Assessment of photovoltaic offer including wallbox + storage

Good evening,

We have a first offer for a photovoltaic retrofit on our single-family house for which I would like to have your assessment: What I basically like: The contractor is a company from our city, so far the communication has been really very pleasant and friendly, both of which sound to me like a reliable implementation.

In addition, my question: I am somewhat losing track in the funding jungle: Which funding can I concretely plan for?

So:
Photovoltaic system with 11.2 kWP with a total of 28 modules
Growatt 7.6 kWh battery (item costing approximately €4000)
Growatt wall box
as well as everything else like inverter, installation, registration with the grid operator, modification of the meter cabinet etc. etc.

For a total of €29,000

I look forward to your feedback

In order to be able to assess the price at all, a few pieces of information about the installed components, i.e. offered inverter, modules, etc., and the layout on the roof are important. It makes a significant difference whether a hip roof is covered on three sides or a gable roof on one side.

Over 2000€/kWp = very very expensive.

For a total of €29,000

gross or net? 11.2 kWp x €1,400 = €15,680 Plus €4,000 for the storage. You should actually end up around €20,000 net... Possibly plus surcharge for hip roof, scaffolding, ...

Brutally expensive in my opinion...

Half a year ago I paid 1,250€ / kWp.

Even with inflation and price increases etc. (about 35%) you should come out under 1,700€ / kWp.

You are at 2,200€ / kWp (I assume this is the net amount?)

Thank you for your initial feedback, further information:

Normal gable roof built in 1990 with normal inclination, only one side is covered, normal access from the garden
