Yes with a low sun tilt matters more. I ran a test at 49N on 18 May with a 130w panel and got 8.3a tilted, but 7.2a flat at noon.
On 23 Sep I was in the same spot but with a 255w panel. With it flat I was only getting approx 11 amps at noon instead of approx 16a tilted at noon. (noon at 1300 )
1.1/7.2 = 15.% boost from tilting in late May
5/11 = 45% boost by tilting in late Sep (at 49N)
The bigger problem here in winter is just getting the sun to be above the tree tops.
