I tried using the data from Meteonorm for Madrid using Type89d (TMY2
standard), and then, connecting it with Type16i. Changing the time
shift from -14 to -16 did not make much difference. When I compared
with the results from reading the data with Type109, I get the same results.
In the previous email, looked like using a time-shift of -16 you got the
same results. I think that the difference at sunrise might be due to
rounding error when the difference between solar angle and sunrise angle
is calculated in Type109.
I agree with you that the shift should be -16°. Zaragoza, Spain:
Long.= 1°West , LSM=15° East (UTC+1), Shift=-15°-1°= -16°
If you still have problems, I will be happy to help you. Please send me
the project file and the weather data and I could take a look at it.
