Current prices of photovoltaic systems / experiences with reliability?

Hello everyone,
this thread is about current offers/prices for photovoltaic systems on single-family homes.
Transparent prices indicating system size and price per kWp would be interesting.

To compare these, a rough indication of the region and possibly specific conditions (multi-family house at 10m height, difficult access, etc.) would also help.
Currently, prices are rising sharply.
If this thread interests you, I would be glad.

At the moment it is extremely difficult to quote prices, mainly because there are no parts. Previously, 10 KW were between 15k and 20k depending on the roof and region.

For orientation, a visit to the p h o t o v o l t a i k f o r u m is worthwhile. There is a subforum ANGEBOTE with many current offer prices from other interested parties and their respective offer details.

I see it the same way as

Comparing users doesn’t help.
I completed the game 2 months ago.

Got the first offer. Gathered opinions within my circle of acquaintances. Clear consensus: "way too expensive! They want to rip you off. Go to XYZ!"
Then, over a period of 5 weeks, I obtained further offers.

The offers came in weekly and each offer was higher than the previous one.
So back to number 1. Even among acquaintances, it was then just "well... apparently that’s how it is now."

Last week a neighbor from the street said I could get a better price from a local solar installer. He had just had a fresh offer made.
I called for fun. Installation if commissioned immediately: in 18 months!!!
Of course with a price escalation clause.

So it simply doesn’t help to compare offers with other people.
Renegotiation is not an option at the moment anyway. There are dozens of other customers waiting behind you in line.

Thank you for the feedback.
It helps me understand the market situation.
The demand seems to be huge at the moment.

In the past, 10 kW were usually between 15k and 20k depending on the roof and region

So "in the past" that was too expensive. From 10 kWp you could calculate with about 1000,-€/kWp all inclusive before 2021. I still paid 1058,-€ in expensive BaWü in 2021. Shortly after that, the Panama thing happened and since then everything has gone crazy...

The last offer before Easter was 1300,-€ for 15 kWp including installation still in 2022.
