Is it possible to have self-generated electricity from a photovoltaic system and heating electricity?

Hello everyone.

I have a question:
Our new building is to be heated with an air-to-water heat pump and additionally a 9 kWp photovoltaic system will be installed.

The electricity from the photovoltaic system should of course primarily be used for heating. If there are surpluses, household self-consumption should take place first before the electricity is fed into the grid.... Basically no problem.

In the heating months, my photovoltaic system will contribute little, so I am considering taking a heating electricity tariff as it is significantly cheaper.
Then I will have two meters....
Is it possible for the photovoltaic electricity to still be used for both consumers (heating and household)?

Thanks for your answers.
Best regards Christian

Hello,

before you invest money in a photovoltaic system, I would rather spend more money and do a deep drilling and a brine heat pump.

As you yourself say, if the photovoltaic system produces, you don't need it, and if you need it, it doesn't produce!!

: I did it like this: Photovoltaic 6.3 kWp on southwest + northwest roof, plus a LG ESS and no separate heat pump meter. The heat pump will be a split unit with 6 kW heating capacity. The ESS and the heat pump will be put into operation in spring; I will then report here later about the operating behavior...

Oops.. I just noticed that I made a mistake: 9 kWp is of course quite a significant figure.

The subsidized heating electricity probably makes no sense at all. Therefore, only one meter for everything. Issue closed.

Double-check: Just take out the calculator.
