On busy days at Morrisons (or Tesco) there may well be 10 or so cars

A pump is occupied for a few minutes, say 5 once payment is included.
You want to crank that up to 30. So you'll need 6 times as many
charging points as pumps, to service the demand. So 60 charging points
at, as someone upthread (IIRC) mentioned, 6MW each. You're asking the
grid to supply 350MW or so to every supermarket. You really think
that's practical?

Extremely efficient solar panels are what's needed.

What do you mean by "Extremely efficient solar panels"?

400% efficient would be handy
