2.5V to 4.2V are the extreme limits of discharge and charge without immediate damage on LiFePo4. There is little reason to push the cells to these limits because they are well past the knees of the curve and the last .5V-.75v past each knee adds very little additional storage.

There is no realistic way to ''hold'' cells at 2.5V and when you discharge to 2.5V or 2.8V and then stop discharging, the cells are not being ''held'' - they relax to a higher voltage determined by their exact SOC (and also largely determined by the discharge current before hitting the Low Voltage cutoff voltage).

You need around 40 watts of solar panels to charge a 12V 20ah lead-acid battery from 50% depth of discharge in 4 peak sun hours with an MPPT charge controller. You need around 70 watts of solar panels to charge a 12V 20ah Lithium (LiFePO4) battery from 100% depth of discharge in 4 peak sun hours with an MPPT charge controller.
Charge Cycles and Depth of Discharge. LiFePO4 batteries have a specific number of life cycles, each of which consists of a charge and discharge cycle. The excessive depth of discharging like discharging the battery to very low levels leads to the acceleration of the capacity degradation and a decrease in the lifespan of the battery.
