What pack are you using? If any pack with GregTech, I'm pretty sure the recipes are on hard mode by default. You should check the advanced solar panels config and see if there is something there to make it easier(which I'm almost sure there is).
Normal mode versus hard mode on the tier 2 solar panel (the first one introduced in the pack) only changes whether or not you need Irradiant Glass (the step that needs glowstone + refined uranium) instead of just Reinforced Glass. The
Normal mode recipe requires
2 UUM and
1 Iridium ingot. For the 8 EU/t solar panel.
More importantly: This is normal versus hard in the
Advanced Solar Panels recipes. Gregtech actually does
not change these at all.
The recipe got more expansive as 8 ASP were less expensive than 1 Hybrid (or whatever the 2nd tier was called) and produced the same amount of EU. Now it is slightly more expensive than 1 Hybrid.
Tbh this change is not much of a pain and makes perfect sense.
The Advanced Solar Panel produced 8 EU/t during day, 1 EU/t during night. The Hybrid produced 64 EU/t during the day, 8 EU/t during the night. I'm not aware of a point in time when they produced the same amount of energy, and I'm also not aware of a point in time where you could produce a Hybrid without an Advanced as a component in its construction
The tier 4 Ultimate Hybrid Solar Panel (Which produced 512 EU/t during the day) could be produced in either of two routes, one using a set of 8 hybrids, one using an advanced panel with a lot of iridium-based materials added on top. I could see some possible discrepancies in cost at this tier being maybe a concern, but it still doesn't really explain why the Advanced Solar Panel now requires UUM and iridium, and it doesn't explain why this is not configurable at all.
It's now cheaper and easier to set up water mills, which produce more steady output than the ASP. Hence my joke about them being changed to require platinum.
