(Thanks to David Wardrick for posting!)

SunCalc is a free little online app that shows sun movement and sunlight phases during the given day at the given location.  You can easily drag & drop the needle to anywhere in the world or just leave it at your given location (if activated).  You can plan ahead by entering in the date of your production based on your production schedule.  Even click on the weather link in the lower right corner to get the forecast for the following week.

You can see sun positions at sunrise, specified time and sunset. The thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon. The colors on the time slider above show sunlight coverage during the day.
