    Year end figures:

    Generated 6,990kWh (801.15 O's) 96% of target. [Estimate 98.5% of target if battery charging losses are excluded.]
    Imported 5,831kWh.  [All cheap rate apart from ~0.5kWh/day that sneaks through.*]
    Exported 4,166kWh.
    Total consumption 8,655kWh.   [That's all household demand, but excludes some BEV charging away from home, which I'll guestimate at ~300kWh.]
    Gas from Jan to late Oct 655kWh.

    *Day rate leccy imports due to three factors. First and smallest, the battery inverter not being able to react perfectly to demand increases. Secondly, not being able to match varying demand from microwave and induction hobs which don't sit at 100%, but phase between 0% and 200%. Thirdly, once we replaced the gas oven in Oct, it, plus any other demand on at the same time, can exceed the inverter limit of 3.68kW. But all in all, I think ~0.5kWh/day is excellent.


    Edit - Estimated leccy bill for the next year, at current rates, is ~£550. Estimated export income, at current rates, is ~£550 to £600. Nice. 
    Hi Mart, Impressive figures there especially now having used no gas since October and in combination with only leaking circa 0.5 kWh's to day rate at this time of year when it's most likely to be worst case. 
    The Octopus Export rate is a nice bonus for us all to enjoy too while it lasts.

    Year end figs here are:
    Generated 9875 kWh's. (Solaredge figure 10,020 so 145 kWh's optimistic!)
    Imported   13503 kWh's (Of which 287 hrs at day rate)
    Exported   11570 kWh's
     
    Consumption 11808 kWh's which includes EV's 2895 kWh's.
    Charging away from home 845 kWh's.

    So total consumption 11808 + 845 = 12653. Thus almost 3 MWh's shy of being theoretically self sufficient energy wise! 
    IF, and it's a big IF planning permission is granted for our proposed solar carport then we may just get a little closer to being so come the end of '26.
