2014 PV Performance Modeling Workshop: Pvsyst Updates since 2013: Bruno Wittmer, Pvsyst
Pvsyst has introduced several updates since 2013 including: 1) The ability to model up to eight module orientations and mix two specific orientations coupled to the same inverter. 2) Linking the 3D scene editor to the module layout so modules can be manually or automatically placed in the 3D scene and referenced in the layout. 3) Determining production variability and uncertainty to report P50 and P90 yield evaluations based on meteorological and other simulation uncertainties. 4) Miscellaneous improvements such as simulation speed, additional module parameters, report formatting, and new tutorials.

- 2. Page 2Page 2 •Multiple Orientations • 3D Module Layout • P50 / P90 report • Miscellaneous improvements
- 3. Page 3Page 3 MultipleOrientations • Up to eight different orientations • Two specific orientations can be mixed (coupled to the same inverter) "System summary" window available from different dialogs General overview of the parameters: Orientations, sub-arrays, shading 3D fields defined. Identifies the uncompatibilities between these 3 entities (orientation and areas matching)
- 4. Page 4Page 4 3DModule Layout • Link between 3D scene editor and module layout In the 3D scene construction the modules can be placed manually or automatically In the module layout dialog the 3D scene can be consulted to get an overview
- 5. Page 5Page 5 Productionprevisibility – P50 / P90 • Variability ( RMS or s ) determination − Based on the observed Meteo data variability − Increased by other uncertainties of the simulation process (PV module parameters, inverter, soiling, degradation): • Each uncertainty is quantified by a RMS probability, which are added quadratically. • P90 yield evaluation = P50 - 1.28 * s
- 6. Page 6Page 6 MiscellaneousImprovements • Simulation Improvements – Improved speed – Light soaking, LID, IAM in module definitions – Grid power parameters – More detailed ASCII output • Meteo Data – Improved DST management (also USA) – SOLARGIS Tool – Better dialogs and error messages • Report – Formatting improved – P50 / P90 report • System – Automatic bug reporting tool – Proxy support for internet access – Import/Export projects – Unicode support for file paths • New Tutorials – First Project, Meteo Data management, 3D shadings – To be extended… • Etc..
