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 yield engineers and IEs at developers, lenders and EPCs who want a model backed by an assurance firm's operational dataset and are comfortable in a scripted desktop tool. Not for rooftop, residential or C&I sales work, not for macOS, and not for anyone who needs to see a price before talking to someone — the "View pricing" link leads to a JavaScript storefront that serves no product content to a non-JS reader.
