New Version 6.0 BETA (05.02.2013)

!!! A license synchronization is required before the update of PVsyst !!!

“Meteonorm Inside”

– Direct search of any location on the earth, using the well-known GoogleMap tool.
– Immediately get the monthly meteo values for any site, using the interpolating possibilities of Meteonorm 6.1.
– Synthetic generation of hourly values uses now the Meteonorm algorithm, improved by respect to the old PVsyst algorithm.
– Included import of meteo values from new databases, for example SolarAnywhere (SUNY model) satellite recent data covering the whole USA.
– Transposition model on tilted planes: Perez model now proposed as default instead of Hay, leqading to an increase of 0
– 2% yearly sum according to climate and orientation.

New Project management and simulation process

– New Project management Dashboard, with direct access to all parameters, simulation and results in a single dialog.
– Improved project management: copy, saving, transfers of calculation versions from projects to projects, copy of full projects.
– Losses: new organization of the loss diagram. New losses like LID, System unavailability, Inverter auxiliary or night consumption, Light-soaking gains for CIS.
– Batch mode for parametric studies: allowing to vary parameters in an EXCEL document, and get chosen simulation results of multiple runs as a table.

Improved shading calculations

– Direct shading factor calculation during the simulation (avoiding the interpolation uncertainties in the shading factor table).
– Optimization of the calculation of the shading factor, allowing calculations of big PV plants without limitation to some hundredth of trows or trackers (factor of 10 on the speed).
– Plants following the terrain, imported by Helios3D: analysis of the spread of orientations, management of the orientation average.

Detailed electrical shading losses

– Refinement of the “module layout” part, which allows to define the position of each PV module on the areas (“tables”) defined in the 3D shading tool.
– Modules arrangement in portrait or landscape, sub-modules in length or width within each module.
– Attribution of each module to a given string and inverter.
– Detailed calculation of the I/V characteristics under partial shadings in each Inverter input, either as pedagogic plot, and during the simulation for the determination of the “electrical losses” due to the shading mismatch.

PV modules

– Tools for specifiying low-light performances, and adjustment of the Rserie parameter accordingly. Low-light efficiencies may be included in the parameters in the database.
– Modification of the default values for Gamma, when Rseries is not explicitely defined by the manufacturer, giving significant higher yields of 2-3%.
– Import of a measured I/V curve for the establishment of the model’s parameters. – Sandia model implementation, and comparison with the one-diode model.
– New parameters: IAM profile in the module’s parameters, Vmax(UL) for use in US, full tolerance definition, LID for crystalline and Light-soaking for CIS.
– Easy choice of modules by manufacturers.

Inverters

– Multi-MPPT with unbalanced inputs
– define main and secondary inputs.
