Hello everyone,

I would like to hear your opinion on a quote I received.

- Photovoltaic system with 10 kWp
- Storage battery with 6.5 kW
- Including installation

About 25,000 euros

That seems a bit high to me... so I’m asking here in the forum.
Thanks and best regards

The "gu-electrician" also handles the installation.

Oh, I see! How did you manage to use "someone else's" material in the construction?

I’m interested as well. The price is really good. Including installation, that would be around €22,000 (about $24,000). Installation (without scaffolding) doesn’t cost close to €10,000 (about $11,000), does it?

The question remains whether you received "everything complete" including the mounting system or just the modules with storage. Allegedly, solar installers are currently missing mounting systems (aluminum) or parts of them everywhere, causing all installation appointments to be postponed.... 🙁

I have included the K2 mounting system. Approximately €1500 (about $1600).
The installation costs him nearly €5000 (about $5300). Maybe he prefers external materials because the warranty then isn't his responsibility?

Wrong. He is still liable.



Are professional contractors responsible for defects in third-party materials?
It is not uncommon for professional contractors to be asked to install materials provided by others. But what are the legal consequences? Are contractors also liable for material defects?

...

Even if all technical regulations are followed, contractors can be held liable for defects if the final functionality is not achieved. This also applies when using materials supplied by the client. According to the case law of the Federal Court of Justice (Bundesgerichtshof, BGH), a project is considered defective if it does not fulfill the agreed function because the supplied material is unsuitable for producing a defect-free and functional result.
