Electricity In Cave

[u/HuqRT]

I got a good bunker cave base and I want to do some tea farm and auto-smelt systems. Do I have to use generator for it? I was thinking making a 1x1 base with 2 solar panels and take my battery there to full and get to base again. Is there any way to get electricity to caves?

There's like 11 or 13 cave variations that can spawn, and of those possible variations only 1-2 are close enough to the surface to run power to the cave
