Location:Romania
Market:Renewable Energy / Engineering
Specialties: PVCAD
Project Focus: C&I Rooftop & Ground-Mount
Key Impact: 50% reduction in drafting time

Challenge: Before PVCAD, TIAB relied on manual drafting in standard CAD software. Engineers spent significant time placing solar modules, creating electrical string layouts, and updating designs. Even minor changes often required rebuilding large sections of the drawings.

Solution: PVCAD combines AutoCAD-level precision with built-in solar automation, allowing TIAB’s engineers to stay in their familiar CAD environment while automating module placement, electrical stringing, and component selection—reducing design time without compromising accuracy.

Mechanized line drawing and manual routing are a thing of the past. PVCAD is the essential bridge between professional engineering and solar-specfic automation.

TIAB Design & Engineering Team

The Challenge

Before implementing PVCAD, TIAB’s renewable energy design team relied on manual engineering work performed in conventional CAD environments with limited automation capabilities. Designing photovoltaic systems required engineers to individually position the solar modules, define electrical string configurations, and develop cable routing layouts across complex industrial rooftops and diverse ground-mounted installations.
This approach demanded significant engineering effort and extended drafting cycles, particularly for large-scale projects. Any design modification—whether driven by client requirements, technical optimizations, or changes in equipment specifications—often required substantial portions of the layout to be recreated manually. As a result, design updates were time-consuming.

The PVCAD Solution

TIAB adopted PVCAD because it naturally blends professional AutoCAD-level drafting accuracy with purpose-built solar automation. Instead of migrating engineers to separate standalone modeling packages, PVCAD allows TIAB’s design team to remain completely within their native, precision-focused CAD workspace while adding automated tools tailored specifically for module placement, rapid electrical stringing, and component sourcing.
  • Automated StringingInstantly maps circuit strings and layout wiring setups, removing hours of manual line drafting.
  • AutoCAD-Native ArchitecturePreserves complete drafting precision and technical drawing layers required for municipal permitting approvals.
  • Global Equipment DatabaseEnables instantaneous component updates, allowing engineers to load exact electrical tolerances within the file.
  • Dynamic IterationsModifies pre-mapped module matrices automatically when layout geometries or client requirements shift.

Results & Impact

The integration of PVCAD immediately enhanced design efficiency across TIAB’s solar business. On standard multi-building installations and multi-megawatt ground layouts, the engineering team recorded an average 50% reduction in technical drafting and electrical stringing times compared to traditional practices.
  • 50% Time Reduction Drafting and line-stringing tasks completed in half the time on 1MW+ systems.
  • Rapid Client Iterations Re-evaluating or scaling layouts takes minutes instead of reconstructing entire drawings.
  • High Standardization Produces clean, uniform CAD templates optimized for strict municipal and parent group reviews.
  • Strategic Resource Focus Shifts professional engineering hours away from placing drawing blocks toward project layout optimization.

Why TIAB Recommends It

TIAB highly recommends PVCAD to technical teams and solar installers seeking to increase engineering capacity without inflating drafting headcount. By using an existing AutoCAD base layer, the platform guarantees that companies retain complete control over precision technical tolerances while eliminating the slow, manual procedures historically tied to commercial solar development.
