That’s a very expensive solution. Try as I might (and I’ve been guilty of some classic man maths over the years) I just can’t press the button on a powerwall. The payback just isn’t there until either all suppliers are charging peak rate prices (the likely end game for smart meters) or battery prices half again. Even a smaller system like Enphase (1.2kWh modules) that I could self install cost £1500 and would save best case 1.2kWh x 35p x 365 days = £153 per year. Even with zero % loans from the energy saving trust, it doesn’t add upA Powerwall cures the 4-7pm highspot.
Completely agree. The sums just don't add up. Electricity prices would have to rise astronomically to make it pay for itself.
I know but I’ve got two and my God, it makes you feel smug.
I think now I know how vegans feel
Powerwalls seem to be verging on unattainable and TEsla just put the prices up (in the US at least)
I was hoping battery day would result in cheaper and more plentiful powerwalls - The answer appeared to be yes, but not yet i.e. come back in 2022
