Testing

A round-robin outdoor methodology has been applied to establish the performance of the developed CPV
modules in order to provide an evaluation of the uncertainties of measurements between different test locations.
To provide a fair comparison between the different results, the performance of each set of tests was normalised to
a set of standard test conditions (STC). These were:

p direct normal irradiance: 900 Wm ;
-2
p cell temperature: 25 C.

Due to the uncertainties involved in measuring the DNI spectrum (see Chapter 9), no correction was applied for
change in the spectral conditions. All tests were performed at solar noon +/- 1.5 hours to avoid large variations in
spectrum. The results of the I-V inter-comparison are reported in Figure 67 and Table 9.
