Construction costs are currently skyrocketing

Received an offer: 5.28 kWp (16x IBC MonoSol 330 + SMA Sunny Tripower STP) & storage 5.12 kWh (BYD B-Box HVS 5.1) including installation / registration etc. for a total of 18,400 euros (gross)....

Very expensive. The upper limit for storage is 1,000 € gross / kW. Then you are at almost 2,500 € gross / kWp with the 5.28 kWp. Counter offer.

That's right, I read the one from 4.8. It was still at 1.63 then and today it jumped to 1.79. What happened?

Well, I said the labor market in the USA is booming… more than twice as many jobs created as expected.

It's expensive, but such small systems are less economical. Why so small?

What are you all buying memory for? It is still completely uneconomical.

Because it is not uneconomical in every case. In many cases, that may be true, but depending on how expensive the storage is, how electricity prices develop in the near future, and how long the storage lasts, it can certainly be economical. In the end, everyone has to calculate that for themselves. There are, of course, also some exceptions who acquire the storage for ideological reasons :p

A larger one has been requested. Waiting for further offers.

Regarding the storage: It may be worthwhile or not. It depends on your own consumption pattern. We are 2 people and I work from home.
What’s still on my mind: Since the storage is rather dead capital in winter, I would like to be able to charge it from the grid as well. I have a contract with Tibber and the prices there tend to vary throughout the day between 50 and 150%. The plan is to use a bit of programming (solar forecast, load curve, etc.) to fully utilize the storage.
