Hello everyone,
Since I have come across a few posts in other threads here in the forum regarding energy storage systems for photovoltaic installations and I am personally very interested in the topic, I found some more information during my research online.
Until now, I really believed that due to the currently low electricity prices compared to battery storage systems, these are not cost-effective.
The following study mainly refers to theoretical data and calculations. Nevertheless, it clearly shows how the situation can vary under different conditions.
On page 13, you will find a table with the various systems considered.
Under section 3.4.3
- it is mentioned, for example, that a photovoltaic system with storage has a feed-in power limit set at 60%.
Under section 4.2
- the system sizing is well compared.
Under section 4.5.1
- different financing examples are listed again, also taking into account KfW funding, along with various electricity price increases.
The best storage system was the Senec Home G2. Senec was able to offer such a competitive price due to the affordable replacement battery and inverter. Has anyone already installed one or informed themselves about it, or can share more general information on the topic?
Hopefully, this information is helpful to others as well.
Best regards,
Andi

Yes, as far as I know, the storage is not part of the company but belongs to the private individual. Therefore, you cannot save VAT on the storage. Everything stored in the storage is also considered a sale from the company to the private individual. Storage losses are therefore doubly frustrating.

However, it also says: "If the battery is part of a newly installed system, the input VAT deduction should be possible."
I will observe this in regard to the systems we will be selling in the future and report back here.
Best regards, Bauexperte
