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.

How long are the rates for the Senec Cloud fixed?
The feed-in tariff isn’t very high anymore, but it’s guaranteed for 20 years.I haven’t received any information about that so far.
Regarding self-consumption again: Does that mean VAT must always be paid on self-consumption (about 4.5 cents/kWh, assuming 24 cents/kWh)? In other words, without the Cloud, self-consumption in the example above would be 4030 kWh (181 € tax), and with the Cloud 6530 kWh (293 €)?

Hello everyone,
I am also facing the decision between cloud service or feed-in tariff.
Here are some basic details:
Photovoltaic system: 9.8 kWp
Storage: 10 kWh
Orientation: South, roof angle 7°
Estimated annual yield: 8,880 kWh
Please, no discussions about the storage system itself ;-)
If I calculate with these values and an assumed self-sufficiency rate of 62%, the Senec Cloud is significantly cheaper. Am I making a mistake in my thinking or calculations? (see attachment)
Regards and thanks
[ATTACH alt="stromcloud-vs-einspeiseverguetung-465251-1.png"]56363[/ATTACH]Hello,Calculations involving heat pumps are always a bit different from what solar installers’ tools can compute. I will get back to that later, as I have modified a calculation tool that includes hourly consumption, battery charge status, and photovoltaic yield to also reflect the high winter consumption of the heat pump.
Do you have a separate meter for the heat pump? That would significantly change the calculation (heat pump tariff around 20 cents/kWh, meter usually about 5 €/month, heat pump cloud package with SENEC for 5 €/month + 7.5 cents/kWh for kWh “stored” in the cloud).

No, a separate heat pump meter is currently not planned. I have adjusted my previous calculation to include VAT and income tax for self-consumption:
Is the advantage still with the cloud?!

The advantage would still be with the cloud?! Are there additional costs included for the cloud connection? For me, it was about 700 € (around 750 USD) for SENEC, and it would have been similar with E.ON. That comes to 35 € (about 37 USD) per year.
VAT and income tax are the same. Is that correct? I am not very clear yet regarding the cloud.
The heat pump tariff I have is 20 cents/kWh plus 60 € (around 65 USD) per year for the second meter. That would be around -300 € (about -325 USD) per year at 3500 kWh. The household electricity tariff would continue to have the option for free tariff switching in the future.
