Notes
1. These data represent the performance of typical modules in 12V
configuration as measured at their output, and do not include the
effect of such additional equipment as diodes. The data are based
on measurements made in accordance with ASTM E1036
corrected to SRC (Standard Reporting Conditions, also known as
STC or Standard Test Conditions), which are:
• illumination of 1 kW/m
2
(1 sun) at spectral distribution of AM 1.5
(ASTM E892 global spectral irradiance);
• cell temperature of 25°C.
2. During the stabilization process which occurs during the first
few months of deployment, module power may decrease
approximately 3% from typical P
max
.
3. The cells in an illuminated module operate hotter than the ambient
temperature. NOCT (Nominal Operating Cell Temperature) is an
indicator of this temperature differential, and is the cell temperature
under Standard Operating Conditions: ambient temperature of
20°C, solar irradiation of 0.8 kW/m
2
, and wind speed of 1m/s.
