of solar professionals report that more than a quarter of their designs require significant revision. On ground-mount sites with complex terrain, the root cause is always the same: layout-first tools that treat slope, rock, and drainage as afterthoughts. The redesign happens at construction, when it costs the most.

Stop Redesigning Ground-Mount Projects at Construction

Most tools optimize panel layout on a flat plane, then hand the terrain to civil engineering. That sequence costs real money on sloped sites.

Late-Stage Terrain Surprises

Rock formations, steep slopes, and drainage issues appear after the layout is locked. The civil team inherits problems that should have been visible at design stage. By the time grading estimates arrive, redesign is the only option.

Rework from Layout-First Tools

Layout-first tools place panels on an idealized surface, then check terrain afterward. The result: rows that conflict with slope limits, pile locations that hit rock, and grading plans that do not survive construction review.

Earthwork Cost Overruns on Sloped Sites

Full terrain smoothing on a site with 44% hard rock cost $1.06M. A terrain-aware approach on the same site: $335K. The difference is not engineering talent. It is which information the designer had when they started.

PVX.Cad: Terrain-First Ground-Mount Design

Analyze the actual terrain surface before layout. Understand slopes, soil hardness, and grading cost before placing a single panel.

Slope Analysis

Map Every Gradient Before Layout

Import LiDAR, contour surveys, or topographic surfaces into AutoCAD. PVX.Cad maps slope distribution across the full site envelope, flagging zones above tracker tolerances before any row is placed.

Soil Hardness

Know the Substrate Before the Bulldozer Does

Seven-class soil hardness classification identifies rock, clay, and mixed substrates. On one project, 44% of the site was very hard rock. That classification changed every grading decision that followed.

Multi-Scenario Grading

Compare Three Approaches in Minutes

Full terrain smoothing, pile-adaptive local grading, and table splitting. PVX.Cad evaluates cut/fill volumes and cost for each approach on the same site. One grading method is a guess. Three compared is a decision.

Construction Outputs

From Terrain Surface to Build Package

Pile coordinates, grading plans, cross-sections, cable routes along real trench corridors, and clean PVsyst export. Construction-ready outputs from the same AutoCAD file your team already works in.

One Site. Three Grading Approaches. $727K Difference.

A ground-mount site with 44% very hard rock and slopes reaching 40-45%. Traditional full-terrain smoothing vs. terrain-first design.
