12. SPECIFICATIONS
・
Under certain conditions, a photovoltaic module may produce more voltage and current than reported at Standard Test
Conditions (STC). Refer to Section 690 of the National Electrical Code for guidance in series string sizing and choosing
overcurrent protection.
Module Specification
NOTES
(1) The electrical characteristics are /-5% (UL verified 10% tolerance, according to UL 1703) of the installed values of Pmax and
/-10% of the installed values of Isc and Voc under standard test conditions (irradiance of 1000W/m
2
, AM 1.5 spectrum, and a cell
temperature of 25 deg C).
(2) See module specification sheet for most recent electrical characteristics.
(3) See module drawing for mounting and grounding holes locations.
