Home SolarGround mount

Ground-mount solar, laid out inside AutoCAD.

Utility-scale plants from the satellite map to the bill of quantities: terrain, arrays, strings, cables, trenches and the drawing set. It's where we've built the most.

Highlights

Every step of a plant layout, in one drawing.

A few highlights from the tools we build for solar teams. Every picture shows a real result from AutoCAD, except the good-for-construction (GFC) concept.

Layout

Array creation

From the site boundary to a full array. Set the fence, setbacks and periphery road, place the lightning arresters, then fill every PV area with frames. A live preview shows the result before a single frame is placed.

Fence, setbacks and a rounded periphery road from the site boundary
Internal roads from centrelines you sketch, with set-out points
Lightning arresters placed first, so frames stay out of their shadows
Fixed-tilt and tracker frames, up to four sizes mixed

Standard or adaptive placement, filled to the boundary
Maintenance corridors, with a road down the middle if you need one
Road coordinates and street lights, each with their coordinates
A project summary of frames, modules and capacity

Operations

Cleaning robot analysis

Works out how module-cleaning robots travel along the rows. Frames in a row join into one robot run where the gaps are small enough to bridge. Longer runs get their own automatic robot, and short runs share a semi-automatic one moved between rows.

Automatic robots counted for each length range
Semi-automatic robots grouped for short runs
Each run coloured by its length
A row-length label on every run

Docking and reversing stations at the run ends

Earthing

Earthing layout

Lays out the DC earthing of a fixed-tilt PV area: tables bonded pile to pile, and rows linked by strips in the column gaps.

Two side and one side risers, with row links and collectors
DC earth pits at about one per MWp
Combiner boxes strapped to the grid along the trenches
Two earth pits for every lightning arrester

Strips stay inside the PV area and never cross a table

Electrical

Electrical grouping

Places the ITCs and groups their inverters, then groups the strings into combiner boxes, by hand or automatically.

ITCs placed on the site, with shorter frames filling the room left
Automatic combiner box grouping, with options to compare
An outline and a station block for each group
A tag on every string, such as ITC1-INV2-CB3-S4

Rows of tables with a tag on every string, such as ITC1-INV1-CB7, and combiner box blocks between the rows — 1Strings grouped into combiner boxes, each group in its own colour

Electrical

Cable generation

String cables run from every string to its combiner box, and DC cables from every combiner box to its own inverter, round the frames and along your guidelines. Cables of two inverters never share a trench.

Red (+) and blue (−) string cables in lanes
Daisy chain or leapfrog stringing
Conduits across narrow table gaps and into the combiner box

Coloured combiner box groups with the DC cable routes running through them to each combiner box — 1String cables along the purlins, and in one bundle to the combiner box

Civil

Trench generation

Draws the DC cable trenches along the cables. Each stretch of inverter trench is sized by how many cables share it, from your own section table.

Sections A, B, C… as hatched bands with centrelines
Each section's width set by the cables inside it
String cables share the inverter trench, or get their own

Civil

Grading

Grades a PV area, or a whole site with all its PV areas and roads, in one run. It finds the finished ground with the least earthwork within your limits, then sets every frame on it within its own structure limits.

FAQ

Questions solar teams often ask.

Anything else, just ask in your enquiry.

Which CAD versions does it run on?

AutoCAD 2021 to 2027. We've also built tools for ARES Commander and BricsCAD, so tell us what your team uses.

Does it handle both fixed-tilt and trackers?

Yes. Array creation places fixed-tilt and tracker frames, with up to four frame sizes mixed, and grading sets each frame within its own limits. The earthing layout is built for fixed-tilt areas.

Can we start from a Google Earth file?

Yes. Import a KML or KMZ file and its points, lines and polygons are drawn at their real position, on layers named after the placemarks. If the drawing has no location yet, it gets one from the file.

Can it work with our own frames and standards?

Yes. You set the frame sizes, pitch, row spacing and corridors, and the trench sections come from your own table. If you need something it doesn't do yet, that's the work we do: we build CAD tools around a team's standards.

What happens when the layout changes?

Run the tool again. Its earlier result in that PV area is replaced, not added to. Each later tool reads what the one before it drew, so you run them again in turn.

Can it handle a site with several PV areas?

Yes. Pick the site boundary instead of one PV area, and tools such as cleaning robots, cables, trenches and earthing cover every PV area of the plot in one run.

What do we get at the end?

A drawing with every layer in place, plus tables and Excel files: cleaning robot and earthing BOQs, cable schedules, a pile schedule, trench and earth pit coordinates, the project summary and a single-line diagram. The layout can also go out as KML for Google Earth.

Can we see it working on our own site?

Yes. Send us a site boundary or a sample drawing and ask for a demo. We're happy to sign an NDA first.

Have a plant to lay out?

Send us the site boundary and your design rules. We'll reply with an approach and a fixed quote.
