Construction costs are currently skyrocketing

Today the billing came in: It was a great photovoltaic year 2022 :)

6.24 kWp East/West
generated in 2022: 5847 kWh
used in 2022: 983 kWh

That results in €716 from the sale.
1300 kWh then still purchased from the electricity provider.

Good day, may I ask a question?

energetic quality of the building envelope ht

What values do your houses have there?

And how good or bad is:

I do have some thoughts after all... What life with an air-to-air heat pump is like.

I in Perth have the same amount of kWs on the roof, orientation south (for us north) and east and fed in last year

fed in 2022: 8628 kWh
consumed 2022: approx. 2000 kWh
bought 2022: 2954 kWh mainly for heating (ducted aircon). Water is heated with gas. There is no heat pump.

You get more for the sale, consume less than we do despite our sunny location. What do the 1300 kWh cost you?
