Abstract
Building integrated photovoltaic (BIPV) systems are a crucial component of the transition to a low-carbon energy system. However, current simplified models of PV cells and modules used in building and urban energy simulations may not accurately capture the performance of various PV technologies under partial shading conditions. In this paper, we propose a novel framework for modeling parametric BIPV arrays using a highresolution irradiance grid and a power model that operates from the evaluation of IV-curves at the cell level to the AC to DC conversion in the inverter. This allows us to combine PV modules of varying sizes and electrical configurations based on the selected inverter type, and to capture the operative benefits of multiple types of cell technologies, module designs, and electrical layouts in building-based PV applications. We evaluate the proposed framework by comparing its performance to measurement data and to three other frameworks found in the literature through the simulation of two BIPV fac¸ades and a tilted rooftop array. The results show that the proposed framework is necessary to account for partial shading (if present) as well as provide operative details when the type of inverter to be used is in question. Overall, this paper presents a novel framework for modeling the performance of PV cells and modules in building and urban energy simulations, which has significant implications for the design and optimization of building-based PV systems.
