We're getting a bigger solar battery installed next week! So lots of tidying up the porch, making sure we have tea and biscuits on hand, and researching whether we can move to a dynamic electricity tariff.

And hoping next week is sunnier so we can fill the damned thing!

The answer is... I don't know :-) Maybe both? What do you think would be best?

I have a (very low) fixed tariff with them, but I'll move to agile when it ends.
