Valentin Software addresses the technical challenges of planning and simulating renewable energy systems, specifically focusing on photovoltaics, solar thermal, and heat pumps. For over three decades, the company has provided engineers, installers, and system designers with tools to predict energy yields, perform economic feasibility studies, and visualize system layouts in both 2D and 3D environments.
Professionals consider Valentin Software because its products, such as PV*SOL and T*SOL, combine high-precision climate data with extensive component databases. These tools help reduce the uncertainty in solar projects by providing accurate performance simulations that account for complex shading, self-consumption patterns, and battery storage integration.
What Is Valentin Software?
Valentin Software is a provider of dynamic simulation and design software for the renewable energy sector. Its flagship product line includes PV*SOL (photovoltaic simulation), T*SOL (solar thermal design), and GeoT*SOL (heat pump planning). The software serves as a comprehensive platform for technical planning, allowing users to transition from initial site assessment to detailed technical reports and financial forecasts.
The primary target users include solar engineers, EPC (Engineering, Procurement, and Construction) companies, energy consultants, and installers who require verifiable data to support their project proposals. The platform works by combining local meteorological data with specific hardware parameters—such as inverter efficiency curves and module power ratings—to simulate real-world system behavior. Valentin Software is recognized as an industry leader in Europe and beyond, with a history of software optimization dating back to 1998.

How to Set Up Valentin Software
- Download the trial or purchased version from the Valentin Software official website.
- Install the software on a Windows-based PC (system requirements should be checked for 3D features).
- Activate the license using the credentials provided via email (activation typically takes 1–2 business days).
- Configure regional settings, including preferred units of measurement and default currency.
- Update the product database to ensure you have the latest module and inverter specifications.
- Select your first project location to download the necessary climate and meteorological data.
How to Use Valentin Software
The standard workflow begins with selecting a project location and climate data set. Users then define the type of system—such as grid-connected, off-grid, or battery-backed. In the design phase, users either use 2D photo-plan tools or the 3D environment to place modules on a roof or ground area, accounting for obstructions that might cause shading.
Once the layout is set, the software assists in component selection by suggesting compatible inverters and string configurations. Users then input load profiles (electricity consumption patterns) to simulate how much solar energy will be used on-site versus exported. The final step involves running the dynamic simulation, reviewing the results, and generating a comprehensive project report that includes technical data, yield diagrams, and economic analysis.
