Standard tariff.
I bet not everyone is on a computer eV tariff
My buddy was complaining to me last night that his Tesla Model Y will cost more to charge at home than my petrol car does to fill up.
The Model Y has a 75kWh (I think) battery. Even at the October price cap that's about £39 to "fill up". The same cost as 23 litres of unleaded.
) had a solar panel on the spoiler as well, but I think it was basically just used to maintain the 12v battery
