[esp-r] Modelling solar collectors in ESP-r

[keul at stud.ntnu.no]

Dear All,

In ESP-r there are only models for flat plate collectors. Do anyone  
know if it is possible to use any of these models for evacuated tube  
collectors if I have the constant coefficient, the linear coefficient,  
and the quadratic coefficient of the efficiency equation? How precise  
will the results be in that case?

Best Regards
