Those who are currently planning a photovoltaic system or installing one in February should take a look at the Solar Peak Law.
In times of negative electricity prices, it seems that there will no longer be any compensation, or operators will be forced to limit the system’s output. From my perspective, this means that photovoltaic systems without storage will likely no longer be economical compared to those with storage.
Our (storage-free) system will be installed on the roof this week, and I hope we can commission it before the deadline for the law to take effect.

Just a general question about throttling: there are already systems with 70% throttling for some reason.
Does the percentage refer only to the kWp of the entire system, meaning the maximum capacity? Or is it always 70% (60%) of the current output that is fed into the grid?

If you have 10 kWp, you can feed in a maximum of 7 kWp. So, if you’re charging your electric car at 3 kW during this time, you are feeding in the full amount...

If you have 10 kWp on the roof, but the inverter can handle more, the module capacity is decisive.

Do you mean the 70% limit that applied until 2023 (I have that too)? It refers to the feed-in. So, I have a 10 kWp system on the roof, limited to 70%, meaning it can feed in a maximum of 7 kW (which is always 70% of 10 kWp). Thanks to an 8 kW inverter (where the throttling is configured in the software), I can charge my car with 7.2 kW in summer, and the remaining surplus of about 1 kW goes into the grid.

Since we are supposed to receive compensation for 20 years, a somewhat complex calculation method adds the period of negative prices/no compensation at the end. So, for example, you end up with 20 years and 6 months of compensation. I’m not exactly sure how this is implemented, but it doesn’t sound like a good deal. All compensation agreements expire after 20 years on December 31. However, the adjustment is made during peak solar output in summer. For 24 peak sun hours, I effectively receive the feed-in tariff for January 1 (which regularly is 0 USD). For the next 24 curtailed sun hours, I get January 2’s rate (again 0 USD), and so on.
I would rather say that it then shifts from a time-based compensation guarantee to one based on volume (amount of electricity) (at least that seems logical to me). However, this would only be possible with a smart meter, which would then have a higher fee. This needs to be carefully considered.
We will see the exact details in the actual law, or have you already read it?
