Hello everyone,
Since December 8, 2020, our photovoltaic system has been connected to the meter. Now we need to submit our first meter reading. According to the meter, we have fed 891 kWh into the grid so far (today). How should this figure be interpreted? The weather has mostly been cloudy with a few partly sunny days.
Can anyone provide some insight or an assessment?
Edit: Assuming I am interpreting this correctly, the meter shows that as of today, 891 kWh have been fed into the grid, and 2 kWh have been drawn from the grid. This seems plausible since we do not live in the house yet and only use electricity for devices and a few LED lights.
Edit 2: Oh, and the system has a gross capacity of 9.8 kWp.

As already mentioned,
1.8.0 is the consumption meter and
2.8.0 is the feed-in meter.
If I understand correctly, with a metering concept from your utility provider, you can use both meters and utilize the photovoltaic system for both. Whether that makes sense is another question.
Currently, I have a green electricity tariff of 0.2292€/kWh, and a pure heat pump tariff would only be marginally cheaper, if at all, plus an additional monthly charge.
I only have the bidirectional meter, and my 9.9 kWp south-facing roof system generated 483 kWh in December, of which 358 kWh was fed into the grid. Where are you from? My 8.6 kWp south-facing roof in Nuremberg produced only 129 kWh in December. January is also looking weak so far with 83 kWh. The region is usually quite sunny, but this year the system is underperforming.

But this year something is off. So far this year, only 10 kWh generated (9.7 kWp) :-( The problem is the snow that stays on the roof for too long. By far the worst month so far.

I am near Dresden.
In January, I am almost on the same level as you. 🙂
[ATTACH alt="IMG_7692.PNG"]56284[/ATTACH]You were really lucky with December. If PVGIS gives you 300 kWh, you are doing extremely well.
So, it seems to be getting clearer. The solar technician also says that the consumption seems very high to him. It’s possible that the meter connections might have been swapped. They will check this tomorrow. However, the more likely reason for the extremely high consumption is that after the meter installation, we still used electric heating for the underfloor heating for a while—basically a temporary construction setup—because the heat pump could only be installed about two weeks later.
If that’s the case, then so be it. But at least we will know what happened.
