Photovoltaics at any cost - current situation and offers

Otherwise, I had already started a thread on the topic.
https://www.hausbau-forum.de/threads/einsparung-pv-anlage-speicher-stromcloud-diskussionsthread.43899/

So first of all, congratulations on the price and thanks for the link.
Of course, you also need to know about the 2,000 EUR subsidy ;)

I would recommend everyone to read through the thread, as it puts a lot into perspective for probably 95% of all interested parties, but everyone should form their own opinion and ask or inform themselves.

- Is the load profile comparable
- According to your figures, you come to over 260 cycles per year. That is extremely high for a system size = storage size.
- The latter is probably due to your load profile and presumably the reluctance to change anything. Realistically, in my impression, not achievable for most people with heat pumps. Especially not if you even try to shift consumption to the day (water heating / daily heating).
- Your data on charging and discharging the storage seem to have "optimized measurement points." :P Under 2% loss during storage, your system seems to be the solution to the energy transition :D Realistic?

Of course, everything is speculation. No one knows how long the storages will last. Maybe longer than we think.

Photovoltaic system 28.35 Kwp, storage 10.2 kWh, installed 2020, Renewable Energy Sources Act remuneration 9.27 cents/kWh

Storage costs: €7,340 net less €3,040 subsidy

2021 charged: 2,694 kWh
2021 discharged: 2,290 kWh

2022 charged: 2,497 kWh
2022 discharged: 2,094 kWh

In the first 5 years, VAT would still have to be added to the own consumption, in return the tax refund for depreciation over 20 years would be deducted, both are not huge key figures. The same applies to financing at 0.5%.

These numbers show how pointless a memory is.

Well, explain that then. My storage will be paid off in 8-10 years with a 10-year warranty.

These numbers show how nonsensical a storage is.

This has already been proven many times that a storage can be profitable, depending on purchase, subsidies, and usage etc. One should not just generalize here. Nevertheless, currently a positive calculation is difficult. But that is more due to political reasons. If only we had invested as much money in photovoltaics, H2O and battery technology as in nuclear power or combustion engines, the world would look completely different again :rolleyes:

The political support for the car lobby also annoys me the most. It felt like just last year it was "OMG, we'll never get good batteries, diesel above all," and now "Our 8 Series BMW manages XY km and has ZZZ HP, we're the coolest."
