2.1 MEASURED DATA
Black & Veatch used the TÜV test data supplied by REC to generate measured efficiency curves of
the module as a function of irradiance and module temperature. The rated power (P
mpp
) of TÜV test
samplesvariedfromthemodule’snominalpower on the datasheet, but this variation was reduced
by scaling each sample to achieve its precise nominal power at STC.
Measured test data was not available for the REC245PE module, therefore Black & Veatch used the
measured test data for a REC240PE module and then scaled the data to reflect expected efficiency
curves for a REC245PE module. The scaled REC240PE data was used to calculate the module
efficiencies at test conditions. Efficiency is calculated as:

Figure 1 shows the scaled measured curves which define efficiency as a function of irradiance and
module temperature for a REC245PE module. A comparison of measured maximum power at STC
(25°C) and (NOCT) (45.72°C) is shown in
Table 1 below.
