Did you get a MPPT solar controler or PWM? You may not be taking advantage of the solar panel capability if you don't have MPPT controller. PWM throws away power if voltage is in excess of battery setpoint, but MPPT will convert to charge current best for solar power available. Also, if you hook panels up in series (say even 75 Volts or so) you can get more efficient charging and less voltage drops to battery with MPPT, check out info on that.
You may be surprised of amount of current loads draw, a battery off switch will help a lot when you don't need any power on, to give recharge some time.
