Electricity consumption at home, what is your consumption?

Optimally aligned. But usually the self-consumption is not that high if you don't have large consumers during the day, right?

Next summer we will see. By then we will have moved in. 9.9 kWp, south, 45 degrees. We are already considering how to make the best possible use of the yield. The heat pump will "cool" in summer, controlled residential ventilation will be running, we will try to schedule the dryer, washing machine, and dishwasher around midday, Windows Server 24/7, blah blah blah... We are hoping for a big saving.

You can manage it. You have to consume 30% yourself anyway. My heat pump is intelligently linked with the photovoltaic system, and my storage (7.7kW) manages the rest with forecasting and knowledge of what is going on in the house. Controlled residential ventilation hardly requires any electricity, not even the heat pump. In the visualization, the dishwasher or washing machine uses more electricity. When I calculate the savings on electricity purchases compared to previous years + the feed-in tariff from the grid operator - the investments (installment to KfW), I am in the "plus."

Yes, photovoltaic always makes sense as long as there is still a feed-in tariff. If that disappears, you need to think about how to increase the self-consumption quota or design the photovoltaic system along with storage based on self-consumption. Can you drain the storage overnight in summer? And what did you pay for the storage?

Is it actually allowed, if you are already a business operator because of your photovoltaic system, to sell the photovoltaic electricity directly to end consumers? Or do you practically have an exclusive contract with the grid operator? For example, putting up a sign: Charging electric car from 10 a.m. to 4 p.m. for 0.11 EUR/kWh, coffee 1.50, cake 2.50. Playing with the dog 5 EUR

Quite without polemics, yes, you can and are allowed to do that. But it’s not worthwhile. The subsidy is more lucrative.

And spend 12k€+ on that. As I said, nice to have...

I am more surprised that 200€/month or even more is considered normal. For that, the more expensive air heat pump or air-water heat pump or whatever, I find that expensive, especially surcharge technology calculated with consumption!

I’m also not getting upset about people who spend about 2500€ a year on smoking (around 1 pack a day).

But you have already used that argument several times. What do you have against smokers? That’s comparing apples and oranges or sugarcoating!
