Viewing and Analyzing Your Data
After saving trace data as described in Saving Trace Data, the information can be viewed
and analyzed using a program that can read a csv file, such as Excel®.
Figure 40 is an example of a csv file showing trace data (not all columns and rows of data
are shown).
Figure 40. Trace data
The first 12 lines of the csv file contain information used for debugging, servicing, or
troubleshooting of the system by Solmetric engineers.
If the Sandia or 5 Parameter Performance Model is used, Lines 13 through 18 display the
five predicted current and voltage points of the selected model (the Simple Performance
Model has no predicted points):

SC – First point, at short circuit current Isc

X – Second point, at one-half of the open circuit voltage

MP – Third point, the maximum power point Imp, Vmp

XX – Fourth point, midway between Vmp and Voc

OC – Fifth point, at open circuit voltage Voc
Figure 41 shows the five predicted points on the measured trace.
