I assume these are all MW-peak on the solar side, which means the sustained average capacity over a day is 20% of it? While the coal plant manages 4x660MW 24/7 outside maintenance windows?

That's not including the manufacture of the PV and extraction of components to make it, or shipping times, etc, is it?

No. That's all done in a factory off-site, so I didn't consider it as part of the deployment. I'd argue that scaling a (centralised) factory is easier that scaling deployment.
According to Google 178 GW of solar modules was produced in 2020, which is 487 MW/day and capacity is growing exponentially, so production of modules probably won't be a bottleneck going forward.

They have a system whereby a solar array is concertinaed off a truck.

At that rate 4 x 660 MW, equivalent to a coal power station, could be deployed in 66 person-years. 130 people could not build a coal power station with 4 large generating sets in 6 months.
Suncable is expecting to complete the Australia-Asia Power Link by the end of 2028, starting construction in mid-2023. It will involve installing 3.2GW in 5.5 years, which is a rate of 1.5 to 1.6 MW/day.
