ᐅ Photovoltaic system with battery storage, with or without cloud service plan

Hi everyone,
I searched a bit but didn’t find anything that fully satisfied me.
While I originally planned to install the photovoltaic system and battery storage for our new build in 4-5 years, I’ve now changed my mind. With current electricity costs at €110 and likely €130-140 for the new build, I can just take out a loan to cover €150-170 per month and install the photovoltaic system right away.
I asked the planning office to get us a quote. I also searched myself and received one today.
29x JA Solar JAM60S10-340/MR
or
30x Solarwatt Eco 120M Photovoltaic Modules 330 Heat Pump
and Senec . IES Home V3 duo Lithium 5kWh (5.5 kilowatt-hour) storage capacity.
So far, so good, but there is a line item for signing a cloud contract, and the cost-benefit analysis includes costs and savings related to the cloud. However, I don’t fully understand what the cloud service actually provides for my money or what it means.
I assume it’s not only SENEC offering a cloud service but others as well, and I’m not quite sure what exactly I get from it. Would I no longer feed electricity directly into the grid, and would I lose feed-in compensation for the surplus energy?
Do I need the cloud or not? If I do need it, which provider should I choose?

Everyone is free to calculate, weigh options, decide, and consider this topic as they wish.
We have an air-to-water heat pump combined with photovoltaic panels and a storage system. Our electricity consumption in April was 11 kWh.
When I see electricity prices others pay here, I understand why these discussions happen: we pay over 31 cents per kWh (including tax), while others apparently pay only 17 cents per kWh for their heat pump...

hampshire5 May 2020 09:02Whether a storage system is worthwhile can be easily calculated using your own assumptions. These assumptions include:
"assumed battery capacity" x "charge cycles per year" x "price difference between purchase and feed-in tariff" x "assumed useful lifetime in years"
and compare this with the costs.
Whether it pays off or not is up to you to decide. As with any purchase, you may also want to consider non-financial factors such as:
- Estimated difference between purchase price and feed-in tariff
- Estimated period of use
- Usable battery capacity (accounting for performance loss over the assumed period)
- Estimated number of charge cycles per year
- To get more precise, you can consider your consumption profile and the maximum power output of the battery – especially if you have unusually large individual loads.
- Costs
- Purchase
- Installation
- If applicable, additional cost for a hybrid inverter if the system is not AC-coupled
