Dan,

You can set the altitude with the location.altitude parameter (in units of meter above sea level)

Anandhaprabu,

Don't forget to set your UTC time difference (time.UTC).

Hi, I have a quick question. Is there a way to use this function in reverse? I have a known lat/lon position, the year, the day, and the 3 solar elevation angles. Based on those givens, I am trying to determine the time of day. Is that possible with this?
Thanks!
Andy

Hi Nasir,
I (= Jeroen) am just a user of this sun_position function, perhaps your question is meant for Vincent Roy (=author of sun_position).
Still, I'd be glad to help if I can.

Can you post the code that generates your error message ?
