Current prices of photovoltaic systems / experiences with reliability?

Last offer before Easter was €1300 for 15 kWp with installation still in 2022.

That's already a good offer. We got two quotes: 9.6 kWp. The first one was around €1460 per kWp, the other €1320 (net). Both without scaffolding and with installation in the empty conduits prepared by the electrician. Other providers said they can only make an offer in October... One only has free consultation appointments in December(!!!). With the second provider, the modules are installed immediately after the roofing, but they are only connected in Dec/Jan. The full (fixed) price is due only after completion. I think I can't complain.

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 OFFERS with many current offer prices from other interested parties and their respective offer details.

Such a hint will get you banned ;)

I am putting an offer up. It is from last year, the modules are now installed. Final installation and connection will be completed by early August.

13.26 kWp. Bungalow in Brandenburg (near Potsdam). Two roof sides fully covered, all in black including the frames, power optimizers. The scaffolding was used by the general contractor.

I'll post an offer. It's from last year, the modules are installed by now. Final installation and connection will be done by early August.

Great offer. I think these days they are just wishful prices.

Have you already spoken with the tax office? Are you running this 13 kWp system as a hobby?
I also have an offer for 12.4 kWp (about €1250/kWp net), but I fear the tax office might not recognize this as a hobby.

This hobby issue doesn't make that much of a difference in the end. It's just one less sheet where you enter numbers that you already had to determine anyway.

(But yes - a 12-unit system at today's prices is not "likely to be profitable," so hobby status should usually not be a problem.)

I also have an offer for 12.4 kWp (approx. €1250/kWp net), but I am worried that the tax office will not recognize this as a hobby.

a) why the concern (I don’t share it) b) why is the hobby classification so important (I don’t find it decisive either)
