I live in Australia and suspect that the application is not valid for the southern hemisphere, as the ordinal letters (N, E, W, S) do not line up with 0, 90, 270, 180 degrees and I appear to have only 90 degrees of movement when I rotate my phone through 360 degrees in azimuth for taking the horizon scan. Unless changes can be made to what appears to be a well thought out application, I recommend that southern hemisphere users leave it alone.
Some fantastic functionality for a free app. Easy to use and good documentation. The big problem is that it never tells you angles used to make the final graph. i.e. Tilt, and degrees from north. Which is a major pain if you're wanting to use that data to make a frame too hold the panels. It would be great if you could see these listed on the graph at the end.
Really great tool for investigating solar potential in particular place. Addition: It would be great to display numerical values for current tilt/azimuth along with effectiveness percentage.
Perth Australia Worked easily and gave very believable result in Australia. Very useful results.

* Fixed memory issues reported by review of user nicknamed 'ilkosj'
* Now ScanTheSun knows how a solar panel "sees" direct sunlight.
* Optical characteristics of solar panels are taken into account (the range of acceptance angles at which the panel is able to intercept the radiation).
* The app knows how a panel "sees" the incidence light. It allows to measure the effective insolation i.e., the amount of solar energy being intercepted by the panel from incidence radiation.
