# 20250916 v 2.5.0

### Application release notes

> [!WARNING]
> **Important**: Please note that not all newly released features are guaranteed to be backward compatible; in some cases, adjustments to existing projects or re-simulation may be required to ensure full functionality.

| Release date | Software version |
| --- | --- |
| 16.9.2025 | 2.5.0 |

### General

- Federated identity provider (IdP) integration is rolling out, enabling customers with enterprise accounts to use their own IdP (e.g., Google Workspace, Okta) for authentication.
- Multi-factor authentication is now supported.
- Overall platform performance has been improved, and several action buttons have been relocated more consistent workflows.
- Home, Prospect, and Evaluate project managers are now more unified in both features and design.
- Users can now archive multiple projects at once.

### Prospect

- The design and behavior of the project manager is now aligned with Home and Evaluate for a unified user experience.
- “Country” has been added as a new column in the project list.
- Marking multiple projects on the map is no longer supported.

### Evaluate

- Download functionality for Reports & Exports has been redesigned to better handle strict network security settings commonly used by corporate customers.
- Evaluate now supports multiple data sources:
  - Users can request the latest Solargis data version for their projects.
  - Data sources can be viewed and requested on the Project data screen (Figure 1).
  - Selected data sources are available for running new simulations.
  - Different data sources can be used in the Energy System selector and ES list.
  - Reports and Exports can now reference selected data sources.
- PV exports now use 15-minute data resolution by default.

**Energy system designer**

- Monthly and yearly time series charts have been introduced to the snow and soiling losses (Figure 2).
- Restricted areas and restricted lines now follow terrain for more accurate layout design (Figure 3).
- Restricted areas now support buffer zones, improving flexibility when defining no-build regions.
- PV module filtration criteria have been updated, offering users more precise control when selecting modules.
- The application now prevents accidental closing of the tab during project work to protect user progress.
- The time slider now allows selection of a 1-minute time step, enabling finer resolution for shading analysis.
- All ESD export files are now generated with proper filenames for easier identification and management.
- Bill of Materials (BOM) can now be generated even if the Solargis model for soiling or snow is invalidated.
- Interactive BOM data—including prices and custom items—are now included when exporting the BOM to XLSX format.
- Resolved an error that occurred when editing restricted lines.

**Reports & exports**

- Uncertainty is now supported in reports for projects where Uncertainty data was provided.
  - Chapter 1 (Summary) now displays Uncertainty data.
  - A new Chapter 8 (GHI and DNI uncertainty, probabilities of exceedance) has been introduced.

**PV simulator**

- The Transient thermal correction model is now also used for 15-minute data simulations.
- Soiling losses on the rear side of a bifacial module are calculated as 15% of the soiling losses applied to the front side.
