    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.

    That looks good -- I'd be interested in hearing how it works out for you.

    This is one for iPhone that I'm told does a good job, but its quite a bit more expensive:

    I actually like the manual site survey because it makes people think about sun paths and introduces the use of the Sun Path Charts -- probably the most single useful piece of paper in the universe :)
    The manual survey is a great thing to do with the kids -- everyone should know the basics on how the sun moves.
