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.
Despite 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 . As a result, most of the incident radiation is absorbed into the panel as heat and released into the urban environment.
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.
May 2020, 1 (2): 021001 (7 pages) Photovoltaic (PV) panels are commonly used for on-site generation of electricity in urban environments, specifically on rooftops. 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.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
