Just noticed that the solar panel recipe disappeared with the new update, dont see it in the changelog and wanna make sure its intentional

Yes that is (forgot to include it in the changelog) as in FFF399 they give us the EM Plant recipes, solar panels are not mentioned. I will likely add them back as a startup option, off by default as it just makes sense, but as of right now I only have the confirmed recipes in

It's possible that in the expansion they won't be made at the EM Plant but rather a different equivalent machine on one of the planets they haven't showcased yet, but I agree that it would just make sense for both solars and accumulators.

Readded as a startup option
