[TRNSYS-users] Pvt system

[David BRADLEY]

Fabrizio,
   I'm not sure that it is unrealistic for the outlet temperature of the 
PVT to be higher than the average plate temperature. The average plate 
temperature in a standard solar collector is going to be between the 
inlet and outlet air temperatures. In a PV/T system, the convective 
energy exchange between the back of the plate and the air channel might 
be so bad that the cell temperature gets higher than the inlet or the 
outlet air temperature. Without looking at the project, its hard to 
tell. I would recommend that you look at the Type50 mathematical 
description and determine whether the cell temperature is being used as 
the absorber plate temperature or whether there is a difference between 
those two temperatures.
  Kind regards,
   David
