Solar Time Calculator

By American Technical Publishers, Inc.

Open iTunes to buy and download apps.


The Solar Time Calculator provides the ability to easily convert clock time (standard or daylight saving time) into solar time, as well as from solar time into clock time. This handy app simplifies the conversion into a single button press.

Solar time is a timescale based on the position of the sun relative to a local position (longitude). Clock time usually differs from solar time, though the magnitude of the difference varies. Thus, actual solar noon (when the sun is directly overhead) is up to about +/- 45 min for most locations, and is caused by two factors: the date and the location. The Solar Time Calculator uses these factors to calculate the actual solar time relative to the position of the sun.

Solar time is useful when conducting shading analyses, optimizing photovoltaic array orientation, and performing other calculations in the field of solar energy systems.

Needs an info section

Wanted to use an app to measure solar time in my area. Not sure this app does it because there are no basic instructions on how to use it. Would be nice to have something assist with finding my longitude also. You have to have all the info to use the app, so in the end you only spin dials. :-(

Great but...

would be even greater if could work in Europe ?!!

Suggestion for improvement

To determine solar time to the nearest minute, you need to know the longitude to the nearest quarter of a degree. This app does not permit that fine a distinction - even when using gps to determine longitude. Using all available precision in determining longitude would greatly improve the app.
