Dev,
   The slopes of the surfaces for which Type15 computes incident solar 
radiation is defined among Type15's parameters.

   In order to plot annual useful energy vs collector slope you would 
have to run your simulation a number of times, each time with a 
different slope then collect the results of each run into a table.
Regards,
  David
