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.

The photovoltaic price is net only, so we considered whether to go for an 8 kWp system to reduce costs.I wouldn’t reduce the size. That lowers the benefit more than it saves on costs.
I would rather ask a few other solar installers.
For 10 kWp, you should be able to get it for around 10,000€ (net).
Your price is 50% higher, which I think is quite a lot.

Definitely much cheaper than the current offer.

Yes, I have already done that and am waiting for quotes. The offer described would be from the electrician who is handling the house wiring through the construction company.

It definitely makes sense to consider sector coupling and think of electrical energy together with thermal energy.I have just looked at the device, but I wonder if it makes sense because the plan is to network the photovoltaic system and heat pump in such a way that hot water and domestic water are sufficiently available throughout the day. Adding an auxiliary heater in between?

hampshire21 Dec 2020 08:27That makes perfect sense. In summer, you feed the surplus from the photovoltaic system into the hot water tank. The heat pump doesn’t need to start. This saves costs and wear, since the heat pump is not required for hot water in summer and cycles less frequently.
