(Not my field. The following is armchair speculation.)
TLDR — It’s not. For distributed/residential, bulk power generation, and light-duty transportation, solar has already won so decisively that fusion is not likely to catch up this century. But those aren’t usually the target applications.
TMK, Fusion offers most of the known advantages of fission (smaller footprint, superior energy density + capacity, output that’s weather-independent and geography-agnostic, etc.) but with significantly better safety and waste profiles.
Its versatility as a thermal source enables many industrial applications requiring temperatures difficult or impossible to achieve via electrification alone.
The reaction itself is directly applicable to neutron production.
There’s some even more far flung applications like outer planetary and deepspace space travel.
And others. All to say, it’s for niche and future applications PV can’t touch.
That's fair. I guess if you really need a spicy blowtorch...
