Solar already hit a supply shock this year that has increased the cost of installation (it has been reliably going down before this). Solar growth is expected to be closer to just linear this year. I hope this is temporary due to all the supply shocks going on right now.

Looking longer-term there will be growth slow-down when wind/solar reaches a larger scale due to the intermittent nature of the energy unless we can figure out how to deal with this. Currently dealing with it requires lots of gas peaker plants, hydro (which has its own environmental damages) or batteries (the resources required to produce and continually replace these are not sustainable but hopefully the net carbon emission can stay low). Malaysia recently had to stop incentivizing solar because their grid couldn't handle it.
