PVsyst

Bankability-grade PVsyst workflows from a team that has run thousands of P50/P90 simulations for lenders, IPPs and EPCs.

PVsyst Hub 28 articles · 97 glossary terms

PVsyst is the lingua franca of solar bankability. Lenders ask for it. Independent engineers review against it. Every major IPP technical spec references it. But the gap between a PVsyst report that survives ITA review and one that gets sent back for revision comes down to dozens of small decisions, weather file selection, horizon import accuracy, soiling and IAM assumptions, near-shade scene fidelity, mismatch and module quality loss inputs. This hub collects every PVsyst guide we have published: bankable reports, advanced shade analysis, energy yield deep-dives, integrations with Helioscope and Aurora, and India-specific weather and irradiation guidance. If you are building a project file from scratch, start with our bankable PVsyst reports guide and work outward.

Frequently asked questions

Quick answers to the questions we hear most about pvsyst.

What makes a PVsyst report bankable?
A bankable PVsyst report uses an audited weather file, a fully modelled near-shade scene, justified soiling and IAM losses, and explicit P50/P75/P90 outputs reconciled against an independent engineering review. Anything less gets flagged by the ITA.
Which weather file should I use for Indian projects?
Meteonorm 8 is the default but should be cross-checked against Solargis or NASA POWER for the specific coordinates. Variance above 4-6% in annual GHI warrants explanation in the report appendix.
How do I model bifacial gain in PVsyst?
Use the unlimited sheds 2D model for ground mount with site-measured albedo, then validate the bifacial gain factor against ASTM E1980 or recent field data. Default albedo of 0.2 is acceptable only as a placeholder.
