Evaluation of Photovoltaic Offer and Components

Hello. We would also like to have a photovoltaic system and now have three offers. Or rather, we have only two so far and the third is yet to be prepared.

A provider from our town has offered us the following:

40x 410w Mono S4 Halfcut Modules = 16.4 kWp
Q.HOME+ ESS HYB- G3 3P 15.0 kWp inverter & 6.0 kW storage
including installation, scaffolding, new fuse box, ground electrode, equipotential bonding bar, and all formalities and registration for just under €29,400.

Distribution of the modules on the SSW and some on the NO.

The second offer is almost just as expensive but with significantly less kWp and from a company operating nationwide in Germany.

Do you think this is okay? I actually find it still quite expensive and am curious about the third offer.
Are the components okay?

Sounds quite expensive at first, but what exactly is being renewed in the fuse box? That would need to be itemized separately, because it is not part of a standard photovoltaic system.

Well, there is also a 6 kW storage included. Is that a real net price without VAT?

Well, there are also 6 kW storage units included. Is that a real net price without VAT?

Yes, including storage and without tax

Yes, it is net including storage

Sounds quite expensive at first, but what exactly will be redone at the fuse box?
That would have to be itemized, because that does not normally belong to a photovoltaic system.

A completely new fuse box will be installed, and the old one will still serve as a sub-distribution. The old one is from the 70s and cannot be expanded. Also, there is no grounding, which must be newly installed.

Take a look in ’s house construction thread on the last pages ... , there she also reports about a photovoltaic offer.

Maybe someone can also assess with what amount such a meter change with all the fuss normally comes to.

The photovoltaic components have been exempt from VAT since the beginning of the year anyway. It seems quite expensive, but comparability is difficult due to the new distribution and additional ancillary services.
