How low can you go...Daily, Weekly, Monthly, Whatever... electricity grid import

Spies

27.345kWh electric over the past week which is the least I've ever used,  also earned £23.95 in export over that same period.

August was a good month

History for 2021 here.

History for 2022:

• January 2022 - 219kWh imported, 84kWh generated, 17kWh exported.
• February - 169kWh imported, 142kWh generated, 51kWh exported.
• March - 146kWh imported, 246kWh generated, 99kWh exported.
• April - 132kWh imported, 300kWh generated, 179kWh exported.
• May - 106kWh imported, 335kWh generated, 171kWh exported.
• June - 40kWh imported, 338kWh generated, 114kWh exported.
• July - 50kWh imported, 341kWh generated, 100kWh exported.
  

August was another good month.

• August - 48kWh imported, 322kWh generated (118.3 O's, 116% of PVGIS), 183kWh exported (57% of generation).

We were away for ten beautiful sunny days during the month, hence the high export number. If we'd been at home we would have used more of it.

Import is 1.5kWh/day, but again we were away for a third of the month. For the days we were home, it's more like 2.4kWh/day. Most import was (again) off-peak with Go.

Self-consumption of 139kWh (4.5kWh/day) should really be 7kWh/day sonce we were only home for 21 days!

Compared to last August I've imported 14kWh less and have generated 59kWh more.

My latest Octopus Go statement shows August-ish consumption of ~55kWh off-peak and ~8kWh peak, for an average price of 6.3p/kWh.

Also of note, August was my seventh consecutive month of beating PVGIS

Magnitio

Figures for August:

• Generated 844 kWh (average 4.25 O's/day)
• Imported 92 kWh (£32.20 at 35p/kWh)
  
• Exported 717 kWh ( £273 at average rate of 38p/kWh)
• Consumed 171 kWh
  

Imported a lot more this month, mainly because import rates were lower than export.

Savings since installation on 1st Feb (7 months) is now over £1,100. This is more than I had estimated to save in the whole of the first year.

Another month well over PVGIS.. every month this year so far has exceeded predicted generation.

Relatively high import for me this month due to some very low generation forecasts triggering import at "go Faster" rate.  I could turn the Pi off in summer but its interesting (to me) to just let it get on with its job of deciding how much power I need to get through the day.  There is no adjustment for the difference in summer to winter daylight hours so no allowance for the sun hitting the panels earlier. 
Overall no real changes



Cannot seem to get the graph to show the month or scroll .. 

396 kWh Total used
17.45  kWh imported 
516  kWh generated 
129  kWh exported
4.8  kWh Highest daily import
0.0 kWh Lowest daily import... Actually had a couple of days with ZERO import

76 % of generation used... 

PVGIS 450
Best day 25.5 kWh
Worse day 5.9  kWh

Gas usage .. 1.5 m3

Managed to setup Home Assistant and it has made monitoring and tracking things a lot easier.  There is a few KW difference between what is reported from Home Assistant(from Givenergy) and E.ON Next.  My consumption does include iBoost 

August data is partial
Generated - 450
Consumption - 388 
Import - 28
Export - 86 

Trying to get the wife to stagger cooking or energy use is a work in progress

I imported 6.76kw from the grid in Aug.
That represented 1.02% of what I consumed, 98.98% was from solar.

I am not sure if this is an appropriate place to ask this question.  I do not have any self-generation but did monitor consumption while away in April.

Gas was zero, entirely as expected.

Electricity on leaving home 10th April = 48,563
Electricity on return home 24th April = 48,634

I make that 71 kWh over 15 days (include both days at each end as left very early and home late), so 4.75 kWh per day.
That is the clocks, heating controls, security lights, blinds, modem, smart home hub (Echo) etc.  More lights on time in April than now.

Is that amount of load typical, or do I need to look at reduction measures?

4.75 kWh per day. would be approx 200W.  I'd be pleased with that although my baseload includes a couple of air compressors (sewage treatment & pond aeration) as well as a permanently running PC.

I would be happy with that as well.. my baseload is almost double yours.. fridges, freezer, Router etc... even though the freezer is supposedly A+ rated it seems to use a lot of power particularly over the recent hot spell... Of course you can try to cut it even lower.. turn off things you don't need while away but as I said I would be happy with that
