Abstract: Building-installed Photovoltaic (BPV) provides solutions to improving energy flexibility in urban areas. There are two problems: 1) the simple view factor is inapplicable to cities; 2) Partial Shading Conditions (PSCs) are the main cause of power loss in urban areas. Moreover, the PSCs increase the difficulties in estimating performance and designing a BPV system with higher efficiency. This work implements the Building Environment Analysis Tool (BEA) to help design BPV configurations and proposes installation strategies under dynamic PSCs. This work designs a dual-building model to study the performance of the BPV system under PSCs. In addition, the paper considers the series-parallel (SP) and the total-cross-tied (TCT) for the PV system’s configuration to mitigate the PSCs’ effect. Based on the PV configuration and the double building model, this article studies the impact of the height and shape of the neighboring building on the performance of the BPV system. Based on the simulation results, this article provides guidelines for designing more efficient BPV systems, considering their environment.
