ᐅ "Electricity storage" in the cloud

Nevertheless, it can be assumed that electricity prices will continue to rise in the future and the feed-in tariff will decrease.

However, storage systems are expected to become much more affordable in the coming years.

Both statements are correct.
1. Overproduction will soon no longer be profitable, as there will be no reason for subsidies.
2. Battery prices are falling.
Consequences:
1. System design will increasingly focus on local demand—oversizing will become less attractive.
2. Storage will become an increasingly important factor for the economic viability of photovoltaic (PV) systems in both residential and commercial sectors, as it increases self-consumption rates.

Further developments:
The storage capacity of a battery system will no longer be the only considered component—charging and discharging power and intelligent system connectivity will gain greater importance for optimizing self-consumption. Contributions to self-consumption optimization include, among others, sector coupling, e-mobility, load management, and, in the commercial sector, peak shaving and peak shifting.

Current electricity cloud offerings do not primarily aim for profitability but rather for community and belonging. Knowing this, one can quickly estimate the figures and then make a better-informed decision—whether to agree or decline.

Great thing if the offer is affordable and fair. Some of these offers are surprisingly expensive.

delete the "some" and replace it with "each of the ones I have known so far" 😳

I’m reopening the thread because we are currently interested in a photovoltaic system. With cloud-based models, you pay a fixed monthly fee for "storage space" in the cloud for self-generated electricity. When you put the numbers into Excel, it still makes sense. I used the Senec values and a electricity tariff from a comparison website. Since no additional electricity provider is needed, the basic fee is eliminated. Depending on additional purchases, we’re talking about roughly 100 EUR per year for using 1500 kWh (1600 kWh), and about 250 EUR for 3000 kWh (3200 kWh).

If the batteries for cloud usage, e.g., Senec, are more expensive, it quickly becomes uneconomical.

What is your question? The topic itself has already been discussed many times.

If the batteries for cloud use are more expensive, it quickly stops being cost-effective.

The key question with a cloud solution is:
What annual consumption is included in the monthly flat rate, and is this enough to operate a heat pump in Hamburg?
How long will my storage last, and will it provide the required capacity? Ultimately, you are also making your own storage available free of charge for charging and discharging with external power.
I quickly stepped away from that solution and invested the capital in additional modules instead. So far, I have not regretted it.
