The differences that matter most
They differ most on pricing model. PVsyst publishes CHF 700; Reslink Energy publishes USD 2000. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 25 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
PVsyst is priced per-seat and Reslink Energy is priced capacity-tiered. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

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 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.
Full PVsyst profileIndian rooftop and C&I EPCs whose sales reps carry a phone rather than a laptop and who want the design, BOM and proposal produced on the roof. It is not for anyone who needs a price they can rely on before they call sales: the same site publishes four mutually incompatible price schedules, in two currencies, on two billing periods, with two different sets of plan names — and a fifth figure appears on its Capterra listing.

They differ most on pricing model. In total we recorded 25 verified differences and 10 points where they are the same.
PVsyst is priced per-seat and Reslink Energy is priced capacity-tiered. 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.
