Re: November 2022 Generation
I do have a few advantages, I’m in the south, 51°and I have room for ground array. However it may well still be a stretch and currently I don’t have an EV or electric heating.Joeboy wrote: ↑Thu Dec 01, 2022 5:09 pmDepending on the latitude you may be on a hiding to nothing with that goal.

Being quite far North myself I have found that absolutely minimising the load drawn at home is akin to having another few panels operating at this time of year. Even on the scabbiest day the batteries get a tickle. Insulate, insulate, insulate sure but also do multiple wall of death runs around the house with a wattmeter and clipboard too.
The results may be surprising?
Re: November 2022 Generation
Absolutely, I try and push the load reduction as much as the shiny stuff. Not as much fun but when there's only a couple of hundred Watts coming in and a few are still heading to the battery, a nice feeling! I look forward to seeing it play out.Jinx wrote: ↑Thu Dec 01, 2022 5:24 pmI do have a few advantages, I’m in the south, 51°and I have room for ground array.

Re: November 2022 Generation
Since we bought this plot of land in 2012 it's only snowed once. We had about an inch of snow overnight once, lasted until about lunchtime before it melted!

Re: November 2022 Generation
Nowty Towers Power Station
Main 4kW PV system generated 166 kWh which is about 8% higher than baseline.
Total PV arrays generated 315 kWh.
Electric Import was 1595 kWh.
Gas import was 23 kWh.
Out of house EV charging was 0 kWh.
Petrol used in EV hybrid was 0 litres or 0 kWh.
Total imported energy use 1618 kWh
Electric export was 10 kWh.
WT1 generated 841 kWh.
Total energy offset 851 kWh
Net energy for Nowty Towers > 767 kWh
Not negative anymore, but if WT2 was operational it probably still would be.

Re: November 2022 Generation
Our total grid import for November was 412.51kWh
PV generation = 243kW
Total energy consumption (house and car charging) came to 655.5kWh
Out of that total energy consumption, the car used about 106kWh, so the house used about 549.5kWh, or around 18.3kWh per day.
Most of that will have been used by the hot water (around 4.5kWh/day) and the 24/7 consumption of the treatment plant, MVHR and UV disinfection unit (total about 3kWh/day). That leaves around 10.8kWh per day for heating, cooking, lighting, running PCs, running the washing machine and dishwasher, etc.
At a rough guess, I think heating this month used an average of about 4.5kWh/day. We had a few days with no heating at all, but also a fair few days where the heating used close to 6kWh/day. That's mostly because we like to try and keep the whole house at around 21.5°C to 22°C, plus I seriously overcooked it a few days ago by running the heating during the day off the batteries. We had a day when the temperature was close to 23°C because of that little experiment.
Over the whole year we tend to average around 12kWh/m²/year for heating, so the expected total heating energy spread across the year should average out at about 4.27kWh/day, but that's compressed into about 5 months, so more realistically it comes out at about 10.25kWh/day through the winter months, so we are probably pretty much on track for a normal, or perhaps slightly lower than normal, year.

There's around 12 degrees of separation between him and us which is as they say 'a fair skite'. Not sure if that's the forum max or not? Who's in Austria and at what Lat, same for up North, who's up there?

Re: November 2022 Generation
I'm in Austria at 47.4491382 latitude, though I don't have any generation here. Mine is at 54.8, 107 kW from a 3.75kW system (approx, don't really have access to reliable accurate data without inconveniencing others so tend to leave that for FIT reading time)
Living the dream in Austria.
