Where to find and how to add solar analysis script

I am new to dynamo, where to find script for solar analysis and how to load in dynamo. Thanks

Hi, this is very little information to go on, unfortunately, but check out the Ladybug-package and the github page here: https://github.com/ladybug-analysis-tools/ladybug-dynamo

There is also an interesting video called UNIT 6: SOLAR ORIENTATION on the learn page:
