ᐅ Waiving Feed-in Tariffs: Is It Always Feasible? Storage System Prices?

Hello everyone,
we are planning a small 5.7 kW peak system. We are still undecided about whether to include a battery storage or not. Through our installer, we have been offered a battery with 5.12 kW capacity for just under €10,000. That seems very expensive to me. Is it usually possible to get it cheaper if added later? Including installation?
My main question is this: assuming an annual electricity generation of 5,000 kWh, minus self-consumption (depending on whether there is a battery or not), there is not much left to sell back to the grid operator. Plus, the “effort” with the tax office... Despite simplifications for smaller systems, as far as I know you still have to handle the VAT return... We would gladly do without those few euros entirely if it means we are completely “off the hook” regarding the tax office. Is that possible?
Thank you very much for your help!

What exactly is your problem with the 2 minutes of work per year for the sales tax (you only need to enter 2 numbers)?To be fair, it’s actually about 10 minutes per quarter over a little more than five years. You first have to determine the numbers and then figure out where to enter them. It’s annoying, but doable. You can also share the task with your tax advisor, so you have even less to deal with.

DaGoodness18 Jul 2022 14:21Quarterly but only in the first year. After that, annually. (Possibly monthly in the first year as well, depending on the tax office.)
The form calculates it for me. It gives me the corresponding values directly.
And figuring out where to enter the numbers is a one-time thing. After that, you know it. :p

Thank you, but my question about *whether* I can do without it was not answered. Yes, I did answer. No feed-in means an off-grid system for self-supply.
@Deliverer ==> that’s exactly what the OP wants, a system for pure self-consumption with no feed-in. That is an off-grid system.

At the beginning of the year, you receive the statement from your electricity supplier or grid operator, showing the advance payments including VAT. You can basically report all the figures at the start of the year. Then include the self-consumption in the annual VAT return. This might not be 100% accurate, but it’s the usual procedure.
I now have two systems. For number 1, I reported monthly for three quarters, then annually. For number 2, quarterly for two years, then annually.

You have to collect the data first and then figure out where to enter it. It’s annoying but manageable. You only have to do it once while learning how it works. Excel helps. Then you just update the numbers in Elster each time. Really no effort.
Summary for the OP:
- yes, it’s definitely possible
- pointless without a battery storage
- alternatively, use a balcony system – better cost/performance ratio and no hassle with the tax office
- no feed-in (off-grid system) or small business regulation = no VAT, but almost 20% higher initial costs

An off-grid system has no connection to the public power grid.He doesn’t want that anyway. No feed-in to the grid is the goal. That makes an off-grid system the simplest option. He didn’t ask whether it makes sense 😉.Even though we’ve already given him the answer together...

It’s easier than building a real island to just tell the WR not to feed in any energy. However, that would be inconsiderate.
It’s better to simply feed in the energy and waive the compensation. Less effort than the other two options and you still do something good for humanity.
