ᐅ Electricity Consumption of a Heat Pump

I don’t think a consumption of 50 kWh is that high. That is the total daily electricity consumption for a house.

You can’t be serious... 50 kWh per day means about 18,000 kWh per year; even with an electric car, I would call that more than high.

Photovoltaic yields are very low from November to February. Today I had about 3.5 kWh of output, which was already quite a lot.

Where is that considered a lot?
Here, we had 21.8 kWh today.
And days like this happen from time to time, even in winter. So far, December has delivered 170 kWh here. November still had 379 kWh.
There is sunlight in winter as well.

If you’re asking where the location is, maybe you should first share where you are currently achieving your yields and with what capacity. Otherwise, these figures are completely useless and just thrown out there.

The weather conditions in a country like Germany are not uniform. Here in the Ore Mountains, today was the first day with good yields, two more days with moderate yields, and the rest were very low. Compared to last year, I am at about 80% of the yield from last December.

Of course, the location is the beautiful Rhineland in North Rhine-Westphalia, and the system has a capacity of 10 kWp.

That’s nice for you. However, you should also specify the size of your system. And this definitely needs to be considered on an individual basis. My system is designed for my needs; you probably have different ones.

In snow and frost, your system—likely built with significantly higher investment costs—produces just as much as mine. Which is nothing!

So please tell us, how large is your system? Mine has 7.5 kWp and is completely sufficient for my circumstances.

A consumption of 50 kWh per day from November to February is quite normal. In the other months, thanks to photovoltaic panels, consumption should then approach zero. That’s how it is for me as well. Heating, hot water, and normal usage like cooking, refrigerator, ventilation, etc., all add up. I only need about 6 to 8 kWh per day in winter, but still require 1,000 liters (about 264 gallons) of heating oil for heat generation.
That roughly totals to 18,000 kWh annually when calculated.

The fundamental problem is that surplus electricity generated in the summer cannot be accessed in winter. And suitable long-term storage solutions are not currently in sight.

I really can't believe that. You can't get that yield with a 10 kWp system. How much do you expect to have in summer then? This is not a fairy tale session here.
