I see your point, but eventually the solar panels produce the energy to produce more solar panels. Including the mining

IIRC there is a formal guidance for what is classified as renewable. Things like oil, while originating from biological matter, obviously being considered 'not', while tree mass, plant mass, being considered so. Believe the guidance was whether the carbon emitted in its production has been or could be absorbed within a lifetime, via the means with which it was produced.

I have reservations with nuclear but I imagine it would fit within those guidelines easily.
