Partial shading is a problem that affects the performance of solar modules. Lets imagine a solar module that is composed of 8 solar cells, divided into 2 parallel strings that consist of 4 series-connected cells each. At a certain point, a leaf falls on the module, partially shading two cells: it shades 75% of the area of one cell and 25% of the second one. A sketch of the module can be seen below, as well as the shading caused by the leaf. Not Shaded Shaded Each cell, before the leaf shades some of them, has an open circuit voltage of 0.62 V and a short circuit current of 8.8 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 l-V curve that bests characterizes the PV module when it is shaded by the leaf?
