    We were lucky to just get our system put in before the FIT was reduced and are very happy with it. It has paid for itself by now so in some ways I am reluctant to change a system unless it offers a real advantage.
    It comes down to the relative cost of the electricity you export versus the electricity you import. If it costs you more to import than to export then you have the potential to benefit from a battery. But if you got in early enough then I think you will be paid more for your exported electricity than it costs you to import it so a battery would be counterproductive.

    Not sure this is right - the large income from FiT for early adopters was for generation, not export. So reducing export would not make a difference to it. Or were there super-high rates for export back then as well, in addition to the super-high FiT rates for generation?

    Early adopters (installs prior to 31/7/12) get 3.82p/kWh for export, whilst those with install dates from 1/8/12 onwards, get 5.38p/kWh.

    Only place I can put this is in the loft, but I see this not advised. So this would be an issue for me. If they are happy to put it in the loft I would bite their hand off.

    Yep and yep.........

    I know I go on about Octopus a lot!!! :D

    But an option for early adopters on the old 3.82p could be to move their export to Octopus and get 5.5p per unit. (leave their generation FIT where it is)

    Although I doubt early adopters care too much about 1.5p extra per exported unit when they are rolling in huge sums of generation payments!! :rotfl:

    I think you're well ahead of the game here, so as far as I'm concerned keep going on. We're at the stage now where huge numbers of households have smart meters and I think it's only a matter of time where these time of use tarriffs become the norm, significantly changing the economics of green investments like solar panels and batteries.

    You have more chance of getting a Time of Use (TOU) tariff if you are not on a smart meter unless it is with your current supplier. The issue being that nearly all smart meters installed at present are SMET1 which are non transferable as a smart meter to a new provider. New providers will not swap it for one of their smart meters as it doesn't go toward their target for smart meter installation.

    So the bizarre fact is, if you don't have a smart meter installed and want a TOU tariff, the world is your oyster, if you do have one and want a tariff that is not with the installing provider, then hard luck.

    Keep going Zarch, I agree with Mmmmikey. keeping us informed is great.

    When I switch to octopus.... which will be in the next month or two, I will of course be using your link, you are doing us a great service here.

    The octopus website states that if you have smart meter other than what they can read, they will change it to enable time of use tariffs.

    I have my battery [not the EDF battery] in the loft and was not advised against this. I suppose a concern might be that lofts can get very hot and this would be bad for the battery; otherwise i cannot envisage any problem. A fair area of my roof is shaded by the solar panels so that may help keep the temperature down.

    Thank you! :j

    Correct. I had an EDF smart meter which Octopus couldn't use so they came and put their own in.

    Its all a bit daft really...... hopefully SMETS2 will sort all this out. But that is not without its challenges as Octopus CEO regularly blogs about.

    https://octopus.energy/blog/smart-meters-the-innovators-challenge/

    https://octopus.energy/blog/unblocking-second-generation-smart-meters/

    Simplest way I can describe the difference between SMETS1 and SMETS2 is

    SMETS1 - data goes directly over the air to provider
    SMETS2 - data goes over the air to central repository before passing on to the supplier.

    So all that needs to happen when you change supplier in SMETS2 is that the end data goes somewhere else.

    And why SMETS1 is a 1:1 relationship with your provider.

    But to make things more complicated, it appears that the implementation of SMETS2 is different in the south as it is in the north and use different central hubs.

    In the south I was told that SMETS2 continue to use mobile/cellular connections as per SMETS1..... whereas in the north they are using some form of radio and each SMETS2 is in effect a piggy back for other SMETS2...... so forming some sort of mesh network.

    I got all this from the engineer and the CEO of the install company that I had the pleasure of talking to. :D
