Way too expensive!
And don’t use a Senec storage system.
I’m telling you this as an owner of one.

Thank you very much for your input – also regarding the Senec storage system. This is already the second time I’ve received feedback like this....

The calculation is quite simple.

I consume 5000 kWh of electricity per year. Thanks to the electricity price cap, the cost per kWh is now 40 cents. So, I have to pay 2000 euros annually for the electricity used. That’s clear. Some people use a bit more, others a bit less.

A 10 kW photovoltaic system with storage costing 15,000 euros means that, with some planning, I can reduce my electricity purchase from the utility by about 70 percent. This results in an annual saving of 1400 euros, plus any feed-in tariff. That won’t be much, maybe around 200 euros per year.

So, the system will have paid for itself after 10 years. The difference is that these 1600 euros I pay do not go to the utility, but to myself. It doesn’t matter to me whether the 15,000 euros are sitting in my bank account or on the roof.

For me, the utility now only withdraws about 35 euros per month instead of 120 euros. And any future electricity price increases basically don’t affect me at all.

yes, according to some calculator. Unfortunately, the reality looks a bit different.

Even with your large system, you will have many days from mid-November to the end of February/early March where you will be glad to get a total of 4-5 kWh per day from the roof.

Unfortunately, I cannot confirm that. Yesterday, over the course of the day, 39.4 kWh was produced, and the day before yesterday it was 32.5 kWh.
Of course, there were a few bad days in December when output was in the single digits, but not too often.

Could you please share a screenshot of the app so it’s easier to understand? Or even better, the 2022 statistics showing how many complete cycles you had?

@Bausparfuchs as you can already see in this thread, €15,000 for a 10 kWp system plus storage is at best just a pipe dream. In today's reality, you pay two to two and a half times that amount for such a system.

Edit: the new processing time is simply far too short...

@Bausparfuchs I am also a fan of photovoltaic systems, but some of the calculations here are quite optimistic (except for the clearly too low feed-in tariff).
Achieving 70% self-sufficiency with such a small system is probably not possible in Germany.
And 15,000 is simply not feasible at the moment.
It's best to calculate without a battery first; then you might be able to reach a payback period of around 10 years.
With a battery, that is currently more difficult.
