6.1 Electrical property
There is a tolerance between the nominal values of modules such as Isc, Voc and Pmax
under standard test conditions, perhaps the value is relatively higher compare to the value
obtained under component standard test conditions. Therefore, in the determination of
photovoltaic system accessories, such as rated voltage, wire capacity, fuse capacity and
module power output and related parameters, the relating short current and open voltage
amplify 1.25 times can be applied.
