Electrical Ratings
Rated electrical characteristics are 10 percent of the indicated values of Isc, Voc, Pmax under Standard
Test Conditions (irradiance of 100 mW/cm², AM 1.5 spectrum, and a cell temperature of 25°C {77°F}).
The electrical characteristics are based on the results of outgoing test.
Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or
voltage than reported at Standard Test Conditions. Modules should be multiplied by a factor of 1.25 when
determining
component voltage ratings, conductor
capacities, fuse sizes and size of controls connected to the
module output. Refer to Sec. 6908 of the National Electric Code for an additional multiplying factor of 125
percent (80 percent of rating) which may be applicable.
Please refer to Section 690-8 of the National Electrical Code for an additional multiplying factor of 1.25 which
may be applicable.
