Tax benefits from photovoltaic system?

Hello,

We are considering how to plan the planned photovoltaic system in the most tax-efficient way possible.
For this reason, we decided against 40+ (there was something about that) and want to finance the system differently.

In my mind, I have that I need to set up a GBR to sell the electricity and pay VAT etc., but in doing so, I can also deduct all costs, including the loan and so on.
Is that right or wrong?

Also, an acquaintance told us that you could rent out the roof to your own GBR to optimize everything even further.
Does anyone know about this, or is the acquaintance just talking nonsense here?

Have I read correctly that from 10 kWp onwards, the Renewable Energy Act surcharge must be paid?

Thanks

that I found a GBR to sell the electricity

A single person cannot found a GBR, you need two for that. In that respect... :rolleyes:

A GBR does not have to be established. The operation can also be run as a business without a business license. Registration with the tax office is sufficient. There is a document with further information from the Bavarian tax office.

Besides, an acquaintance told us
that you could also rent out the roof to your own GBR to optimize everything even further.

Who then taxes the rental income? Oh right, that’s you ;-)

We are considering,

Then “you” are automatically a GbR.

Rather on the wrong track. Deciding against 40+ kfw only to finance it differently is a scenario with a very big minus.

Have I read correctly that from 10kWp the Renewable Energy Act surcharge has to be paid?

As far as I know, this regulation was abolished at the end of 2020. Check again ...!
