Not a direct answer to this question but you can use Ladybug and Honeybee for solar studies. It will give you more control on inputs and outputs. There is an example file for Radiation that comes with installation package.
NOTE: You need to install Radiance to use Honeybee.
Hi @EKAS88, I didn’t get a chance to record any for Honeybee but this playlist should be a good place to get started and understand the workflows. If you are already using Ladybug Tools with Grasshopper you already it’s pretty much the same.
