Abstract

In this paper, a comprehensive analysis on the local maxima developed in a partially shaded PV string, experiencing multiple irradiance levels, is presented. The number and the trends of the local and global maximum power points (MPPs) are studied, initially considering two irradiance levels and subsequently extending to the more complicated three-irradiance levels scenario. The shading patterns at which each MPP appears are investigated, and the conditions under which they constitute the global MPP (GMPP) are identified, while the effect of the operating temperature and the intensity of irradiance is studied.
