Yasir,Unfortunately I don't think it's possible to control the outlet temperature of the collector with just a simple equation. The response of the collector is a dynamic one and I think you'll run into convergence and control issues if you try it. I would suggest that you try either the PID controller or the iterative feedback controller and see if you can get that to work.

Dear sir Greetings I am doing TRNSYS 17 simulation for parabolic solar collector type 1257. I would like to keep the outlet temperature of collector less than a set point by adjust the flow of associated variable speed pump type 1263. How to do this in equation please? Best regards. Eng.
