PVSYST SA

PVsyst SA is a Swiss company based in Satigny, near Geneva, that develops PVsyst, a Windows-based software package for designing and simulating photovoltaic systems. Originally created in 1992 by physicist André Mermoud, the software models hourly energy yield, shading losses, and financial returns for grid-connected, stand-alone, pumping, and DC-grid solar installations. It is widely used by engineers, architects, and researchers to produce bankability reports accepted by lenders and is considered a standard tool for solar project financing analysis and acceptance testing.
