We've known for a long time that Tesla has been significantly underperforming in the residential (domestic) storage segment. The approx 2020 number was identifiable, and now we have confirmation that the annual volume can barely have accelerated since then. So likely that at best the annual run rate is approx 150k Powerwalls/yr at present. So about 1.5GWh/yr going into Tesla Powerwall in 2023. Here is an old forecast I did based upon what I knew the demand growth was doing back then - the scale of the lost opportunity is instructive.

And here is my understanding of global cell consumption for a comparison. As you can see the Tesla performance does not reflect a lack of demand in the total global stationary storage sector, and about 1/3 of that is domestic scale storage. So domestic scale global product is 10-15GWh/yr at present depending on whether using 2022 (actual) or 2023 (fcast). So Tesla is now down to about a 10% market share in global residential (domestic) stationary storage. Five years ago Tesla's global market share in that segment was well over 50%, and may have peaked at 68-70% or so.

Before anyone quibbles about "lack of cells" or "lack of power electronics" it is worth pondering that the other manufacturers got their components & cells from somewhere. In essence this is a market that Tesla - and the entire western world - has almost entirely ceded to Chinese manufacturers even if the result gets badged.
This was not due to a shortage of capital or cash in Tesla. It was a prioritisation of mental effort issue, and an inability to manage organisational bandwidth. Whether you consider that to be a failure of leadership, or a sign of good leadership, depends on whether you are a glass half full or a glass half empty person. Clearly Tesla pretty much chose to give up in this segment. I am not convinced that the parallel recovery effort in utility scale storage segment will succeed - I suspect that will be a case of too little/too late.
(Of course I hope I am wrong.)
