[TRNSYS-users] Solar Panel Type 1b

[Carstens, Patrick]

Hi Trnsys-Users,


I would be pleased to get some detailed information and help for the type 1b.
I wanna simulate a solar-supplied heating system. In addition to it I use the type 1b for a solar array. The hole solar array has to be 30 m² tall, compound by 12 panels.
Out of these 12 pieces are 6 of it in a row. The rows are parallel in the hydraulic system.
I fixed the system in Trnsys as followed with one type 1b:
Number in series: 6
Collector area: 4.84 m²

The type doesn't provide the expected values.

So I tested some small projects. I found out, that the number in series doesn't have any impact to the useful gains. It doesn't matter, if I put the value to 1 or to 100.There is no different.
What's wrong?

On the other side I used 12 panels and connected them to an array. It worked well and the output seems to be ok.
Next I only used 1 panel with 30 m². The useful gains compared with gains out of 12 panels are 10-times more.
Which solution is the right one?

I use Trnsys 16 and I can't update it, because I got it just to do my exam.


Many thanks in advanced for your help.

Patrick
