Framed as requirements, not a verdict. Both descriptions come from the same data.
Consider Enact if…
- AI-assisted workflows matter to you
- you work at utility scale
- your work is mostly residential
Installers who want one vendor for sales design, permit-grade engineering and post-install monitoring, and who will pay for those as three separate line items. It is not a single unified product: the "end-to-end platform" announced in January 2026 is, as sold on 2026-09-25, three priced modules — one of which still lives on a separate domain under a separate brand, with its own pricing pages that disagree with Enact's.

Full Enact 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.
