In this final episode in the PVsyst series, Daniel Tarico and Frances Plourde discuss the impact of system design on photovoltaic (PV) system modeling, focusing particularly on shading losses and module mismatch within the context of using the PVsyst software.
Frances also covers light-induced degradation (LID), which happens when PV modules are first exposed to sunlight, particularly affecting crystalline silicon modules with certain dopants. LID is a one-time effect but can reduce module efficiency by 1-3%. This factor must be accounted for when designing and modeling PV systems, especially for long-term performance projections.
The conversation highlights the importance of considering the long-term effects of module degradation, mismatch losses, and shading when designing and financing PV systems.
