ᐅ Evaluation of Photovoltaic Proposal and Components

Hello. We would also like to install a photovoltaic system and currently have three quotes. So far, we have received two, and the third one is still being prepared.

A local provider offered us the following:

40 x 410 W mono S4 half-cut modules = 16.4 kWp
Q.HOME+ ESS HYB- G3 3-phase 15.0 kWp inverter & 6.0 kW battery storage
Including installation, scaffolding, new distribution board, grounding rod, equipotential bonding bar, and all formalities and registration for just under €29,400.

The modules are arranged facing south-southwest and some towards northeast.

The second offer is almost the same price but has significantly lower kWp and comes from a company operating nationwide in Germany.

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

Sounds quite expensive at first, but what exactly will be replaced or upgraded in the electrical panel? You would need a detailed list, as this is not typically included with a standard photovoltaic system.

Well, it also includes 6 kW of storage. Is that a real net price without VAT?

Yes, including storage and without tax.

Yes, it is net including storage.

That would need to be specified separately, as it is not part of a standard photovoltaic system.

A completely new breaker panel will be installed, and the old one will still be used as a sub-distribution board. The old panel dates back to the 1970s and cannot be expanded. In addition, there is no grounding, so that also needs to be redone.

Take a look at @kati1337’s house construction thread on the last pages ... https://www.hausbau-forum.de/threads/hanghaus-in-der-suedwestpfalz-unser-hausbau-2-0.44121, where she also reports on a photovoltaic offer.

Maybe someone can also estimate the typical cost of a meter change with all the associated procedures.

Photovoltaic components have been exempt from VAT since the beginning of the year.

It seems to be quite expensive, but comparing prices is difficult due to the new distribution and additional ancillary services.
