How much voltage and wattage does a SON hub dynamo supply?

Nominal values are 6 volts and 3 watts and are achieved at moderate speed (depending on wheel size and generator). However, the real values depend greatly on the electrical load. Without a load, higher no-load voltages also occur. When driving fast, you can draw significantly more power with a suitable load.
