There are a number of offerings at

probably find useful.

Elevation ia actually called Altitude.

I have links to some web pages that can do this at:
http://www.redrok.com/analemma.htm
Especially the astronomy codes by Keith Burnett. See:
http://www.redrok.com/analemma.htm#burnett

In addition yo AZimuth and ALTitude, Burnett's programs
also give the solar Right Ascension and DEClination.

What are you planning on building?

You can also just use a Sun Chart from:
