A seller calculates the payback of their own battery. We calculate whether any battery pays off — and how big it should be. From your actual consumption, your tariff and current electricity prices.
You have PV and are considering a battery. Or you have a battery and want to know whether it works as it should. Or you are building a new installation and do not know what capacity to buy. In all three cases the question is the same: how much the battery really saves — and how long it takes to pay for itself.

Indicative assessment with a revenue stack in a low / base / high range and Critical findings.
The calculation runs on the server over the actual 15-minute day-ahead series and ERÚ tariffs.
The form is short. Leave blank what you do not know — the platform will ask for the missing input and will not fill it in with an estimate.
No, but without it a battery makes sense only exceptionally — typically with a large gap between the high and low tariff. The platform will assess it and tell you when it does not work out.
Yes. That is the whole point of an independent assessment — a result of “not worth it” is as valid an output as “worth it”.
Fill in what you know. The platform asks for the missing input and does not fill it in with an estimate — we would rather ask than return a number that does not hold up.
