Integrating PV panels into urban infrastructure is no longer an option—it's an essential step toward achieving sustainable, energy-resilient cities. In this guide, we explore how utility-scale solar can be integrated into urban infrastructure design, the key. Deploying photovoltaic (PV) on rooftops, water bodies such as hydropower reservoirs, and along roads and railways could push the EU total installed capacity in excess of 1 TWp without compromising the environment, a new JRC study reveals. This model aims to provide reasonable universal calculations regarding a city's available space for mounting rooftop photovoltaic systems and their corresponding annual electricity. Urban areas offer vast opportunities for solar energy generation through rooftops, facades, and vacant land within the city limits.
