Overview of the Valentin Software Suite

Valentin Software develops specialized design and simulation tools for renewable energy professionals. The suite includes PVSOL for photovoltaic systems, TSOL for solar thermal systems, and GeoT*SOL for heat pump systems. These tools are widely used by engineers, architects, and energy consultants for accurate system planning and performance simulation.

In November 2024, Valentin Software introduced a new user-based rental licensing model for PVSOL premium, PVSOL, TSOL, and GeoTSOL, replacing the previous device-bound perpetual purchase model. This shift provides greater flexibility for professionals working across multiple devices.

Key Features of the Valentin Software Suite

PV*SOL Premium

PV*SOL premium offers comprehensive design and simulation for photovoltaic systems with detailed 3D visualization and advanced shading analysis. The software includes both 3D and 2D shading analysis tools for accurate energy yield predictions.

PV*SOL

The standard PV*SOL version provides core PV system design and simulation capabilities with 2D shading analysis only. It is an excellent starting point for photovoltaic professionals seeking reliable modeling tools.

T*SOL

T*SOL enables detailed design and simulation of solar thermal systems, supporting various collector types and system configurations. The software helps professionals optimize thermal system performance.

GeoT*SOL

GeoT*SOL specializes in heat pump system design and simulation, providing critical analysis for ground-source and other heat pump configurations. This tool is essential for geothermal project planning.

What’s New in the Latest Version

Recent updates across the Valentin Software suite reflect the new licensing model introduced in November 2024. Program versions from 2025 R1 onward support the new user-based rental licensing model.

The latest versions deliver enhanced performance, updated component databases, and improved simulation accuracy. Version details include:

• PV*SOL premium 2026 (R6) – latest trial version available

• PV*SOL 2026 (R6) – latest trial version available

• T*SOL 2026 (R1) – latest trial version available

• GeoT*SOL 2026 (R4) – latest trial version available

System Requirements

The Valentin Software suite requires a compatible Windows environment. For specific system requirements for each program, it is recommended to consult the official Valentin Software website before installation.

Key considerations include:

• Adequate processor and RAM for 3D visualization (particularly for PV*SOL premium)

• Graphics support for detailed shading analysis

• Internet connection required for license activation

Installation Guide

Downloading Trial Versions

Valentin Software provides a straightforward download process for its products. To access the 30-day trial versions of PVSOL premium, PVSOL, TSOL, and GeoTSOL:

1. Visit the official Valentin Software download page

2. Select the desired software product

3. Download the installer for your chosen version

The trial versions include all features except printing and saving the project report. For security verification, SHA1 checksums are provided for each downloadable file.

Software Activation

Valentin Software uses a user-based licensing system requiring online activation:

1. Install the software using the downloaded installer

2. Launch the program and begin the activation process

3. Register and create sign-in details with your email address and password

4. Sign in using your credentials when prompted

5. Activate with your assigned user license

Important: Program versions released from April 7, 2026 onwards can no longer be activated with a perpetual license. Users must transition to the new user-based rental model to continue receiving updates and using newer versions.

Licensing Roles

The new licensing model introduces two key roles:

• License Manager: Manages user licenses in the Valentin License Portal

• License User: Uses assigned licenses for software activation and work

How to Use the Software

Starting a Project

Begin each project by selecting the appropriate system type:

• PV*SOL: Enter site location, select module and inverter types, arrange panels

• T*SOL: Configure collector field and storage system

• GeoT*SOL: Set up heat pump specifications and ground loop design

Running Simulations

Key considerations for simulation:

• Input accurate system parameters

• Use shading analysis tools for PV installations

• Review simulation results carefully

• Refine system design based on output

Exporting and Reporting

The trial version restricts printing and saving project reports. Full functionality is available with a valid licensed version after purchase or rental subscription.

Frequently Asked Questions

What is the Valentin Software licensing model?

Valentin Software introduced a user-based rental model in November 2024. Users rent licenses per person rather than per device, enabling use across multiple devices (though not simultaneously). License Managers control license assignment through the Valentin License Portal.

Can I still use my perpetual license?

Yes, existing perpetual license holders can continue using their purchased software indefinitely. However, the last maintenance contract extensions were offered until October 1, 2024. Program versions released from April 7, 2026 onwards cannot be activated with perpetual licenses.

How do I activate the software?

Activation requires online sign-in with your registered email and password. Your sign-in details are transmitted in encrypted form, and your password is not stored on your computer. User authentication remains valid for a limited period, requiring periodic re-entry of credentials.

Is the software available for Mac?

Valentin Software products are primarily designed for Windows operating systems. Mac users may need to use virtualization or dual-boot solutions to run the software, but official Mac support is limited. Check the Valentin Software website for current platform compatibility.
