Electrical Ratings

Rated electrical characteristics are within +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.
