The obvious answer is perpendicular to the sun is the best.
In other words if you can track the sun that would be the most effective way to absorb energy.
At our latitude the average angle for both winter and summer I'd between 30 and 35 degrees.

Depending on your setup, a good way to not worry about the angle too much is to add a few more panels. My installation has roughly 7kw panels for a 5kw charge controller inverter combination and it just helps that you use the max capacity of your equipment for the largest possible time of the day.

My roof faces true north but at a flattish 7 tilt. I was told to mount flush for aesthetic and wind load considerations.  I found an online calculator (it may be the one Gerlach mentioned) that showed me losing on average 8-10% of efficiency. So I increased my panels from 12 to 14 and am smiling all the way.
