Need Help Trouble-shooting Solar

Have a 160W panel on the roof (not sure of brand), a Go Power 30amp controller and 2 6v interstate flooded batteries. Everything in its first season of use.
Had a less than optimal exposure, ie faced in a way that the roof top ac unit always cast some shade on the panel, but located in AZ and had cloudless skies with a good 8+ hrs of sun daily.
The main symptom I observed was that the Go Power controller would show .5amps by 8:30 am but would never go higher even as the sun rose and panel shadowing reduced. volts never rose higher than 12.6. Over 3 days of camping with very conservative use of 12v, according to the Go Power, batteries dropped to 73%. After a 2 hr drive home, batteries were at least 90% again.
My theory is that the controller is failing to recognize when the batteries drop and is not directing the power to recharge them.
I need some help and suggestions in trouble shooting this to determine exactly what is wrong and then how to fix if possible, or what to replace.

Give Charmana or GoPower a call +18662476527 I have always been very happy with their service.
