Release Notes

It is now possible to select PV configuration with 1-axis horizontal NS tracker in Prospect app. Note that this feature is available only with Prospect Pro plan.

- Default rotation limit of tracker is set as ± . In next release it is planned to allow user to edit the rotation limits

- Currently it is possible only to select option with backtracking strategy enabled. Prior to the release of this feature we have done extensive cross-validation of the Solargis PV simulation model with that of PVsyst and NREL SAM. Whilst there is a good match in results between Solargis and PVsyst for trackers without self-shading (backtracking enabled) there are significant deviations in results for 1-axis tracker without backtracking. For this reason, further validation is required before we support 1-axis trackers without backtracking. If you have access to PV production data that can be used for validation of Solargis model for tracker systems without back-tracking, we would be very interested to hear from you.

Horizon data can now be exported as a .HOR file. This is useful if you wish to simulate energy yield using 3rd party simulation tools.

Information on source of horizon data can be seen here.

PDF and XLSX reports in Prospect app can now be generated also in the following languages:

- Simplified Chinese

- Japanese

- Korean

- Portuguese

- Russian

- French

- Turkish

- New version of economy calculator

- Economy calculator available also in compare tool

- Horizon editor

- Input GOES-East satellite imagery for April 2003 was improved. Previously there were some artificially low irradiance values in some regions such as Chile. This issue has now been fixed.

- Improved zoom and map labels for BING satellite map

- Updated UX for map measurement tools

- Fixes to horizon graph

- Fixed bug in snow losses table/graph. Previously -1 value was shown for months with occasional snow.

- Integrated ERA5 data into our historical time series and TMY

- Better temporal consistency of data

- Satellite map replaced with BING satellite map for improved imagery in many regions

- Distance and area measurement tools included in map window

- reCAPTCHA removed for users from China

- PVOUT CSi map layer was updated.

• Spectral correction considered
• New temperature data source - ERA5
• Updated terrain data
• Soiling losses are now considered before calculation of electric system losses

- Performance of application (loading time) was improved

- Compatibility issues with Firefox/Safari browsers were fixed

- Operational aerosol data harmonization was updated for data starting from Jan 2019.  Solar radiation data for all regions were re-calculated using updated aerosol data.

- The data harmonization is used to control temporal stability of the input aerosol data coming from various versions of models. 

- The biggest changes can be expected for DNI during extreme situations when there was very high or very low AOD (aerosol optical depth).  GHI is also affected but to a smaller extent.
