I mean it is FTB compatible it's just not big and fancy like GregTech or advanced solars which I plan on making it.
If you'd like to see what I'm talking about basically right now you don't need IC2/GregTech. But in the future I will make it so that you do need it.
Check the link in my description (the Dropbox one and go to the "Solar Recipes.doc")
Enjoy
Also thanks for the help on testing. If you'd like to help TREMENDOUSLY then you could take pictures of when you craft the items too
Also, could you wait a little? I'm going to get v0.0.3 out later tonight with some big changes so yea
