The PVsyst development team is pleased to announce the availability of PVsyst 7.4.7 is an energy modelling tool that helps in analyzing how much solar energy can be harvested into an electrical energy from a particular site or location.

PVsyst 7.4.7 - Date: 23/05/2024

Improvements:
- Databases update.
Corrections:
- Circuit, single line diagram: PVsyst does not crash anymore when displaying the inverter name in some configurations
- Grid storage, peak shaving: the "EUnused" loss is now accounted for correctly
- License: reading identifiers on some specific computer configurations no longer causes crashes (specific V7.4.6)
- Losses: the MV line ohmic loss is now correct when several transformers are defined (specific V7.4.6)
- Module layout: tables are no longer moving when performing string attributions
- Module layout: PVsyst no longer freezes when opening the module layout for large systems
- Module layout: all orientations are now available for electrical attribution when using Huawei inverters
- Module layout: tables are not hidden by others anymore
- Optimizers, Huawei: simulation now runs faster with large systems
- Optimizers, Sungrow: the aging tool now works correctly
- Shadings: sliding a row within the zone tool is now working properly
- Shadings: a spurious input field when creating a 4-sided roof object has been removed
- Shadings: when importing a PVC file with trackers, the axis now always follows the orientation choice of the user
- Simulation, stand alone: the calculation of the missing energy value "E_Missing" is now correct when there is no backup generator
- Simulation, stand alone: the loss below the minimum voltage of the controller is now correctly accounted for
- Tutorial: a new PDF tutorial was added: "3D Procedures: Ground and Topography".

PVsyst is the solar industry’s preferred software simulation tool for bankability analyses and acceptance testing. 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.

The industry’s relatively long history with PVsyst is 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.
