How To Defile Solar Energy Technologies In Aspen Plus?

Hi everyone.

I have a challenge to overcome, and this is: finding a way that can change the reboiler duty in an absorption column. Actually, the thermal load of the absorption column is being satisfied by solar energy, and since solar radiation varies throughout the day, I want to find a way to apply 8760 different reboiler duties (representing the amount of energy produced by the sun for 1 year with hourly time resolution) and obtain results.

I don’t know how this is possible. Should I necessarily use Aspen Dynamics? Should I define a User-Defined Model and code it myself? Or should I focus on the ‘Utility’ of the column reboiler?

I would appreciate it if you could share your thoughts concerning this challenge.
