ᐅ Experiences with Energy Cloud Services versus Feed-in Tariffs?

Hello dear forum members,
Our house construction plans were significantly disrupted by the coronavirus pandemic, but you have to accept the trade-offs when pursuing something important. The good thing is we had enough time to calculate all the options and actually decided to give up our original plan of a gas boiler plus solar thermal system, as a heat pump combined with solar panels turns out to be more cost-effective over 20 years.
The current plan is:
Solid construction house, 148m2 (Kalksandstein – a type of calcium silicate brick – up to the roof ridge plus facing brick)
Air-source heat pump (Junkers Compress 7400)
Photovoltaic system plus battery storage (no provider chosen yet)
Our builder recently received an offer from Senec that includes a cloud tariff. It sounds great on paper, but both I and our builder are somewhat skeptical and are currently researching and calculating further. Unfortunately, I’ve also found contradictory information online.
Is the cloud system worthwhile, or is the classic system with feed-in tariff better?
What do you think? What are your experiences with electricity cloud systems?
Thanks in advance for your answers.

With approximately 81 m² (870 sq ft) of usable roof space, the photovoltaic system would have a nominal capacity of 10.56 kWp.
Storage: 10 kWh (4 x 2.5 kWh lithium-ion batteries with integrated inverter) Incredibly expensive. Sounds like a defensive offer.

Micha85893 Sep 2020 17:27I’ve spent some time using online calculators, and based on the data for the photovoltaic system alone, I would have a net profit from the feed-in tariff of around 250€... Would that be realistic?
Photovoltaic system annual yield: approx. 9000 kWh
Self-consumption: approx. 6500 kWh (3000 kWh electricity consumption / 3500 kWh heat pump)
Feed-in tariff: 10 cents

Micha85893 Sep 2020 17:46I have now calculated based on the nominal output of the mentioned photovoltaic system, which can surely be obtained at a much lower price, right? Or is a 10 kWp photovoltaic system oversized for my annual consumption of about 6500 kWh???

Martial.white3 Sep 2020 20:32As @Tarnari says, the fuller the better. The corridor he suggests is also correct.
However, I believe no further persuasion is necessary, as @Micha8589 still assumes it is for personal use.
