DESCRIPTION
From a single rooftop to a full solar farm – built in seconds, fully procedural.
Create beautiful solar installations with just a few sliders. This Geometry Nodes generator builds everything you need: panels, mounting structures, sun-following pole trackers, a combiner box and all the cabling. Clean UVs, a lightweight trim texture and smart instancing keep even large solar parks fast and ready to render.
ABOUT THE CREATOR
Hi, I'm Henrik!
By day, I work as a 3D artist for an industrial manufacturer, turning real machinery into product visuals and assembly animations. That everyday experience goes into every asset I make: realistic proportions, clean topology, and tools that make work faster instead of more complicated. I hope this generator saves you as much time as it saves me.
FEATURES
Everything for a solar plant
Flexible arrays
Shape rows, columns, spacing and orientation with live sliders; position and tilt come straight from your plane, every face is one table.
Smart mounting structure
The substructure adapts automatically as your array grows: posts, rafters, braces and bolts, down to the ground or a terrain.
Single-axis pole tracker
Two simple values let your panels follow the sun: pick a sun light or animate one angle.
Wired automatically
A combiner box and the cabling: MC4 jumpers under the panels, string cables tied along rails and posts into the box.
Trim texture and clean UVs
Crisp detail without heavy texture maps, and easy to customize. Or switch to fully procedural materials.
Made for big scenes
Thanks to instancing, hundreds of panels stay smooth in the viewport.
BUILT LIKE THE REAL THING
Every part where it belongs
Datasheet-sized modules with half-cut cells, frames, junction boxes and mounting holes. Strut channel rails through the holes, cold-formed C posts, rafters and braces lapped and bolted, the combiner box on its own rammed post, MC4 jumpers under the frames and string cables tied along rails and posts.

MATERIAL MODE
Procedural or one trim sheet
Every modifier has a Material Mode. Procedural gives one material per part, with the cells drawn by a shader. Trim Sheet maps panels, rails, steel, box and cables onto one 4K texture and one material.

ONE PLANE
Everything starts with a plane
Panels, rails, posts and braces all grow from one plane: move, scale or tilt it and everything follows. The combiner box and the cables are two more empty objects that point at the plane with an eyedropper.

Thanks for checking it out! If you have questions or ideas for new features, just send me a message, updates are always included. And if the generator helps your project, I'd be really happy about a quick rating ;)
QUICK START
Ready in four steps
01
Plane
Solar Array on a plane (every face is one table), pick your Solar Panel with the eyedropper.
02
Mount
Solar Mount below it: Ground Mount (posts to the ground, a terrain or a box bottom) or Pole Tracker.
03
Combiner Box
Place it at the field end, door towards the field; pick the Array, it counts the strings.
04
Solar Cables
Pick the Array and the Box: strings, MC4 jumpers and string cables into every gland.

REQUIREMENTS
Blender 5.2 or newer
No add-on, pure Geometry Nodes
Self-contained, no external files
Designed and built by Henrik Uhrmann. The concept, design and prototypes are handmade in Blender. As a solo creator, I use an AI coding assistant to help me build complex node setups like this one, and every part is reviewed, tested and refined by hand.
