ᐅ Experiences with Photovoltaic System Performance?

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.

1.8.0 is always consumption

Hmm, does that mean we have consumed 891 kWh since 08.12.2020 and fed in 2 kWh? That can’t be right either.

I edited my last post again...
We used 900 kWh after the screed heating program. Has it been running the last few weeks?
Check the inverter to see how much you have produced so far! That might match up with the feed-in.

We have one meter for the heat pump and another for the household and photovoltaic system.
The screed was done around September/October.

I think this one is for the heat pump.

This one is for the photovoltaic system and household.

What do "high tariff delivery (001)" and "high tariff consumption (002)" mean?
I would assume "delivery" refers to what we have fed into the grid, and "consumption" is what we have purchased.

As already mentioned,
1.8.0. is the consumption meter and
2.8.0 is the feed-in meter.

If I understand correctly, your utility provider’s metering concept allows you to use both meters and run the photovoltaic system for both. Whether that makes sense is another question.

Currently, I have a green energy tariff at €0.2292 per kWh (kWh), a dedicated heat pump tariff would—if at all—be only slightly cheaper but with an additional monthly fee.

I only have the two-way meter, and my 9.9 kWp south-facing roof system generated 483 kWh in December, of which 358 kWh were fed into the grid.

Many grid operators have started allowing heat pumps only behind separate meters. So it’s possible that he had no choice because the grid operator optimizes the required peak load at the customers’ expense by turning off heating systems.

That is exactly the case.
