C) ELECTRICAL INFORMATION
ELECTRICAL RATINGS
Rated electrical characteristics are within ±10 percent of the indicated values of Isc, Voc and 10/-5 percent of Pmax under Standard Test Conditions
(irradiance of 100 mW/cm2, AM 1.5 spectrum, and a cell temperature of 25˚C (77˚F)). The warranty conditions are specified elsewhere in this manual.

Under normal conditions, a PV module may produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values of Isc
and Voc marked on UL 1703 listed modules should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities,
fuse sizes and size of controls connected to the module output. Refer to Sec. 690-8 of the National Electrical Code for an additional multiplying factor of
125 percent (80 percent de-rating) which may be applicable. Where Canadian UL listing applies, installation shall be in accordance with CSA C22.1, Safety
Standard for Electrical Installations, Canadian Electrical Code, Part 1.
