Not everyone is only concerned about the economic aspect of their own generation (through PV) or storage.
In short, your argument is a bit too short-sighted for me and is also factually incorrect.

Even though current storage systems are expensive, there is nothing meaningful to say about a possible payback period as no one can predict exactly what the future will do.

If I look back, however, I dare to make the assumption that through your own generation / storage of your own generated energy you will at least save energy tax / VAT per kWh (own consumption is not visible to the energy meter) and is therefore not possible. be taxed.
This is currently 13.2 cents per kWh that you save. If we put that on a storage of 20kWh with a lifespan of 15 years, you would save somewhere between 10k and 14k (at the same tax rate) alone. tax.
It is likely that this rate will increase over the next 15 years (lifetime of the storage set) and thus the savings will increase (and thus shorten the payback period).

We have not yet discussed the cost of the kWh of our own generated energy. My PV set has already been fully recouped and therefore every kWh of generation no longer costs me anything, aka free electricity. This also saves me the purchase price.
It is precisely at expensive times (in the early evening when there is no sun anymore but everyone is cooking/loading) that I often save myself by purchasing the highest rate. However, this is difficult to calculate and here too I cannot make a prediction in terms of prices, but I think that at 5 cents per kWh I am on the conservative side.
Based on the total lifespan of the 20kWh storage set, this results in another saving of +- 5k euros over 15 years.

Conservatively calculated, I arrive at a saving of 15 to 19 thousand euros in my situation.
So I am not counting any possible gains that could be made (I am very cautious about this because I do not think this will last) from trading on the imbalance market as Zonneplan does.

However, when I now see that a 20kWh storage set installed with a solar plan costs 8k at the moment, you still end up with a positive net bottom line and the set secretly already pays for itself after just over 6 years.
And again I think that is quite conservative at this time.

However, my expectation is that storage will become a lot cheaper in the coming period and certainly next year when the netting scheme will be overhauled (just an assumption on my part).

The moral of this story is that there is currently commercial battery storage for sale that, in combination with a PV installation, will pay for itself well within the warranty period / expected lifespan.

As soon as the netting scheme is overhauled (and given the noise now in the media, I expect this in the short term within 1 to 2 years) I will immediately push at least 20kWh of batteries into my shed.
