I've just had solar and am moving to octopus. I'm hoping to get Intelligent (10p overnight) and Outgoing (15p export) or possibly Outgoing Agile (8-30p).
Presumably this is basic maths at this point. Is there any reason to charge the car with Solar over charging overnight at 10p and exporting the excess at 15p? I have 5kw of panels and 10kwh of batteries on a hybrid inverter.
