Azimuth Calculation problem


Recommended Posts


While calculating the Azimuth angle, we faced a problem, in fact we applied the rules we found in the help documentation (PVsyst 7 Solar Geometry) to calculate the Azimuth, and  at 7:00 am but the value was not correct.

We also share with you the coordinataes of the location 

lat = 33.61
lon = -114.58
tilt = 30
Azimut = 0
yr = 2000
albedo = 0.2

Kindley share with us what is the possible issue that made the 7:00 am value wrong.

You can find attached our results (in yellow) and the results generated by PVsyst.

Thank you in advance,

Best regards

Hello Michele, 

Thank you for your answer, 

We want to clarify that the file we are using file with 30 minutes time stamp (you can find attatched the data we are using), so we are wondering if the values have a connection with the sunrise?

Best regards,
