The market standard computes fast — in hourly steps, with representative days, in a single assumed world. That is enough for a feeling, not for a bank. EXAIOS deliberately takes the harder route: the full reality, the bad scenario, a proof instead of a claim. Others finish sooner — EXAIOS finishes correctly, and fast enough.
Every recommendation carries an optimality certificate, demonstrably close to the mathematical optimum and reproducible under a SHA256 seal — your bank receives a proof, not a marketing figure. The installation is not chosen by the expected value but by the p10 cover: the one that survives the bad year wins. And we compute at full 15-minute resolution, because the demand charge is billed on 15-minute peaks — anyone computing in hourly steps cannot price peak shaving correctly, structurally.
Find the site, size it, convince the bank, build, procure, operate — everything meshes, nothing gets lost between five separate tools. Two-stage and practical: an immediate screen for the first view, the certified result asynchronously afterwards — defensible on the same day. Procurement is neutral: machines choose machines, bias-free from the worldwide catalogue, with no sales interest.
EXAIOS is the neutral layer above all systems: it connects those who decide, advise, build and operate — without disturbing existing systems. One reproducible truth for everyone: adviser, bank and installer see the same sealed figure. And the layer improves with every project — each site sharpens the next decision.
Certificate plus p10 plus 15 minutes plus reproducibility make no sense together if all you want is speed — and mean everything once capital is committed. That is exactly the ground EXAIOS occupies alone: the burden-of-proof side. Others finish sooner; for whoever commits the capital, correct is the only thing that counts.
EXAIOS returns the decisive figures for every site:
We publish no invented numbers. Compute your real site in minutes — the first indication is free.
Start a free indicationFor a pretty instant estimate, yes. For a figure that holds up in front of a bank, no — there provability counts, not speed. And with the two-stage model (instant screen plus certified result) EXAIOS is fast enough as well.
Because the demand charge is billed on 15-minute peaks and a large part of a battery's value sits exactly there. An hourly tool cannot price peak shaving correctly, structurally.
Every result carries a demonstrated distance to the mathematical optimum and is SHA256-reproducible — a proof of optimality a bank can check, instead of a claim.
