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.
Build-Ready Solar Design
Design solar projects with terrain, shading, electrical, and construction constraints integrated from day one. Catch issues early, reduce redesign later, and generate outputs ready for planning and construction.
Automate Complex Solar Engineering
Accelerate layouts, stringing, cable routing, and engineering calculations with connected workflows that reduce repetitive work and speed up project delivery.
Design-to-Construction Alignment
Connect solar layouts, engineering data, materials, and project outputs in one workflow to reduce mismatches, improve planning accuracy, and keep projects aligned from design to construction.
Analysis
Shadow Analysis
Evaluate solar shading impact with time-based simulations that account for surrounding buildings, terrain, and site obstacles. Identify high-impact shading areas early and optimize PV layouts for real-world site conditions.
Electrical
Automated String Plans
Design and adjust string configurations to match rooftop layouts and electrical constraints.

Frequently Asked Questions
Virto.CAD is designed for EPCs, engineering firms, and solar developers working on commercial, industrial, and utility-scale PV projects. Click here to learn more.
In order to use Virto.CAD, your PC needs to meet specific system requirements:
- Graphics hardware requirements for AutoCAD
- System Requirements for AutoCAD
- System Requirements for BricsCAD
If you need any assistance, please contact our support team.
No, it’s not possible to use an onboard graphics card since this will not guarantee a good performance. An integrated onboard graphics card is a card that does not have its own CPU, but rather is using your system’s RAM and system CPU to get the visuals out that you require. Please check this website to find a certified graphics card.
Yes, you need either AutoCAD or BricsCAD.
Current compatible versions include for BricsCAD include Pro, BIM, Mechanical and ultimate; for AutoCAD versions 2024-2026, Civil 3 and, Map 3D. Please note Virto.CAD is not compatible with AutoCAD LT and BricsCAD Lite.
