PVsyst is designed to be used by architects, engineer and researchers, and it is also a very useful pedagogical tool. Is one of the most popular pv planning software in the market.
It includes a detailed contextual Help, which explains in detail procedures and models used, and offers an ergonomic approach with guide in development of a project. PVsyst is able to import meteo data from many different sources, as well as personal data.

Today's Example is a roof planning of 9.87 kWp using polycrystalline pv modules and 1 (one) triphased string inverter.
Step 1 Create sketch of the roof.
Step 2 Go to PVsyst - Import Meteo Data

Today's Example is a roof planning of 9.87 kWp using polycrystalline pv modules and 1 (one) triphased string inverter.
Step 1 Create sketch of the roof.
- Measure everything that can reduce system's performance
- Use the techical datasheets of the pv modules (Dimensions) and place the modules on your design.
- Choose the angle of the modules accoring your geographical place
- Make notes of the azimuth, around buildings (etc)
Step 2 Go to PVsyst - Import Meteo Data
- Import Meteo Data. Go to PVGIS Choose:
- Continent (Europe - Africa)
- Find Place (Coordinates GPS, Manually)
- Monthly Radiation
- Radiation Database: Climate SAF-PVGIS
- Calculate - From Browser ctrl+a and then ctrl+c
- Tools
- Meteo Database - import meteo data
- PV GIS (Europe - Africa) Monthly
- Location - Import
- Fix - Time Zone
- Save site
- Create Meteo
- Project design Grid Connected
- Project-Write plans info
- Site and Meteo - Country - Site Meteo file - Next
- Albedo - Monthly Values (Expert users)
- Common Values 0.2 (Urban) usual values from the table on the right
- Set high and low temprature - OK
Step 3 Near Shadings - Construct 3D Model
Step 4 PV System Planning
Good Luck! Please your comment is very important for us. If you know a better way for more reliable results please comment.
- Near Shading - Construction / Perspective
- Object - New - Elementary Shading Object
- Construct the 3D model based on the Sketch
- Object - PV plane in Sheds - Width - Length (Datasheet of the PV module) Place them - Pick them and Choose Partition in Module Chains and make your planning portrait or landscape
- Rotate whole scene (oriantation of the plan)
- Check your modules by performing Shadow animation over a day( Choose day of year - else relocate - When donne save and exit
- Update Oriantation Parameters
- Use in Simulation - According to Module Strings - Module String Shading Factor - Table - OK
Step 4 PV System Planning
- System - Presizing Enter Planne Power
- Select Modules and Inverter
- Number of Modules and Strings
- Detailed Losses
- Field Thermal Loss factor
- Constant Loss Factor Uc (Roof - free Field)
- (Reocommended Free filed 29 W/m2/K and roof 15 W/m2/K)
- Wind loss factor 1,2 free and roof 0
- NOCT Factor
- Free field 45 C
- Roof 68 C
- Ohmic losses has to do with cablings (recommended 1%)
- Missmatch losses 2% and 4% (Without Flash report)
- OK
- OK
- Simulation
- OK Results
- Save
- Report
- See your iso-Shaing diagramm
- Produced Energy
- Performance Ratio
