Terrain & layout
Import TIN, DEM, contours, or GIS and place strings on real terrain.
AutoCAD extension · Solar
From site surface to sales-ready proposal
ELAP turns TIN, DEM, contours, or GIS data into a project base inside AutoCAD: real terrain, boundaries, exclusions, and DWG geometry.
One plugin
The whole solar project, inside AutoCAD
From site surface to engineering studies to the proposal — without jumping across ten tools.
Civil & earthwork
Grading, cut/fill, quantity takeoff, piling, and roads with drainage.
Electrical studies
DC stringing, short-circuit, protection, arc-flash, and grounding.
Substation & grid
MV/HV collector, substation, POI, and single-line diagram (SLD).
Data & optimization
Multi-provider weather, economics, and a multi-objective optimizer.
AI copilot
An assistant inside AutoCAD to speed up every step.
Electrical studies
Standards-backed electrical engineering, not a screenshot of the drawing
ELAP's differentiator: normative checks come out with the formula, the substitution, and a PASS/FAIL verdict — auditable engineering, not a black box. It's an evolving suite — we show what it delivers today, with each module's scope, not promises.
- DC stringing & MPPT
- Load-flow & short-circuit
- Protection coordination (IEC 60255 / TCC / N-1)
- Arc-flash IEEE 1584-2018
- Grounding IEEE 80
- MV/HV cable sizing
- Substation, GSU & POI
- BESS
- Single-line diagram (SLD)
- ETAP import (by scope)
Civil, terrain & structural
From survey to defensible earthwork
Real terrain and quantities that hold up under review — not an idealized plan.
- Terrain import — 5 formats + OSM obstacles
- Grading, cut/fill & earthwork takeoff
- Piling & foundation engine
- Roads, drainage & culverts (multi-standard)
- Geotechnical SPT/CPT
- Structural loads — wind/snow (ASCE) & lightning risk
Layout, data & AI
Iterate capacity with real data
Trackers & 3D preview
SAT, fixed-tilt, and TFT, multi-row, with a 3D park view.
PVsyst-domain shading
Near and far shading losses over the real terrain.
Multi-provider weather
PVGIS, NASA, Open-Meteo, NSRDB, and Solcast — with your own API key.
Multi-objective optimizer
Explore the Pareto front between capacity, cost, and buildability.
Shading
Move the sun and the shadow moves with it
NOAA solar position for the site, date and time you pick. The shadow each row casts and the shaded percentage come from the same sun vector — this is not a decorative animation.
Structure
- Sun elevation
- 14.2°
- Azimuth
- 48°
- Profile angle
- 20.6°
- Tilt
- 25°
- Shadow reach
- 8.1 m
- Row shaded
- 0 %
The relief is a grid from a sample site, run through the same exporter ELAP uses. The shading is measured by casting rays against the terrain and the neighbouring rows — the same engine that draws the scene. Publishing a project ships the grid of your own.

Who is it for?
One workflow, three ways to use it
Installer
Fast layout on real terrain and a core investment case to quote without redrawing.
Engineering studio
Full civil + electrical, with memos and unified export per project.
EPC / Developer
Substation, BESS, and studies to advance into project stages.
Plans
License, support, and activation — without noise
Public pricing, per seat, no mandatory sales calls — and you can try it for 30 days on your own project.
Questions
What people usually ask
Does it run inside my AutoCAD?
Yes. ELAP is an extension that runs inside AutoCAD; you work on your own DWG.
Are the electrical studies complete?
It's an evolving suite. We show what it delivers today and are explicit about each module's scope.
How do I activate the license?
You buy the plan and the subscription issues and activates the plugin key automatically.
Can I try it first?
Yes. Request a 30-day evaluation license and try it on your own project, or book a short demo.
