Partial shading is a problem that affects the performance of solar modules. Let's imagine a solar module that is composed of 16 solar cells, divided into 4 parallel strings that consist of 4 series-connected cells each. At a certain point, a leaf falls into the module, partially shading three cells: it shades 5% of the area of the bottom left one, 60% of the area of the bottom right one and 10% of the one in the top. A sketch of the module, with the leaf on it, can be seen below. Each cell, before the leaf shades some of them, has an open circuit voltage of 0.60 V and a short circuit current of 6.2 A. Assuming that all the interconnected cells have identical electrical characteristics, and that they experience the same temperature and insolation, what would be the approximate I-V curve that bests characterizes the PV module when it is shaded by the leaf?
