The carbon intensity of integrated photovoltaics

Christophe Ballif, Nicolas Würsch, Alessandro Francesco Aldo Virtuani, Alejandro Borja Block

To assess the meaningfulness of installing solar photovoltaics in buildings and infrastructures, we consider a carbon intensity (CI) balance perspective and assess whether installing PV at different orientations acts as a net CO2 sink or source, when compa ...
