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?

Why do you need to decide now? Just include conduit pipes and that’s it. Integrating something "conceptually" at this stage only leads to costs without added value.We are planning very budget-conscious. That’s why we’d like to know whether to already include a buffer for photovoltaics in the budget or not... So this is a preliminary, basic consideration about whether to include photovoltaics or not.

Those are impressive figures. 2x 100% Do you have the figures for winter as well?
Currently, it makes the most sense to prepare the house for photovoltaic installation and consider in the future, depending on factors like feed-in options, whether to actually install a photovoltaic system on the roof.
With an air-to-water heat pump, I can’t store all the electricity I draw, since battery storage systems are still very expensive, right?

With an air-to-water heat pump, I can’t really store all the electricity I generate because battery storage systems are still quite expensive, aren’t they?

That’s what we were able to do.
