Study Notes
PVsyst Overview
- PVsyst is a software used for the study, sizing, simulation, and data analysis of complete PV systems.
- It is also a useful educational tool.
PVsyst Simulation
- PVsyst offers two levels of solar simulation: Preliminary Design and Project Design.
- Preliminary Design is a rapid estimation tool suitable for pre-sales designs.
- Project Design is a more detailed simulation that requires hundreds of parameters and decisions.
PVsyst Tutorial
Step 1: Open PVsyst
- The main page includes four main parts: Project Design & Simulation, Recent Projects, Documentation, and Pvsyst User Workspace.
- Project Design & Simulation is the main part of the software, used for the complete study of a project.
Step 2: Open Project Management & Simulation
- This step involves working on a project, either standalone or grid-connected.
- Project Management & Simulation has two parts: Project and Variant.
Project Details
- Project contains the geographical site of the system, meteorological data, and general parameters like Albedo definition and sizing conditions.
- Project filenames have the extension *.PRJ.
Variant Details
- Each system variant contains detailed definitions of the system, resulting in a simulation calculation.
- Variant definitions include solar panels, inverters, geometrical layout, shadings, electrical connections, and economic scenarios.
- Variant files have the Project's filename with extensions such as VC0, VC1, VCA, etc., up to 936 Variants per project.
Step 3: Enter Project Details, Site & Weather data
- Enter a project name, select a site file, and navigate to the desired location on the interactive map.
- Press "Accept Selected Point" to populate the meteo file.
Step 4: Select Type & Orientation of PV Panel System
- This step involves selecting the type and orientation of the PV panel system using the options in the Variant part of the program.
Orientation Details
- The solar panels are installed on a fixed tilted plane with a tilt and azimuth angle.
- The azimuth angle is defined by the angle between the South direction and the direction where the panels are facing.
PVsyst is a tool used for studying, sizing, and simulating complete PV systems. It offers two levels of solar simulation, Preliminary Design and Project Design, for rapid estimation and profitable solar system planning.
