Simplified method to investigate the modules positioning impact on large-scale PV plant performances in Northwest France
Modules modalities (landscape or portrait mounting) affect the losses related to partial shading by changing the internal circuital modules orientation. This partial shading is responsible up to 25% of output production losses in large-scale ground-mounted photovoltaic power plants (Mao, Sunan, Peng...

Modules modalities (landscape or portrait mounting) affect the losses related to partial shading by changing the internal circuital modules orientation. This partial shading is responsible up to 25% of output production losses in large-scale ground-mounted photovoltaic power plants (Mao, Sunan, Peng, Yanlong, & Weiping, 2017). Previous studies succeed in demonstrating, modelling and analyzing the link between module modalities and technical performance losses, putting the emphasis on the electrical effect. Nonetheless, the complexity of the non-linear behavior of modules under partial shading conditions limits detailed studies in reducing studied arrays sizes, neglecting some technical and economic issues of PV project development. Using a dynamic simulation model on PVsyst, this study proposes a simplified method to analyze the social, technical and economic impact of the positioning of modules on a French large-scale ground-mounted PV plant with fixed-mounting structures through a case study.
