Dear Andre,
Running some simulations between version 5 and 6 I noticed some differences in Temperature losses as well as in the loss due to the irradiance. There are differences also in the mismatch losses and quality but that you have already mentioned.I have always used the Perez model in both cases and the same meteo and temperature data, so why these differencies still happening?

These differences are due to the PV module parameters.
The version 6 uses different Default values as version 5, especially for the Rserie, which has effects on the low-light efficiency.
Please see our FAQ What explains the difference in yield between different modules?.
