Cost, resources availability, and fluctuations in supply.
my energy bill right now is like a new solar panel a month. what resources do we not have, and are you familiar with pumped storage? spoilers, we already have renewable stable energy supply
The truth is, we do have enough resources. We just care more about the economy and profit than our future climate (which will also strongly affect the economy, but that's in the future so...).
If we actually valued the climate as much as we ought to, switching fully to renewables would be a bargain.
We dont' really care about the economy, otherwise we wouldn't be doing this boom-bust shit and we'd have a better planned economy that would ensure there wasn't a perpetual under-class of starving people in every industrialized nation.
Our Government DO care about making sure their donors get paid though.
Everything has a cost of course, building solar panel requires a significant amount of precious metals, which may or may not be easily accessible or affordable depending on the political climate between countries who mine vs the countries who needs the resources.
And the production of solar panel does create some toxic leftovers which needs to make handled appropriately. Not saying they're a bad alternative and they're definitely before than fossil fuel or coal, just needs to consider the cost and the impact of everything.
Mmm, no, no they dont. Solar panels are primarily made from silicon. Sand.
They also need
and some others rare-earth elements, as well as some platinum-group metals. The current photocell chemistry we use is quite complex.

and even then, solar panels are only one part of the whole system, since the source of energy fluctuates significantly.
solar panels do not use these metals you are worried about
