Photovoltaic Panels on Green Roofs: Optical, Thermal and Electrical Contributions in a Multi-Energy Model
Abstract
As the transition to renewable energy accelerates, optimizing photovoltaic (PV) systems becomes essential by considering their interactions with physical and climatic environments. Additionally, urban architecture has evolved in recent decades with the advent of buildings featuring flat and green roofs. This research examines the integration of PV panels on green roofs through a coupled optical–thermal–electrical (multi-energy) model and an experimental validation under real operating conditions. To accurately model these synergistic interactions, the study considered various electrical, thermal, and optical factors that influence PV conversion efficiency. It provides a comprehensive set of tools for understanding the dynamics of energy efficiency in PV panels installed on green roofs, identifying performance determinants, and evaluating design implications under different environmental constraints. The results highlight that temperature-driven losses and convective cooling conditions are key determinants of PV performance on green roofs, and the coupled formulation is necessary to capture their combined impact. Global and detailed multi-energy models were validated using experimental PV and environmental data collected from a PV panel installed on a green terrace. The validated framework provides a consistent basis to interpret measured PV behavior and to support design-oriented assessments of PV-on-green-roof configurations under realistic environmental forcing.
