Cost of photovoltaics with storage

I just say power cloud.

Sorry, triggered :)

Although the headline didn't suggest it, I recently saw an interesting statement on this.
Check out the video on youtube "170 Wissenschaftler entlarven CO2-Rechenfehler im E-Auto-Kult" by nextmove.

I myself am also negative towards power clouds (they seem unprofitable and risky for the customer). However, I was not aware of the advantages of this concept for the overall power grid.

And yes, decentralization is generally the solution. Putting supply in the hands of a few large corporations is difficult, especially when they oppose meaningful change. Football fields full of battery storage or photovoltaic cells are also hard (profitable) to imagine in a "small" western country like ours.

These are 22 modules of 415kWp each.

The red roof is not mine

if that doesn’t come into affordable ranges, we will never install. Bungalow, outside 155m2, east-west occupiable gable roof 25 degrees without roof windows. Next time we’ll consider, if cars are capable of reverse charging and thus a large storage is available, maybe there’s the package from the dealership?

Oh, I see! Yes, then my worldview is back on track.

But this thread really destroys all my dreams...

What kind of opportunity costs does one have with a photovoltaic system?

The opportunity when purchasing a photovoltaic system with self-consumption is to continue buying all the electricity from a power supplier. The production of one kWh with a typical photovoltaic system costs 6-8 cents depending on orientation, location, and purchase price. Electricity from the supplier has long not cost that anymore.
Anyway: Photovoltaics are worthwhile, we probably agree on that.

It can always get worse… (30 characters)

Or there are such funny requirements in the development plan, like photovoltaic areas on the roof are only allowed to have a certain shape.
