> Per MWh costs of residential solar are usually 2x per MWh costs of utility scale solar. Utility scale solar power plants buy and install solar panels at larger scale and cheaper.

The only problem with this comparison is the cost of the grid, which at least in the US will dwarf the savings from doing utility scale installs.

One nice thing about residential solar is that it greatly reduces the need for transmission, while perhaps requiring some short-term enhancement on distribution. And ideally dumping a bunch of storage at grid distribution nodes in the form of a container of batteries would solve a ton of problems and reduce costs a lot. This is of course heavily resisted by utilities because in most places in the US they make their money on T&D costs, so cutting those is a threat to their existence.
