Simplified modeling for partially shaded PV systems

A proposed two-diode model is based exclusively on the standard test condition parameters of solar modules and their irradiance levels. The analytical tool reportedly enables PV system operators to estimate the I-V curves of a shaded array quickly and accurately.

Mitigating shading in PV modules with new reconfiguration technique

Scientists in India are seeking to mitigate partial shading with a technique based on the Lo Shu nine-square grid of ancient Chinese mathematical tradition. Their approach features the ‘magic grid’ also used in popular sudoku puzzles, as a guide for reconfiguring arrays.

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.
