ᐅ Entry into force of the Solar Peak Regulation

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.

What will finally be signed can be read in the Federal Gazette. As far as I know, it has already passed two readings. Not much will change anymore, if at all, only minor details.

GewaltigNachhaltig will provide a video explaining the breakdown of the extra time after 20 years. I simply assume they don’t look at when it was negative or whether you fed in energy, but just add the time at the end. Whether they also include the amount of energy fed in, I cannot say.

Ah, there it is. So the calculation is based on full-load quarter hours. That means it is rounded generously, and each month has a different number of full-load quarter hours.
For example, if you accumulated 300 full-load quarter hours in the summer (time periods when the spot market price was negative),
the credit carries over, but each extended month "costs" a different amount of accumulated quarter hours.

and so on.

Complicated, but probably fair.

Is it possible to assess whether this is reasonably fair? At the moment, I can't really make sense of how long the extension might actually last.

I probably don't need to worry about this anyway, since the electrician will hopefully commission our system by February 19th.

Well, I assume that existing systems will be included at some point as well. However, that will likely take a few more years.

They probably add a factor based on the average hours of sunlight. Those who feel more qualified to verify this will likely do so.

Even if we manage to finish before the law comes into effect, it still affects us in a way, since we have to install the wallbox afterward.

Who will be able to understand all this when the houses are sold or when you yourself are 70 years old in 20 years?
