If there are ever enough domestic PV panels to avoid building

But AIUI that can never happen in the UK since peak demand is on winter
evenings.

I don't have an figures to hand but ISTR that total demand peaks during
the day when most workers are hard at work rather than generating
tea-break spikes when their favourite TV programs end.

Seems to be about 1700...

Seems I was wrong.

Site took an age to load but contains interesting information about
current circumstances. The System demand curve is a weird shape. Down to
little more than half peak demand in the early hours (approx 4am) which
is only to be expected but daytime demand is virtually on a plateau from
9am to 4pm at 87% of peak with a sharp peak above 87% between 4 and 8pm,
by which time demand is falling steeply. I wonder what factors cause
that peak.

Millions of microwave ovens and kettles making TV meals. Fan heaters
warming up cold rooms after a day of being empty, before the central
heating gets going properly.
