lyon as a case study, an international research team has simulated the effects of rooftop photovoltaic (PV) coverage in an urban area at three levels: 25%, 60%, and 100%.
The results have shown that solar panels can raise daytime temperatures by up to 0.72 °C, while cooling nighttime temperatures by up to 0.42 °C. In addition, daytime air conditioning demand has decreased by about 5%.
