Here is the Excel equation I use for figuring the effective module angle given tilt and azimuth:
Definitely not trivial. I'd sell my proposer software, but the thought of having to provide maintanance makes me shudder.

I'm not sure you understood the problem. Imagine an east facing 5/12 roof, modules mounted flush; simple & clean looking, absolutely, but then we know they will produce more if they were facing more south.....so to get a more south-facing azimuth on the modules, tilt legs on the north side of the modules could be added. So, with these tilt legs now in place, what is my resulting slope and orientation?

Calculating panel angles down to a knat's knee is fine for us type "A" people, but after it's all said and done, my biggest problem with a flat summertime angle is...BIRD CRAP! Man, I'm telling you, as soon as I flattened out the panels around the equinox, these nasty little feathered miscreants took roost and negated any solar gain I might have realized. I actually raised them back up a bit to deter the wreaker's.
