Rooftop PV installations could raise daytime temperatures in urban environments by up to 1.5 C

New research from India shows that rooftop PV system may have "unintended" consequences on temperartures in urban environments. Rooftop arrays, for example, may potentially lower nighttime temperatures by up to 0. 6? C. An international group of scientists has created a new model for the assessment of rooftop photovoltaic solar panels (RPVSPs) in urban microclimates. The module utilizes the latest weather research and forecasting (WRF) model, integrating the building energy model (BEM) and the building effect parameterization (BEP) into it. The model was validated against ten observation stations ...
