Jesse, A good decision can be based on, among other site/load specific details, the site's "micro-climate".
Do they tend to have clear mornings and cloudier afternoons/evenings? ...or cloudy/foggy mornings and clearer afternoons/evenings? Maybe throw the different directions into PVWatts and see what it says, since it is based on weather history (isn't it?) Good luck. benn Sent from a 'smart' phone, with touch screen keys.
