Let’s start by calculating the minimum number of modules that we should have in a series string. This is a three-part calculation. Vmin = (Vmp + ( (THigh + TRise - TStc) x (VmpCoef x Vmp/100))) Vmin = 36.7V + ( (35ºC + 32ºC - 25ºC) x (-0.43 x 36.7/100))) Vmin = 36.7 + (42 x -0.158) Vmin = 30.064 V [pdf]
