Strom-Cloud experiences vs. feed-in tariff?

The power consumption is then 4-5 times higher (yes, photovoltaic power, but that also has to be taxed plus lost compensation). I would also like to question whether 2 hot water cycles a day are more harmful than 6 months of standstill with all the stagnant fluids.

preliminary price (incl. installation, registration of photovoltaic system, commissioning support): €15,653

A smaller battery should be included for that. Look around again.
In Bavaria, which is considered more expensive than MV, offers from a high-quality installation company were available with 10kWp, 8kW storage, fully installed under €20,000 incl. VAT.

For that, the electricity consumption is then 4-5 times as high (yes, photovoltaic electricity, but that also has to be taxed plus lost remuneration). Whether 2 hot water cycles a day are more harmful than 6 months of downtime with all the standing fluids is something I would also question.

Again, such a matter of belief. With the small system, the Renewable Energy Act surcharge is excluded (from 1.1. it is up to 30kWp instead of previously only 9.99). One can just calculate again roughly: Let’s calculate for 1 kW from the photovoltaic system 8 ct and a feed-in tariff of 9 ct. Then the heating element would have to pay off from the difference of 17 ct to the electricity tariff. If you want to assume the longer service life of the heat pump, you have to add another 5-10% of the heat pump costs. To add some estimated data, let’s assume that the photovoltaic system heats the hot water tank from surplus with 2 kWh/day on 150 days. Then we have 300 kWh per year times 15 years = 4500 kWh - times 10 ct difference = €450, plus the heat pump portion €500 and an acquisition price for the heating element of €700 - initially doesn’t look so good against €950 - but free is the good feeling of a higher and more environmentally friendly self-consumption rate. As always: by changing the assumptions, it gets better or worse.
For me, it’s not worth a thought game - the heating element goes into the hot water tank. Even if it should not pay off (which I do not believe), it has a positive effect. I have invested money more poorly before.

The good feeling of a higher and more environmentally friendly self-consumption rate is free of charge. As always: by adjusting the assumptions it gets better or worse. For me, it’s not worth a thought experiment – the heating rod goes into the DHW tank. Even if it shouldn’t pay off (which I don’t believe), it causes positive effects. I have invested money worse.

What is supposed to be environmentally friendly about senselessly consuming electricity with a heating rod instead of making it available to the neighborhood (or other useful purposes)? o_O

Whether the heat pump really lasts longer because of this and whether the heating rod was produced CO2 neutrally is also debatable...

Hello everyone,

I am also facing the decision whether to choose Cloud or feed-in tariff.
Here are a few key data points:
Photovoltaic system: 9.8 kWp
Storage: 10 kWh
Orientation: South, roof 7°
Estimated yield per year: 8,880 kWh

Please no discussion about storage etc. ;-)

So if I calculate with the values and an assumed self-sufficiency rate of 62%, then the Senec Cloud is significantly cheaper. Do I have a thinking/calculation error somewhere (see attachment).

Regards and thanks

At first, it reads well.
Questions that come to mind spontaneously are:
- Is the storage sufficient for your self-consumption?
- How does the calculation look if storage/self-consumption behaves differently?
- What is the cost of Senec’s storage compared to a freely purchased model?
- Do you not need an electricity meter for the Cloud solution (150€ per year)?
- Self-consumed electricity isn’t free (taxes!!!). They should be higher for the Cloud since self-consumption is higher (I at least assume that the Cloud usage is calculated analogously to a free-of-charge value benefit like actual self-consumption – taxation must happen somehow). Please include this in your calculation.

I suspect that in the end your savings shrink considerably. Just 150€ for the meter alone. If the storage is 1,200€ more expensive than a comparable freely purchased model, only 41€ per year remain over 10 years. Then there’s the tax issue.

I accepted a top offer last week. 40 modules with SolarEdge and power optimizer. 14 kWp. Price per kWp: 955 euros. Including installation etc
