george__ Posted February 27, 2018 Share Posted February 27, 2018 According to PVsyst's manual:"the I/V characteristics of the partially shaded sub-module is evaluated (10% cells shaded for 1 corner shaded, 1/3 for 2, 2/3 for 3, 100% for 4 corners). It is again an approximation, but when inserted in the I/V full array characteristics the electrical effect is about the same as soon as the sub-module is shaded."Full Calculations steps: http://files.pvsyst.com/help/near_shadings_electrical.htmI wanted to know what the 10%, 1/3 and 2/3 (in step 2) meant with reference to IV characteristics? P.S any explanation or further information on how PVsyst's calculation method would be much appreciated as I'm not sure I fully understood it.
