Subject: [TRNSYS-users] Zenith angle/Problem with meteonorm indian weatherfile
Hello,
I would like to pick up a subject already metioned on 7.July 2010
concercing the incidence angle.
Comparing Type 109 with Type 15 for a TMY2-file I noticed some
differences in the zenith anlge especially near sunrise and sunset.
When the sun is down Type 109 is 99° (??) while Type 15 ist nearly
(approx. 2-3 degrees lower) than 90°. But why?
Is there any Trnsys convention on the definition of the zenith angle
during the night?
I have another problem concerning indian weatherfiles. Calculating the
solar radiation for vertical facades on the east and west I got very
different and strange results. Does anybody know about a similiar
problem?
Thank you, Stefan
