The differences that matter most
They differ most on price published. PlantPredict publishes Could not verify; PVsyst publishes CHF 700. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 19 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
PlantPredict is priced on an unrecorded basis 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.

19 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.
For utility-scale energy modellers and IEs who want a browser tool with unlimited projects, a documented algorithm set their lender's IE can audit, and automation. **Not for residential or C&I rooftop sales work, not for** teams that need layout-to-construction CAD (Design Pro is GIS-based, not an AutoCAD product), and not for anyone taking the site's structured data at face value — its schema publishes a price that its own pricing page contradicts.
Full PlantPredict 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 19 verified differences and 14 points where they are the same.
PlantPredict is priced on an unrecorded basis 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.
