Comparison of photovoltaic system offers

Prices are net completely fine. You can do without 70% soft on East/West. What about the garage that is marked there? Otherwise, fully occupy where it makes sense and of course also feed in.

Also check if the [LWWP] can be controlled sensibly, as this is not necessarily the case.

Also check whether the air-water heat pump can be controlled meaningfully, as this is not necessarily the case.

Nice to have, but it wouldn’t be a disaster if it’s only optimized via timer control. For me, the module for smart control would cost €200-€300, which is rather not worthwhile for me.

More important is that the heat pump can actually use the photovoltaic electricity and is not connected separately to another meter.

Let me guess Viessmann? I also gave it up, now I do it via time control or via APP.

No, Panasonic. I still have the first photovoltaic winter ahead of me, only then will I see what I might be giving away. For the module costs, I can almost heat for a year.
