[TRNSYS-users] New TESS Solar components

[David BRADLEY]

Andrés,
   Jeff is currently out of the office and while I am not certain, I 
would be very very surprised if you were not able to specify a different 
flow rate than the tested flowrate; it is standard practice for 
collector models to correct for the performance impact of running at 
other flow rates than the tested one. To be certain, check the "more" 
button contents on the various parameters and inputs of the model.
Kind regards,
  david
