I've tried using different modules to attain different results, but the "PV loss due to temperature" is always 10%. The site is located in South America, Brazil.

As recommended, I am not going to mess with the pv modules specs, but I believe this might be a limitation being caused by the the default parameters set by PVSyst.

If it is indeed a hidden parameter that must be changed in order to attain accurate results, please help me change it as well as recommend parameters that are used in Brazil.

Thank you!

There is no specified limit here.
The Temperature loss is related to the muPmpp temperature coefficient of your modules, and the array temperature TArray.
It is evaluated using the one-diode model and the thermal model described in the help "Project design > Array and system losses > Array Thermal losses"
