Free QuoteDespite numerous benefits, there are potential negative impacts from rooftop PV implementation. Currently installed photovoltaic panels typically convert only 15–18% of the incoming solar radiation into electricity [ 7 ]. As a result, most of the incident radiation is absorbed into the panel as heat and released into the urban environment.
There is also not a clear consensus on the impact of rooftop PV panels on building heating and cooling loads. The majority of studies suggest that rooftop PV arrays provide beneficial shading to the building and reduce cooling loads [ 15 – 19 ].
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.
However, their implementation on rooftops poses potential (positive and negative) impacts on the heating and cooling energy demand of buildings, and on the surrounding urban climate. The adverse consequences can be compounded if PV is installed on top of an otherwise highly reflective (“white”) rooftop.
Overall, owing to the temperature-adaptive solar absorptance and thermal emissivity, the proposed rooftop covering achieved higher roof surface temperature than the conventional heating and cooling materials in cold seasons, while it achieved lower roof surface temperature than the two in hot seasons.
