Compatible with Virto.CAD
Once the investment decision is made, the project can be exported to DWG for further development in CAD tools, avoiding the need to restart from scratch. This preserves the work done in Virto.MAX, saves time, and enables a smooth transition from design to detailed engineering.
Export to PVsyst

- Accelerate bankable reporting with PVsyst-read file formats
Consumption Data Upload
Upload electricity consumption data to compare energy production and consumption in one place, giving you deeper insights into system performance and self-consumption.
- Analyze production and consumption with interactive daily and yearly charts
- Include production and consumption metrics in stakeholder-ready project reports
Simplified CAPEX for financial modelling
Simplify financial modeling with a streamlined CAPEX workflow using average cost per kWp, while keeping detailed cost inputs available when needed.
- Estimate CAPEX quickly with a simplified price-per-kWp input
- Switch to detailed cost breakdowns for advanced financial planning
Roof Remodelling
Edit and refine building models without disrupting your PV design, making it faster to iterate and adapt projects as they evolve.
- Modify roofs and building heights without removing panels or inverters
- Iterate on building designs while preserving existing PV layouts and components
Use Google Maps and Image Underlay
You can select an underlay as the base for your drawing, either from Google Maps or by uploading your own (PNG, JPG, or PDF).
Shareable 3D Links
Share interactive 3D project models with customers and stakeholders through a secure, customizable link for easier collaboration and project reviews.

Gain accurate insight into system performance using real site and design data. Simulate energy yield, understand production and consumption, and seamlessly export results to PVsyst.
PVsyst & CAD export
Bridge the gap between design and delivery with a connected PV workflow. Collaborate with your team through shared project access, win over stakeholders with brandable reports, and streamline engineering with frictionless .DWG exports and PVsyst-ready data.
Electrical Configurations
Design and configure complete PV Systems with clear, sales-ready outputs that support presentations and decision-making.
- Configure inverters, estimate cable sizes and lengths and evaluate string distribution
- Design and size battery systems as part of the overall configuration
Battery Sizing & Placement
Design and size battery systems with confidence
- Define input parameters and select preferred battery models to generate optimal sizing
- Place batteries at suitable on-site location based on project layout
3D Modeling and Automated Layout
Create accurate 3D site models and generate optimized PV layouts in one workflow.
- Model roofs, terrain, and obstacles with precise 3D site representation
- Automated layout for rooftop, carport, and ground systems
- Advanced layout control, including shading and thermal breaks
- Automated building generation from drone imagery and point clouds (via Virto.RISE)
Customize Branding & Report
You can customize reports with your logo, brand colors, and links, creating professional outputs that match your company identity.
Create Teams and Share Your Projects
You can create teams to collaborate with colleagues, where projects are automatically shared with all members for easy access and continuity, even during absences or handovers. Projects outside a team can still be shared, but this requires manual sharing.
Customize Thermal Break Positions
You can adjust thermal break positions to better match design requirements. This helps keep obstacles accessible, avoids small panel fields with high roof point loads, and improves layout quality and aesthetics.
Detect Obstacles Automatically
After drawing the first obstacle, the platform automatically identifies similar roof obstacles based on the matching accuracy you set.
Offered in Metric and Imperial
We support both metric and imperial unit systems.
Convert Drone and LiDAR Scans to 3D Models [BETA]
Based on drone footage, Virto.MAX can generate an accurate 3D model of the project site. This provides a reliable, real-world basis for design, making subsequent planning steps more precise.
Create Designs for Any PV Project Without Sizing Limitation
Virto.MAX supports large-scale PV layouts with over 150,000 panels across multiple buildings or surfaces, while maintaining stable performance.
Automated Module Layout
Generate optimized PV layouts faster with intelligent placement tools designed for real-world solar projects. Adapt layouts to terrain, obstacles, and site constraints while refining module spacing, orientation, and system configuration with flexible design controls.
