Here we show that, in Kolkata, city-wide installation of these rooftop photovoltaic solar panels could raise daytime temperatures by up to 1.5 °C and potentially lower nighttime temperatures by up to 0.6 °C.
The back panel temperature of the solar panel is similar to the roof temperature for the exposed roof. However, since the roof surface underneath the PV panel is shaded its temperature is significantly lower than for the exposed roof.
Our study also reveals that rooftop photovoltaic solar panels significantly alter urban surface energy budgets, near-surface meteorological fields, urban boundary layer dynamics and sea breeze circulations.
From 0900 to 2100 PST the ceiling under the exposed roof is warmer than the ceiling underneath the flush panels, which in turn is warmer than the ceiling underneath the tilted panels. The maximum temperature difference between exposed roof and tilted PV is 2.5 °C at 1700 PST.
