Hello!
I'll start.

I ordered a 2.56 kWh (2.56 kWh) storage expansion today. €585 gross per kWh. Somehow, the money has to go somewhere. Based on the graphic, my ratio is 1.19 for the storage and 1.15 for the photovoltaic system (see X and Y coordinates), assuming a total household consumption of 7,500 kWh (7,500 kWh).
This might be of interest to some (@tomtom79). Unfortunately, I can’t share a direct link. Just search for the name of the figure if you want more details.

The average energy consumption for the last two days was 18 kWh each. I am quite satisfied with that, but unfortunately, the bathroom was too cool at 21°C (70°F). Since the radiator valve on the upper floor is also gurgling, I believe something is wrong there. I will bleed it several times. The heating technician is coming in the next few days—I’m curious to see what they find.
