Dear Monica,

The component you're using for solar collector requires a detailed description of the construction of the collector. 

There is another collector model with fewer user inputs required. The default parameter values in the plant database for this component are based on actual rating data for a collector available here in the Canadian market. Here is the plant database entry for this component:

  ---------------------------------------------------------------------
  PLANT COMPONENT                                           No :     84

Subject: solar collector "segment"

Hi ESP-r user,

 

I try to start a solar collector. I choose the flat plate solar collector "segment". To fill in the right values I have some questions:

 

Collector mass (kg): Mass of tubes and sheet material? Allover mass, incl. absorber, glazing and side-construction?

 

Collector mass weighted thermal capacity (W/kg K): Is the unit correct? After reading in the source code, I assume, that the unit shall be Wh/(kgK) or Ws/(kg K).

 

Collector transparent surface area (m2): ?

Collector opaque surface area (m2): ?

 

 

g) flat plate solar collector "segment"

 

 

 

Does someone have experience with a solar collector?

 

Thank you.

 

Best regards
