Essentially, its a game of capital and solar is accessible to (almost) every human household on the planet.

Additionally, zeroish fuel costs/operational costs, grid connection is optional, capacity to build panels is not controlled technology, raw materials are relatively cheap. So scaling production further or bringing it online is not otherwise constrained.

Nuclear can still can be strategically important as rock solid base load and for grid stability.

In the future, with better understanding and control over nuclear physics, nuclear one day might be as cheap and plentiful as batteries, but for this cycle , solar has essentially ‘won’
