A domestic PV array in bright sunlight produces less than 4 kW,
only a
bit above a rapid boil kettle...

There's a big poster at my local Sainsbury's which says they generate
enough electricity to boil every kettle in the town. But not
simultaneously I suspect!

Greenwash...

Not the only example, they also say they are using LED lights in their
(semi-underground) car park to save energy, but it's obvious they are
fluorescents.

if they are that proud of their solar PV why don't they
have a big meter showing the total store consumption and what
percentage of that is coming from the PV, both instantaneous and
averaged over lets say a week.
