Sunlight hour analysis for defined analysis period failing


I know this is trivial but i can’t seem to debug this issue… I want to run a sunlight hours on a time period from 4/1 until 9/30 and from 10/1 to 3/30.

For some reason, my radiation analysis is working for that time period but the sunlight hours analysis is giving 0 hours.

Can someone tell me why or how to fix? File attached.

Thank you in advance, (617.8 KB)

Hallo @talalam,

you have to correct the surface direction of the “test Surface for sunlight hours”, it works afterwards.


awesome thank you so much… was clearly burnt out when i posted this :sweat_smile:
