I humbly request you to add a 5th tier of solar panels and accumulators, and that you make them orange.

Because then, we could fully color-coordinate tiers with rarity.
Common - T1
Uncommon - T2, both green
Rare - T3, both blue
Epic - T4, both purple
Legendary - the T5 i am asking for, both orange

That's a neat coincidence considering the colors are like that for a few years now.
I might consider adding another tier. But it might be too OP even for my taste. Each their own I guess and that's why you can disable tiers.
I might consider only enabling this tier if you have the quality mod enabled. But legendary T5 panels might be way too OP :D

Any name suggestions what might come after ultimate?

Im not sure about that "too OP" thing, legendary T5 (or any T5s really) will be expensive
For the name... I thought about something like "perfect" "(grand?) master" or "mythical", but i think i have a better solution:
If you lock T5 behind Cryogenic Science, you could go with a "supercooled theme". Like, IRL all our superconductors only work at really low temperatures, so it could be called like "Supercooled Solar Panels/Accumulators", and let them only be crafted on Aquilo.
I also considered "Promethium Panels", but then i realized that using promethium in anything other than it's science is kinda not worth it and upcycling promethium for legendary panels also sounds like a big nope.

Edit: Wait that theme only works if Space Age is enabled. Uh. Maybe something more generic after all?

Hi, just wanted to ask if you are gonna do this or not. I also have some additional name suggestions:
1: Flat out call it T5 Panel
2: Name it something silly, like "Cookie Solar Panel"
3: Name it after someone, maybe yourself. "LsHallo's Solar Panel/Accumulator"
4: Can you change the name the player sees without changing the internal name? If you can change the visible name without messing up saves, you could move "Ultimate" to T5 and add another name somewhere on T2 - T4.

I like the idea of an optional T5 panel/accumulator, but I like the idea to shift the names as the 4th point as "ultimate" is the superlative and should be the last tier. I would not call them like "perfect"(so the others are not perfect?) or "mythical" (sounds more like a rarity). Even if I like the idea of "supercooled" or something similar sounds good to me, it wouldn't fit the others well. How about an "updated"/"upgraded" T2 (I'm not convinced about these specific names either)?
I support the idea to use Aquilo materials/tech for the T5 then, but I see that in non-SA-cases, this is... less of an option.

I had some fun with a potential 5th tier and finally found a color combination that could work for all 5 tiers.
I'm currently calling it the cryo panel and accu similar to the science pack. Probably needs cold fluoroketone to craft. (Open to suggestions)
The 5th tier would simply only be enabled with space age. I cant think of exotic materials to use in vanilla that would justify the capacity.
Maybe take a look at the whole lot and tell me what you think?

I like that the 5th tier is only a SA-thing then. Cold flourkentone as ingredient sounds to me fine if the hot flourkentone is also a byproduct. I'd suggest it is a EM-plant recipe as it has already all the piping needed.

I like the colour scheme in general, but I suggest a stronger contrast between T1 and T5 as well as between T2 and T5. I understand that it is not easy to have them all great at once. Cyan as colour indicator sounds great on paper, but how about something darker? Maybe something like dark grey or even black?
EDIT: or maybe even orange as the OP suggested.

Crazy Idea: The cryo panels need cold fluoroketone and work a bit like a fusion reactor.

I don't think that is a good idea. Solar panels are a "place and forget" energy source with minimal UPS cost, too.
If they work similar to a fusion reactor, why not building one directly?

Yeah, just calling it "Cryo Panel / Accu" and making it Space Age only is probably fair, and it needing cold Fluoro to craft sounds good. But i agree with OC1024: Needing Fluoro to run does not sound like a good idea to me.

As for the colours, i dont really care. I suggested orange due to the Tier/Quality similarity, but the making it could fluoro coloured is a nice touch. I do not think dark gray/black would work well.

I know im late to the party here but you could add that 5th tier and make it a .1% increase vs T4 with just a higher quality modifier to a different space modifier? Ultimately its unlikely it would be more powerful then the current end game Fusion generators that do 150MW

I don't really get what you mean with quality to space modifier?

Sorry I let this slip again. Wasn't really satisfied with the colors and set it aside again. Real hard to make them distinguishable without being super obnoxious.
After second thought requiring a fluid is more hassle than it's worth although panels that could generate more than a fusion reactor might need it for balancing ;) But that's the neat part: Everyone can choose how to play and what tiers to disable.

Expect some movement in this direction in the coming weeks for 0.8.0 release of my mod.
Maybe even with float modifier values so people can set stock panels to 0.5 and go from there. (although this will be a nightmare with SE2 compatibility or similar mods that touch default panels)

Hm, I see that T5 is very powerful but the cost scaling are there, so it is not just OP. That float modifier could be an option.
As a fellow mod author, I offer you my help with that compatibility cases (and in general). You can add me in discord if you want.
