HelioScope or PVsyst?
They differ most on price published. HelioScope publishes USD 159; PVsyst publishes CHF 700. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 27 differences drawn from the same sourced dataset that powers both product pages.
Verified against the vendor’s own pages.
Pricing
These cannot be compared on a single number
HelioScope is priced capacity-tiered 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.

Which might suit you
Framed as requirements, not a verdict. Both descriptions come from the same data.
Consider HelioScope if…
- your systems fit within 1.25 MW DC (Basic) / 5 MW (Pro) / 30 MW (Enterprise)
- AI-assisted workflows matter to you
For C&I designers and engineers who need a layout, a bankable-grade production estimate and a sales proposal without leaving one tool. Not for residential one-roof sales work (the same vendor routes that to Aurora) and not for jobs above 30 MW DC — the vendor publishes a hard design-size cap on every tier.
Full HelioScope profileConsider PVsyst if…
- you need a price you can plan against before talking to sales
- you need it to connect to tools you already run (15 named)
- you are comfortable with desktop software and its constraints
- you work at utility scale
- your work is mostly residential
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.
