I would avoid mppt if you want to do it cheap.
Get two 12V, 140W panels for $160. The pwm controller costs about $30.

I really dont understand much about solar charging or electricity for that matter.
Would that mean that theoretically these panels would be capable of putting 23.3 amp hours into my batteries? 2×140 watts÷12 volts =23.3 amps.
As a practical matter how many amp hours could you expect to add to your battery bank on an average day?
