ᐅ Photovoltaic System: Costs and Savings Potential – Experiences?

The provider of the storage system as well as the energy cloud is Senec. The energy company EnBW is backing it.
What are your thoughts on Senec?

12 * €43.95 = €527.40 annual cost for 4,000 kWh

For 4,000 kWh, I only see €60.95/month + €100/year = €831.
Where are these cheaper rates?

Why is your consumption so high, anyway?

So these 4,000 kWh cost me a total of €887.40 per year, which corresponds to a price of 22.19 cents/kWh.

No, because you only get the contract if you also buy the overpriced photovoltaic system and the overpriced battery at the same time. Besides, with this figure, you have again forgotten the VAT and income tax.

In his case, I surprisingly didn’t find that to be true.
900€/kWp (around $960/kW) for 1 kWp (1 kW) is actually quite affordable currently.
And €6,000 (about $6,400) for the 10 kWh (10 kWh) battery can also be reasonable, although he mentioned a €2,000 (around $2,140) subsidy. In that case, the battery would of course be too expensive, since the subsidy could have been applied to a cheaper battery as well.

I have now also looked at the page. Gradually, the source of the confusion is becoming clearer to me... Could it be that the photovoltaic system and storage are already installed completely independently of the cloud provider? That would explain this calculation. Usually, with cloud providers, the hardware and contract are essentially rented together as a package. From the first reading, this rather seems to be a standard electricity supply contract with assignments of the Renewable Energy Act remuneration.

That makes the mystery around the VAT declarations and the income tax declaration from last year even greater?

This is the price list for new customers. We still have the old prices. Senec increased the prices significantly at the turn of the year. Whether this price increase will also affect us soon, I cannot yet say.

Our consumption is about 9,000 kWh per year because we have an air-water heat pump.

I just looked at the site as well. Slowly the reason for the confusion becomes clear... Could it be that the photovoltaic system and storage were already in place, completely independent from the cloud provider? That would explain the calculations. Usually, cloud providers offer the hardware and the contract as a kind of rental package. Here, it first appears to be a regular electricity supply contract with assignments of the Renewable Energy Act remuneration.

That leaves the mystery of the VAT declarations and income tax declaration from last year even more puzzling?

That is correct. The photovoltaic system and storage were procured independently from the cloud contract. The cloud contract was signed shortly after the system was commissioned.

Value-added tax had to be paid monthly last year and quarterly this year. But as I already mentioned, I did not include these in the calculations. That would, of course, change the profitability calculation of the storage. I need to recalculate that.

VAT does not affect the cloud contract, since it must be paid anyway, with or without the cloud contract.
