Sun Seeker 3D

Now that we have an awesome solar power setup (AM Solar rocks!) the question arises – Will we have sun at this campsite?

I found this cool iPhone app called Sun Seeker 3D. It uses the iphone's built-in GPS to figure out where you are, the date and time to correlate to sun position tables, and the iPhone compass and accelerometer to figure out what direction and orientation you're pointing the iPhone camera.

All of that sounds complicated, but the result is easy. You turn on the app, switch to 3D view, and point the phone at the sky. On the display for the camera, it shows you where the sun is , the path the sun will take through the sky, and what time it will be at each location. It seems accurate so far.

If I aim it up through the skylight of the trailer, I can see when the sun will shine on the solar panels.

The photos below are samples I took pointing it up through the skylight (which is between two solar panels, conveniently.)
