Notes
1. These data represent the performance of typical MSX 60 and MSX 64 modules as measured at their output
terminals, and do not include the effect of such additional equipment as diodes or cables. 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/m2 (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 Pmax.
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/m2, and wind speed of 1 m/s.
4. The power of solar cells varies in the normal course of production; the MSX 64 is assembled in limited
quantities using cells of slightly higher power than the MSX 60.
