What is a good way to test a solar panel for maximum wattage?

When I connect this panel to a motor it seems I'm getting 30 watts but when I attached it to a big 3 ohm resistor the voltage drops to 6 volts and I'm reading only 2 amps which would be like 12 watts. With the motor as a load the voltage stays around the rated 34 volts.
