Patch 7.2.8 - Date: 27/10/2021
Corrections:
- Detailed losses: entering unavailability hours does not crash anymore.
PVsystis the solar industry's preferred software simulation tool for bankability analyses and acceptance testing. This incumbent status is both a function of the platform's capabilities and stakeholder confidence in its results. Accurate energy modeling is essential to photovoltaic system financial models, capacity tests, and performance reports. However, accuracy is not innate to a specific software, but rather is a function of how that software is used. In this context, confidence is earned over time via repetition, experience, and accrued knowledge.
From the perspective of a power user, PVsyst is uniquely capable of providing a granular analysis of irradiance losses, array losses, and system losses. The granularity and control in PVsyst allows users to account for, among other things, module quality losses; string mismatch losses; soiling losses (including snow); ohmic wiring losses in the DC collection system; inverter losses; transformer losses; and auxiliary losses. The software is also unique in its ability to simulate system degradation and aging effects, which are essential for understanding energy production and economic performance over time.
PVsyst includes a large weather database and allows users to import meteorological data from other sources. The solar simulation platform also supports probabilistic assessments such as P50 and P90 analysis, which are statistical approaches used to increase confidence in the predicted solar resource and resulting energy yield.
In late May 2020, PVsyst released Version 7.0, which supports 64-bit processors. This release enables larger project capacities, more complex shading analyses, bifacial system modeling, and more advanced economic evaluations. While these increasingly powerful capabilities make PVsyst an ideal tool for engineers, the most powerful software tool is not necessarily the best tool for all users

The industry's relatively long history with PVsystis one of the primary reasons that the solar project investment community has largely standardized around PVsyst energy models. In 1992, André Mermoud, a PhD physicist from the University of Geneva, began developing Windows-based PV simulation software. Mermoud rewrote PVsyst in its entirety in 1999, enabling graphical interface capabilities. For more than 20 years, the developers behind PVsyst have supported U.S.-based project sites and provided periodic software and database updates.
