Electricity consumption at home, what is your consumption?

I'm interested in your opinion now. We have had two meters installed. Consumer and pump. Actually, the plan was to support the pump with the photovoltaic system as well. The solar technician said we should watch the pump tariff for the first year and then decide. We somehow don't like that very much. What is your general view on this?

With photovoltaics, only one meter, otherwise you can only reduce either the household electricity consumption or the heat pump electricity consumption with the self-produced electricity, but not both at the same time. At least, that is how I understood it.

Yes, that is also true. The question is, what use is a discounted pump rate? Clearly, it is a calculation exercise. But we cannot know what the consumption will look like.

Well, if most people don’t even install a second meter for the heat pump tariff because it’s not cost-effective... In old buildings with high heat demand, it will pay off. In new buildings, rather less or not at all. But it depends on the heat demand and whether you provide the heat pump with an efficient heat distribution system. Maybe you can find comparable properties in the heat pump consumption database based on which you can estimate your expected consumption.

I just find it super complicated. On the one hand, I think the goal has to be to maximize self-consumption. We only get a feed-in tariff of 9 point something cents. And then when the pump is needed, the photovoltaics tend to deliver the least yield for self-consumption. Will a discounted tariff for the pump help us more over the year when it’s needed, or is the sum of yield in winter plus feed-in tariff higher with two meters? Damn it, if they had installed only one meter as originally intended, we wouldn’t even be thinking about this. Now that it’s different, we’re totally uncertain.

Consumption 2020

5600 kWh of which 1600 kWh are attributed to the heat pump.
2460 kWh of the consumption could be covered by the photovoltaic system (44%)
9000 kWh were fed in.

It was a year with a lot of home office, hence also the high degree of self-sufficiency (without storage).
