The panel wattage seems to be adequate, the batteries are up to 12.6 by afternoon, however the battery voltage is about 11.9 in the mornings after a night with 2 cpap machines running.
Battery voltage should rise to 14V+ for bulk charging and then taper down to absorb on the way to 13.4V for float. Up to 12.6V is way low for a full charge.
Experience is a fantastic teacher. Recommend you buy 2 more AGMs, a battery moniter I suggested in your other thread and learn. Then you'll have a better base of knowledge for upgrades. Start with your battery specs - what are the recommended charging voltages?
