A PWM solar controller takes output from the solar panel can pulses it (the P in pulse width modulated) to make the voltage compatible with what the battery needs. But the pulsing wastes a bit of the power. MPPT controllers (maximum power point tracking) convert the incoming voltage to what the battery needs without wasting any. They can even convert higher voltages like are produced when two panels are connected in series to match what the battery needs with little waste.
So check the specs on your controller which is almost certainly a PWM. If it is good for 15+ amps then wire your panels in parallel- pluses to pluses, negatives to negatives.

My goal is to install two additional batteries. Everything works well as-is, except in the winter when the heater is working overtime. The fan runs out of power for the fan motor by 4 AM, then the generator has to kick on. I can't seem to get the AGS working like it should. I think I don't know how to set it up. But extra power would be helpful. It looks like the existing controller should handle the extra panel.
