I have the impression that these two are good to put in the cave ...

In this regard, I hope that the entrance is closed, (for children).

Otherwise rather think about making a sun supplement,

But at such an altitude there must be quite a bit of wind :!: no?
In this case a wind turbine would be very useful. It is cheaper than photovoltaics.
Do not neglect either the fact that there may be an underground river in this cave ... (possibility of making electricity)
