Hi Austin,
When that NASA job disappeared, you should have moved to the NSA, they're growing like crazy..
Anyways, here's the best site to use for PV angle finding..
UO SRML: Sun chart program
It gives you a nice printable chart output..
Here's what mine looks like..
I've got quite a bit of swing (north of Boston)..
So, I've made my elevation angle adjustable. I'll have to make a new chart,
if I ever move back home to Texas..
