What Is PV*SOL?

Developer & Background:
PVSOL is a professional photovoltaic simulation software developed by Valentin Software GmbH, a Berlin-based company established in 1988. With over three decades of experience, Valentin has become a trusted name in PV system design, known for its emphasis on engineering-grade accuracy and technical depth. PVSOL is widely used across Europe and internationally by engineers, EPCs, system designers, and researchers.

PV*SOL is offered in multiple editions to suit varying technical needs and budgets:

  • PV*SOL Premium: The most advanced version. Includes full 3D visualization, detailed shading simulation, terrain modeling, and complete electrical configuration. Ideal for complex residential, commercial, and utility-scale projects.
  • PV*SOL Standard: Offers the core simulation engine but excludes 3D design tools. More suitable for early-stage system evaluations or simpler sites.
  • PV*SOL Online: A free, browser-based tool for basic performance and yield checks. Useful for preliminary estimates but not meant for proposal-grade accuracy.

The software is tailored for technical professionals—including solar engineers, consultants, academic researchers, and EPCs—who need detailed performance simulations, bankable energy yield forecasts, and loss factor transparency.

Originally launched in 1998, PV*SOL has evolved through more than eight major versions. The 2025 editions feature:

  • Updated meteorological datasets
  • Expanded inverter and module libraries
  • Enhanced 3D terrain tools
  • Improved LCOE and payback modeling
  • UI performance and visualization refinements

Its legacy and precision make PV*SOL a go-to tool for those prioritizing accuracy and depth over simplicity or design speed.

Key Features of PV*SOL (2025 Edition)

3D Shading & Terrain Modeling

PV*SOL Premium offers a highly detailed 3D design environment that supports advanced shading analysis. Users can model buildings, trees, terrain contours, and other obstructions with precision. Import options include LIDAR, CAD files (OBJ, DAE), and digital terrain models. The animated sun-path visualization enables hour-by-hour irradiance assessments across the year, critical for shading-sensitive installations.

Electrical Configuration

The software includes robust auto-stringing tools with flexible options for poly-string layouts. Users can configure string lengths, inverter MPPT channels, and system voltages, while simultaneously analyzing electrical losses due to current mismatches, DC cabling, and inverter efficiency. Outputs include full DC/AC schematics and yield curves per configuration.

Weather Data Integration

PV*SOL comes preloaded with global irradiance data from Meteonorm, PVGIS, and NASA-SSE, while also allowing the import of site-specific meteorological files (e.g., TMY, CSV). This ensures climate-specific accuracy for any project location.

Performance Simulation & Loss Diagrams

Simulates PV system performance with 8,760-hour resolution. Outputs include:

  • System yield (kWh/kWp)
  • Monthly breakdowns
  • Loss factor waterfall diagrams
  • IEC 61724-compliant Performance Ratio (PR) metrics

These simulations are considered bankable and are widely accepted in technical and financial documentation.

Financial Modeling

Advanced financial simulation tools are embedded, including:

  • Levelized Cost of Electricity (LCOE)
  • Return on Investment (ROI)
  • System payback time
  • Tariff modeling (fixed, stepped, time-of-use)
  • Feed-in premiums, grants, and inflation tracking

This enables users to build incentive-compliant scenarios for both residential and commercial systems.

Battery & Load Modeling

PV*SOL allows in-depth simulation of self-consumption, energy storage, and time-of-use strategies. Users can define load profiles, storage sizing, cycle limits, battery aging, and charge/discharge logic—essential for hybrid and backup system scenarios.

CAD Integration

Full compatibility with DXF, 3DS, DAE, and PVC files makes it easy to import architectural or terrain data. The PhotoPlan tool lets users create basic rooftop geometry by tracing from aerial photographs or scanned images.

Output Reports

Generates comprehensive documentation:

  • Custom-branded Word and PDF files
  • Configurable multi-language templates
  • Graphical layouts and loss diagrams
  • CSV or Excel data exports for engineering or compliance teams

These reports are ideal for both client presentation and permitting.

User Experience & Interface – PV*SOL (2025)

Deployment

PV*SOL is a Windows-only desktop application, requiring local installation. It does not support macOS or Linux systems natively, meaning Mac users must rely on virtualization tools like Parallels or Boot Camp. There is no browser-based or mobile version, which makes it less flexible for remote teams or field use.

User Interface

The interface is function-focused but visually dated. The UI prioritizes control and technical flexibility over aesthetics, which may appear overwhelming for first-time users. Menus are dense, icons are not always intuitive, and settings are buried within submenus. However, once mastered, the software offers granular control over every simulation parameter—from electrical topology to meteorological imports.

Speed & System Requirements

While PV*SOL is highly accurate, it is also resource-intensive. Large-scale simulations (e.g., >7,000 modules or multi-inverter systems) can lead to notable performance slowdowns, especially during 3D rendering or hourly yield simulation. The software benefits from high-RAM setups (16 GB+), dedicated graphics cards, and multi-core CPUs. Without this, design workflows and export times can lag.

Learning Curve

PV*SOL has a steep learning curve, particularly for users unfamiliar with solar modeling terminology or engineering workflows. Detailed configuration settings, multi-tab interfaces, and nested menus make it more complex than cloud-based alternatives. However, Valentin Software provides robust learning support, including:

  • Step-by-step PDF and video tutorials
  • Webinars (in German and English)
  • A searchable knowledge base
  • User forums for peer support

New users should expect to invest 5–10 hours of self-guided training before becoming proficient with basic simulations.

Workflow Suitability

Despite its complexity, PV*SOL excels in structured engineering environments, especially for:

  • Large rooftop systems
  • Utility-scale ground mounts
  • Battery-integrated residential/commercial sites
  • Feed-in tariff planning under EEG regulations

It handles grid-tied, self-consumption, and hybrid systems equally well, making it a top choice for EPCs needing high-accuracy simulations over aesthetic presentation.
