Solar Design Software

Solar design software
for utility-scale projects

PVX.Cad is AutoCAD-native solar design software that starts with terrain, not layout. Grading analysis, cable routing with voltage drop, and construction-ready exports from one file. Built for engineers designing utility-scale PV plants on real topography.

Solar design software is the engineering platform that takes a utility-scale photovoltaic project from terrain data to construction documentation. It covers panel layout, grading analysis, cable routing, and export to formats like DWG, LandXML, and PVsyst. The category includes cloud-based PV design software, standalone solar panel design software, and CAD-integrated tools. What separates them is how they handle terrain. At utility scale, terrain is not a background layer. It is the primary cost driver.

What separates utility-scale from simple layout tools

Most solar design tools were built for speed: drop panels on a flat surface, run basic electrical, export a report. That works for small systems. At utility scale (10 MW and above), terrain variation, grading costs, and cable lengths determine whether a project closes its budget or blows it. Three gaps show up repeatedly.

Disconnected workflows

Terrain data gets exported from CAD, processed in a separate PV design tool, then manually transferred back. Every handoff introduces version mismatches and rework. Civil and electrical design run in parallel instead of in sequence.

Terrain simplification

Cloud-based solar planning software compresses your survey data to run on remote servers. Full-resolution detail from LiDAR or drone photogrammetry gets lost before grading analysis even starts. The design assumes a simpler site than exists.

No construction-ready outputs

The photovoltaic design software produces a layout and a bill of materials. Construction needs native DWG files, pile coordinates, grading contours, cable schedules, and LandXML for civil contractors. That gap is filled manually.

What PVX.Cad does differently

Terrain analysis before layout

Reconstruct a grid surface from your terrain data at configurable resolution. Slope classification and soil hardness mapping run before a single row is placed. You see where earthwork costs concentrate before committing to a layout.

Three grading approaches compared

Full-terrain smoothing, pile-adaptive grading, and table splitting with real cost calculations side by side. Choose the right approach per zone instead of defaulting to mass grade. One project reduced earthwork from 118,000 m3 to 35,000 m3 this way.

Cable routing optimization with voltage drop

Automated routing for Line, U-String, and Leapfrog topologies. Voltage drop calculated per string, per cable cross-section. Compare topologies on total cable length, material cost, and electrical loss. On a 130 MWp project, topology choice alone saved $430K.

Construction-ready exports

Native DWG for construction, LandXML for civil contractors, PVsyst-compatible data with module positions for bankable yield simulation, CSV schedules for procurement. All generated from one AutoCAD file. No manual translation between design and IFC documentation.
