Which might suit you
Framed as requirements, not a verdict. Both descriptions come from the same data.
Consider 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.
Full PVsyst profileConsider RatedPower (pvDesign) if…
- AI-assisted workflows matter to you
- you work at utility scale
For developers, IPPs, EPCs and engineering firms who need to iterate hundreds of utility-scale layouts and carry them through to interconnection and off-taker-ready detailed engineering. Not for anyone who needs a published price (all three tiers are "Talk to sales"), not for rooftop or residential, and not for buyers who need site prospecting outside the specific geographies where Enverus PRISM International data is licensed.
