Sun Azimuth/Altitude Data in Ladybug

JI · February 16, 2021, 7:35pm

Hi all,

When I was using Ladybug for getting hourly sun azimuths/altitude for the entire year, some values are missing.
Ideally, when the sun is down, the value needs to be 0. For now, it only has 4408 values when the sun is on during the daytime.

I was wondering if any tutorial could help solve this problem?
