thanx to Xringer, i downloaded the orbitron program and had a better look at the suns orbit from my location.
on DEC 21st the suns elevation is 68.9 degrees to the south at noon
on June 21st the suns elevation is 57.5 degrees to the north, at noon
i think i am supposed to get the noon elevation... not sure, but those are the two maximum positions.
the sun basically sweeps over us between the summer and winter seasons, in November, and again in February, the sun is right on top of us at 90 degrees at noon.
would almost be best to have these panels sitting FLAT on the roof... but that would build up dirt, etc. i think i read it should be tilted at least 10 degrees to allow the rainwater to go off, and wash away dirt, etc.
