So how is that going to work; (a) I have solar panels (b) I have a solar battery storage (c) I have several choice of tariffs with Octopus energy, Octopus Go, ECO7 and Agile ?
Having several choice of providers tariffs doesn’t matter here and now, but it will probably in the near future, when BEV’s become the main car of choice and the grid starts to hit high demand., A surcharge or higher unit price on charging will apply – part of the point of a smart charge point. Remember we have been offered a sweetner to dip are toes in EV’s – The government have removed part of that sweetner and will soon remove another taxing EV’s eith by VED or the smart charger. How long before these tariffs are removed, or should I say when EV’s become more main streem.
You have what might be an interesting solution, with solar and battery storage, that will probably work or soften the impact, but I’d assume bigger battery storage and sunny days will be required. Even so, if all the sweetners are removed your current system will go some way when EVs become the norm.
