Radiation calculation

Subject: Radiation calculation

Hi all,

Why TRNSYS is not calculating correctly the radiation on West wall?
It is always very low in the afternoons as compared to morning radiation on
East wall.

Is there any error in the Deck? I shall be grateful for help on this matter.
The deck is attached along with one week's input data for New Delhi (India).
Also enclosed are 2 output files.

New Delhi: Longitude 77.2 Deg E, Latitude 28.6 Deg N
Standard meridian is 82.5 Deg East
Thanks
