Does Solset AI replace PVsyst?

Not for bank-grade yield studies. Solset AI gives a PVGIS-based estimate fit for quotations; PVsyst is the specialist simulation tool.

Yes, and many EPCs should: design and quote every lead in Solset AI, run PVsyst for projects that need a lender-grade report.

Comparison

Solset AI vs PVsyst

PVsyst is the desktop simulation tool engineers and lenders know. It is about the physics of a PV plant, in detail.

2: reasons to pick PVsyst instead

Solset AI is about the job: roof layout, structure, quotation, procurement, installation and invoicing. Many EPCs need a quick, sellable design for every lead and a PVsyst study only for the large ones.

Credit where due

Where PVsyst is genuinely strong.

Engineering-grade simulation: shading, mismatch, bifacial, trackers, sub-hourly, storage and ageing.
Wide weather-data support (Meteonorm, PVGIS, NSRDB, Solargis and others).
A low annual licence price and discounted education licences.

Pricing

How the two are priced

PVsyst: PVsyst sells annual licences in Swiss francs: PVsyst 8 Professional at CHF 700 a year, with education and research licences, and a one-month trial.

Solset AI: priced per workspace, not per user. A plan covers the company, extra seats are an add-on, and the Free plan needs no card and does not expire. Every current figure is on the plans page, read from the live catalogue.

PVsyst’s details are from its own website, read on 3 November 2026. Check their site before relying on them.
