    Percentage wise,it depends what is called “nicely profitable”,but in business,I wouldn’t call it that.In fact it’s quite a long way off.Then there was the added cost of the upgrade.

    The battery will also deteriorate over time,possibly have reduced capacity, and need replacing,but who knows when that will be.

    Tesla guarantee 80% in 8 years for cars but I don't know about Powerwalls.
    One thing Tesla is good at is battery design , control and most important cooling.

    Oh well, profitable, nicely profitable, it seems their case for justifying it is still sound. From a household perspective however it seems that batterys are not profitable. Batterys I think are typically warranted for 10 years and I can only assume the SA Tesla battery would be at least that. Assumptions hey, right! But all of that information is fairly predicatable.

    I understood the Tesla powerwall has a 10 year warranty. Sadly they wont pay for themselves domestically.
