Electrical Installation
6.1
Electrical characteristics
Module electrical ratings are measured under Standard
Test Conditions(STC: 1000W/m
spectrum and a cell temperature of 25°C). Please refer
to the datasheet or the product nameplate for the main
electrical characteristics, maximum system voltage and
tolerance of Isc, Voc and Pmpp.
Under certain conditions, the output current and/or
voltage of the PV module may be higher than the value
under standard testing conditions. Therefore, the value
of Isc marked on the module should be multiplied by
1.25, and Voc on the module should be multiplied by a
correction factor (see table 3 below) when determining
component ratings and capacities. Depending on your
local regulations, an additional 1.25 multiplier for the
Isc(giving a total multiplier of 1.56) may be applicable
when sizing conductors and fuses.
