Yes,

yes it will, this is done by the Photons special effect.

again yes, You might want to write script to calculate X,Y,Z pozition of 
sun, or input data from external file

POV will probably do both things quite accurate

Btw, I'm writting to Yours email from adress - me {at} raf256 [.] com (in
