I did play around with numbers on there and came to that conclusion.
Considering I'm only 50 miles from international falls, it's even a clearer
choice then running the numbers in the cites.
Verification is always nice!

Jesse,
Running PVWatts for various tilt angles with an azimuth angle of 135°
(or 225°) for locations in Minneapolis, shows that the optimum tilt
angle for annual energy production is about 35°, that's almost the same
as the optimum tilt with an azimuth of 180°. To maximize December energy

Does PVWatts really account for hourly weather data such as overcast conditions
in the afternoon? I think it just accounts for average solar radiation for a
particular location on a monthly basis but I could be wrong. Anyone care to
chime in?

Allan,
That is pretty much my thinking. They have 0 interest in stepping foot roof
and the SE give more tilt and easy ground access to clear the array during
winter.
I appreciate the advice.

Jesse,
Based only on the info you provided, I'd recommend the SE face. A
low slope is best for maximizing annual gain, which is what a
conventional grid-tie customer would want. But you are in essence
giving them a system that will function as GT now, but as an of

Jesse,
A good decision can be based on, among other site/load specific details, the
site
We do tend towards clear mornings and clouding up in the middle of the day.
Today was a good example of it. I did use PV watts and didnt see a big
difference between the two.
Thanks Benn

Do they tend to have clear mornings and cloudier afternoons/evenings?

Maybe throw the different directions into PVWatts and s
