[RE-wrenches] Array tilt angle doesn't matter?

[Tom Elliot]

“The further north you go the wider the summer to winter sun angle.”
Bob-O.  Explain this one to me please.  The difference between winter solstice and summer solstice sun angle is 47 degrees, everywhere on the planet, even in Hawaii.  I suspect that in higher latitudes a lower sun angle means more atmosphere to affect insolation but the planet, last time I checked, is tilted the same everywhere.
