Edit: Sorry, didn't answer all your questions. You can add a second 150 watt panel. If connected in series, you would see a maximum of 22.5 volts and 16.76 (8.38 amps times two). If connected in parallel, you would see a maximum of 45 volts (22.5 volts times two) and 8.38 amps. According to the specs I see for your controller, both are within it's limits. Also remember, panel "max" specs are under ideal conditions which don't exist in the real world.
You mixed up series and parallel here.
Putting power sources in parallel would force them to operate at the same voltage (the single panel voltage in this case) and the currents would sum. Putting them in series would have the same current flowing through both (the single panel currents) but the voltages would sum.
