Ah ok.
Although, who can install it cheaply? The current normal craftsman price. That is just high at the moment.
The fact that photovoltaic systems need to be considered separately in terms of fire safety has been confirmed by the fire department dozens of times. Just look up fire department statements about it on YouTube. They are also plausible.
So there is a loss of performance. Ok. You just have to plan for it in the long term.
Of course, if you are an electrician or electrically inclined, you can repair everything yourself. But the average housewife or lawyer probably won’t mess around with it themselves. So you should keep maintenance costs in mind. That’s okay. After all, you also plan a small monthly reserve for the washing machine.
In other words, it pays off in about 12-15 years? Then consider the loss of performance... replacement, etc., etc...
Hm
For me, it’s currently uninteresting.
But I am open to further opinions. Maybe one or the other argument will still convince me.
