E26,
There are a few things here being said that are not your best options, so I'll lay it out.
Panels, you need two 100 watt "12 volt" panels minimum. Expect $100 per panel plus shipping unless you can find them locally.
Charge controller, Use the Brat if you want to go PWM. Quick search, $100 delivered.
Batteries, use two 6 volt Golf cart batteries. 200AH minimum. Expect $150 each.
You have an inverter and the pump. Use them until they quit and then look for a better matched pump.
Using this setup, I would expect 1.2 KWH of power nominal. If it is cloudy in your area often, then cut that in half.
