When to do the washing?

(Sorry - more PV plugging.)
About now.  Gone is the "Monday is washing day.", I wash either when I have load &/or when the sun indicates I can do it without access to the Grid for power. 

You can see the Sun gave me enough to do the Washing and push a little into the Grid whilst, at the same time topping up the Battery.

The extra is either the washing machine, the Kettle, or both; heating the percolator on Gas, of course, won't show.
:¬) 
Must try and get one where I boil the Kettle a few times?
