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.

It’s not cost-effective; you won’t recover the costs of a photovoltaic system with storage through feed-in tariffs or net metering. Calculating the value of a battery storage system based on feed-in tariffs is simply unrealistic. You need to consider price, lifespan, and cycle count. Currently, one kilowatt-hour from the battery costs you somewhere between 14 and 19 cents. The kilowatt-hour directly from the panels is, of course, cheaper. This raises the payback period of the system somewhat, but after that, the return on investment grows faster. Those who also have intelligent excess energy usage—not just batteries, but also heating water, running the washing machine and dryer, and using electric mobility—typically purchase less battery storage than usually recommended and achieve much better results both economically and in terms of energy self-sufficiency.

My husband wanted a storage system to be more self-sufficient. So the computers can keep running even during a power outage Hopefully, he has thoroughly researched the backup power capabilities of the system. There are many promises out there that often don't hold up.

You have to be very careful in choosing the right products for that. Standard battery storage systems cannot function as an uninterruptible power supply (UPS). If I remember correctly, they always require the grid frequency as a “clock signal.” Without this timing, there is no alternating current (AC).
What is the downside of a storage system? Everyone talks about it, many buy one, and many are “against” it. Technology only matures when some people actually try it out. It’s not a bad option; others spend x € per month on clothing, transportation, or leisure. Does it always pay off? In my case, I haven’t purchased any electricity since April...
