In version 6.27 (19.09.2014)

Novelties:
  1. Carbon balance (CO2): evaluation tool and new page on the report.
  2. Management of Tigo optimizers, including definition, operating and shadings
  3. Inverters: temperature dependency of the nominal power (Pmax use, and high temperatures derate), specification of the Power Facor capability
Improvements:
  1. Auxiliary losses now explicitely specified.
  2. Component dialogs, 1st page: info availability an original database/custom.
  3. Big systems shading studies:* Improved calculation time of some verifications* Possibility of desabling the mutual interpenetration of fields (Helios3D)* Execution of some tests upon command instead of automatic* Helios3D: improved orientation analysis and tests.* Many objects: choice of selected object improved
  4. AC Losses after the inverter: take the Power Factor into account
  5. Improved the model of Shading Electrical loss: was enabled as soon as linear shading was present; now with a threshold (partial cell sheding).
  6. Batch simulations: still some updates.
Fixed errors:
  1. Synthetic generation: sometimes wind data (according to Meteonorm) were added.
  2. Master/Slave operation: error when the Vmppmin was reached.
  3. Littles errors (fonts) fixed in the report.

In version 6.26 (31.07.2014)

Novelties:
  1. Carbon balance (CO2): evaluation tool and new page on the report.
  2. Management of Tigo optimizers, including definition, operating and shadings
  3. Inverters: temperature dependency of the nominal power (Pmax use, and high temperatures derate), specification of the Power Facor capability
  1. PV module Rserie default value: according to 200 W/m2 relative efficiency (-3%).
  2. * Effect: only concerns modules for which the Rserie has not been specified. Low-light behaviour very close to modules with Manuf. specified Rserie
  3. PV module temperature behaviour
  4. * Up to now: the specified muPmpp value was the derivative at 25°C.
  5. * muPmpp calculated at 25 and 45°C: improves matching with the linear behaviour reported by measurements at oper. temperatures.
  6. * Effect: slightly decreases the temperature loss.
Improvements:
  1. Batch mode, significantly improved:
  2. * easier file management (re-use of old files), several new parameters;
  3. * Possibility of specifying a list of VCi (i.e. resimulate a whole project).
  4. Resistivity default values revised  (effect: slight decrease of Wiring loss).
Fixed errors:
  1. Helios3D management: error in verifications of orientations (spread) fixed. This sometimes prevented using old Helios3D scenes.
  2. Hay model: when the sun is behind the plane, the beam component doesn’t contribute to albedo (negligible effect with usual systems).
  3. Big shading systems: optimized a time-consuming verification.

In version 6.25 (16.06.2014)

Novelties:
  1. Main improvement about ModuleLayout management:
  2. All tables shown on a single plane – possibility of moving them
  3. Working table directly selectable on the 3D view
  4. Possible saving as an image  (BMP, JPG, or PNG: transparent)
  5. Print of the whole ModuleLayout definition
  6. Several Improvements/Optimizations inthe dialog and elaboration
  7. Export of results in the Report preview: Loss diagram also exportable
Improvements:
  1. Rewrote the batch mode, improvements
  2. Big shading scenes: general dialog speed optimizations
Fixed errors:
  1. Optimization of shading factor calculation was not activeted by default

In version 6.24 (21.05.2014)

Novelties:
  1. Report preview: new possibility of modifying units and language.
  2. Report preview: possibility of “Copying” the chosen results in the clipboard for analysis and versions comparisons in EXCEL.
Fixed errors:
  1. Error in Batch mode, when redefining the number of inverters.
  2. Printer choice: always takes the Default printer: fixed.
  3. Many bugs fixes after implementing the tool for reporting runtime errors.

In version 6.23 (01.05.2014)

Fixed errors:
  1. Mixed-orientation systems: sometimes error in the simulation => Inverter loss may be underevaluated by around -0.3%..

  2. Tracking 1-axis with not south-axis: some incoherences and modif. impossibilities in the definition dialog (not affecting simulation results).

  3. Prevent opening the software twice simultaneously, which may produce some conflicts.

  4. Grid Input/Output plots: showed variable E_Avail instead of E_Grid.

  5. Several minor dialog and display errors or improvements.

  6. Database update.

In version 6.22 (24.03.2014)

  1. Meteo conversion: import of year in the DD|MM|hh|mm format.
Fixed errors:
  1. SolarEdge: do not check number of strings or modules.
  2. 3D tool: fix window which could freeze.
  3. Added a new reporting tool in case PVsyst is crashing.

In version 6.21 (13.03.2014)

Fixed errors:

  2. Backtracking definition management: sometimes choice not accepted.

In version 6.20 (10.03.2014)

  2. Module Layout electrical calculations: simulation error in some special cases => alterate the Inverter losses.
  3. Improved speed when clicking on “Create variant from…” in the main project dialog.
  4. Improved logo quality on printed report.
