I am trying to create a solar position routines using Dynamo 1.3.1. I am successfully getting results from Dynamo but have sense checked them to ensure that they are accurate. Unfortunately, when comparing these values to the US National Oceanic & Atmospheric Administration (NOAA) and US National Renewal Energy Laboratory (NREL) solar positioning figures, there are large discrepancies. Both NOAA & NREL agree closely with each other. Attached are screenshots of the necessary information that highlights the differences between Dynamo & NOAA’s values.
