Hi 
Here is what I like.  Maui software, called Solar Pro
for a bigger more detailed program, the BP solar NSol
for a quick and easy program.  And the Sandia approach
for a basic spread sheet.  As I mentioned in an
eariler post I have compared these with measured
performance over a 6 to 8 year data set.
