For some reason Flat Solar Panels adjusts the recipe for the new tiers introduced by Advanced Solar, and changes the recipes for the advanced normal panels to require Flat Solar Panels instead.

How so? It shouldn't change any existing recipes. It adds two recipes, though. One that makes a flat solar from a regular panel, and one that upgrades from a previous tier flat solar. The original recipe should still also be there.

When I install Flat Solar Panels with the Advanced Solar installed, the recipe changes.

Edit: The recipes for the "regular" advanced solar panels are being set to the "2nd" flat panel recipe, the one that requires 5x previous level of flat panels.

Hm. Thanks. I think I know what's going on. I'll put up a fix in a bit.

Just uploaded a fix for that.

Looks good to me, thank you very much!
