    2-3 years from now a more affordable model will be available. It just needs two Gigafactories completed. One for the batteries and one for that car. Both are being built right now.

    Will be slightly less astounding though.

    I would love to have one fitted, but the 1st time it failed or played up when i was back in the UK it would get ruined whilst trying to be repaired by FiL, mrs brother or any of the local so called sparkies that work round here.
    I rewired our house myself and the MiL's now most the local electricians wont go near them when I'm back in the UK working because they don't understand it???

    Too much cloud cover to work efficiently all year long. It really needs large battery storage which is still expensive. Prices keep dropping though fortunately. New storage systens coming.

    Good idea

    Not nice. They sell the package and then mention, oh, you need this for it to work and since you already gave your credit card you are forced to buy

    My bill hits over 10k at times. And I am environmentally aware, try save energy, LED lights everywhere. It's the aircon, all units now less than 2 year old but so many of them

    It's the A/C pumping up the cost but that is price one must pay for living in the tropics and have a very nice life style.
    As long as one can afford it who cares.
    Exactly.
    And this isn't Perth.

    I think I'll just wait for that. Then make my move. But I like this idea anyways, good thread.

    The concept does not necessarily call for solar panels on the roof. Usually the Powerwall would be connected to a grid. Solar panels wherever they are feed into the grid and the batteries everywhere, plenty of them, will be charged when there is a surplus in the grid and feed the house when power in the grid is scarce. Depending on the contract the batteries may even feed back into the grid to mitigate power peaks. Car batteries may contribute to the buffer function.

    Supplying power to houses off the grid is only a minor side use.

    ^ If you are talking about a national power grid, there is almost always a "surplus" in the grid.

    Yes, it has to be for a stable grid and it costs a lot to maintain that. There are always fast responding power plants on standby to make sure. The batteries can do that instead if there are enough of them some time in the future and they have the ability to absorb excess solar and wind energy too. Presently solar and wind farms are forced offline when there is excess.

    But to be really economical and support the grid batteries still need to come down a lot in price. With increased and efficient production prices are coming down fortunately.

    OK Guys, nice discussion, but does anyone have any real time suppliers of Solar power kits that are cost effective. To my mind they must include enough panels to supply power for a few air conds, an inverter, and should have some sort of battery back up. What would we need to pay for such a set up???
