Connecting Grasshopper with Ecotect. Questions.

Hello everybody, I hope I can find some help here.

My GH skills are pretty much basic, but I roughly know my way around. I've been trying to find a way to link my gh work with Ecotect. I'm making some research involving shades and and solar radiation and I need the sun's path through the entire year to fully optimize the design. This far I've been able to simulate what I want by having my shadders following a mock solar orbit around them, what I need to know is to use a model that simulates solar paths, use it as an attractor point and have my shadding surfaces follow it, pretty much like that I am doing right now (or so I think)

Here's where my questions come around:

I remember finding somewhere on the internet a definiton that simulates the sun's path through the year; I think I can find it again and use it for my purposes. I think that I could just run the GH definition, bake the geometry and then upload it to Ecotect and have it run so I can get the data and keep working over that, then feed the geometry again to Ecotect, ad nauseam. However I think that is a very slow process.

Is there a way that I can run an Ecotect plug in of sorts within GH, that way I can get my data IN grasshopper and model accordingly?

Does that make sense?

Thanks a lot for any input.
