2 New Features in PVsyst Features in latest Version Meteorological input Extensions to System Definitions 3D Editing Batch Simulations and Optimizations Miscellaneous Tools Novelties cover May 2014 Sep Upcoming Version PVsyst 6.40 Text-based file format Improved 3D Editor and Shadings Calculation Battery-Based Systems Planned for Nov Page Page 2 2

3 Meteorological input Meteonorm Version 7.1 Built-in Meteonorm database changed from V6.1 to V 7.1 (updated database, improved interpolation) Comparison of yearly input files For different years, different sources or different sites Allows to estimate the variation that is used in P50/P90 analysis Creation of clear-sky model input Site and Linke coefficient Temperature Clear sky meteo data Simulation with clear sky model Monitoring data of known sunny days Quick crosschecks without measuring irradiance Page Page 3 3

4 Extensions to System Definitions Power Optimizers New: Associate an Optimizer to the PV modules Configure Optimizer Input and Output Visualize behavior of Optimizer Available in PVsyst: SolarEdge, AMPT and TIGO More flexibility with multi-mppt inverters New: adjust the power sharing of several MPPT inputs (before power was shared equally among all inputs) Page Page 4 4

5 Grouping of objects for common editing 3D Editing Editable ground objects Automatic module distribution on polygonal zones Enhanced import features from Helios3D New: Shading objects are imported too Improved performance for large and complex scenes Page Page 5 5

6 Batch Simulations Added more parameters to be used in batch runs The batch mode executes a set of simulations applying automatic input parameter changes: Choose parameters Edit parameter file Execute simulations Inspect results List of batch simulation parameters Project Parameters Meteo Input Project Site Simulation Variants Orientation Tilt Azimuth Shading Pitch of Rows/Trackers Ground Covering Ratio (GCR) Shading limit angle Tracker stroke angles Backtracking System Parameters Single Diode Model (R s, R sh, R sh (0)) Nr. modules in string Nr. of strings Inverter Model Nr. of MPPT inputs Inverter Pnom Grid Power limit Losses Thermal Model (U c, U w ) DC & AC wiring Soiling Light Induced Damage (LID) Mismatch Incidence Angle Modifier (IAM) Module quality Unavailability Page Page 6 6

7 Optimization Scans Tool for running optimization scans Automatic parameter generation Integrated visualization Simplified batch tool Simulation parameters: Tilt, Pitch, Azimuth Result Variables: Global incident and effective irradiance, DC power, power injected to grid More parameters and result variables will be added in the future Page Page 7 7

8 Miscellaneous Tools Carbon balance (CO 2 ) evaluation tool Based on CO2 Life Cycle Emissions (LCE) Definition of grid LCE Detailed LCE description of PV system Overview and time evolution of CO 2 balance Tool to study the Incident Angle Modifier (IAM) IAM curves for different models Fresnel Fresnel + AR Sandia ASHRAE Custom Effect on different irradiance components Diffuse Albedo Direct Global Impact on annual yield Page Page 8 8

9 Text-based file format PVsyst 6.40 All PVsyst objects will be written in human-readable text files Better interoperability between different PVsyst Versions Files can be inspected by users Opens future possibilities to interface with other applications Example for a shading scene Example for a PV module (PAN file) Page Page 9 9

10 3D Editor and Shadings Calculation PVsyst 6.40 Background images in 3D editor Example1: Screenshot from Google Maps Example2: Technical drawing Tools allow quick scaling, rotating and positioning of image 3D editor Based on OpenGL (V6.41) Makes use of hardware acceleration Faster rendering Faster shading calculations Page Page 10 10

11 Battery-Based Systems PVsyst 6.40 Complete overhaul of the simulation for battery-based systems Simulation and definitions unified with grid-connected approach Graphical tools for battery control optimization Adding Li-Ion systems ( V6.41) So far only lead batteries were supported Adding Batteries and Controllers for Li-Ion technology On the long term the simulation of hybrid systems will be possible (grid-connected with battery support) Page Page 11 11

12 Summary and Outlook Meteonorm V7.1 has become default built-in meteo source Input generation with Clear Sky Model for crosschecks without irradiance measurement Optimizers are supported (Solar Edge, TIGO and AMPT) More flexibility with multi-mppt inverters Helios 3D importation expanded to shading objects 3D editor with group editing and zone filling Tools to compare several yearly meteorological data sets Batch Simulations and Optimizations Tools to study IAM behavior and CO2 balance Meteo Input System definitions 3D Shadings Editor Analysis Tools PVsyst 6.40 PVsyst objects saved in text-based file format 3D Editor and Shadings Calculation based on OpenGL => Improved performance Battery-Based Systems synchronized with grid-connected approach Li-Ion Batteries and hybrid systems are on the way Page Page 12 12
