Hello,
I don’t believe such a system is absolutely necessary, or rather, I haven’t yet seen the significant benefits it offers. I prefer to simply open the window. What are the advantages of a ventilation and exhaust system, and what might be the drawbacks?

Wow, you again.
So, I would spend 70 minutes commuting to work using public transport, while by car it’s only about 20–25 minutes. The kids would also need quite a long time walking to daycare, and my wife ends up canceling client appointments because shopping unfortunately takes three hours.
By the way, I didn’t argue the car’s economic efficiency but its utility. And that’s exactly the parallel to the battery storage, which undoubtedly has value (examples above) but should not be argued as “cost-effective” or “paying off.” Because that is simply not true.

I don’t get it right now, but how on earth does someone come up with the idea to compare a car’s power output to the storage capacity of a battery?
The saying about comparing apples and oranges has never been more appropriate...
And if the so-called great sustainability of batteries is mentioned, one should also be fair enough to include their production and disposal.

Regarding solar storage, I would also say that it makes little sense from a financial perspective.
Personally, I would aim to maximize self-consumption as much as possible. For example, with a heat pump in winter, increase the supply temperature by 2°C (3.6°F) to use the building structure as a storage medium. Or schedule water heating primarily during midday hours. Regardless of whether the sun is shining, that is usually when the highest daily temperature occurs.

Overloading the battery storage is actually a good thing. However, during winter, the electricity generated by the rooftop system is mostly used directly within the household (lighting, heating).
Still, from the perspective of a private household, the power grid functions as a form of storage. You can feed electricity into it freely and draw it later, but there are losses involved since you sell electricity, for example, at 12 cents and buy it back later at 25 cents. This loss, however, is significantly smaller (!) than the loss associated with a private battery storage system. I recently calculated an example related to this...

It’s progress or staying at the current state of technology. That is my conviction. I would suggest being more open-minded. What counts as progress and what doesn’t may only become clear in a few decades, if at all.
There was a time when only electric vehicles existed (and carriages :=) ), and then the gasoline and diesel engines were considered progress... and where are we now?
Besides, you will also act economically in many areas, not just in a future-oriented and ecological way, unless you are one of the lucky ones with practically unlimited money (this applies to everything from buying food and clothing to building materials to the vehicles you use...).
