Rated electrical characteristics are within ±10 percent of the indicated values of Isc and Voc and within +10/-5 percent of
Pmax under standard test conditions (irradiance of 100 mW/cm
2
, AM 1.5 spectrum, and a cell temperature of 25˚C (77°F)).
Under normal conditions, a photovoltaic module may experience conditions that cause more current and/or voltage than
reported at Standard Test Conditions. Accordingly, the values of Isc and Voc marked on UL Listed 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. 690-8 of the National Electric Code for an additional multiplying
factor of 125 percent which may be applicable. In the coverage of Canadian UL listing, installation shall be in accordance
with CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1.
