To be cheap, they need to operate at multi-GW scale, have a long operating life, and good reliability.

Unless it is all used at the point of generation, and near enough at the time of generation (storing and transporting it is expensive energetically and in terms of capital assets, and risky), economies of scale apply. And domestic use isn't a good fit for "use it all now while the sun is shining".
