[TRNSYS-users] Solar radiation comparison

[Michał Klimas]

Dear All,

 

I'm having an issue with comparing tilted (45 deg) total solar radiation
with measurements. 

I have connected measured total horizontal radiation to Type16a, and taken
as an output Total horizontal radiation.

I have a significant difference in January (50%) , February (30%) and
December (40%).  Remaining months are ok.

 

I have verified the Solar shift time, Latitude and checked whether any
radiation occur during night - everything is fine.

 

Can anyone suggest any solution ?

 

 

kind regards

Michal Klimas
