Hello, what do you think about the consumption so far?

The heating has been running since around May 25, 2020.
The heat meter for the domestic hot water circuit was installed approximately 4 weeks later.

Is it really possible that our 9.92 kWh photovoltaic system has already generated 4,800 kWh? Unfortunately, I cannot check the data via an app yet, as we still do not have internet access.

Sorry, now with pictures. The first ones were removed because they were uploaded via link.

You haven’t provided any information about heating or hot water consumption.

Since when has the photovoltaic system been operating? If it has only been running for 14 days, the yield may not be accurate. If it has been running all year, the amount would be somewhat low, as most of the yield is typically generated during the summer.

Since when has the system been running? Since January 17th, we have just under 8,700 kWh, and the system has a capacity of 9.2 kWp.

Ah, here are the pictures.
On the electric meter, you only see the feed-in from the photovoltaic system, not its total production. Maybe you have already used 5,000 kWh of self-consumption? You can only determine that yourself (does the inverter display the production directly on the device?).
The heating was practically off, so the values are not meaningful. Wait for the next year when the heating has been on.

One would need to know what exactly was done, as the grid consumption is relatively high for such a short period. However, if underfloor heating for the screed was included, it’s not so problematic.
