As SeniLiX said, the OPs problem was solved after someone told him that advanced solars was installed, instead of Compact Solars. AND when he disabled teh GregTech recipes, it didn't do anything. The logical assumption is that he had merely mistaken the Advanced Solars recipe for a GregTech recipe. He was corrected, the problem was fixed, and he seems to have gotten his answer. Can we call this thread solved, now, and let it fade into the older pages?
