ᐅ Savings from photovoltaic system, battery storage, and electricity cloud

In the construction cost thread, the topic of the usefulness of battery storage, energy cloud services, etc., came up recently.
So, here is a dedicated discussion thread on this subject.
Since May 2020, I have had a 10 kWp (kilowatt peak) system on my roof and a 10 kWh (kilowatt-hour) battery storage in the utility room. Additionally, since August 2020, I have been using an energy cloud service provided by the company Senec (EnBW).
With this service, the electricity fed into the grid during summer is credited to an account and can be drawn again in winter at favorable conditions. The general opinion on this topic everywhere is that it is not worthwhile. The same applies to the question of whether to have storage or not.
Therefore, I made a cost breakdown for myself and compared my current expenses with different scenarios such as "energy cloud service or regular electricity tariff," "photovoltaic system with and without storage," and the costs "completely without a photovoltaic system."
Attached you will find my breakdown.
Looking forward to an active discussion.

According to your calculations, it really seems to be well worth it. We are currently building as well and unfortunately didn’t have any budget left for a photovoltaic system, but based on your numbers, it would have actually made sense to finance the system over 10–15 years. The monthly cost would probably still be lower than buying all electricity from the grid. With the electricity prices that the future will bring, most likely even more so. I definitely need to run the numbers once our house is finished.
And regarding all the saving and parenting comments, I can only say one thing: it’s basically nobody else’s business, and since you get almost all your energy from renewable sources, I don’t see the problem. You put together a good system that lets you pay less—even at maximum comfort—than I currently do for my 95m² (1023 sq ft) rental apartment. You did everything right.

The prices mentioned here seem completely unrealistic and are about as helpful as answering the question: what did your house cost?Earlier you expressed doubt about whether it was really possible to get a system at that price in 2020. My post was simply meant to show that it was possible to be in that range—nothing more, nothing less.Snowy36 schrieb:
The prices mentioned here seem completely unrealistic and about as useful as the answer to the question: how much did your house cost? Did you have to pay separately for scaffolding? Gross price? Fully finished? Otherwise, nothing is comparable. From what I see, most people here quote net prices. Since everything is entirely "all in" for us, I assume that with others it also includes scaffolding/installation/permits/planning permission/etc. And black is currently "in," so fully finished is automatically offered as standard.Snowy36 schrieb:
The prices mentioned here seem somewhat astronomical...Astronomical in the sense of "overpriced"?D
