Wanted to let any interested parties know I have some free astro tools
on the web. I created a tool called Ted's Toolbox with many functions
- from Lunar and Solar calculations to Sidereal and Nutation
parameters as well as Time conversion routines, ECEF to Geodetic
transformations and GPS information.
The tool is located here: http://www.teddriver.net/java/toolbox.htm.
Read, then scroll down to the download button. There is also an
applet version located here: http://www.teddriver.net/java/java_applets.htm,
but the applet version does not have the plotting, exporting or
location saving features.
Enjoy!

Were you using an IDE such as Borland's JBuilder, or were you writing
from scratch?

Just curious,

I'm interested in some Solar-PV calculations.
I have used http://www.gcstudio.com/suncalc.html to plot a day's transit.
I happened to notice that the sun was shining directly on my solar panels
the other day.

I'd like to be able to input my location and discover the time that the sun
would be at 214 az 26 el from here. That's the inverse of the programs I
find on the web, including yours.

Another use of gcstudio is to put in a time that you observed a shadow
falling in a particular direction, like exactly along a wall, and use that
for siting the angle of that wall.

All done in Netbeans 5.0 - an IDE built in Java. Programming GUIs
from scratch is not fun! Here's the link: http://www.netbeans.org/products/ide/index.html

They are not complete yet, but if you have a question about a
particular tool, feel free to e-mail me.

I don't understand what you provided. Is there a date here that I don't
see? Or is this solution for azimuth only, on today, where the elevation
at 14:16 is 34 degrees?

Quote:
It would be easy to plot (say) elevation as a function of date for a
given azimuth if that would help.

Yes. I wanted to know the time and date when the sun would be at 214,26
from my perspective at 38.8,-122.5

That example was run in APL2 for OS/2. I also have the old APL2 for DOS
which allows producing a .exe that can be given to someone that doesn't
have APL2. If that would help, I could see if the above would run in
the older APL2. It likely would.

Since the shadow direction is simply the sun's azimuth -180, that's even
easier. e.g.
38 -122.5 -8 Sun_pos 70219, Time'12:34:56'
183.6 40.75

The answer is:

29 Jan 2007 22:30:12 (UTC) (14:30:12 local) and
12 Nov 2007 22:01:14 (UTC) (14:01:14 local)

I did this analysis in Satellite Tool Kit (STK), here's a pic of the
situation:
