Hi, love the mod and it's bringing a ton of atmosphere (hehe) to my playthrough.
I just wanted to let you know though, that Space Exploration has its own solar power coefficients depending on the planet. But this mod overrides them, not taking their set % into account (so every planet and even space has 100M unless there is pollution).
For now I have turned the solar occlusion of this mod off, and that fixes it. I just wanted to let you know, for maybe you can find a way to apply your coefficient on top of any existing attributes instead of overwriting them. But if not, just disabling the feature works fine.
Thanks for the mod!

Do you have a save file you can provide for me to reproduce with? I won't have the time for an SE playthrough, so I'm not at the point where I could see how it behaves across multiple planets. For now, I can ensure that setting isn't possible when SE is present, but I'd like it to work with it too.

My save has a crapton of mods so that's not the most accessible thing (unless you don't mind downloading them all). But if you go into a SE game, enter the editor, launch a satellite until you see the orbit surface, you'll see a few solar panels there already pre-built. And then you'll see that those solar panels in space are not modified by the SE bonus (which would be +440% or something). If you then turn off the Pollution impact on solar in your mod settings, the solar panels will then go back to the SE behaviour.

Ah, good tip, can I also use that to check other planets?

I think you'll have to visit the planet personally to place solar panels on them even with the editor. Which is not the worst thing ever, you can use the editor to put everything in the cargo rocket, then go there. Once you have a save file with a few planets it should be easy enough to test?
