timeanddate.com
Time and Date AS is a private company based in Norway that maintains websites in English, German, and Norwegian that first began operation in 1997. In addition, they also make several apps. This site is perhaps the largest website providing this type of information providing the user graphical tools for identifying sun status related information.

SunCalc.net
SunCalc.net is produced by Vladimir Agafonkin out of the Ukraine. It provides a lot less data than other sources, but provides a great graphical display of the sun relative to your location.

NOAA Earth System Research Laboratory
NOAA’s Solar Calculator provides the basic information that most photographers will want. It is a little tricky to set the location with the map interface, but the nice part is that you can directly enter a lat/ long.
