Predicting the I-V characteristics of PV systems under partial shading

Researchers in Tunisia have proposed a method of determining the characteristic I-V profile of a partially shaded PV module, and to extrapolate it into a string profile.A research group from Tunisia's Carthage University has developed a method of analytically determining the characteristic I-V profile of a PV system under partial shading. Described in the study Modeling PV installations under partial shading conditions, published in SN Applied Sciences, the method was conceived to determine the I-V characteristics and to use them to profile PV module strings. The method was tested on two parallel, ...
