ᐅ Photovoltaics at Any Cost – Current Situation and Available Options

Hello everyone,
After countless rejections due to overload, availability, and delivery issues, I have finally received an offer for a photovoltaic system.
The system is planned for our new build (completion in 2023). We have a gable roof, almost south-facing, with a 30-degree pitch, fully usable, about 50 sqm (540 sq ft) of roof area per side.
The house is being built in Bavaria, about 60 km (37 miles) from Thuringia.
The offer surprised me a bit. The following items are included:
14x MAXEON modules at 430 W each, heat pump system, totaling 6.02 kWp - €11,138
1x Tesla Powerwall 2.0, 13.5 kWh - €10,400
Installation, etc. - €3,130
Total: €24,668 net
I find that quite expensive. I would leave out the battery anyway, but even then, I think the price for the 6 kWp system is too high. Apparently, this is currently the price you pay in Bavaria if you can find someone at all. For me, the question is whether it even makes sense to invest right now or just pay for electricity. Of course, it’s a matter of calculation, but if you follow the discussions here, those prices seem sky-high — or not?
Is it better to get offers from other regions? Are there any recommendations around the 97XXX area?

Seriously: if we only thought economically, no one here would own a house and everyone would rent for their entire life...Again, the question is, what does this have to do with the topic? Does a storage system bring you as much joy as your house?
As I said, the environmental benefit of a storage system is still highly questionable!

Could you explain that in more detail? What do you mean by 5-6 kWh from a 4 kWh battery? Is that per day, per week, or per month? What do you mean by a period when "nothing" is generated? How large is your photovoltaic system?5-6 kWh is needed during the period when no electricity is generated (so from evening until the sun shines on the panels again in the morning). The system is 6.5 kWp, oriented at 45° exactly facing south (great for winter, about 9000 kWh generated annually!).
The battery is therefore empty in the morning before electricity is generated again.
My brother has an 8.5 kWp system with an 8 kWh battery on the neighboring, slightly larger semi-detached house, so we can compare well.
For us, the question of "is it worth it" never came up. It’s a KfW40+ standard plus a passive house. With so many subsidies (which are no longer available), even the battery was worthwhile (which was also a requirement for KfW40+).

Starting January 1st, the price will initially be 40 cents for 80% of the annual consumption. And no one can reliably predict how this will look in two years.
It's not like the prices for photovoltaic systems and batteries haven't increased significantly either. He could have gotten this system for two-thirds of the price, if not half, two years ago... and at 1.5% interest, not 4%... A photovoltaic system can also be added later. It's certainly not wise to do so at any cost, but that’s exactly the topic of this thread.
In the medium term, the question of whether to install photovoltaics may no longer be one. You will find mandatory requirements for new builds and roof renovations in all federal states, and in some (probably Baden-Württemberg first) also for existing houses without renovations. Of course, you can consider whether to wait until it becomes compulsory (and then much more expensive) or to invest now and benefit from it.

I am currently at 0.8 kW, which over 8 hours (22-6) amounts to 6.4 kWh. In summer, however, you also have air conditioning, pool, etc., so I could probably drain a 10 kWh battery storage during the night.
