ST. ROMAIN, France, Dec 24, 2025 – Trace Software announces the latest features developed in version 2025.1 of archelios PRO, its photovoltaic design software for design offices, installers and developers.
Designed to simulate all types of PV installations, archelios PRO supports professionals in their technical and economic studies, guaranteeing them a smooth, reliable and accurate experience.
This new release consolidates project bankability, improves simulation transparency and strengthens interoperability with our partner solutions. It is also accompanied by multiple corrections and optimisations designed to make photovoltaic studies more reliable.
Importing an Enstall mounting system: saving time and accuracy
The strengthened partnership with Enstall empowers archelios PRO to call the Entall API, allowing a mounting system to be selected and imported directly from the PV layout interface.
Users can retrieve the technical and economic characteristics of the mounting system, automatically integrate it into the material list (BOM), and add the Enstall report as an appendix to the PDF report.
This new integration ensures full compatibility between the mounting system and the project layout, while avoiding manual re-entry or repeated modelling on the supplier’s site.
Benefits:
- Centralisation of all project data in archelios PRO.
- Automatic integration of hardware and costs.
- Saves time and reduces the risk of error.
Customizable probability indicators for even more accurate studies
One of the main advances in this release concerns the management of Pxx probability indicators. archelios PRO can now calculate several production scenarios (from P50 to P95, in increments of 5), in order to assess the production variability and risks.
These indicators, which are widely used in financing analyses, provide users and their clients with a clear understanding of the different return scenarios.
For Platinum users: Visualisation of P50, P75, and P90 probabilities by default, with the ability to display five custom indicators (from P50 to P95).
For Gold users: Visualisation of P50, P75 and P90 indicators.
This data now also appears in the PDF report, increasing the transparency of the study and facilitating its validation by financers and clients.
Benefits:
- Clearly justify the methodology used and inspire confidence in project partners.
- Compare optimistic, realistic and pessimistic scenarios.
- Present reports in accordance with market standards.
New Meteonorm 9 weather data
The weather database has been updated to Meteonorm version 9, released in 2025. This evolution brings more than 4,000 TMY (Typical Meteorological Year) weather stations, offering wider geographical coverage and better data quality.
The new Meteonorm 9 data is now used by default in archelios PRO simulations, ensuring a more accurate representation of real conditions and increased accuracy in production calculations.
Benefits
- Up-to-date and more accurate weather data.
- Improved calculation accuracy.
- Better representation of local conditions around the world.
Revit plugin 2026 compatibility and optimizations
archelios PRO 2025.1 marks a new milestone for BIM integration with a comprehensive update of the Revit plugin. It is now fully compatible with Revit 2026, ensuring the continuity of projects designed in the latest version of Autodesk’s software.
In addition to compatibility, in-depth performance optimisation work has been carried out to improve the fluidity of the export to archelios PRO web, especially for large or complex projects.
Export times have been reduced and file management simplified, for a faster and more stable workflow between the BIM model and PV simulation.
Benefits
- Compatibility with Revit 2026 and modern workflows.
- Smoother and more robust export of large projects.
- Time savings and increased reliability in BIM–PV continuity.
Also in this version:
- archelios plugin compatibility with SketchUp 2026
- Addition of new ELMAS* consumption profiles based on 55,000 real measurements and 18 standard hourly profiles for more accurate industrial and tertiary simulations (France).
- Option to display or hide the low voltage switchboard in the simplified single-line diagram, for a more representative schema in full injection configurations.
- More than 30 corrections and improvements to improve the stability, usability and speed of the application.
