Application release notes
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 |

21.06.2026 | 2.8.0 |
General
The Company admin has changed to Customer admin and has moved from the applications menu to the user menu (the avatar circle showing your active customer name), keepinccount management separate from app navigation (Figure 1).
Token names and token generator emails are now displayed in all tables in the administration section (API) where token lists and token usage are displayed.
Prospect
Hail days and Soiling loss for GTI Opta systems data layers have been added to Prospect (Pro & Enterprise).
New data is visible across the whole Prospect application (map layers, data, metadata, glossary, compare)
New data is currently not included in the Reports and Exports.
Evaluate
When duplicating or creating a new Energy system, the application now suggests a unique name automatically, helping you avoid naming conflicts.
The Data source selector on the Uncertainty page now handles missing uncertainty data more gracefully: if no uncertainty analysis has been delivered for the selected data source, you'll see a direct option to request it.
Reports & exports
Column selector settings in Data exports and the Reports table are now persisted across sessions, so your preferences are restored automatically on your next visit.
The Reports table now displays the full report name, giving you more context at a glance.
The PV Export column selector has been reordered to follow the simulation losses chain, making it easier to find and select the columns you need.
The solar & meteo exports now contain Dew Point Temperature (TD) and Wet Bulb Temperature (WBT) for TMY exports and Cloud Index flag (CI_FLAG) for 1-minute Time series exports.
Energy System Designer
C&I rooftop systems: Let you define roof planes, draw segments, add arrays, and simulate — with obstacle management (HVAC, skylights, shafts), string overflow mode for denser packing, a map-based azimuth tool, and a hard DC capacity limit (Figure 2).
Export to DXF: Lets you export your layout as a CAD-ready DXF file with objects organized by layer, attributes preserved, and your choice of coordinate reference system (EPSG code).
Soiling & snow loss improvements: Let you schedule cleaning events by day of the month, choose from cleaning method presets or define your own, and set night and snow-stowing angles for single-axis tracker arrays (Figure 3).
Undo & redo: Now supports up to 100 steps in either direction, works globally across the design and locally within drawing and editing tools, and removes deletion confirmations — undo is the safety net (Figure 4).
Energy system recovery: Automatically offers to restore your previous session if a tab crashes or reloads.
Specify inverter count & evenly distribute strings: Lets you set a fixed inverter count and distribute strings evenly across inverters and MPPT inputs, with clear feedback when a perfect balance isn't possible.
More helpful system validation: Now explains each failed check in plain terms, links to documentation, and runs in real time after each design action (Figure 5).
Clearance height redefinition: The spacing panel now includes an info dialog that explains the height parameters.
Improvements and bug fixes
The DC/AC ratio field now supports more decimal places.
Mounting type have been removed from the segment level; replaced with a direct link to the array.
The DC capacity limit can now constrain the layout to a target installed power.
The maximum grid connection voltage has been increased to 500 kV.
Unconnected PV elements are now hidden in the 3D scene.
Added 5% voltage tolerance for transformers connected directly to the grid connection.
Supporting structures are now hidden for plants exceeding 50 MWp.
Missing user feedback when the inverter unit count exceeds available strings have been fixed.
Inverter exclusion zone now accepts decimal values.
Tracker rotation limits now consistently reference the horizontal plane.
Table size information has been unified across summaries.
Spacing panel now includes an info dialog explaining height parameters.
Confirmation dialogs have been removed (replaced by undo/redo).
Fixed the Unsaved changes dialog now appearing when creating a new energy system without making any changes.
Fixed the Unsaved changes dialog now appearing after renaming an energy system and using the Save and close option.
Transformer overlapping with modules has been fixed.
