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 was also offered the Senec Cloud about three years ago, but I simply couldn’t make the numbers work with Senec. The monthly service fee makes it completely unreasonable. And a "calculated self-sufficiency" is basically worthless.
Now, I’m happy to receive about 75€ (approximately $80) in feed-in tariffs every month.
My recommendation:
Solar PV system: definitely worth it
Battery storage: as Martial.white mentioned, only if it’s more or less free through subsidies. Otherwise, only if you really believe in the idea behind it.

Micha85891 Sep 2020 14:58Ok, thanks a lot for the tips so far.
To me, it just seems more logical to have a storage system rather than buying electricity from a provider. However, my house only exists on paper so far and won’t be ready to move into until August next year. I haven’t received any concrete offers from companies that provide photovoltaic solutions yet, so I only have estimated prices.
The only figures I have at the moment are:
Electricity consumption per year (family of three) about 3000 kWh
Electricity consumption for heat pump about 3500 kWh
A total of 6500 kWh results in electricity costs of around 1750 € per year with the cheapest electricity provider here (based on research on various comparison websites), which is quite a lot, or am I wrong?
Until now, I thought that with photovoltaic plus storage, I would save money over 20–30 years?
If you feed electricity into the grid via photovoltaic, do you get a cheaper tariff from the provider you buy electricity from? Or do I have to pay the full 1750 € over the year and then get credited about 10 cents for each kWh fed in? (Sorry for so many questions, but I just can’t find clear answers anywhere.)

Martial.white1 Sep 2020 15:06Since I don’t know the size of your system, the following statement might not be entirely accurate. However, I believe you won’t fully charge your storage during the time you use the heat pump for heating, as your heat pump and comfort power consumption will absorb the generated output.

Micha85891 Sep 2020 15:17Okay, but that actually makes sense again.
Your electricity supply can come from a provider of your choice. The electricity you feed into the grid will be compensated by the local utility company.
No cloud system, the roof should be as fully covered as possible, battery storage only if corresponding subsidies are available. Then it works, also financially.

That way, it works — also financially.Do I still have to report my annual consumption to the provider I choose and pay for it, or select a cheaper tariff?
