The panels in the pic are referred to as 24V panels. They are the very large 72 cell 36V panels. You will need a MPPT controller that can handle 1 or 2 in either parallel or serial. Serial is actually better for shading if that is a concern for you.
For your parallel 12V panels (36 cell) be sure they are all within about 0.5V output. For this setup a PWM controller is the best option.
This may help you: The PWM controller uses the panel amps to charge the battery. The MPPT controller is designed to take the higher 24V panel voltage and it's amps and convert it to the lower battery voltage with higher amps.
