[Generated by AI Assistant] Date: April 14, 2026 Abstract The rapid expansion of utility-scale solar photovoltaic (PV) installations demands specialized design tools that transcend the limitations of generic computer-aided design (CAD) software. While Autodesk’s AutoCAD remains the industry standard for drafting and design, it lacks native features for terrain-aware PV layout, automated cable management, and topographic shading analysis. This paper examines PVcase , a third-party plug-in that operates within AutoCAD, transforming it into a dedicated PV engineering environment. The study analyzes PVcase’s core modules—Array Layout, Terrain, Cable Management, and Roads & Trenches—and evaluates their impact on design accuracy, time efficiency, and inter-disciplinary collaboration. Results indicate that PVcase reduces design time by up to 60% compared to manual AutoCAD methods, minimizes topographic shading losses, and automates Bill of Materials (BOM) generation, thereby establishing a new benchmark for solar project lifecycle management. 1. Introduction The global shift toward renewable energy has accelerated the development of utility-scale solar farms exceeding 100 MWp. Engineers face three persistent challenges: (1) designing on uneven terrain without excessive earthworks, (2) minimizing shading losses between tracker rows, and (3) managing the complexity of DC cabling and combiner box placement. pvcase autocad

AutoCAD, first released in 1982, provides a robust foundation for 2D and 3D drafting. However, its generic toolset forces PV designers to manually calculate row spacing, draw thousands of tracker blocks, and estimate cable lengths—a labor-intensive, error-prone process. PVcase emerged in 2017 as a response to these inefficiencies. By operating as a native AutoCAD plug-in, PVcase retains the familiar CAD interface while adding PV-specific intelligence. This paper argues that PVcase does not replace AutoCAD but elevates it into a purpose-built solar design platform. PVcase integrates through a dedicated ribbon menu inside AutoCAD. Its primary modules are: | Task | Manual AutoCAD (hours) | PVcase
