PVsyst is a preliminary design tool for evaluating the effectiveness and deployment possibilities of photovoltaic systems for converting sunlight into usable electricity. Designed from the ground up to be a valuable tool for engineers, researchers, educators, and architects, PVsyst can quickly and reliably model the possible deployment formats for PV systems, create full reports, visual graphs, and detailed data tables that are ready for exporting and use in other software.

PVsyst is an all-in-one software package for the evaluation of PV systems. It provides built-in tools for evaluating the initial system designs (with a large database of pre-built components for easier setting of starting parameters and a full editor for tweaking each component to fit your needs), a system sizing tool for exploring optimal inverter sizing, and other parameters of your PV setup, interactive and highly customizable 3D Shading Scene tool that can simulate the effects of your setup, comprehensive simulation and reporting service, support for calculation of grid storage, direct integration with metronome service for placing and testing of your PC setup on any simulated location on Earth, a database of meteo data, other PV modules and components, multi-year batch simulation of aging effects, and many more tools and services.

This highly-customized simulation tool is perfect for the simulation of PV systems of all sizes, from small personal projects to large PV platforms intended to provide reliable power delivery to a large number of customers. It even features a 3D CAO tool for drawing the geometry of the entire PV system, automatic sun position and shading calculation for beam components, and much more.

PVsyst is available for purchase under several types of licenses (Pro30 and Premium, all with one year of official support with the option to extend it), the entire app can also be tested for FREE in a 30-day trial.

Installation and Use

The installation package of PVsyst weighs in at just under 200 MB, enabling any user to quickly download it and deploy it on their home, work PC, workstation, or virtual machine. The app officially doesn’t support access via Remote Desktop Client or running at Windows and Application servers. Instead, it is intended to be run natively on Windows 7/10, or under virtual machines on Windows 8/8.1.  Mac and Linux users can run this app using virtual machines.

Minimal system requirements are set at any PC that can run Windows 7 or 10, with at least 1 GB of system RAM memory, 1GB of free storage space, a graphics card that supports OpenGL 2.0 or higher, and a minimum screen resolution of 800 x 600 pixels (SVGA).

Features and Highlights
  • Comprehensive design tool for evaluating photovoltaic systems of all sizes.
  • Compile a detailed evaluation of the effectiveness of your PV platform. Detailed computation of PV conversion effectiveness.

  • Build-in support for location searching via Google Maps and Meteonorm interpolation.
  • Direct shading simulation calculation takes into consideration the effects of nearby big plants.
  • Tools for parameter optimization.
  • Optimized for Windows 7 and 10. It can be used in Windows 8/8.1 via virtual machines.
  • Available for FREE via 30-day trial demo.

What's new in this version:

New features:
- Shadings: completely reviewed the 3D fields definition dialogs. The fields should now be defined (preferably) according to the number of modules, in landscape or portrait. The field sizes and the number of modules are now defined simultaneously
- Shadings: definition of the partition in rectangles and strings (for electrical shadings) now within the 3D field dialog. This dialog includes now tools for analyzing or extending the definitions to other fields of the scene
- Shadings: new pedagogic tool for calculating and viewing angles between planes. This tool is also useful to understand the modifications of the orientation of the plane according to the base slope
- Reports: you can now compare two reports side by side with a highlight on the differences
- Backtracking: new dialog for the management of the pitch between independent tables, and choosing the reference pair of trackers. This dialog allows now the analysis of the pitches in the whole scene, and identifies the possible incompatibilities
- Meteo data: implemented new Meteonorm 8 meteorological database
- Meteo data: integration of SOLCAST as meteorological data source
- Language: complete software translation into Japanese and Chinese.

- Bifacial: modified and updated 2D model acceptability conditions
- Module layout: check of the suitability of the PV module (number of diodes, submodule layout should be "In Length" or "TwinHalfCut")
- PV module: in submodules layout definition, added a category "Exotic" for diverse not standard modules
- Simulation performance: with trackers, the integrals for diffuse values are now saved with the variant file
- Help: update pages about partition in strings of modules, AC losses, inverter limits and current limitation
- Components database update.

- Module Layout: fixed numerical finding of maxima in PV-curves. This may slightly change the results of Module Layout calculations
- Grid limitation losses: fixed a bug in the accounting of the grid limitation losses. Does not change the final results of the simulation
- Shadings: fixed bugs in Polygonal fields definitions
- Simulation for tracking big systems: optimized the calculation of the integrals for diffuse
- Meteo import: solved an issue with the filenames.
- Losses: fixed the accounting for array losses whenever the array power is almost null.
