CAUTION: READ USER’S GUIDE BEFORE USING THIS PRODUCT
Electrical specifications are rated at Standard Test Conditions STC (Irradiance of 1000W/m², AM 1.5, cell temperature 25°C). During the stabilization process that occurs during the first few months
in service, module power output will exceed specified ratings. Power output may be higher by 20%; operating voltage may be up to 10% higher; operating current may be up to 14% higher; and
short circuit current may be up to 10% higher.
