Built for utility-scale solar

From a site boundary to a buildable, costed layout — in minutes.

SolarCAD places every table or tracker inside your boundary, groups them into ITS stations, positions the string combiner boxes, routes the cabling along roads and trenches, pools the substations, and hands you a DXF drawing set and a bill of quantities. The kind of work that takes a design engineer days.

A utility-scale solar plant laid out in SolarCAD: tables grouped into colour-coded ITS zones, internal roads, string combiner boxes and routed cabling.

Everything a layout needs, in one pass

Not a rooftop tool. SolarCAD is built for ground-mount plants where the hard part is not drawing panels — it is the grouping, the cabling and the quantities.

▦

Placement that respects the site

Fixed tilt or trackers, full and half tables, road grids, periphery ring road, setbacks and no-table zones. Rows are held strictly inside the boundary, including concave corners.

⚡

Electrical design, not just geometry

ITS grouping to your AC capacity, SCB placement packed to your strings-per-box limit, and cabling routed along roads and trenches — never across a table.

▤

Quantities you can price

An Excel workbook down to per-ITS, per-SCB and per-table detail, with cable lengths taken from the routes actually drawn, not estimated.

⛰

Real terrain

Import a DEM, georeferenced against your KML site. Slope banding shows what is buildable; drop everything above a threshold and see the capacity cost immediately.

☀

Shadow analysis

The 21 December, 9am–3pm criterion: the window your row pitch actually achieves, the pitch it needs, and which rows your ITS stations and substations shade.

▣

Several parcels, one plant

Import multiple boundaries and lay each out independently, with substations pooling across parcels and cabling routed between them.

How it works

Four steps. The whole loop is fast enough to try three layouts before lunch.

Bring in the siteImport a DXF (with your layer names) or a KML/KMZ, or draw the boundary. Exclusion zones and survey geometry come with it.
Set the system and fillModule, orientation, strings, tilt, row pitch, road grid. Press Fill and the plant appears with its capacity.
Add the electrical designITS stations, SCBs, cabling and substations. Drag a station and everything downstream re-routes and re-costs.
ExportA layered DXF for the drawing set and an Excel BOQ for the estimator.

What you hand over

Output your drawing office and your estimator can use directly.

DXF drawing

Boundary, exclusion zones, setback, internal and periphery roads, every table or tracker on its own ITS layer, SCB boxes with tags, ITS stations, substations, cable runs and slope bands — each on a named layer you can freeze and thaw.

Excel bill of quantities

Plant summary, per-ITS capacity, per-SCB detail, and a hierarchical ITS → SCB → table sheet with tags, configuration, modules, kWp and cable lengths for every run.

The exported DXF drawing open in CAD, with each ITS zone on its own layer.
