Newbie here, hello everyone!
I have a problem / query / concern!
We had solar panels and two batteries installed in March 2019.
On 22nd November, we had Smart Meters installed for electricity & gas.
Since then, our electricity usage has rocketed and I do not believe it’s a coincidence.
The last few months in detail:
Oct to Nov = 47 kWh (clocks go back)
3rd Nov to 22nd Nov = -(minus)2 kWh!!
22nd Nov to 3rd Dec = 106 kWh!! (smart meter installed on 22nd)
4th Dec to 3rd Jan = 305 kWh!!
I appreciate you will use more electricity in the winter but this seems suspiciously high.
I have tweeted OVO and done the creep test as recommended; I didn’t find any issues.
We haven’t had any new appliances and our daily routine has not changed.
I have contacted our PV installer and they will be coming round to check everything.
Can anyone provide an insight as to how much power they use from the grid, on average, throughout the darker days of the year?

These are my usage figures for the same period that you quote, I am an EV driver so have subtracted the usage that was for chargng the car. I also have a 2.82kWh PV system
July 75 (good generation month)
Your figures pre-smart meters look a bit unrealistic, unless you have a massive PV system; mine is 2.82kWh and I tend to use between 10 to 15 kWh per day without charging the car and without too much PV generation, however, I don’t have a battery. Do you charge the batteries on an E7 rate at night then use the batteries during the day?
Are you able to split usage, for example usage by month together with total PV generated, that data on PV would help as would any data of how much you had put into the batteries.
Average UK domestic usage figures per annum are here:
- Low consumption is estimated as being between 1,900kWh and 2,500kWh
- Medium consumption at 3,100kWh to 4,200kWh
- High consumption is between 4,600kWh and 7,100kWh.
My PV system generates between 2000 and 2500kWh per annum.
Hope all this gives you food for thought!
Just thought of something to try, on a good solar day does your IHD show negative consumption?
