I've been trying to find a good site on our property for my planned ground-mounted PV array.  We live in a heavily wooded area with some cleared space.  I'm willing to trim/fell some trees if needed but wanted to minimize that. 
 
I came across this app for Android devices and thought others here might be interested. It uses the accelerometer, GPS, and compass in a phone to allow you to map your horizon with respect to the sun's movment to predict site potential.
 
Its expensive as Android apps go ($14) but well worth it to me if it does what it says it does.
