Is a photovoltaic system also sensible in the West or East?

: Congratulations on the investment!

The feed-in tariff (which is already at rock bottom anyway) would expire before we went online.

The amount of the feed-in tariff depends on the registration date and not on the commissioning date. You can gain a few months there.

Yes, a storage solution is currently still too expensive and more of a hobby, even though the idea is still very appealing to me. I also had it calculated. Ultimately, I could save 1,222 kWh per year. That would then be a price per kWh of 35 cents (gross) - without taking into account the losses of the storage.

I personally still hope for the further development of bidirectional charging (V2G / Vehicle to Grid). There, the electric car is activated as an energy storage for household needs. A charming idea, in my opinion.

: Thanks to you! Are you sure about the statement regarding the registration date? According to the Renewable Energy Sources Act Clearing House, the IBN counts (Frequently Asked Legal Question No. 110) -> am not allowed to post a link.

Ultimately, I was able to consume 1,222 kWh p.a. more because of this

That's how I understood it and that's what I was told as well. I will see what they make of it, because my papers have been lying with the grid operator for ages and haven't been returned yet. There were 8 months between registration and commissioning for my system. That makes quite a difference.

According to the solar installer, it applies if the modules are on the roof and would theoretically work.

Thanks to [Virus], my modules are now only arriving in mid-April.

That is what I was told as well; the decisive factor is supposed to be when the modules were installed on the roof.
