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.

I think the biggest drawback of storage systems right now is their lifespan. Our independent energy consultant and solar PV installer both advised against it for that reason. The system will eventually need to be replaced at a high cost, and then the calculations probably won’t make sense anymore. Unless you manage to store a very large portion of the solar panel electricity and actually use it yourself. However, that is likely to be difficult in our latitude.
We have prepared everything for a storage system. When the technology is more mature and affordable, we can upgrade at any time if needed.

Micha85893 Sep 2020 15:33I just received an email and a call from my builder. The photovoltaic installer has now prepared a quote for our house:
Photovoltaic system + battery storage + preparation for cloud service provider for a ridiculous €32,756 (about $35,000).
My builder then said that he couldn’t in good conscience offer this quote to any of his clients, and I will not have it installed either. It’s better, as previously mentioned here, to size the system to cover the heat pump’s needs and feed the rest into the grid!
The only advantage is that I now have some data like roof area, sun angle, etc.

That sounds incredibly (!!!) expensive.
For that price, I would expect at least a 20+ kWp system. And on top of that, there are monthly installments.

Storage: 10 kWh (4 x 2.5 kWh lithium-ion batteries with integrated inverters)
