For a 24 volt system the panel at max power rating needs to be 32 to 36 volts. Roughly 16 to 18 volts for every 12 volts of battery. However that rule only applies if you are using a standard PWM or shunt regulator. Using that type of regulator you will loose 30% minimum of the power from the panels.

[pdf] The recommended method for charging a LiFePO4 battery pack is the CCCV (Constant Current, Constant Voltage) approach: Constant Current: Charge the battery at a rate of 0.3C. Constant Voltage: Once the battery reaches 3.65V per cell, switch to constant voltage charging.
