Hello everyone,
Since I have no prior experience, I would like to get some general information.
Our new building will be heated using an air-to-water heat pump.
What would generally and overall be the advantages, potential savings, and costs of installing a photovoltaic system on the roof? Is it worthwhile or not?

You need to be careful that the temporary construction power meter has a backflow preventer because feeding the photovoltaic surplus back into the temporary construction power meter is not allowed! That would cause problems.
We had a final bill of €58, including screed heating, with photovoltaic (including battery storage) on the temporary construction power.

And if the house connection hasn’t been completed yet, can the system also be used for the heat pump to heat the screed (using temporary construction power)?
