Strom-Cloud experiences vs. feed-in tariff?

how do you want to fully charge a 10 kwp storage with a 10 kwp system and then also have a heat pump attached?

And then you also have to pay tax separately on the kWh taken from the storage as direct consumption.

I have had a photovoltaic system on my roof for 1 year. 8.96 kwp.

I receive about 100 euros feed-in tariff and only have electricity costs of about 30-40 euros.

Nevertheless, I have to do a monthly VAT advance return. You pay VAT on the feed-in tariff and then also a non-cash supply tax on the direct consumption.

Then you also have to do a VAT declaration every year. You also have to do a profit and loss statement (EÜR). And the profit is then added to your income in the income tax declaration.

Better read up on the whole tax topic first. This is not so easy for laymen.

here are some data. You have to deal with that too then.

Your profit and loss statement (EÜR) for 2020 is wrong. You include the reimbursed VAT as revenue but do not deduct this (and possibly other VAT amounts) as expenses. Just as a note.

Please write this to me by email at muellrose2003@googlemail.com

I don't quite understand, since the Excel tool actually does all of this itself.

Thank you.

With approximately 81m2 of usable roof area, the photovoltaic system would have a nominal power of 10.56 kWp Storage: 10 kWh (4x 2.5 kWh lithium-ion storage with integrated inverter)

The storage must match the photovoltaic system. Our 9.9 kWp will cost about €15k. Gross, including preparation, registration, digital reading, etc.

Good day esteemed forum,
some time has passed again and our house project is progressing far too slowly for my liking. However, after 11 months the building application has finally been submitted "yeah"

Now back to the topic... we have finally received offers from local companies for our combination of air heat pump and photovoltaic system and I wanted to ask the experts here whether this is a viable combination...

Air heat pump:
Bosch/Junkers Condens Hybrid 7000i AW / GCH7000iF AW 7 O
Nominal power 2.71 kW
Supply / return temperature 35° / 28°
Annual performance factor 4.4 (with backup ... whatever "backup" means in this context)
Preliminary price: €15,498
(BAFA subsidy of 35% still applied for, since it was discontinued without replacement from 2021)

Photovoltaic system (without storage):
solar modules from Qcells
Hybrid inverter Plenticore plus 10 (including preparation for future storage)
9.90 kWp
Preliminary price (including installation, photovoltaic system registration, commissioning support): €15,653

Is this a viable combination? The topic of storage is off the table for us for now due to the high battery storage costs.

Somehow the wrong thread for this question.
There are hundreds of threads about heating here.
With a seasonal performance factor of 4.4, definitely not eligible for BAFA.
1500€/kwp for the photovoltaic system is expensive. Net or gross?

Yes, I know that this doesn’t quite fit, but from the beginning it was written in this thread that a photovoltaic system should be acquired to operate the heat pump, so I thought I would include the data of the heat pump as well.

The photovoltaic price is net only, that’s why we considered going for an 8 kWp system to reduce the costs.
