I quite enjoy this mod, and the support for SE is nice, but it is also a little limited.

• You can't calculate solar for planets you haven't been to yet.
• The zone list contains a bunch of SE internal surfaces, like pyramids.
• There's no support for steam batteries as an accumulator option.

Broadly, I see why the selector is a list of surfaces rather than a list of SE Zones, because otherwise it's quite SE-dependent. That being said, a tickbox or mod setting to change this to display SE Zones over Factorio surfaces would be appreciated.

Meanwhile on the steam battery (electric boiler -> 500 degree steam in a tank -> steam turbine) front, this is an increasingly popular option to replace accumulators in SE, due to their vastly increased capacity handling the often very high day/night cycles on SE planets far better than accumulators. It would be nice if the mod could be extended to handle things like tanks/eboilers/steam turbines/water loss for a steam battery.

Sorry for the late reply, I stopped playing Factorio a long time ago.

1. When I looked into this, there was no way to get surface parameters from SE planets you had not visited. As I recall, there was an API call to SE to get planet parameters, but surprisingly it did not include solar power ratio. I even joined the SE Discord and asked for this to be implemented, but unfortunately they didn't.

2. This probably could have been easily fixed, but I never reached the end game content of SE, so I just didn't care.

3. Yes, I thought about it, but there are also solar collectors and various other ways to get steam, so I thought it would be incomplete to just implement steam batteries without those other things, so I decided to ignore it at the time.

If I finally get to release an updated version of this mod with new GUI, I may be adding this features later.
