The differences that matter most
They differ most on price published. Archelios Pro publishes Not publicly disclosed; PVsyst publishes CHF 700. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 23 differences drawn from the same sourced dataset that powers both product pages.
Verified against the vendor’s own pages.
These cannot be compared on a single number
Archelios Pro is priced quote-only and PVsyst is priced per-seat. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

23 differences, ordered by how much they are likely to matter — pricing transparency first, then capabilities the vendor explicitly confirms or denies.

Scroll the table sideways to see both products. The capability column stays in place.
Framed as requirements, not a verdict. Both descriptions come from the same data.
European design offices and installers who want a properly priced, properly documented simulation tool with real CAD and BIM interoperability, and whose projects sort cleanly into power bands. It is not for teams that need a CRM, a lead pipeline or a polished sales proposal — the output is a technical PDF and an economic analysis, not a homeowner-facing document — and the tier boundaries are hard: at 101 kWp you are on a €1,490 licence, not a €990 one.

Full Archelios Pro profileFor engineers and IEs who need a yield number a bank will accept and are willing to work in a single-machine desktop tool. Not for anyone who needs macOS, a browser, a shared cloud workspace, a terminal-server deployment, or a sales proposal — the vendor explicitly excludes servers, Citrix, Remote Desktop, Azure Virtual Desktop, Windows Enterprise editions and cloud-synced folders, and sells no CRM or proposal module at all.

They differ most on price published. In total we recorded 23 verified differences and 12 points where they are the same.
Archelios Pro is priced quote-only and PVsyst is priced per-seat. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.
We do not name a winner. Both are described from the same verified data, and which suits you depends on your requirements — the differences above are the facts; the choice is yours.
