Table 4

Part of the PM, illustrating the difference in power for the heterojunction PV module (WT75) before and after correction of the temperature according to the ECT procedure described in IEC 60904−5. The difference Δ in W is the After value minus the Before value, within brackets the difference between the two values divided by the Before value giving the percentage value.
